Translation: Azure Translator in Foundry Tools vs LLM translation flows
Session 36 of 40 · 45-minute session
Skills measured — Microsoft’s wording
  • Build solutions that translate text by using Azure Translator in Foundry Tools or LLM‑powered translation flows

Why This Matters

Translation looks like a solved problem until a customer letter goes out in the wrong register, or a contract term is rendered three different ways in one document. AI-103 asks you to build translation two ways, with Azure Translator in Foundry Tools and with an LLM-powered flow you design yourself, and to know when each is the right call. The line between them has moved: Translator’s newest API can now send a request to an LLM deployment, with tone and gender controls. Today you learn the Translator family, call it without a key, run the same text through your own prompt, and compare the results honestly.

IN YOUR SUBSCRIPTION
Creates
No new resource type. The Foundry resource in rg-ai103 already serves Translator. You add one model deployment on Global Standard for LLM translation, and two role assignments of Cognitive Services User on the Foundry resource: one for your own account and one for the resource’s own managed identity.
Cost
Billed. Learn states that standard NMT translation is billed by the number of characters in the source text, and LLM translation by the input and output tokens processed. The Responses call is billed per token as usual. Check the Azure pricing calculator and the Microsoft Foundry pricing page for current rates, and keep your test text short. Role assignments cost nothing.
Clean-up
Delete the model deployment when your evidence is saved, unless you go straight on to Session 37: Foundry portal → Build → Models → open it → delete, or az cognitiveservices account deployment delete --deployment-name <name> -n <resource> -g rg-ai103. Remove the role assignments under Access control (IAM) → Role assignments if you prefer. Keep rg-ai103 for the capstone.
The 45-Minute Session
7:00 – 16:00
The Translator family: text, documents, custom models
  • Text translation translates strings in real time. At the time of writing two versions are generally available: v3, the long-standing API, and 2026-06-06, the newest, which adds LLM choice, adaptive custom translation and more request parameters. Learn warns that 2026-06-06 includes breaking changes, so plan and validate any migration from v3.
  • Document translation keeps a file’s structure and format. Asynchronous batch translation needs an Azure Blob Storage account with source and target containers, authorised with a shared access signature (SAS) or a managed identity. Synchronous translation handles a single file, optionally with a glossary, needs no storage account, and returns the translated file directly.
  • In Python, batch document translation uses the azure-ai-translation-document package: a DocumentTranslationClient and its begin_translation method, which takes the source container URL, the target container URL and the target language, and returns a poller you wait on.
  • Custom Translator builds a customised neural translation model from your own parallel documents, for domain terminology and style. You train it, test it and deploy it, and updates follow a retrain-and-redeploy cycle. In 2026-06-06 you call a custom model by passing its category ID in deploymentName.
  • Adaptive custom translation (AdaptCT) is the lighter option. You upload aligned sentence pairs, the service builds an adaptive dataset in minutes, and at request time it retrieves similar pairs to guide an LLM’s terminology and style. Nothing is trained. A request passes an adaptiveDatasetId or up to five referenceTextPairs. In the Foundry portal it sits under Build → Models → AI Services → Azure Translator - Text Translation → Adaptive LLM.
  • THE EXAM LINE

    Custom Translator trains and deploys a dedicated NMT model from parallel documents. Adaptive custom translation trains nothing: it retrieves your reference pairs at request time to steer an LLM. Batch document translation needs Blob Storage; single-file synchronous translation does not.

  • A trap worth knowing: a scenario says “detect the language first”. In 2026-06-06 the Detect, BreakSentence and Dictionary Lookup operations are gone, and Learn’s migration page sends language detection to Azure Language. Translate itself still auto-detects the source when you leave out language.
When two names both contain “custom”, ask whether anything is being trained. That one question separates them.
24:00 – 37:00
Hands-on: the same text, three routes
  • Roles first. In the Azure portal, open your Foundry resource in rg-ai103 → Access control (IAM) → Add role assignment, and give your own account Cognitive Services User. Learn’s resource-configuration steps also assign Cognitive Services User to the Foundry resource’s managed identity (Members → Managed Identity → select your Foundry resource). Do both before you try an LLM target.
  • Deploy one GPT chat model on Global Standard, as in Session 4. Learn’s Translator examples use GPT-5.1, and the Translator languages call (get_supported_languages in the SDK) lists the models available for translation. Use the same deployment for both LLM routes so the comparison is fair. The last two variable names below are mine, not Microsoft’s.
  • bashsetup.shtype it yourself
    pip install "azure-ai-projects>=2.4.0" azure-identity requests
    az login
    
    export FOUNDRY_PROJECT_ENDPOINT="https://<resource-name>.services.ai.azure.com/api/projects/<project-name>"
    # Course-own names (not Microsoft's):
    export FOUNDRY_RESOURCE_ENDPOINT="https://<resource-name>.cognitiveservices.azure.com/"
    export TRANSLATION_LLM_DEPLOYMENT="<your-gpt-deployment-name>"
  • The script sends one sentence through all three routes. The Translator body follows the 2026-06-06 reference, the bearer-token call follows Learn’s custom-endpoint example, and the Responses call is the Week 1 pattern with the instructions parameter from Learn’s Responses how-to.

