FREE AI-102 Exam Guide 2026: Pass Microsoft Azure AI Engineer (GenAI, Azure OpenAI, Vision, NLP)

AI-102 Exam Guide 2026: The Azure AI Engineer Credential Built Around Azure OpenAI and Generative AI

Retirement Notice (updated July 2026): Microsoft retired Exam AI-102 and the Azure AI Engineer Associate certification on June 30, 2026. You can no longer schedule or sit AI-102. Its replacement is Exam AI-103: Developing AI Apps and Agents on Azure, which earns the Microsoft Certified: Azure AI Apps and Agents Developer Associate credential (in beta through mid-2026). This guide stays valuable because (a) the AI-102 body of knowledge overlaps roughly 75-80% with AI-103, (b) professionals who earned the credential before retirement must still renew it yearly, and (c) the Azure OpenAI, RAG, and Microsoft Foundry material here maps directly onto AI-103. Where AI-103 diverges (heavier agentic and Microsoft Foundry emphasis), we flag it.

In 2026 there is no Microsoft role-based certification more in flux - or more worth sitting - than Exam AI-102: Designing and Implementing a Microsoft Azure AI Solution. Microsoft revised the AI-102 skills outline multiple times since 2024 to add Azure OpenAI Service, retrieval-augmented generation (RAG), Microsoft Foundry (formerly Azure AI Studio, then Azure AI Foundry), Azure AI Search (formerly Azure Cognitive Search), and agentic/generative workflows. The exam that existed in 2022 covered Cognitive Services and Bot Framework; the final 2026 exam covered those plus a full generative AI and agentic chapter that candidates coming from older study guides completely missed.

This guide is written for the final AI-102 exam window (skills measured as of December 23, 2025, the last revision before the June 30, 2026 retirement). It maps every skill domain against that final outline, calls out the Azure OpenAI / RAG / agentic material, and gives you an 8-week plan, hands-on lab checklist, and career/salary context for the Azure AI Engineer Associate credential - plus transition notes for AI-103.

Who AI-102 Was For (and Who AI-103 Is For)

AI-102 is retired, but its target audience carries directly to the replacement AI-103 exam. The Microsoft skills outline targets developers who build AI solutions using Azure services, including the Azure OpenAI Service, Azure AI services (formerly Cognitive Services), Azure AI Search, Azure AI Document Intelligence, Azure AI Vision, Azure AI Language, Azure AI Speech, and Microsoft Foundry (formerly Azure AI Studio / Azure AI Foundry) for generative and agentic workloads.

Recommended Prerequisites (Not Required)

AI-102 has no formal prerequisites, but Microsoft strongly recommends candidates complete or have equivalent experience with:

• Exam AI-900 (Azure AI Fundamentals) - the conceptual foundation
• 1-2 years developing in Python or C# - both languages appear in code-read items
• Familiarity with REST APIs, JSON, authentication patterns (API key, Entra ID / Managed Identity)
• Basic Azure portal, Azure CLI, and Bicep/ARM navigation
• Conceptual understanding of machine learning (training vs inference, embeddings, vector search)

If you are brand new to Azure AI, sit AI-900 first (2 weeks of prep, $99) before starting on AI-102.

AI-102 Skills Measured (2026 Domain Weights)

The final Microsoft Learn skills outline for AI-102 (as of December 23, 2025) splits the exam into six weighted domains. Microsoft historically updated AI-102 more frequently than any other role-based exam - four to five outline revisions since the exam launched. The final revision reflects the maturation of Azure OpenAI, the rebranding of Cognitive Services into Azure AI services, the rename of Azure AI Foundry to Microsoft Foundry, and the addition of a dedicated agentic solution domain.

Sections below are presented in a study-friendly sequence; Microsoft's official outline lists generative AI as Domain 2 and agentic as Domain 3. Weights are identical either way.

