Microsoft AI-103 Cheat Sheet: Apps and Agents

Review the Microsoft Azure AI Apps and Agents Developer Associate (AI-103) scope, Azure AI decision points, common traps, and practice strategy before using IT Mastery.

Use this cheat sheet to tighten the decisions AI-103 usually turns into scenario questions: when to use Microsoft Foundry, how to ground generative AI answers, where agent tools fit, and how to keep Azure AI solutions observable and controlled.

Use this with practice. Review the distinctions below, then try the free diagnostic or open the full AI-103 route in IT Mastery.

Must-know distinctions

DistinctionHow to decide
Foundry project vs app codeUse the project for model, deployment, evaluation, and governance configuration; use app code for product-specific workflow and integration.
Prompt-only vs grounded answerGround when answers must use private, current, or cited enterprise content.
Retrieval vs tool callRetrieval brings knowledge into context; tool calls execute actions or query external systems.
Agent vs simple chatUse an agent when the scenario needs multi-step reasoning, tools, instructions, or managed context.
Content safety vs evaluationContent safety blocks or moderates unsafe output; evaluation measures quality, grounding, and reliability.
OCR vs document intelligenceOCR reads text; document intelligence extracts structured fields and layout-aware values.
Entity extraction vs summarizationExtraction identifies structured facts; summarization compresses source content.
Managed identity vs key-based accessPrefer managed identity when Azure resources need secure service-to-service access without stored secrets.

High-yield checklist

  • Identify the workload first: generative AI, agentic workflow, vision, text analysis, speech, or document extraction.
  • Confirm whether the scenario needs private enterprise grounding, citations, or source filtering.
  • Keep model deployment, evaluation, monitoring, and responsible AI controls visible in implementation questions.
  • Use Azure AI Search or another retrieval layer when current source content must drive answers.
  • Push security decisions into identity, RBAC, managed identity, Key Vault, private networking, and data-access boundaries.
  • Watch for scenarios where a prebuilt service is better than custom model training.
  • For agents, separate instructions, tool definitions, data access, permissions, and human approval.
  • For extraction, check confidence thresholds, validation, exception handling, and downstream system integration.
  • For multimodal cases, confirm the input type before choosing a service.
  • For production readiness, look for telemetry, evaluation, rollback, and governance signals.

Common traps

  • Picking a general model when the task is really document extraction or language analysis.
  • Adding more prompt instructions instead of fixing grounding, retrieval, filtering, or evaluation.
  • Treating citations as optional when the scenario requires traceable enterprise answers.
  • Ignoring identity and data isolation in multi-tenant or regulated workloads.
  • Confusing model quality evaluation with content-safety enforcement.
  • Choosing custom training before checking whether a prebuilt Azure AI service meets the requirement.
  • Missing the difference between output generation and source-of-truth retrieval.

Practice strategy

Start with the free AI-103 diagnostic to see which domain creates the most misses. If generative AI and agent questions dominate the misses, drill grounding, tools, evaluation, and safety before returning to mixed practice. If service-selection questions dominate, work through the vision, text analysis, and information-extraction topic pages until the input/output pattern is automatic.

When you are scoring consistently above your target on unseen mixed attempts and can explain why the best answer fits the service boundary, security requirement, and operational constraint, move from topic drills to timed mocks.