    # Route 3: your own LLM translation flow through the project's Responses API

    WHAT YOU SHOULD SEE
    Translator (NMT): <French from the NMT engine>
    Translator (LLM, formal): <French from your deployment, formal register>
    LLM flow: <French from your own prompt>
  • If the call returns 401 or 403, check the role assignment and that the endpoint is the custom domain form before you change any code. If only the LLM target fails, check the managed identity assignment and the deployment name, and confirm your resource has no private endpoint.
Use a sentence with a name, a date and an instruction-like phrase in it. Differences between engines show up fastest there.
42:00 – 45:00
Wrap-up: write it down, compare, clean up
  • Write down: text translation versus document translation; Custom Translator versus adaptive custom translation; the 2026-06-06 body (inputs, targets, deploymentName, tone, gender); the three authentication options; and when an LLM flow wins.
  • Your assignment: the same real text translated by all three routes, compared on accuracy, terminology, register and billing basis, with a production choice justified.
  • Clean-up: delete the model deployment once your evidence is saved, unless you go straight on to Session 37, which needs a chat model for its agent. Keep rg-ai103.
  • If every call still fails after you have checked roles, endpoint and deployment name, send me the exact error and a screenshot of the role assignments through “Ask R. Wingo” today.
Translation is judged by the reader. Before you submit, ask someone who reads the target language to rank your three versions.

Key Terms

Parallel documents

Pairs of documents, or sentences, with the same content in two languages, used to train or adapt translation.

Custom domain endpoint

A resource-specific address such as https://<resource-name>.cognitiveservices.azure.com, which accepts Microsoft Entra tokens.

Self-Check — Before You Submit
1. A hospital needs discharge letters translated into Spanish in a formal register, with gender-specific wording, and wants those controls as request settings rather than prompt text. What should it use?
  • A. Custom Translator with a trained model
  • B. Document translation in batch mode
  • C. Translator 2026-06-06 with an LLM deploymentName, tone and gender on the target
  • D. A small language model with a longer system prompt
C. Translator 2026-06-06 with an LLM deploymentName, tone and gender on the target — LLM-based Translator translation supports tone and gender as target parameters. Custom Translator trains an NMT model for terminology; it does not offer tone or gender controls.
2. A bank’s terminology team changes its preferred translations every week and wants each change live the same day, without retraining anything. Which option fits?
  • A. Adaptive custom translation
  • B. Custom Translator
  • C. Text translation v3 with a longer input
  • D. Document translation with a glossary in Blob Storage
A. Adaptive custom translation — Adaptive custom translation builds a dataset from sentence pairs in minutes and applies it at request time. Custom Translator requires a retrain-and-redeploy cycle, which is exactly what the team wants to avoid.
3. In a 2026-06-06 translate request, a target contains only "language": "fr". Which engine translates it?
  • A. The first LLM deployment in the Foundry resource
  • B. The last Custom Translator model you trained
  • C. No engine: the request fails without deploymentName
  • D. Neural machine translation, because deploymentName defaults to general
D. Neural machine translation, because deploymentName defaults to general — When deploymentName is omitted it defaults to general, Translator’s reserved name for NMT. An LLM or a custom model is used only when you name it in that target.

Today’s Assignment

Translate the same real text with Azure Translator in Foundry Tools and with your own LLM translation flow, compare the results, and justify which you would put into production.
  • Choose 150–300 words of real, non-confidential text from your work (a notice, a policy paragraph, a product description) and a target language you can check, or can have checked by someone who reads it.
  • Adapt translate_both.py so your text goes through three routes: Translator NMT, Translator with your LLM deployment (with a tone you choose), and your own Responses-based flow. Keyless only: Microsoft Entra tokens, and every value from environment variables.
  • Compare the three outputs in a table: accuracy, terminology, register, anything added or dropped, and the billing basis Learn states for each route.
  • Justify a production choice for this text in 150–250 words, and say when you would switch to Document translation, Custom Translator or adaptive custom translation instead.
  • Include your full code with placeholders only. Keep the explanation between 300 and 700 words. Crop keys, tokens and endpoints out of every screenshot, and never paste a key or token into the document.
  • Delete the model deployment afterwards, or say that you kept it for Session 37.
Evidence to include
  • Terminal output showing all three translations of your text.
  • A screenshot of the role assignments on your Foundry resource showing Cognitive Services User (crop IDs if you prefer).
  • A screenshot of the model deployment used for both LLM routes, with its name visible.

Skills measured — Microsoft’s wording
  • Implement workflows to convert speech to text and text to speech for agentic interactions
  • Integrate speech as an agent modality, including custom speech models

Why This Matters

An agent that can only type is closed to anyone driving, working with gloves on, or unable to use a keyboard. AI-103 expects you to give an agent ears and a voice: speech to text and text to speech with the Speech SDK, speech as an agent modality through the Voice Live API or the GPT Realtime API, and custom speech when the default model mishears your vocabulary. The exam tests the class names and when each route fits. At work, voice is where latency and misheard product names decide whether people keep using it. Today you build a keyless voice round trip to your own agent.

