Microsoft SC-900 Practice Test 69

Question 680

At the Valeford municipal government, security responders cannot tell whether all company laptops have been onboarded to endpoint protection. How should the organization sustain the improvement?

  1. Tune anomaly thresholds and cloud connector coverage periodically
  2. Review firewall rule collections as internal services change
  3. Audit onboarding gaps after device procurement and retirement
  4. Review workspace configuration and access as SOC teams change

Explanation

Correct Answer

C:

The continuing safeguard is to audit onboarding gaps after device procurement and retirement. It helps avoid the original condition: an endpoint security plan only covers devices that are properly onboarded and sending required signals. This result addresses the stated challenge at the Valeford municipal government.

Incorrect Answers

A:

The option would have the team tune anomaly thresholds and cloud connector coverage periodically. For this situation, the preventive control should instead be to audit onboarding gaps after device procurement and retirement. For the Valeford municipal government, the direct corrective action is to review Microsoft Defender for Endpoint device inventory and onboarding status.

B:

Although the proposed practice may address cases where network rules support precise transport-level filtering instead of unrestricted connectivity, it does not maintain the specific correction here. For the Valeford municipal government, the direct corrective action is to review Microsoft Defender for Endpoint device inventory and onboarding status.

D:

The suggested review does not track the condition behind the incident. Sustained improvement requires the team to audit onboarding gaps after device procurement and retirement. For the Valeford municipal government, the direct corrective action is to review Microsoft Defender for Endpoint device inventory and onboarding status.

Question 681

At the Lakehaven retail company, an attacker executes suspicious endpoint processes but the SOC only checks installed antivirus signatures. Which approach best resolves the identified risk?

  1. Use Microsoft Defender for Endpoint endpoint detection and response telemetry for suspicious device behavior
  2. Use available Microsoft Threat Intelligence indicator and threat context in supported investigations
  3. Select appropriate Sentinel and Log Analytics ingestion and retention settings for approved investigation needs
  4. Use Sentinel entity and investigation context to connect related users hosts and other indicators

Explanation

Correct Answer

A:

The reported facts support this change rather than a general platform replacement. The team should use Microsoft Defender for Endpoint endpoint detection and response telemetry for suspicious device behavior because eDR investigates suspicious activity chains beyond simple signature-based malware scanning. A suitable test confirms that a safe test activity produces the intended endpoint detection and process evidence. This result addresses the stated challenge at the Lakehaven retail company.

Incorrect Answers

B:

The suggested action is to use available Microsoft Threat Intelligence indicator and threat context in supported investigations, but the facts at the Lakehaven retail company require a correction for the distinct problem that eDR investigates suspicious activity chains beyond simple signature-based malware scanning.

C:

This alternative would be suitable where log storage and ingestion choices affect cost and the period of evidence available to security investigators. It does not by itself resolve the need to use Microsoft Defender for Endpoint endpoint detection and response telemetry for suspicious device behavior. For the Lakehaven retail company, the direct corrective action is to use Microsoft Defender for Endpoint endpoint detection and response telemetry for suspicious device behavior.

D:

Use Sentinel entity and investigation context to connect related users hosts and other indicators addresses a different kind of problem: SIEM event correlation is more useful when related entities can be examined together. Here the reported weakness is that eDR investigates suspicious activity chains beyond simple signature-based malware scanning. For the Lakehaven retail company, the direct corrective action is to use Microsoft Defender for Endpoint endpoint detection and response telemetry for suspicious device behavior.

Question 682

At the Lakehaven retail company, an attacker executes suspicious endpoint processes but the SOC only checks installed antivirus signatures. Which explanation best accounts for the concern?

  1. Hybrid identity investigations are strengthened when on-premises directory alerts join cross-product incidents
  2. EDR investigates suspicious activity chains beyond simple signature-based malware scanning
  3. Inbound translation maps an approved external address and port to a protected internal endpoint
  4. Distributed denial-of-service attacks overwhelm availability at network scale and are distinct from ordinary authorized usage

Explanation

Correct Answer

B:

The problem stems from the fact that eDR investigates suspicious activity chains beyond simple signature-based malware scanning. A correct solution would use Microsoft Defender for Endpoint endpoint detection and response telemetry for suspicious device behavior and check that a safe test activity produces the intended endpoint detection and process evidence. This result addresses the stated challenge at the Lakehaven retail company.

Incorrect Answers

A:

The case does not describe the failure mode involving defender for identity hybrid correlation. Its core issue is that eDR investigates suspicious activity chains beyond simple signature-based malware scanning. For the Lakehaven retail company, the direct corrective action is to use Microsoft Defender for Endpoint endpoint detection and response telemetry for suspicious device behavior.

C:

This explanation belongs to a different security or compliance situation. In this case, the observable gap is that eDR investigates suspicious activity chains beyond simple signature-based malware scanning. For the Lakehaven retail company, the direct corrective action is to use Microsoft Defender for Endpoint endpoint detection and response telemetry for suspicious device behavior.

D:

Distributed denial-of-service attacks overwhelm availability at network scale and are distinct from ordinary authorized usage. That may occur elsewhere, but the evidence at the Lakehaven retail company instead points to the fact that eDR investigates suspicious activity chains beyond simple signature-based malware scanning.

Question 683

At the Lakehaven retail company, an attacker executes suspicious endpoint processes but the SOC only checks installed antivirus signatures. Which test result best shows the requirement is met?

