AI-102 Practice Question: Implement natural language processing solutions
A company is building a chatbot using Azure Cognitive Service for Language. They need to ensure that user utterances are correctly mapped to the appropriate intent in a custom question answering project. What should they configure?
⚠ Common exam trap
Candidates often confuse the role of synonyms/phrase lists in custom question answering with the separate LUIS service, or mistakenly think alternative question phrases (Option B) are the primary mechanism for intent mapping, when in fact they only expand answer triggers, not intent classification.

Correct answer & explanation
✓
Add synonyms and phrase list to the custom question answering project.
Adding synonyms and phrase lists to a custom question answering project directly improves the mapping of user utterances to intents by normalizing variations in phrasing. This configuration allows the project to recognize equivalent terms (e.g., 'cost' and 'price') as the same intent, ensuring accurate intent mapping without requiring exact matches.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Add synonyms and phrase list to the LUIS application.
Why it's wrong here
LUIS is not used in custom question answering; synonyms are configured directly in the knowledge base.
- ✗
Add alternative question phrases to the QnA pairs in the custom question answering project.
Why it's wrong here
While adding alternative questions is useful, the question specifically asks about synonyms and phrase lists, not alternative questions.
- ✗
Define entities in the custom question answering project to capture key information.
Why it's wrong here
Entities are used in LUIS and conversational language understanding, not in custom question answering.
- ✓
Add synonyms and phrase list to the custom question answering project.
Why this is correct
Synonyms and phrase lists help match varied user utterances to the correct QnA pair.