IN YOUR SUBSCRIPTION
Creates
One prompt agent version in your project, and one role assignment of Cognitive Services Speech User on your Foundry resource, which also serves Azure Speech. A chat model deployment on Global Standard (reuse Session 36’s if you kept it). A local WAV file holding the spoken reply. No custom speech model is trained today.
Cost
Billed. Speech to text and text to speech are billed by usage on the Foundry resource, and the agent’s model calls per token. Check the Azure Speech pricing page and the Microsoft Foundry pricing page before you start. Learn’s Voice Live page notes that custom speech, custom voice and custom avatar are charged separately for model training and hosting, so nothing of that kind is created today.
Clean-up
Delete the agent version with delete_version, as in Session 4, and the model deployment (Build → Models) once your evidence is saved, unless you go straight on to Session 38. Delete reply.wav if it holds anything private. Keep rg-ai103.
The 45-Minute Session
8:00 – 16:00
The Speech SDK: config, recognizer, synthesizer
  • The Python package is azure-cognitiveservices-speech, imported as speechsdk. Everything starts with a SpeechConfig. The quickstarts build it with subscription= (a key) and endpoint=. We will not use a key.
  • Keyless. Learn’s Microsoft Entra page builds the same object as SpeechConfig(token_credential=..., endpoint=...), passing a TokenCredential and the resource’s custom domain endpoint. Two conditions apply. The resource needs a custom domain name (creating one is not reversible); the quickstarts show a Foundry resource’s endpoint already in that form, https://<resource-name>.cognitiveservices.azure.com. And your identity needs Cognitive Services Speech User or Cognitive Services Speech Contributor.
  • Listening. Set speech_recognition_language (for example en-US), create an AudioConfig (the default microphone, or filename= for a WAV file), then a SpeechRecognizer. recognize_once_async().get() transcribes one utterance of up to 30 seconds, or until silence is detected. Check result.reason: RecognizedSpeech, NoMatch or Canceled. For longer audio, the how-to uses continuous recognition.
  • Speaking. Set speech_synthesis_voice_name; the quickstart uses en-US-Ava:DragonHDLatestNeural, in the format {locale}-{VoiceName}:{VoiceType}. Create an AudioOutputConfig (the default speaker, or filename=) and a SpeechSynthesizer, call speak_text_async(text).get(), and check for SynthesizingAudioCompleted.
  • THE EXAM LINE

    SpeechConfig holds the endpoint and credential. SpeechRecognizer with recognize_once_async transcribes one utterance; SpeechSynthesizer with speak_text_async speaks text. Keyless means token_credential, a custom domain endpoint and a Speech role.

Always branch on result.reason. In a voice app, a silent failure sounds exactly like a slow answer.
28:00 – 37:00
Speech as an agent modality: Voice Live and Realtime
  • The Voice Live API gives you speech in and speech out through one managed WebSocket interface. Its feature list includes noise suppression, echo cancellation, robust interruption detection, advanced end-of-turn detection, avatar integration, function calling, and support for custom voice and custom speech. Its supported models include the gpt-realtime family and a range of GPT chat models; the list changes, so check the page.
  • In agent mode, Voice Live fronts a Foundry agent. Learn’s quickstart installs azure-ai-voicelive, passes an AgentSessionConfig (agent name, optional version, project name) to connect(...), and keeps voice settings such as the voice, turn detection, noise suppression and echo cancellation in the agent’s metadata. Your account needs Foundry User.
  • THE EXAM LINE

    Voice Live agent mode doesn’t support key-based authentication for agent invocation; use Microsoft Entra ID. Voice Live events mostly match the Azure OpenAI Realtime API events, with some exceptions.

  • The GPT Realtime API is the model-level route. Learn recommends WebRTC in most cases for low-latency audio streaming, WebSocket for server-to-server work, and SIP for telephony. Use the GA endpoint with /openai/v1 in the URL, not a date-based API version.
  • Illustrative: a hospital booking line already runs a Foundry agent with tools and a guardrail. Voice Live in agent mode puts a voice in front of that same agent, so its tools and controls still apply. A new web page that only needs a spoken chat with a model is a natural fit for the Realtime API over WebRTC.
When a question mentions an existing agent and a voice, prefer the answer that keeps the agent. Rebuilding it around a new model is rarely right.
42:00 – 45:00
Wrap-up: write it down, then clean up
  • Write down: the three voice routes and when each wins; SpeechConfig, SpeechRecognizer, recognize_once_async, SpeechSynthesizer, speak_text_async; the keyless recipe (custom domain, a Speech role, token_credential); and the custom speech workflow ending in WER and a custom endpoint.
  • Your assignment is a keyless voice round trip to your own agent, with transcripts, spoken replies and a short design note.
  • Clean-up: delete the agent version and, unless you go straight on to Session 38, the chat model deployment. Keep rg-ai103.
  • Microphone or audio driver trouble is a blocker. Tell me the same day, with the exact error, rather than losing an evening to it.
Voice makes an agent feel finished long before it is. Test it in the quietest and the noisiest room you can find.

Key Terms

Neural voice

A synthetic voice produced by deep neural networks, named by locale, voice and voice type.

Speech-to-speech

An interaction where audio goes in and audio comes out, with no typed text in between for the user.