IMPORTANT 2026 CAVEAT: AI-102 is now retired (June 30, 2026). The weights above are the final December 23, 2025 outline. Compared with earlier 2024-2025 outlines, the most significant change is the removal of the old "Implement decision support solutions" domain (Content Safety and moderation moved into Domain 1) and the addition of the new "Implement an agentic solution" domain (Domain 3) reflecting Microsoft Foundry Agent Service and Microsoft Agent Framework. For the successor exam, see the AI-103 study guide on learn.microsoft.com.

Source: Microsoft AI-102 Study Guide, final revision dated December 23, 2025.

Domain 1: Plan and Manage an Azure AI Solution (20-25%)

This domain is where DP-900/AI-900 alumni often under-prepare. It is architecture and operations, not model code.

Select the appropriate Azure AI service

• Choose between single-service vs multi-service (Azure AI services) resources for cost and key management.
• Decide between Azure AI services, Azure OpenAI, Azure Machine Learning, and Microsoft Foundry based on workload (prebuilt vs custom vs generative).
• Understand regional availability - Azure OpenAI is restricted to specific regions (East US, East US 2, Sweden Central, West Europe, Japan East, and others that rotate).

Plan, configure, and secure an AI solution

• Configure authentication: key-based vs Microsoft Entra ID (formerly Azure AD) with Managed Identity and Key Vault.
• Implement private endpoints and VNet integration for data exfiltration protection.
• Apply Customer-Managed Keys (CMK) with Key Vault for encryption at rest.
• Enable diagnostic logging to Log Analytics, Event Hub, or storage.
• Rotate keys programmatically and use Key Vault references in apps.

Implement responsible AI

• Apply the Microsoft Responsible AI Standard v2 six principles (fairness, reliability/safety, privacy/security, inclusiveness, transparency, accountability).
• Configure content filtering in Azure OpenAI (default low-severity thresholds, custom categories, jailbreak detection, protected material detection).
• Use Azure AI Content Safety for image/text moderation (hate, sexual, violence, self-harm) and prompt shield.
• Implement responsible AI metrics and human review workflows.

Manage, monitor, and optimize cost

• Use Azure Monitor and Application Insights for telemetry.
• Track token usage and throughput units (PTUs) in Azure OpenAI.
• Choose between pay-as-you-go and Provisioned Throughput Units (PTUs) for Azure OpenAI.
• Understand deployment options: Standard (shared capacity), Provisioned Managed, Global Standard, Global Batch.

Deploy Azure AI services in containers

• Deploy eligible services (Text Analytics, Language, Translator, Speech, Document Intelligence, AI Vision Read) as Docker containers on-prem or in Azure Kubernetes Service for data residency.

Domain 2: Implement an Agentic Solution (5-10%) - NEW in the December 23, 2025 Outline

This is the newest domain, added in the final outline revision before retirement. It reflects Microsoft's shift toward agent-based generative AI workloads. Expect items on the Microsoft Foundry Agent Service and Microsoft Agent Framework.

• Microsoft Foundry Agent Service: managed agents with function calling, code interpreter, file search, and Bing grounding (the successor to the Azure OpenAI Assistants API with enterprise security).
• Microsoft Agent Framework: build complex, multi-agent solutions with orchestration across multiple users and autonomous capabilities.
• Agent design: understand the role and use cases of an agent, configure the necessary resources, and create an agent in Foundry.
• Test, optimize, and deploy an agent including orchestration for multi-agent solutions.

Note (content moved from the retired "Decision Support" domain): The earlier AI-102 outline had a 10-15% "Implement decision support solutions" domain covering content moderation. That content was folded into Domain 1 ("Implement AI solutions responsibly") as of December 23, 2025. The key items to know:

• Azure AI Content Safety: text moderation (hate/sexual/violence/self-harm categories with severity 0/2/4/6), image moderation, Prompt Shields (jailbreak + indirect prompt injection detection), Protected Material detection (text copyright + code from public repos), Groundedness detection (hallucination detection).
• Personalizer (in Limited Access as of 2026) - contextual bandit reinforcement learning for content ranking.
• Anomaly Detector - phased out; the old decision-support items no longer appear. Microsoft guided migration toward custom time-series models on Azure Machine Learning or Microsoft Foundry.

