Question 600
Security needs to diagnose why an onboarded laptop has stopped sending Defender telemetry. The team observes: The laptop shows no new detections only because the endpoint sensor is inactive. What root cause should be investigated first?
- The team never reviewed Defender endpoint software inventory and version evidence.
- Endpoint sensor health was not differentiated from a healthy no-threat state.
- Defender vulnerability recommendations and affected-asset evidence were not reviewed.
- Policy alert context was not linked to its underlying activity evidence.
Explanation
Correct Answer
B:Endpoint sensor health was not differentiated from a healthy no-threat state. That issue explains the observed symptom: The laptop shows no new detections only because the endpoint sensor is inactive. The relevant correction is: Inspect Defender device sensor status and applicable diagnostic connectivity logs.
Incorrect Answers
A:The team never reviewed Defender endpoint software inventory and version evidence. would fit a different circumstance involving: A tenant wants to reduce risky applications by understanding installed software on managed endpoints. Here the actual symptom is: The laptop shows no new detections only because the endpoint sensor is inactive.
C:Defender vulnerability recommendations and affected-asset evidence were not reviewed. is a plausible failure in another case: The team assumes patched devices are safe without reviewing the inventory's remaining vulnerabilities. It does not explain the current incident: The laptop shows no new detections only because the endpoint sensor is inactive.
D:Policy alert context was not linked to its underlying activity evidence. would fit a different circumstance involving: Investigators must differentiate cloud app file-sharing policy alerts from raw individual user activities. Here the actual symptom is: The laptop shows no new detections only because the endpoint sensor is inactive.
Question 601
Administrators want an endpoint attack-surface reduction rule to restrict risky behaviors. What design decision would best satisfy the stated constraint?
- Configure supported Microsoft Defender attack surface reduction policies in an eligible management channel.

Question 603
Administrators want an endpoint attack-surface reduction rule to restrict risky behaviors. Which observation provides the strongest evidence that the requirement was met?
- The device health view identifies the sensor or network communication problem.
- Endpoint policy reporting shows the selected ASR rule and observed enforcement.
- The specific affected devices and fixed-version recommendation are recorded.
- The team identifies both the policy condition and the user action that triggered it.
Explanation
Correct Answer
B:Endpoint policy reporting shows the selected ASR rule and observed enforcement. This directly checks the stated goal: Administrators want an endpoint attack-surface reduction rule to restrict risky behaviors. It distinguishes success from the reported failure mode: A risky process remains allowed because the ASR rule was left in audit-only mode.
Incorrect Answers
A:The device health view identifies the sensor or network communication problem. would assess a different control. In this case it does not rule out the specific failure: A risky process remains allowed because the ASR rule was left in audit-only mode.
C:The specific affected devices and fixed-version recommendation are recorded. is evidence of another system state: A CVE affects one outdated application installed on a subset of corporate laptops. The acceptance evidence here instead is: Endpoint policy reporting shows the selected ASR rule and observed enforcement.
D:The team identifies both the policy condition and the user action that triggered it. would assess a different control. In this case it does not rule out the specific failure: A risky process remains allowed because the ASR rule was left in audit-only mode.
Question 604
Administrators want an endpoint attack-surface reduction rule to restrict risky behaviors. The team observes: A risky process remains allowed because the ASR rule was left in audit-only mode. Which configuration mistake best explains this reported failure?

- A per-message false positive was handled as a tenant-wide policy override.
- The selected ASR rule was never put into an enforcement mode for the devices.
- Policy alert context was not linked to its underlying activity evidence.
Explanation
Correct Answer
C:The selected ASR rule was never put into an enforcement mode for the devices. That issue explains the observed symptom: A risky process remains allowed because the ASR rule was left in audit-only mode. The relevant correction is: Deploy the specific ASR rule with an approved mode to the appropriate device group.
Incorrect Answers
A:The onboarding deployment mechanism did not reach or enroll the servers. would fit a different circumstance involving: A large fleet of Windows servers needs consistent Defender endpoint onboarding without manual portal actions. Here the actual symptom is: A risky process remains allowed because the ASR rule was left in audit-only mode.
B:A per-message false positive was handled as a tenant-wide policy override. is a plausible failure in another case: Administrators disable phishing protections globally to release a single legitimate invoice. It does not explain the current incident: A risky process remains allowed because the ASR rule was left in audit-only mode.
D:Policy alert context was not linked to its underlying activity evidence. would fit a different circumstance involving: Investigators must differentiate cloud app file-sharing policy alerts from raw individual user activities. Here the actual symptom is: A risky process remains allowed because the ASR rule was left in audit-only mode.