Self-Check — Before You Submit
1. A logistics firm wants drivers to talk hands-free to its existing Foundry booking agent, with noise suppression and interruption handling, without building the audio pipeline itself. What should it use?
  • A. Batch transcription with a custom speech model
  • B. The Voice Live API in agent mode
  • C. Azure Translator in Foundry Tools
  • D. SpeechSynthesizer on its own
B. The Voice Live API in agent mode — Voice Live is a managed speech-to-speech service with noise suppression and interruption detection, and its agent mode fronts an existing Foundry agent. Batch transcription processes files afterwards and cannot hold a live conversation.
2. Your Speech SDK app must run with no key anywhere. Which set-up does Learn document?
  • A. SpeechConfig(subscription=..., region=...) with the key in an environment variable
  • B. SpeechConfig with no arguments, relying on az login
  • C. An AudioConfig with a token file
  • D. SpeechConfig(token_credential=..., endpoint=custom domain endpoint), with a Speech role on the resource
D. SpeechConfig(token_credential=..., endpoint=custom domain endpoint), with a Speech role on the resource — The Entra page builds SpeechConfig from a TokenCredential and the custom domain endpoint, and requires Cognitive Services Speech User or Contributor. A key in an environment variable is still a key.
3. A clinic’s transcripts keep misrecognising drug names. What is the right fix, and how do you prove it worked?
  • A. Custom speech: train on domain data, compare word error rate before and after, deploy to a custom endpoint
  • B. Change the synthesis voice to a neural HD voice
  • C. Switch recognize_once_async to speak_text_async
  • D. Translate the transcript with Custom Translator
A. Custom speech: train on domain data, compare word error rate before and after, deploy to a custom endpoint — Custom speech exists to improve recognition of domain terms, and word error rate measures the improvement. Synthesis voices and translation do not change what the recogniser hears.

Today’s Assignment

Build a keyless voice round trip to your own agent (speech in, agent answer, speech out) and explain how you would take it to production.
  • Use a prompt agent of your own, with instructions for a task from your work. Adapt voice_roundtrip.py, keeping DefaultAzureCredential and the custom domain endpoint, and read every value from environment variables.
  • Ask two spoken questions, one in a quiet room and one with background noise, and keep both transcripts, both agent answers and both reply files.
  • Explain (300–700 words): how each class is used; why no key is needed and which role makes it work; what the recogniser got wrong, if anything; and whether you would move to the Voice Live API or the GPT Realtime API for production, and why.
  • Say whether custom speech would help this use case, what data you would train it on, and how you would measure the improvement.
  • Include your full code with placeholders only. Never include keys, tokens or endpoints in the code, the document or screenshots. Delete the agent version afterwards and say so.
Evidence to include
  • Terminal output of both runs showing the recognised text and the agent’s answer.
  • A screenshot of the two reply WAV files in your folder with their sizes, and one sentence on how each sounded.
  • A screenshot of the Cognitive Services Speech User role assignment on your Foundry resource.

Skills measured — Microsoft’s wording
  • Enable multimodal reasoning from audio inputs
  • Translate speech into other languages by using language models and Foundry Tools

Why This Matters

Some answers live in the sound itself: whether a caller sounded pressured, whether a spoken instruction contradicts the written one, what was said in a language nobody on the team speaks. AI-103 expects you to enable reasoning over audio with an audio-capable model, and to translate speech with both language models and Foundry Tools. The exam checks the request shape, the classes and which route fits; the job adds cost and accuracy trade-offs. Today you send a recording straight to a model, translate the same recording with the Speech SDK, and learn where LLM Speech, Live Interpreter and real-time translation fit.

IN YOUR SUBSCRIPTION
Creates
One audio-capable model deployment on your Foundry resource. Learn’s quickstart uses gpt-4o-mini-audio-preview; choose an audio model and a deployment type that the portal offers in your region. Speech translation uses the Foundry resource you already have and the Cognitive Services Speech User role from Session 37. Your recording and the output audio stay on your machine.
Cost
Billed. The audio model call is billed on its deployment like any model call, and speech translation by usage on the Foundry resource. Check the Microsoft Foundry pricing page for the model you chose and the Azure pricing calculator for Speech. Keep recordings short: ten to twenty-five seconds is plenty.
Clean-up
Delete the audio model deployment once your evidence is saved: Build → Models → open it → delete. Delete any output WAV files that hold private speech. Keep rg-ai103 for the capstone.
The 45-Minute Session
7:00 – 19:00
Hands-on: send a recording to an audio-capable model
  • Learn’s audio quickstart describes audio-enabled models as adding the audio modality to the existing /chat/completions API, with text, audio, or both as modalities. Support for audio completions was first added in API version 2025-01-01-preview, which its sample uses.
  • The request is a user message whose content has a text part (your question) and an input_audio part with the base64 data and its format, such as wav. With modalities=["text", "audio"] the answer comes back as audio, and its text is in message.audio.transcript.
  • Deploy the audio model from Discover → Models, as in Session 4. The client follows the quickstart’s keyless Python sample: AzureOpenAI with azure_ad_token_provider. AZURE_OPENAI_ENDPOINT is Learn’s variable name for your resource’s https://<resource-name>.openai.azure.com/ endpoint; AUDIO_MODEL_DEPLOYMENT is mine.

