AI-102 Plan and manage an Azure AI solution Practice Question
Which TWO Azure AI services can you use to implement a custom question-answering system?
⚠ Common exam trap
Many exam-takers confuse Azure AI Search (a retrieval service) with a full question-answering system, forgetting that it only returns raw documents or passages and does not generate natural language answers, which requires a language model like Azure OpenAI Service or the custom question-answering feature in Azure AI Language.

Correct answer & explanation
✓
Azure OpenAI Service
Azure OpenAI Service is correct because it provides access to GPT models that can be fine-tuned or used with custom prompts to build a question-answering system. By leveraging the 'chat completions' API with a system message and context documents, you can implement a custom Q&A system that generates answers based on your proprietary data.

Variation 1. A company needs to implement a chatbot that answers customer queries using a knowledge base. Which Azure AI service should be used to build the knowledge base?
easy- ✓ A.Azure AI Language (Question Answering)
- B.Azure Bot Service
- C.Azure AI Translator
- D.Azure AI Speech
Why A: Azure AI Language's Question Answering feature is specifically designed to create a knowledge base from structured or unstructured content (e.g., FAQs, product manuals, support documents). It uses a custom question-answering model that can be trained and published as a REST API endpoint, which a chatbot can then query to retrieve precise answers. This makes it the correct service for building the knowledge base itself.