Domain 3: Implement Computer Vision Solutions (10-15%)

Azure AI Vision (formerly Computer Vision)

• Image Analysis 4.0 (built on Florence foundation model): captioning, dense captioning, OCR/Read, object detection, people detection, background removal, smart crops, image retrieval via multimodal embeddings.
• Read API / OCR 4.0 for printed + handwritten text.
• Face API with Limited Access (requires approved registration) for detection, verification, identification, grouping.
• Spatial Analysis (container-only workload) for people counting, social-distancing analytics.

Custom Vision

• Build custom classification (multi-class or multi-label) and object detection models with a small training set (~50+ images per tag).
• Export models to ONNX, TensorFlow, CoreML, Docker for edge deployment.
• Understand iterations and performance metrics (precision, recall, mAP).

Azure AI Video Indexer

• Extract insights from video (speakers, topics, OCR, faces, sentiment, keywords, labels).
• Use custom models for language, brands, people.
• Integrate via widget embedding or API-driven pipelines.

Domain 4: Implement Natural Language Processing (15-20%)

Azure AI Language (formerly Text Analytics + LUIS + QnA Maker)

• Prebuilt features: sentiment analysis, opinion mining, key phrase extraction, language detection, PII detection + redaction, Named Entity Recognition (NER), text summarization (extractive + abstractive), healthcare text analytics.
• Custom models: custom NER, custom text classification (single + multi label), Conversational Language Understanding (CLU) (the successor to LUIS), Custom Question Answering (successor to QnA Maker), orchestration workflow for chaining CLU + QA.

Azure AI Translator

• Text translation (100+ languages), document translation, custom translator for domain-specific glossaries, transliteration.

Azure AI Speech

• Speech-to-Text (STT): real-time, batch, fast transcription, custom speech models, pronunciation assessment.
• Text-to-Speech (TTS): neural voices, custom neural voice (Limited Access), SSML for prosody.
• Speech translation: speech-to-speech translation across 50+ languages.
• Speaker recognition (Limited Access) for voice biometric identification/verification.

Note: LUIS (portal) was retired on October 1, 2025, with limited authoring-via-REST extended to March 31, 2026. Any study guide mentioning LUIS as current content is out of date. Use Conversational Language Understanding (CLU) instead.

Domain 5: Implement Knowledge Mining and Information Extraction (15-20%)

Azure AI Search (formerly Azure Cognitive Search)

• Create indexes, indexers, data sources, skillsets for AI enrichment.
• Built-in cognitive skills: OCR, key phrase extraction, entity recognition, translation, image analysis.
• Custom skills: call Azure Functions or custom APIs from a skillset.
• Vector search: create vector fields, embed documents via Azure OpenAI text-embedding-3-large / text-embedding-ada-002, perform hybrid search (keyword + vector), use semantic ranker for reranking.
• Integrated vectorization (GA 2024-2025): one-step index creation with automatic embedding via Azure OpenAI.
• Security trimming using user group membership or Entra ID.

Azure AI Document Intelligence (formerly Form Recognizer)

• Prebuilt models: invoices, receipts, ID documents, business cards, W-2s, 1098s, 1099s, health insurance cards, US/UK bank checks, pay stubs, contracts.
• Layout model for tables + structure.
• Custom models: custom template (form-based with fixed layout) vs custom neural (variable layout, signature detection, checkboxes).
• Composed models to route documents through multiple custom models.
• Train with as few as 5 labeled samples (template) or ~100+ samples (neural).

Domain 6: Implement Generative AI Solutions (15-20%) - The Highest-Value Chapter

This is the hottest and most-tested area of AI-102 in 2026, and its official weight rose to 15-20% in the final December 23, 2025 outline. Generative AI concepts also bleed into Domains 1 (responsible AI, content filtering, deployment types), 2 (agents), and 5 (RAG with Azure AI Search).