    WHAT YOU SHOULD SEE
    - The speaker wants <what your recording asks for>
    - They sound <the tone the model heard>
    - <whether anything was promised>
  • Now change the text part to “Translate what the speaker says into French” and run it again. That is the language-model route to speech translation, in one call.
  • A trap: input_image is the image part, input_audio the audio part, and a deployment whose model does not accept audio has no way to use it. Check the model card’s input types first.
Test with a recording where the words and the tone disagree. That is where audio reasoning earns its cost.
30:00 – 40:00
Speech translation with language models, and how to choose
  • LLM Speech is an API in Microsoft Foundry in which a large language model enhances a speech model. It has two tasks: transcription, and translation into a target language. You send the audio file to the fast transcription endpoint (.../speechtotext/transcriptions:transcribe) with a definition whose enhancedMode sets the task, plus an optional prompt to guide the output style. Learn’s Speech overview marks it as preview, so check its status before production.
  • jsonllm-speech-definition.jsontype it yourself
    {
      "enhancedMode": {
        "enabled": true,
        "task": "translate",
        "targetLanguage": "ko"
      }
    }
  • At the time of writing, LLM Speech translates into a short list of target languages (German, English, Spanish, French, Italian, Korean, Japanese, Portuguese and Chinese). Check yours is there before you design around it.

  • THE EXAM LINE

    Speech translation comes from Foundry Tools (the Speech SDK, Live Interpreter) or from language models (LLM Speech with task translate, audio-capable chat models, gpt-realtime-translate). Custom speech models also work for speech translation.

  • The honest trade-off: a language model can smooth over a mumbled phrase and produce fluent text the speaker never said. For anything regulated, keep the source transcript beside the translation, and have a speaker of the language spot-check it.
Choose by the shape of the input: a live stream, a file, or a question about a file.

Speech to text translation

Recognising speech in one language and returning text in another.

Language identification

Working out which language is being spoken in audio, instead of being told in advance.

Self-Check — Before You Submit
1. An insurer wants one request that says, from a recorded claims call, what the caller asked for and whether they sounded distressed. What fits best?
  • A. A TranslationRecognizer with two target languages
  • B. Custom speech trained on claims vocabulary
  • C. An audio-capable chat model with the recording as an input_audio part
  • D. Text to speech with a neural HD voice
C. An audio-capable chat model with the recording as an input_audio part — Tone is in the audio, so the model must receive the audio itself, which an audio-capable chat model accepts as input_audio. Custom speech improves transcription accuracy but judges nothing about how the caller sounded.
2. Which result reason tells you a Speech SDK translation succeeded?
  • A. RecognizedSpeech
  • B. TranslatedSpeech
  • C. SynthesizingAudioCompleted
  • D. NoMatch
B. TranslatedSpeech — TranslationRecognizer results carry ResultReason.TranslatedSpeech on success. RecognizedSpeech is the tempting one, but it belongs to plain speech to text with SpeechRecognizer.
3. A conference wants delegates to speak in any language, switch language mid-session, and hear a natural-voice translation in real time, without anyone setting the input language. Which capability matches?
  • A. LLM Speech with task set to translate
  • B. Document translation
  • C. Custom Translator
  • D. Live Interpreter
D. Live Interpreter — Live Interpreter identifies the spoken language, handles switching, and delivers low-latency speech-to-speech translation. LLM Speech translates audio files and returns text, not live speech.

Today’s Assignment

Record one short clip, reason over it with an audio-capable model, translate it with the Speech SDK, and compare the two routes.
  • Record a 10–25 second WAV clip of your own voice (no one else’s, nothing private) that contains a request and a clear tone, as if a customer or colleague were speaking.
  • Run audio_reason.py with two prompts of your own: one reasoning question about the clip, and one asking for a translation into a language you can check.
  • Run speech_translate.py on the same clip with two target languages. Keyless only, with every value from environment variables.
  • Compare, in 300–700 words: the model’s translation against the Speech SDK’s; what the model noticed that a transcript would miss; which route you would choose for a real use at your work, and why; and where LLM Speech, Live Interpreter or gpt-realtime-translate would fit instead.
  • Include your full code with placeholders only. Never include keys, tokens or endpoints in the document or screenshots. Delete the audio deployment afterwards and say so.
Evidence to include
  • Terminal output of audio_reason.py for both prompts.
  • Terminal output of speech_translate.py showing the recognised text and both translations.
  • A screenshot of the audio model deployment, with its name, model and version visible, taken before you deleted it.
Names your answer must use exactly

Never include a key, a connection string or a token. Crop them out of every screenshot. If one is exposed, the letter will tell you to rotate it.

Why This Matters

You have now met every objective on the AI-103 outline. The exam will not ask them in course order, and it will not tell you which session a question came from. This session puts the whole outline in front of you, domain by domain, so you can separate the bullets you can explain and build from the ones you merely recognise. It also sets out, from Microsoft’s own pages, what the exam is like to sit: the time, the breaks, the question types and the Learn access you get. Then you sit Practice Exam 2 under real conditions and build an honest register of what still needs repair.

