Microsoft SC-401 Practice Test 46

Question 450

A connected third-party cloud app identified a publicly accessible file in storage. Which response most directly addresses the stated need?

  1. Investigate the available Insider Risk Management signals and alerts.
  2. Use Defender for Cloud Apps file-policy alert handling.
  3. Investigate the associated Purview DLP alert.
  4. Follow the Microsoft Defender XDR incident investigation workflow.

Explanation

Correct Answer

B:

Cloud Apps file-policy evidence describes matched connected-app files. It directly meets the case's requirement to investigate a third-party cloud file risk.

Incorrect Answers

A:

IRM correlates suspicious user activity patterns rather than only single DLP rule matches. That would evaluate an insider behavior pattern; the question instead requires a way to investigate a third-party cloud file risk.

C:

DLP alerts tie content-based policy actions to specific transfer attempts. That would investigate an Exchange DLP violation; the question instead requires a way to investigate a third-party cloud file risk.

D:

XDR incident correlation provides joined security-event context. That would investigate a cross-workload security incident; the question instead requires a way to investigate a third-party cloud file risk.

Question 451

Defender XDR aggregates endpoint, identity, and DLP signals into a potential cross-service attack. Which configuration BEST meets the requirement?

  1. Use Defender for Cloud Apps file-policy alert handling.
  2. Investigate the associated Purview DLP alert.
  3. Follow the Microsoft Defender XDR incident investigation workflow.
  4. Investigate the available Insider Risk Management signals and alerts.

Explanation

Correct Answer

C:

XDR incident correlation provides joined security-event context. It directly meets the case's requirement to investigate a cross-workload security incident.

Incorrect Answers

A:

Cloud Apps file-policy evidence describes matched connected-app files. That would investigate a third-party cloud file risk; the question instead requires a way to investigate a cross-workload security incident.

B:

IRM correlates suspicious user activity patterns rather than only single DLP rule matches. That would evaluate an insider behavior pattern; the question instead requires a way to investigate a cross-workload security incident.

Question 452

An auditor must review labeling changes but not read the body of every employee's file. Which Microsoft Purview approach should the administrator choose?

  1. Prepare scoped evidence and incident documentation from the authorized case.
  2. Use Content explorer or appropriately scoped eDiscovery content access.
  3. Require an authorized and appropriately scoped investigation before content search.
  4. Use Activity explorer or audit operation metadata with a least-privilege role.

Explanation

Correct Answer

D:

Activity records can explain actions without requiring full content access. It directly meets the case's requirement to audit labeling without broad content inspection.

Incorrect Answers

A:

Targeted evidence sharing minimizes unrelated personal data disclosure. That would provide only case-relevant evidence; the question instead requires a way to audit labeling without broad content inspection.

B:

Content review requires a separate authorized investigation path beyond aggregate audit data. That would inspect classified content under approval; the question instead requires a way to audit labeling without broad content inspection.

C:

Purview search capabilities are governed by roles and organizational privacy obligations. That would prevent indiscriminate employee content review; the question instead requires a way to audit labeling without broad content inspection.

Question 453

An authorized investigator must examine the actual body of a document that matched a SIT. Which action most directly satisfies this requirement?