Azure OpenAI Service

• Provision and deploy models: GPT-4o, GPT-4o mini, GPT-4 Turbo, GPT-3.5 Turbo, o1 / o3-mini reasoning models, embeddings (text-embedding-3-large, text-embedding-3-small, ada-002), DALL-E 3, Sora (video - Limited Access), Whisper (speech-to-text).
• Choose a deployment type: Standard, Global Standard (lowest latency across regions), Provisioned Managed (PTU - reserved capacity), Global Batch (24-hour async jobs at 50% cost).
• Apply content filtering (hate, sexual, violence, self-harm with severity thresholds, plus prompt shields and protected material detection).
• Integrate via Azure OpenAI SDK (Python, C#, Java, JavaScript) or REST; use Entra ID with Managed Identity for keyless authentication.

Prompt engineering

• System messages for role priming, grounding, few-shot examples.
• Parameter tuning: temperature (0-2), top_p, presence_penalty, frequency_penalty, max_tokens, stop sequences, seed (for deterministic replays).
• Chain-of-thought (CoT) and reasoning prompts (especially for o1/o3 models).
• Function / tool calling: JSON schema definitions, tool choice, parallel calls.
• Structured outputs via JSON mode or strict JSON schema.

Retrieval-Augmented Generation (RAG)

• End-to-end pattern: chunk documents -> embed -> index in Azure AI Search -> retrieve with hybrid search + semantic ranker -> pass top-K chunks into a grounded prompt -> generate response with citations.
• "Add your data" (on your data) feature in Microsoft Foundry to wire RAG with a few clicks against Azure AI Search, Azure Blob, Azure Cosmos DB, URL, or Microsoft Fabric OneLake.
• Chunking strategies: fixed size, sentence-based, semantic chunking.
• Evaluation: groundedness, relevance, coherence, fluency metrics; prompt flow evaluation in Microsoft Foundry.

Microsoft Foundry (formerly Azure AI Studio / Azure AI Foundry)

• Create hubs and projects for AI development teams.
• Use the model catalog (Azure OpenAI + Meta Llama + Mistral + Cohere + custom) with serverless API deployments.
• Build agents with the Azure AI Agent Service (function calling + tool integration + code interpreter + file search + Bing grounding).
• Build prompt flows (visual DAG for prompt orchestration with evaluation + deployment).
• Monitor with AI-assisted metrics and safety evaluators.

Fine-tuning

• Supervised fine-tuning (SFT), DPO (direct preference optimization), continuous fine-tuning on GPT-4o, GPT-4o mini, GPT-3.5 Turbo, o4-mini (when available).
• Data format: JSONL with messages arrays.
• Evaluate vs base model, deploy as dedicated model.

Azure OpenAI Quick Reference (High-Yield for 2026)

Languages and SDKs on the Exam

AI-102 is an SDK-heavy exam. You will see code read and code-fill items in:

• Python (azure-ai-textanalytics, azure-ai-vision-imageanalysis, azure-ai-documentintelligence, openai (Azure OpenAI), azure-search-documents, azure-ai-language-conversations, azure-ai-ml).
• C# / .NET (Azure.AI.OpenAI, Azure.AI.Vision.ImageAnalysis, Azure.AI.Language, Azure.AI.DocumentIntelligence, Azure.Search.Documents).

You do not need to write code on a blank screen. You need to recognize the correct SDK call, parameter, or authentication pattern among multiple choices.