IN YOUR SUBSCRIPTION
Creates
Nothing. This is a review session.
Cost
Nothing new is billed today. Use the time to check Cost analysis for anything still running from Weeks 5 to 8: a model deployment, a search service or a custom endpoint you forgot.
Clean-up
Delete any leftover model deployments, and any resource you created outside rg-ai103. Keep rg-ai103 and its project for the Session 40 capstone.

  • Answer aloud: which deployment type keeps inference inside the EU and bills per token? Which role is least privilege for a developer? Which guardrail does an agent use when none is assigned to it? What must you do to stop spending, given that a budget will not?
  • THE EXAM LINE

    Domain A traps: Global Standard versus Data Zone Standard; Serverless API versus Managed compute; a budget alert that stops nothing; and an agent guardrail that fully overrides its model’s guardrail instead of adding to it.

  • Pairs the exam likes to set against each other: Azure Content Understanding in Foundry Tools and Azure Document Intelligence in Foundry Tools; Custom Translator and adaptive custom translation; the Voice Live API and the GPT Realtime API; Speech SDK translation and LLM Speech.
  • THE EXAM LINE

    Learn describes Document Intelligence as giving deterministic extraction from structured documents, and Content Understanding as also offering LLM-powered analyzers for complex, unstructured and multimodal content. Read the input type before you choose.

  • These three domains are smaller one by one, but together they carry at least as much weight as Domain B. Candidates who skim them because each is “only 10–15%” lose real marks.
For every vision or speech bullet, name the input, the output and the service in one sentence. If you cannot, it is amber.

  • Clean-up: check Cost analysis and rg-ai103 for anything still running, and delete it. Keep the resource group and project for the capstone.
  • Session 40 is the capstone and the marked Final. Start the capstone once your register is written; it will tell you where to be careful.
A register with three honest reds is worth more than one with twenty vague ambers.

Your list of objectives you cannot yet explain and build, each with its evidence, a repair page and a date.

Self-Check — Before You Submit
1. During an associate exam you mark question 12 for review, then take a break after question 20. What happens to question 12?
  • A. It stays open until you finish the exam
  • B. You cannot return to it, because questions viewed before a break are closed
  • C. It is removed from your score
  • D. The clock pauses so you can review it first
B. You cannot return to it, because questions viewed before a break are closed — Microsoft states that once a break is launched you cannot return to questions viewed before it, even if they are marked for review. The clock also keeps running during breaks, so it never pauses for you.
2. A manufacturer needs deterministic field extraction from thousands of structured purchase orders, and separately wants LLM-powered analysis of mixed video, audio and unstructured files. Which pairing fits?
  • A. Azure Translator in Foundry Tools for both
  • B. Foundry IQ for the orders, the Semantic ranker for the media
  • C. Azure Document Intelligence in Foundry Tools for the orders, Azure Content Understanding in Foundry Tools for the mixed files
  • D. Azure Content Understanding in Foundry Tools for the orders, Azure Speech in Foundry Tools for the mixed files
C. Azure Document Intelligence in Foundry Tools for the orders, Azure Content Understanding in Foundry Tools for the mixed files — Learn describes Document Intelligence as deterministic extraction from structured documents and Content Understanding as offering LLM-powered analyzers for unstructured and multimodal content. Speech handles audio only, not video or documents.
3. An agent has no custom guardrail assigned. Its model deployment uses a custom guardrail named strict-finance. Which guardrail applies to the agent?
  • A. Microsoft.DefaultV2, always
  • B. None: agents need their own guardrail
  • C. Both, merged
  • D. strict-finance, inherited from its model deployment
D. strict-finance, inherited from its model deployment — With no custom guardrail assigned, an agent inherits the guardrail of its model deployment. Microsoft.DefaultV2 applies only if the deployment uses it or it is assigned explicitly.

Today’s Assignment

Build a weak-spot register from your own results, with the Learn page that repairs each gap and a dated repair plan.
  • Gather your results: Practice Exam 2, Practice Exam 1, the six pop quizzes, and today’s traffic-light drill of all 64 bullets.
  • List at least eight red or amber bullets, however well you did. For each: the bullet as the study guide words it, the session that taught it, the questions you missed on it, and an honest diagnosis (did not know the name, confused two services, knew it but misread the scenario).
  • For each entry give the specific Learn page that repairs it (a how-to, quickstart or concept page, not the study guide), the exact names you must be able to produce afterwards, and a repair date before you sit the marked Final.
  • Add a short “confused pairs” section: one line each on how to tell Azure Content Understanding in Foundry Tools from Azure Document Intelligence in Foundry Tools, and Global Standard from Data Zone Standard, plus one pair of your own choosing.
  • Add a paragraph on exam technique: your Practice Exam 2 timing, where you lost time, and what you will change, using what Microsoft’s exam-experience page says about breaks, review and Learn access.
  • Keep the explanation between 300 and 700 words, plus the register table. No keys, secrets or credentials anywhere, and no one else’s details in any screenshot.
  • End with one line on clean-up: what you found still running, and what you deleted.
Evidence to include
  • A screenshot of your Practice Exam 2 result showing the score and the breakdown the course gives you.

