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

Microsoft 365 Audit Log

The unified audit log records all user and admin actions, including SharePoint file accesses and DLP actions, meeting forensic requirements.

B

Distractor review

Microsoft Defender for Cloud Apps

Defender for Cloud Apps provides visibility and control over app usage but does not log granular file-level access in SharePoint.

C

Distractor review

Microsoft Purview Activity Explorer

Activity Explorer focuses on DLP-related events, not all file access logs.

D

Distractor review

Microsoft 365 Defender

Microsoft 365 Defender is a suite of threat protection services, not a detailed audit logging solution.

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

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.

FAQ

Questions learners often ask

What does this MS-900 question test?

Read the scenario before looking for a memorised answer.

What is the correct answer to this question?

The correct answer is: Microsoft 365 Audit Log — The Microsoft 365 Unified Audit Log captures user and admin activities across services, including file access, DLP rule matches, and blocked attempts. It is the primary source for forensic investigations. Activity Explorer (in Purview DLP) shows DLP-related events but not all file access logs. Microsoft Defender for Cloud Apps provides app-level activity logs but does not replace the audit log for SharePoint file access. Microsoft 365 Defender is a broader security suite, not a detailed audit log.
