Microsoft AB-900 Practice Test 39

Question 380

An employee repeatedly violates DLP restrictions and investigators need escalation. Which Microsoft 365 capability is MOST appropriate?

  1. Use the DLP incident response process with relevant alerts and case assignment.
  2. Inspect the DLP alert and matched rule evidence.
  3. Use supported DLP test or simulation mode.
  4. Apply a reviewed DLP exception or permitted justification within policy.

Explanation

Correct Answer

A:

DLP monitoring supports accountable follow-up on repeated violations. This directly addresses repeated data-loss incident response.

Incorrect Answers

B:

Alert details identify the sensitive type, location and enforcement reason. The action is relevant to evidence for a sensitive outbound email block rather than repeated data-loss incident response.

C:

Simulated matches allow validation before production enforcement. This helps with impact testing of a new DLP rule instead of the required repeated data-loss incident response.

D:

Governed exceptions avoid weakening protection for all users. The action is relevant to narrowly authorized protected-data sharing rather than repeated data-loss incident response.

Question 381

The compliance office wants only designated investigators to view flagged private messages. Which approach solves the stated need?

  1. Record the review outcome and escalation in the Communication Compliance case workflow.
  2. Assign appropriately scoped Communication Compliance reviewer roles.
  3. Review the flagged communication in Purview Communication Compliance.
  4. Refine the Communication Compliance policy classification and conditions.

Explanation

Correct Answer

B:

A:

Review dispositions preserve a decision trail for policy violations. It is used for accountable escalation of flagged messages; this scenario calls for protected access to communications investigations.

C:

Communication Compliance surfaces supported risky messages to authorized reviewers. It is used for conduct-related Teams message review; this scenario calls for protected access to communications investigations.

D:

Narrower detection criteria can improve review precision. That addresses tuned employee communication policy, whereas the current case requires protected access to communications investigations.

Question 382

A prosecutor needs to collect a copy of particular emails under legal procedures. Which Microsoft 365 capability is MOST appropriate?

  1. Review appropriate AI/DLP rule-match activity events.
  2. Generate a SharePoint data access governance sharing links report.
  3. Use a supported eDiscovery case and targeted content search.
  4. Filter Purview Activity explorer by label activity.

Explanation

Correct Answer

C:

Case-based discovery locates responsive items and preserves review controls. This directly addresses formal litigation content collection.

Incorrect Answers

A:

AI activity telemetry includes supported rule-match events and metadata. It would support Copilot DLP trigger timeline, not the stated formal litigation content collection.

B:

Data access governance focuses site access exposure rather than classification actions. Its purpose is sites creating broad sharing links; the specified need is formal litigation content collection.

D:

Activity explorer records content classification actions over time. Its purpose is temporal label-usage evidence; the specified need is formal litigation content collection.

Question 383

Security wants to understand exactly which recorded prompts triggered a sensitive-data incident, where collection is enabled. Which approach solves the stated need?

C:

DLP provides enforcement evidence for supported AI content flows. The action is relevant to AI-specific data loss prevention rather than specific risky AI interaction evidence.

Question 384

The legal department wants to manage access and collection responsibilities for multiple distinct cases. Which Microsoft 365 capability is MOST appropriate?

  2. Create an eDiscovery case and run a scoped content search.
  3. Place the relevant custodial content on a supported eDiscovery hold.
  4. Search supported Copilot interaction records within eDiscovery.

Explanation

B:

Alert casework supports remediation beyond a simple block. The action is relevant to governed data incident follow-up rather than recurring regulatory assessment.

D:

Site owners can confirm needed access without security staff guessing business relationships. The action is relevant to owner-driven oversharing remediation rather than recurring regulatory assessment.

C:

Reviewers assess policy context and document their disposition. It would support conduct violation assessment, not the stated hold-compliant preservation.

D:

Insider risk contextualizes configured user behavior for triage. Its purpose is suspicious worker file-exfiltration investigation; the specified need is hold-compliant preservation.