Why This Matters

This is where the course stops asking whether you know the names and asks whether you can ship with them. The capstone is one small solution in your own subscription, built the way a careful team would build it: a grounded agent with a tool, no keys anywhere, a guardrail, tracing you can read and an evaluation you can defend. It touches every domain of AI-103, and it is work a hiring manager can actually look at. Then you sit The Marked Final, clean up for the last time, and book the real exam with Microsoft.

IN YOUR SUBSCRIPTION
Creates
In rg-ai103: a chat model deployment on Global Standard; an Application Insights resource connected to your project (or the Session 17 one, if you kept it); a vector store holding your document, and a prompt agent with the file search tool; a custom guardrail; an uploaded evaluation dataset and one evaluation run. Role assignments as Learn lists them: Foundry User on the project, Storage Blob Data Contributor on the project’s storage account for uploads, and Log Analytics Reader to query traces.
Cost
Billed. The agent’s model calls and the AI-assisted evaluator are billed per token on your deployment; file search and Application Insights have their own pricing. Check the Microsoft Foundry pricing page and the Azure pricing calculator, keep the document short and the dataset to five to ten queries, and watch Cost analysis while the capstone is running.
Clean-up
When the capstone is marked and the Final is sat, delete everything: Azure portal → Resource groups → rg-ai103 → Delete resource group, or az group delete --name rg-ai103. A deleted Foundry resource is soft-deleted: you cannot create one with the same name for 48 hours unless you purge it (Manage deleted resources → Purge), and charges for any provisioned deployments continue until it is purged. Then remove the course budget: Subscriptions → your subscription → Budgets. Finally, run az group list as in Session 20, delete anything the course created outside rg-ai103, and make sure the Session 22 GitHub workflow is disabled.
The 45-Minute Session
6:00 – 18:00
Build: a grounded agent, keyless, with tracing on
  • Connect tracing first, because Foundry’s out-of-the-box traces start once tracing is enabled. In the Foundry portal select Agents, then Traces at the top, then Connect to create or connect an Application Insights resource. Give yourself Log Analytics Reader so you can query what arrives.
  • Check the roles Learn’s file search page lists: Foundry User on the project, and Storage Blob Data Contributor on the project’s storage account for uploads. Then install the tracing packages. Learn’s agent evaluation how-to asks for azure-ai-projects 2.4.0 or later, the floor you moved to in Session 9; the upgrade below makes sure.

  • Foundry logs server-side traces for prompt agents automatically once tracing is enabled; the client-side lines add your own span and instrument the Responses calls your code makes. Learn warns that recording message content captures user messages, tool arguments and model outputs, so leave OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT unset unless you are in a development environment with harmless data.
  • Each run creates a new agent version and vector store, so note the values printed each time: the clean-up script needs them.
An instruction that says what to do when the answer is missing is the cheapest grounding control you will ever write.

Observe and evaluate
  • Traces. Select Agents → Traces, search by a response ID your script printed, open the trace and step through its spans. Select the Conversation ID to review the history, tokens, actions and tool calls. Find the file search call.
  • Evaluation. Write test-queries.jsonl with five to ten lines such as {"query": "..."}, mixing questions the document answers with ones it does not. Set AGENT_VERSION to the version you are evaluating. The script follows Learn’s Evaluate your AI agents how-to: it uploads the dataset, creates an evaluation with a quality evaluator (builtin.coherence) and a safety evaluator (builtin.violence), and runs it with your agent as the target.

  • THE EXAM LINE

    An agent evaluation run uses the data source type azure_ai_target_completions with an azure_ai_agent target, and TestingCriterionAzureAIEvaluator names each built-in evaluator. Results open under the Evaluations tab through report_url.

  • Read the report, not just the status. If a score is low, open that row, find its trace, and say in your design note what you would change: the instructions, the document, the tool or the guardrail.
Evaluate the questions your agent should decline as well as the ones it should answer. Declining is a behaviour too.

Wrap-up: The Marked Final, the certificate, the gift and the real exam
  • This session opens The Marked Final. It is served and marked on the server, and every sitting is a fresh draw: 50 questions in 100 minutes, scored out of 1000, with 700 to pass. Resits are unlimited and your best score counts. Submit your capstone first, then sit it under exam conditions.
  • The certificate rule. You receive the certificate of completion, with a reference letter from me, when your capstone is marked at 70 or above and your marked Final is 700 or above. Both, not either.
  • The completion gift. When your capstone passes, I email you a claim link for The Intelligent Barrel, the full book, with its three bonus PDFs: The Reader’s Toolkit, The 90-Day AI Pilot Charter & Playbook, and The Value–Risk Map & Autonomy Playbook. The claim code only works for existing customers, so check out with the same email address you used to buy this course.
  • Final clean-up. Once the capstone is marked and the Final is sat, delete rg-ai103 (Resource groups → rg-ai103 → Delete resource group), confirm it has gone, and remove the course budget. Then check az group list for anything the course created elsewhere, and disable the Session 22 GitHub workflow and delete its repository secrets if you have not already.
  • Booking AI-103. Open Microsoft’s page for Microsoft Certified: Azure AI Apps and Agents Developer Associate on Microsoft Learn (learn.microsoft.com/credentials/certifications/azure-ai-apps-and-agents-developer-associate) and select Schedule exam. The page says you schedule through Pearson Vue and that the price depends on the country or region where the exam is proctored. Microsoft strongly recommends registering with a personal Microsoft account, because records tied to a work or school account can be lost if you leave. Try the exam sandbox and the free Practice Assessment first.
  • When you pass the real exam, tell me through “Ask R. Wingo”. Once I record it, you can review the course for the students who come after you.
You built it, ran it and named it exactly. Now go and prove it where it counts.

