AI-102 Plan and manage an Azure AI solution Practice Question
This AI-102 practice question tests your understanding of plan and manage an azure ai solution. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
Clue confirmation
The clue word "first" in the question point toward this answer.

Common exam traps
Common exam trap: answer the scenario, not the keyword
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.
Detailed technical explanation
How to think about this question
QnA Maker uses a ranker that computes a confidence score based on term frequency, inverse document frequency (TF-IDF), and semantic similarity via a pre-trained model. When a user query has no close match in the alternative phrasings, the ranker may return a low-confidence answer or a completely unrelated one. In practice, adding 5–10 alternative phrasings per QnA pair, covering common synonyms and rewordings, can dramatically improve the match rate without any additional services.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
