Full question →mediummultiple choiceObjective-mapped
A customer support team receives thousands of unstructured chat transcripts every day. They want to automatically identify the most common recurring issues (e.g., 'long wait time', 'payment error', 'login problem') without training a custom model. Which prebuilt Azure AI Language feature should they use?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Key phrase extraction
Key phrase extraction identifies the most important words and phrases in the text, making it ideal for surfacing common issues from chat transcripts.
B
Distractor review
Named entity recognition (NER)
NER extracts predefined entity types like person, organization, location, but not general recurring topics or phrases.
C
Distractor review
Sentiment analysis
Sentiment analysis evaluates the polarity of the text (positive/negative/neutral), not the specific issues mentioned.
D
Distractor review
Language detection
Language detection identifies the language of the text, which is irrelevant to extracting recurring issues.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

The developer wants the model's responses to be maximally deterministic and factual, avoiding any creative or speculative language. Which parameter should the developer set to the lowest possible value in the API call?

FAQ
Questions learners often ask
What does this AI-900 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Key phrase extraction — Key phrase extraction is specifically designed to identify the main talking points or important topics in a text, such as recurring issues in chat transcripts. Named entity recognition (B) extracts specific entities like people, organizations, or locations, not general key concepts. Sentiment analysis (C) determines the emotional tone (positive, negative, neutral). Language detection (D) identifies the language of the text. None of these directly extract the common issues or topics as key phrases do.
