Administering Information Security in Microsoft 365 SC-401 Practice Test 31
Question 300
A compliance analyst needs to edit DLP policies but must not receive broad Global Administrator rights. After configuring the selected control, what acceptance evidence MOST DIRECTLY establishes that the stated boundary works?
- A DLP rule matches in simulation but no enforced transfer outcome was observed
- The policy has a restrictive display name but rule actions and workload scope were not verified
- The analyst edits an authorized pilot policy but cannot administer unrelated Entra tenant security
- An expected positive sample is detected, but a permitted negative sample was not tested
Explanation
Correct Answer
C:The analyst edits an authorized pilot policy but cannot administer unrelated Entra tenant security. This observation verifies the required control: Assign an appropriate scoped Microsoft Purview DLP administration role. Least-privilege Purview roles permit policy work without unrelated tenant-wide security privileges.
Incorrect Answers
A:Simulation can detect would-be matches without enforcing the block demanded by the scenario. In the present case the decisive acceptance evidence is: The analyst edits an authorized pilot policy but cannot administer unrelated Entra tenant security
B:A policy title provides no evidence of actual effective restriction. In the present case the decisive acceptance evidence is: The analyst edits an authorized pilot policy but cannot administer unrelated Entra tenant security
D:Positive-only detection does not establish exception handling or accurate policy scope. In the present case the decisive acceptance evidence is: The analyst edits an authorized pilot policy but cannot administer unrelated Entra tenant security
Question 301
A custom sensitive-information rule generates too many alerts when a single account-like string appears without context. Which Microsoft Purview configuration or security administration decision BEST meets the requirement?
- Block all file sharing regardless of content
- Tune the DLP sensitive-information type confidence and instance-count thresholds
- Increase only the DLP alert description font size
- Delete all Purview audit records after a match
Explanation
Correct Answer
B:Thresholds and evidence strength can reduce accidental matches without disabling target protection. This choice directly addresses the stated protected-data workflow.
Incorrect Answers
A:A universal block ignores the stated precision requirement and disrupts unrelated work. Consequently it cannot satisfy the stated requirement.
C:Alert display formatting cannot alter match accuracy. Consequently it cannot satisfy the stated requirement.
D:Deleting evidence neither improves matching nor supports investigations. Consequently it cannot satisfy the stated requirement.
Question 302
A custom sensitive-information rule generates too many alerts when a single account-like string appears without context. During the pilot, an administrator instead implements this approach: Block all file sharing regardless of content. The required outcome is not achieved. Which technical diagnosis BEST explains the failure?
- Alert display formatting cannot alter match accuracy
- Deleting evidence neither improves matching nor supports investigations
- Thresholds and evidence strength can reduce accidental matches without disabling target protection
- A universal block ignores the stated precision requirement and disrupts unrelated work
Explanation
Correct Answer
D:A universal block ignores the stated precision requirement and disrupts unrelated work. This identifies the failure of the specific pilot implementation.
Incorrect Answers
A:Alert display formatting cannot alter match accuracy. That limitation concerns a different competing approach, not this pilot change.
B:Deleting evidence neither improves matching nor supports investigations. This is a real constraint on a separate choice rather than the stated pilot implementation.
C:Thresholds and evidence strength can reduce accidental matches without disabling target protection. This describes the sound approach but does not diagnose why the observed alternative failed.
Question 303
A custom sensitive-information rule generates too many alerts when a single account-like string appears without context. A change reviewer proposes Increase only the DLP alert description font size instead of Tune the DLP sensitive-information type confidence and instance-count thresholds. Which assessment BEST explains the proposed design gap?
- Alert display formatting cannot alter match accuracy
- A universal block ignores the stated precision requirement and disrupts unrelated work
- Deleting evidence neither improves matching nor supports investigations
- Thresholds and evidence strength can reduce accidental matches without disabling target protection
Explanation
Correct Answer
A:Alert display formatting cannot alter match accuracy. This deficiency directly applies to the suggested competing design.