Example Code Snippet (Azure OpenAI - Python)

from openai import AzureOpenAI
from azure.identity import DefaultAzureCredential, get_bearer_token_provider

token_provider = get_bearer_token_provider(
    DefaultAzureCredential(),
    "https://cognitiveservices.azure.com/.default",
)

client = AzureOpenAI(
    azure_endpoint="https://my-aoai.openai.azure.com/",
    api_version="2024-10-21",
    azure_ad_token_provider=token_provider,
)

response = client.chat.completions.create(
    model="gpt-4o",  # deployment name
    temperature=0.2,
    response_format={"type": "json_object"},
    messages=[
        {"role": "system", "content": "Return strictly valid JSON."},
        {"role": "user", "content": "Extract invoice fields from: ..."},
    ],
)

Example Code Snippet (Azure AI Search - Hybrid Vector Query, Python)

from azure.search.documents import SearchClient
from azure.search.documents.models import VectorizedQuery

vector_query = VectorizedQuery(
    vector=embedding,  # 3072-dim from text-embedding-3-large
    k_nearest_neighbors=10,
    fields="content_vector",
)

results = search_client.search(
    search_text="privacy policy for minors",
    vector_queries=[vector_query],
    query_type="semantic",
    semantic_configuration_name="default",
    top=5,
)

8-Week AI-102 Study Plan (Working Developer)

This plan assumes ~8-10 hours per week and that you already know Python or C# plus basic Azure.

Recommended AI-102 Resources (FREE-First)

Hands-On Labs Are Non-Negotiable

AI-102 is not a memorization exam. Microsoft has moved aggressively toward case-study and performance-based items. Candidates who only watch videos routinely fail. Use the Azure free tier ($200 credit + 12 months of limited free services) or your employer's subscription to build:

1. An Azure OpenAI chat app with Entra ID auth, content filters, function calling, and structured JSON outputs.
2. An Azure AI Search index populated via integrated vectorization from a Blob container of 100+ PDFs.
3. A RAG app using Microsoft Foundry's "on your data" wired to that search index, with prompt flow evaluation for groundedness.
4. A Document Intelligence custom neural model trained on mixed-layout invoices, composed with a prebuilt receipt model.
5. A Custom Vision object detection model exported to ONNX.
6. An Azure AI Language CLU + Custom Question Answering orchestration bot deployed to a web app.
7. A Speech translation app using the Speech SDK with a custom neural voice for TTS output.

If you have built all seven, you will recognize every SDK call on the exam.

Common Pitfalls That Sink First-Time Scores

1. Studying an old (pre-2024) outline. Guides that still focus on LUIS, QnA Maker (old), Anomaly Detector as first-class, or skip Azure OpenAI entirely are out of date. Confirm the outline on learn.microsoft.com within 2 weeks of your exam.
2. Under-studying Azure OpenAI. With the final outline weight of 15-20% for generative AI plus its overlap into Domains 1 (responsible AI, content filtering), 2 (agents), and 5 (RAG), budget at least 25% of study time here.
3. Skipping Azure AI Search vector + hybrid + semantic. Integrated vectorization, text-embedding-3-large, hybrid queries, and semantic ranker configuration are high-yield in Domain 5.
4. Confusing custom template vs custom neural in Document Intelligence. Template = fixed layout, ~5 samples. Neural = variable layout, ~100 samples, supports signatures and selection marks. Exam items pick the cheaper/faster option when the layout allows.
5. Missing Entra ID / Managed Identity auth. Key-based auth is still valid but Microsoft's exam philosophy rewards Managed Identity + Entra ID + Key Vault for production readiness.
6. Ignoring Limited Access registrations. Face (verification/identification), Custom Neural Voice, Speaker Recognition, Personalizer require Microsoft approval. Items test whether you know the registration requirement.
7. Case study time management. Case studies embed 2-4 pages of context plus 4-6 linked questions. Read the question first, skim the case for the specific detail; do not re-read the entire case twice.
8. Weak on PTU vs Standard vs Global Standard vs Global Batch. Cost/latency/capacity trade-offs appear in every real exam report. Know when each deployment type wins.
9. Not knowing content filter tiers and Prompt Shield. Default low-severity blocking, customer-configurable severity, Prompt Shield vs Protected Material vs Groundedness. Easy points if memorized.
10. No timed full-length practice. 100 minutes across 40-60 items including case studies is tight; two timed mocks minimum before test day.

