AI-900Domain 4: Describe Features of Natural Language Processing Workloads on AzureNLP & SpeechmediumSingle choice
A company wants an FAQ bot that answers employee questions by matching them to its existing FAQ documents and URLs. Which feature fits?
A.Conversational language understanding
CLU extracts intents for task execution — not FAQ matching.
B.Question answering in Azure AI Language
KB-based question→answer matching. Correct.
C.Azure AI Search alone
AI Search could index FAQs but the purpose-built Q&A feature is the exam answer.
D.Speech-to-text
Speech is audio input — orthogonal.
Why this answer
Question answering creates a knowledge base from FAQs/documents/URLs and matches user questions to answers — the direct FAQ-bot feature (successor to QnA Maker). CLU is for task intents, not information retrieval.