Incorrect Answers
B:A universal block ignores the stated precision requirement and disrupts unrelated work. This limitation relates to a different rejected configuration.
C:Deleting evidence neither improves matching nor supports investigations. This explains a different option rather than the actual proposal.
D:Thresholds and evidence strength can reduce accidental matches without disabling target protection. This supports the preferred design rather than evaluating the proposed alternative.
Question 304
A custom sensitive-information rule generates too many alerts when a single account-like string appears without context. After configuring the selected control, what acceptance evidence MOST DIRECTLY establishes that the stated boundary works?
- A DLP rule matches in simulation but no enforced transfer outcome was observed
- The policy has a restrictive display name but rule actions and workload scope were not verified
- Real positive samples match while short or low-confidence lookalikes stop triggering
- An expected positive sample is detected, but a permitted negative sample was not tested
Explanation
Correct Answer
C:Real positive samples match while short or low-confidence lookalikes stop triggering. This observation verifies the required control: Tune the DLP sensitive-information type confidence and instance-count thresholds. Thresholds and evidence strength can reduce accidental matches without disabling target protection.
Incorrect Answers
A:Simulation can detect would-be matches without enforcing the block demanded by the scenario. In the present case the decisive acceptance evidence is: Real positive samples match while short or low-confidence lookalikes stop triggering
B:A policy title provides no evidence of actual effective restriction. In the present case the decisive acceptance evidence is: Real positive samples match while short or low-confidence lookalikes stop triggering
D:Positive-only detection does not establish exception handling or accurate policy scope. In the present case the decisive acceptance evidence is: Real positive samples match while short or low-confidence lookalikes stop triggering
Question 305
A security operations center wants actionable DLP alerts for high-impact external sharing rather than a log entry for every harmless match. Which Microsoft Purview configuration or security administration decision BEST meets the requirement?
- Treat a policy tip visible to the sender as the SOC incident
- Set appropriate alert thresholds, severity and routing for relevant DLP policy matches
- Rely solely on retention label counts to detect exfiltration
- Disable activity auditing so analysts see fewer records
Explanation
Correct Answer
B:DLP alert configuration determines when matching activity becomes a triage item. This choice directly addresses the stated protected-data workflow.
Incorrect Answers
A:User guidance is not itself the managed SOC alert workflow. Consequently it cannot satisfy the stated requirement.
C:Retention inventory does not identify a specific external transfer event. Consequently it cannot satisfy the stated requirement.
D:Suppressing audit data reduces investigation evidence instead of tuning alerting. Consequently it cannot satisfy the stated requirement.

Question 308
A security operations center wants actionable DLP alerts for high-impact external sharing rather than a log entry for every harmless match. After configuring the selected control, what acceptance evidence MOST DIRECTLY establishes that the stated boundary works?
- A DLP rule matches in simulation but no enforced transfer outcome was observed
- The policy has a restrictive display name but rule actions and workload scope were not verified
- High-risk pilot transfer creates a triage alert with context; benign matched activities follow the intended route
- An expected positive sample is detected, but a permitted negative sample was not tested
Explanation

Question 309
A company uses Adaptive Protection to make DLP restrictions stricter for users at elevated insider-risk levels. Which Microsoft Purview configuration or security administration decision BEST meets the requirement?
- Create static DLP rules identical for every user and call them adaptive
- Change a file's retention label when user risk changes
- Configure Adaptive Protection risk levels and apply them to supported DLP rules
- Set all users to a permanent high-risk state without assessment
Explanation
Correct Answer
C:Adaptive Protection ties insider-risk signals to risk-based enforcement policy decisions. This choice directly addresses the stated protected-data workflow.
Incorrect Answers
A:Uniform rules cannot dynamically adapt to a user's changing risk state. Consequently it cannot satisfy the stated requirement.
B:Lifecycle labels do not automatically implement risk-sensitive egress actions. Consequently it cannot satisfy the stated requirement.
D:Blanket risk designation defeats the intended proportional control. Consequently it cannot satisfy the stated requirement.