Test-Day Logistics and Strategies

Before you sit:

• Confirm your Microsoft Learn Profile matches your government ID exactly.
• If online-proctored, run the OnVUE system check 24 hours ahead; a single camera/mic issue can cost your slot.
• Clear your desk. Proctors will ask for a 360-degree room scan.

During the exam:

• You can flag and review within a section, but cannot return to prior sections once submitted.
• Case studies appear as standalone sections. Read the question first, skim the case for the relevant detail.
• When two answers look defensible, pick the Microsoft-native, managed-service option with least operational overhead (e.g., integrated vectorization beats hand-rolled embedding code; Managed Identity beats rotating keys).
• Target ~2 minutes per standalone item, ~4-5 minutes per case-study item.

After the exam:

• Pass/fail and scaled score (0-1000, pass = 700) displayed immediately.
• Skill-area breakdown emailed within 1-3 business days.
• If you fail: 24-hour wait for first retake, then 14-day wait for attempts 2-5, max 5 per 12 months.

Career Impact and Salary (Azure AI Engineer, 2026)

The AI engineering labor market is one of the tightest in tech. Microsoft-stack AI engineers with hands-on Azure OpenAI and RAG experience command a strong premium in 2026.

Azure AI Career Ladder

Deep Dives on Five Topics Competitor Guides Skim

1. Azure OpenAI Deployment Types (Standard vs PTU vs Global)

Azure OpenAI offers four deployment tiers in 2026, and knowing when each wins is the single highest-yield Domain 1 / Domain 6 cross-over concept.

• Standard (regional): pay-per-token, shared regional capacity, rate-limited by TPM (tokens per minute) and RPM (requests per minute). Good for dev/test and bursty small apps.
• Global Standard: pay-per-token at the same rate as Standard, but Microsoft routes to any region with capacity. Lowest latency for most workloads; the default recommendation for production apps without strict data residency.
• Provisioned Managed (PTU): reserve throughput in PTUs (each PTU = a fixed slice of per-minute capacity); predictable latency, no rate limiting, higher base cost but lower per-token effective rate at high utilization. Good for SLA-bound production apps.
• Global Batch: async file-based jobs, 50% discount, 24-hour SLA. Ideal for document summarization backfills, embedding generation jobs, data labeling.

2. Retrieval-Augmented Generation (RAG) End-to-End

RAG is the highest-impact generative pattern on AI-102. The canonical pipeline:

1. Ingest documents into Azure Blob, Cosmos DB, Fabric OneLake, or SharePoint.
2. Chunk using fixed size (512-1024 tokens) or semantic chunking. Overlap 10-20%.
3. Embed each chunk with text-embedding-3-large (3072 dims) or text-embedding-3-small (1536 dims). Integrated vectorization does this automatically.
4. Index in Azure AI Search with keyword + vector + semantic fields.
5. Retrieve top-K (typically 5-10) via hybrid query (BM25 + vector + semantic ranker).
6. Compose a grounded prompt with retrieved chunks as context and explicit citation instructions.
7. Generate with GPT-4o / GPT-4o mini.
8. Evaluate groundedness, relevance, coherence, fluency via prompt flow metrics.

Microsoft Foundry's "on your data" feature wires steps 4-7 automatically when pointed at an AI Search index, Blob container, Cosmos DB account, URL, or Fabric OneLake.

3. Content Filtering, Prompt Shields, and Groundedness

Azure OpenAI ships four families of safety checks:

• Content filters across hate, sexual, violence, self-harm with severity 0/2/4/6; blocked at low severity by default. Customer-configured filters (adjusting thresholds) require application approval.
• Prompt Shield - detects user-injected jailbreaks and indirect prompt injection within retrieved documents (RAG context).
• Protected Material detection - flags generation of copyrighted song lyrics/book text (text) or GitHub-sourced code (code).
• Groundedness detection - verifies whether a response is supported by provided sources, with per-sentence citations.

