After working through 1008+ Azure AI-102 practice questions, the patterns are clear. The exam tests the same service selection decisions over and over, just with different wording. This guide gives you the shortcuts and elimination strategies to answer faster and more accurately.
The Keyword to Service Cheat Sheet When you see these words in a question, think the corresponding service: | Keyword in Question | Service to Think | |
|
| | Invoice, receipt, form fields | Document Intelligence | | Enterprise data, ground the model, RAG | Azure AI Search + RAG | | "Without keys", "managed identity" | Managed Identity + RBAC | | "Private network", "no internet" | Private Endpoints + VNet | | SQL injection, XSS, rate limiting | WAF | | DDoS, volumetric attack | Shield | | Sentiment, PII, key phrases, NER | Azure AI Language | | Speech-to-text, text-to-speech, wake word | Azure AI Speech | | Translate with custom terms | Custom Translator | | Image tags, captions, OCR on images | Azure AI Vision | | Harmful content, moderate text | Content Safety | | Jailbreak, prompt injection | Prompt Shields | | "Multiple models", routing | Microsoft Foundry / Orchestration | | Grounded prompt, prevent hallucinations | RAG + grounded prompt with refusal |
Elimination Strategies When two answers both seem right: 1. Pick the more managed service. The exam favors serverless, managed options over custom code or infrastructure. Cloud Run over GKE. Azure AI services over training your own model. 2. Pick the more specific service. If one answer is a general-purpose tool and another is purpose-built for the scenario, the purpose-built tool is usually correct. Document Intelligence is purpose-built for form extraction. Azure AI Vision does OCR but not structured field extraction from forms. 3. Pick the answer with the right security level. If the scenario mentions anything about production, sensitive data, or compliance, the answer must include managed identity + RBAC. Not API keys. 4. Pick the simpler architecture. If one answer requires building a custom pipeline and another uses a managed service that does the same thing, the managed service wins.
The 5 Most Tested Scenarios ### Scenario 1: RAG vs Fine-tuning Question pattern: "The model doesn't know about our company's products" or "The model fabricates details." Answer: RAG (ground with Azure AI Search), not fine-tuning. Fine-tuning changes behavior, RAG adds knowledge. ### Scenario 2: Private Endpoint Pattern Question pattern: Any mention of private network, no public internet, VNet only, or internal access only. Answer: Always includes private endpoints + managed identity. Never includes NAT gateways or public IPs. ### Scenario 3: Layer 7 Security Question pattern: Web app needs protection from OWASP attacks, SQL injection, XSS. Answer: WAF (Web Application Filter). Not Shield (DDoS), not Content Safety (text moderation). ### Scenario 4: Language vs Speech vs Translator Question pattern: Spoken word, wake phrase, speech output = Speech. Sentiment, PII, entity extraction = Language. Document/domain translation = Translator. ### Scenario 5: Agent vs Simple RAG Question pattern: Multi-step workflow, calls tools, takes actions = Agent. Questions from documents = RAG chatbot.
Quick Trap Reference 1. Increasing temperature makes output MORE random, not less 2. Multi-service resource = one endpoint for multiple AI services 3. Content Safety is NOT Azure AI Language (different problems) 4. Document Intelligence is NOT generic OCR (specific field extraction) 5. 429 errors = throttle, add retry/backoff, not add Key Vault 6. Prompt shields protect against jailbreaks, not object detection 7. Spatial analysis for people movement, not Document Intelligence 8. Image classification (no boxes) vs object detection (bounding boxes) 9. Custom Translator for domain terms, not standard Translator 10. Managed identity avoids keys, doesn't just reduce their scope
