Developing AI Apps and Agents on Azure (AI-103) — Preguntas de práctica y simulacro de examen

Exam AI-103, Developing AI Apps and Agents on Azure, leads to the Microsoft Certified: Azure AI Apps and Agents Developer Associate certification. It is the successor to AI-102, which retires on 30 June 2026, and shifts the focus from wiring up pre-built Azure AI services to building generative AI applications and multi-agent solutions on Microsoft Foundry.

The exam targets Azure AI engineers who design, build, deploy, and operate AI apps and agents using Foundry, Azure OpenAI models, Azure AI Search, Azure AI Content Understanding, and the Azure AI Language, Vision, and Speech capabilities. You are expected to develop in Python and to understand generative AI patterns such as retrieval-augmented generation (RAG), tool calling, agent orchestration, and responsible AI.

Expect roughly 40 to 60 questions in about 120 minutes. Item types include single-answer multiple choice, multiple-response (select all that apply), and drag-and-drop ordering or mapping, with scenario-based stems that ask you to apply two or more concepts together. The score is reported on a 1 to 1000 scale and 700 is required to pass. AI-103 is a beta/early exam built on Microsoft Foundry, so questions emphasise generally available features and only cover preview features that are commonly used.

The most common trap is answering from older AI-102 knowledge. Multi-agent orchestration in the new Foundry Agent Service uses workflows, the Microsoft Agent Framework, and the agent-to-agent (A2A) tool — the classic Connected Agents tool is deprecated and is not part of the new service. Other frequent mistakes: reaching for fine-tuning when retrieval (RAG with Azure AI Search hybrid or vector search) is the grounded answer; putting API keys in config instead of using managed identity and keyless credentials; confusing Azure AI Document Intelligence with Azure AI Content Understanding for multimodal extraction; and forgetting responsible-AI instrumentation (content filters, safety evaluators, trace logging and provenance) that the exam explicitly tests.

The exam is delivered through Pearson VUE at a test center or as an online-proctored exam. A passing score is 700 on a 1 to 1000 scale. Microsoft associate certifications expire after one year and are renewed for free by passing a short online renewal assessment on Microsoft Learn. After a failed first attempt you must wait 24 hours before retaking; longer waits apply to subsequent attempts, with a limit of five attempts in a 12-month period.
