This MS-900 practice question tests your understanding of describe security, compliance, privacy, and trust in microsoft 365. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below.

You are configuring a Communication Compliance policy to detect workplace harassment. The policy currently includes conditions for sensitive information types (credit card numbers, SSN) and keywords. After deployment, the policy generates many irrelevant alerts for routine HR communications that contain the keywords but no harassment. What should you modify to improve detection accuracy?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a trainable classifier for 'harassment' instead of keyword matching
The policy should use a trainable classifier specifically for harassment (Option B) instead of broad sensitive info types and keywords. Sensitive info types (A) do not detect harassment. Option C (audit log is not relevant). Option D (expanding keywords would increase false positives).
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Enable audit logging for all communications
Why it's wrong here
Audit logging does not improve detection accuracy.

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.
