Microsoft SC-401 Practice Test 43

Question 420

A classification officer wants to know which users recently downgraded a sensitivity label on supported files. Which response most directly addresses the stated need?

  1. Analyze applicable DLP activities in Activity explorer.
  2. Query the relevant administrative event through Purview Audit.
  3. Use a scoped eDiscovery content search and authorized review workflow.
  4. Filter Purview Activity explorer for relevant label-change activities.

Explanation

Correct Answer

D:

Activity explorer exposes supported protection-related user operations. It directly meets the case's requirement to investigate sensitivity label downgrades.

Incorrect Answers

A:

DLP activities provide operational trends and event details about detected data handling. That would inspect DLP policy activities; the question instead requires a way to investigate sensitivity label downgrades.

B:

Audit searches record supported control-plane changes, not just information-protection file operations. That would trace an audit policy administration event; the question instead requires a way to investigate sensitivity label downgrades.

C:

eDiscovery retrieves responsive content for case review. That would locate evidence files rather than access events; the question instead requires a way to investigate sensitivity label downgrades.

Question 421

A DLP owner wants to review policy matches for protected files sent to external locations. Which configuration BEST meets the requirement?

  1. Analyze applicable DLP activities in Activity explorer.

  2. Query the relevant administrative event through Purview Audit.
  3. Filter Purview Activity explorer for relevant label-change activities.
  4. Analyze applicable DLP activities in Activity explorer.

Question 423

A legal discovery specialist wants copies of matching files, not just telemetry about access. Which action most directly satisfies this requirement?

  1. Analyze applicable DLP activities in Activity explorer.
  2. Query the relevant administrative event through Purview Audit.
  3. Use a scoped eDiscovery content search and authorized review workflow.
  4. Filter Purview Activity explorer for relevant label-change activities.

Explanation

Correct Answer

Question 424

Legal needs to search Exchange mailboxes of two named custodians for a contract name and a specified date range. What is the most appropriate next action?

  1. Search the supported Endpoint DLP or audit activity events.
  2. Include the approved SharePoint site locations in the eDiscovery search scope.
  3. Constrain eDiscovery case data sources and reviewer permissions.

Explanation

Question 428

A Defender for Cloud Apps file policy detects a stored file shared publicly by mistake. Which action most directly satisfies this requirement?

  1. Review the corresponding Defender for Cloud Apps session activity and alert evidence.
  2. Review appropriate Purview DLP and SharePoint audit evidence.
  3. Inspect the alert's governance action result or related activity.
  4. Review the matching file-policy alert and supported file governance status.

Explanation

Correct Answer

D:

A Cloud Apps file alert identifies the affected cloud asset and configured policy. It directly meets the case's requirement to inspect public cloud-file sharing.