Key Terms

Grounded answer

An answer drawn from supplied sources, such as your uploaded document, rather than the model’s general knowledge.

Soft delete

Deletion that keeps a resource recoverable for a period; its name stays reserved until it is purged.

Self-Check — Before You Submit
1. An agent has a custom guardrail assigned, and its model deployment uses Microsoft.DefaultV2. Which guardrail governs the agent?
  • A. Microsoft.DefaultV2, because model guardrails always apply
  • B. Both, applied one after the other
  • C. The agent’s custom guardrail, which fully overrides the model’s
  • D. Neither, until the agent is published
C. The agent’s custom guardrail, which fully overrides the model’s — Learn states that risks are detected based on the guardrail assigned to the agent, which fully overrides the model’s guardrail. The model’s Microsoft.DefaultV2 is not layered on top of it.
2. You call AIProjectInstrumentor().instrument() but see no client-side GenAI spans. Which environment variable must be set to true before that call?
  • A. AZURE_EXPERIMENTAL_ENABLE_GENAI_TRACING
  • B. OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT
  • C. FOUNDRY_PROJECT_ENDPOINT
  • D. AZURE_TRACING_GEN_AI_INCLUDE_BINARY_DATA
A. AZURE_EXPERIMENTAL_ENABLE_GENAI_TRACING — The client-side tracing page says AZURE_EXPERIMENTAL_ENABLE_GENAI_TRACING must be true before instrument() is called. The message-content variable only controls whether content is recorded, not whether tracing is on.
3. A public agency wants to evaluate its deployed prompt agent in the cloud against a file of citizen questions, and view the scores in the Foundry portal. Which approach matches Learn’s how-to?
  • A. Upload the file to Blob Storage and open it in the playground
  • B. Run the questions through the Model leaderboard
  • C. Assign a guardrail and read its annotations
  • D. Create an eval, then a run with data source type azure_ai_target_completions and an azure_ai_agent target, and open report_url
D. Create an eval, then a run with data source type azure_ai_target_completions and an azure_ai_agent target, and open report_url — Learn’s agent evaluation how-to creates an evaluation with testing criteria, then a run whose azure_ai_target_completions data source targets the agent, and links the results through report_url. A guardrail blocks risks; it does not score quality.

Today’s Assignment

Build, evidence and clean up a small end-to-end solution in your own subscription: a grounded agent with a tool, keyless authentication, a guardrail, tracing and an evaluation run, delivered with a design note.
  • Choose a use case from your own work and a short, non-confidential document. Build the agent with FileSearchTool over that document, starting from capstone_agent.py, using DefaultAzureCredential and environment variables only.
  • Connect Application Insights, enable tracing, and show one traced run in the Foundry traces view with the file search call visible.
  • Create a custom guardrail with at least two controls, assign it to the agent, and test one prompt that is blocked and one that passes.
  • Run an evaluation over at least five queries with at least one quality and one safety evaluator, and interpret the report.
  • Write the design note in 300–700 words: use case, architecture, every service and SDK class named exactly, how keyless authentication and the roles work, what the guardrail, trace and evaluation showed, what you would change next, and the clean-up you did.
  • Clean up: delete the agent versions and vector stores, and (after the Final) the resource group, and show it.
  • Include your full code with placeholders only. Never include keys, tokens, connection strings or endpoints in the code, the note or screenshots; crop them out.
Evidence to include
  • Terminal output of capstone_agent.py showing the agent version, a grounded answer and a correct decline.
  • Screenshots of the guardrail’s controls and agent assignment, and of the playground blocking a test prompt.
  • A screenshot of one trace under Agents → Traces showing its spans, including the tool call.
  • The output of capstone_eval.py and a screenshot of the report under Evaluations.
  • A screenshot showing the clean-up: the agent and vector store removed, or rg-ai103 gone.
Names your answer must use exactly
FileSearchTool AIProjectInstrumentor Log Analytics Reader TestingCriterionAzureAIEvaluator azure_ai_target_completions Create Guardrail Annotate and block
Never include a key, a connection string or a token. Crop them out of every screenshot. If one is exposed, the letter will tell you to rotate it.
How this is marked — the rubric
The agent works end to end: grounded answers from the document through the file search tool, a correct decline, and keyless authentication throughout25
The guardrail, tracing and evaluation are each configured and shown working, with results interpreted and a sensible next change25
The design note uses the exact names for every service and SDK class used, and explains roles and authentication correctly20
Evidence: outputs and screenshots for every part, with no keys, tokens or connection strings visible20
Clean-up is done deliberately and shown10
