AI-102 Plan and manage an Azure AI solution Practice Question
Your chatbot uses Azure Bot Service and QnA Maker. Users can ask questions in natural language, and the bot returns answers from a knowledge base. Users report that the bot sometimes returns irrelevant answers. What should you do first?
⚠ Common exam trap
The trap here is that candidates often jump to integrating LUIS or Azure AI Search as a 'smart' fix, but the exam expects you to first optimize the existing QnA Maker knowledge base by enriching it with alternative phrasings, which is the simplest and most direct solution for irrelevant answers.

Correct answer & explanation
✓
Review and edit the QnA pairs to add alternative phrasings
The core issue is that the bot returns irrelevant answers because the QnA Maker knowledge base lacks sufficient alternative phrasings to match the variety of user questions. By reviewing and editing QnA pairs to add alternative phrasings, you directly improve the synonym and paraphrase coverage, which increases the confidence score for correct matches and reduces irrelevant responses. This is the first and most fundamental troubleshooting step before considering more complex integrations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create multiple QnA Maker knowledge bases for different topics
Why it's wrong here
Splitting knowledge bases may not improve relevance; it adds complexity.
- ✗
Integrate LUIS to detect user intent
Why it's wrong here
LUIS helps with intent but does not improve answer relevance from a single KB.
- ✗
Use Azure AI Search to index the knowledge base
Why it's wrong here
QnA Maker already uses search; reindexing may not help without content improvement.
- ✓
Review and edit the QnA pairs to add alternative phrasings
Why this is correct
Adding more variations helps match user queries more accurately.