Azure AI Content Safety is the standalone service that exposes these capabilities plus image moderation and custom category models.

4. Microsoft Foundry, Agents, and Prompt Flow

Microsoft Foundry (rebranded from Azure AI Studio, then Azure AI Foundry) is the unified workspace for AI development:

• Hubs organize security, networking, and shared resources at the team/org level.
• Projects are the unit of AI development (prompt flows, evaluations, agents, deployments).
• Model catalog exposes Azure OpenAI, Meta Llama, Mistral, Cohere, Phi, and custom registered models with one-click serverless or managed deployment.
• Prompt flow is a visual DAG-based tool for prompt orchestration, evaluation, and deployment. Nodes call LLMs, Python scripts, Azure AI Search, etc.
• Azure AI Agent Service provides managed agents with function calling, code interpreter, file search, and Bing grounding - the successor to Assistants API with enterprise security.

5. Fine-Tuning vs Prompt Engineering vs RAG

Candidates frequently over-apply fine-tuning. The exam rewards picking the right tool:

• Prompt engineering (system prompts + few-shot) solves the vast majority of behavior shaping. Free and instant to iterate.
• RAG solves knowledge freshness and grounding - the model cites recent proprietary data it was never trained on.
• Fine-tuning solves style, tone, structure, and token efficiency - when you need a compressed instruction footprint or a specific output format. Use SFT or DPO on GPT-4o mini / GPT-3.5 Turbo / GPT-4o. Requires high-quality JSONL training data.

The canonical exam answer to "how should I reduce hallucinations about our internal HR policies" is RAG, not fine-tuning. "How should I enforce a strict company-specific JSON schema output" can go either way but often starts with structured outputs + prompt engineering before fine-tuning.

How AI-102 Fits into the Broader Microsoft AI / Data Certification Path

AI-102 pairs especially well with DP-100 (custom ML on Azure ML) and DP-700 (Fabric + AI Skill) for a full Microsoft-stack AI practitioner profile.

Renewal and Continuing Competency

Like all Microsoft role-based certifications, the Azure AI Engineer Associate is valid for one year. Renewal is FREE via Microsoft Learn - a browser-based assessment opens 6 months before expiration. It is typically 25-35 questions covering what has changed in the Azure AI surface area (new Azure OpenAI models, Foundry features, Content Safety capabilities, AI Search features) since your initial pass. There is no proctoring; you can retake renewals unlimited times.

Do not let it lapse. An expired credential cannot be renewed; because AI-102 is now retired (June 30, 2026), lapsed holders must pass the new AI-103 exam ($165) to re-earn an Azure AI credential. Given Azure AI's velocity of change, renewal is genuine continuing education - plan ~4-6 hours before the renewal assessment to review Microsoft Learn's "What's changed" guidance for Azure AI Engineer Associate.

Total Cost of AI-102 Certification (2026)

Azure Free Tier Strategy for AI-102 Labs

Azure's free tier is generous but has gotchas for AI workloads:

• Azure AI services (F0 tier) - free monthly quotas for Text Analytics, Vision, Language, Translator, Speech. Sufficient for most AI-102 labs.
• Azure OpenAI - no always-free tier. Use the $200 Azure credit for the first 30 days, then pay-as-you-go. Budget ~$5-$20 for GPT-4o mini experimentation across the full study period; GPT-4o full is more expensive, save for final integration labs.
• Azure AI Search - free tier (50 MB index, 3 replicas, 3 partitions) supports small RAG labs. Upgrade to Basic ($75/month) only if you need vector > 50 MB; you can also delete/recreate free-tier services between labs.
• Document Intelligence F0 - 500 pages/month free on prebuilt; custom models require S0 (paid).
• Content Safety F0 - 5K transactions/month free.
• Application Insights - free tier is ample for monitoring labs.

Rule of thumb: plan for $30-$100 of total Azure spend across the 8-week study period if you use GPT-4o mini and free tiers aggressively.