  1. A controlled cross-workload case links its endpoint and identity events under an investigation
  2. A safe test activity produces the intended endpoint detection and process evidence
  3. An approved administrative source connects while an unknown source's management port test is blocked
  4. A posture review documents remaining risks despite an improved security score

Explanation

Correct Answer

B:

This is the relevant acceptance result: a safe test activity produces the intended endpoint detection and process evidence. It demonstrates the outcome of choosing to use Microsoft Defender for Endpoint endpoint detection and response telemetry for suspicious device behavior. This result addresses the stated challenge at the Lakehaven retail company.

Incorrect Answers

A:

This verifies a separate issue in security administration. It does not prove that a safe test activity produces the intended endpoint detection and process evidence for the reported situation. For the Lakehaven retail company, the direct corrective action is to use Microsoft Defender for Endpoint endpoint detection and response telemetry for suspicious device behavior.

C:

That observation may be useful for another security or compliance workflow, but the current acceptance test must demonstrate that a safe test activity produces the intended endpoint detection and process evidence. For the Lakehaven retail company, the direct corrective action is to use Microsoft Defender for Endpoint endpoint detection and response telemetry for suspicious device behavior.

D:

At the Lakehaven retail company, a result about secure score interpretation would not show that the team corrected the failure where eDR investigates suspicious activity chains beyond simple signature-based malware scanning.

Question 684

At the Lakehaven retail company, an attacker executes suspicious endpoint processes but the SOC only checks installed antivirus signatures. Which ongoing control best prevents this issue from recurring?

  1. Review EDR alerts and device health after agent updates
  2. Review ASR rule impact and false positives before enforcing broadly
  3. Maintain tested queries when source table schemas change
  4. Review network and web-layer threat coverage after workload exposure changes

Explanation

Correct Answer

A:

The continuing safeguard is to review EDR alerts and device health after agent updates. It helps avoid the original condition: eDR investigates suspicious activity chains beyond simple signature-based malware scanning. This result addresses the stated challenge at the Lakehaven retail company.

Incorrect Answers

B:

The suggested review does not track the condition behind the incident. Sustained improvement requires the team to review EDR alerts and device health after agent updates. For the Lakehaven retail company, the direct corrective action is to use Microsoft Defender for Endpoint endpoint detection and response telemetry for suspicious device behavior.

C:

Maintain tested queries when source table schemas change is not the primary recurring safeguard for this problem. The team should review EDR alerts and device health after agent updates. For the Lakehaven retail company, the direct corrective action is to use Microsoft Defender for Endpoint endpoint detection and response telemetry for suspicious device behavior.

D:

This is a maintenance action for a different security or compliance situation, rather than the one that originally failed because eDR investigates suspicious activity chains beyond simple signature-based malware scanning. For the Lakehaven retail company, the direct corrective action is to use Microsoft Defender for Endpoint endpoint detection and response telemetry for suspicious device behavior.

Question 685

At the Westwick telecommunications provider, a confirmed compromised workstation continues reaching internal resources during incident investigation. Which implementation choice best addresses the situation?

  1. Use Microsoft Defender for Endpoint endpoint detection and response telemetry for suspicious device behavior
  2. Use an authorized Defender for Endpoint device isolation response where supported
  3. Use an appropriately governed Microsoft Sentinel watchlist as enrichment context in KQL investigations
  4. Enable the appropriate Microsoft Defender for SQL protection for the database resource

Explanation

Correct Answer

B:

Use an authorized Defender for Endpoint device isolation response where supported is the best response because isolation can limit network communication from a suspected endpoint while responders investigate. A focused validation would establish that a safe test isolation blocks ordinary network access while maintaining the permitted management channel. This result addresses the stated challenge at the Westwick telecommunications provider.

Incorrect Answers

A:

This alternative would be suitable where eDR investigates suspicious activity chains beyond simple signature-based malware scanning. It does not by itself resolve the need to use an authorized Defender for Endpoint device isolation response where supported. For the Westwick telecommunications provider, the direct corrective action is to use an authorized Defender for Endpoint device isolation response where supported.

C:

The option addresses the separate situation where security monitoring can join event records with controlled reference lists for context. For this case, the more appropriate response is to use an authorized Defender for Endpoint device isolation response where supported. For the Westwick telecommunications provider, the direct corrective action is to use an authorized Defender for Endpoint device isolation response where supported.

D:

This focuses on defender for sql workload security; it does not directly correct the condition that isolation can limit network communication from a suspected endpoint while responders investigate. For the Westwick telecommunications provider, the direct corrective action is to use an authorized Defender for Endpoint device isolation response where supported.

Question 686

At the Westwick telecommunications provider, a confirmed compromised workstation continues reaching internal resources during incident investigation. What risk should the team identify as the primary issue?

  1. Isolation can limit network communication from a suspected endpoint while responders investigate
  2. Awareness exercises should measure behavior using controlled simulations rather than real credential theft
  3. Time-bounded management access can reduce the risk of always-open administrative ports
  4. A SIEM collects and correlates events to support threat detection across diverse sources

Explanation

Correct Answer

A:

The situation shows that isolation can limit network communication from a suspected endpoint while responders investigate, rather than merely a monitoring or presentation issue. Remediation is to use an authorized Defender for Endpoint device isolation response where supported. This result addresses the stated challenge at the Westwick telecommunications provider.

Incorrect Answers

B:

Awareness exercises should measure behavior using controlled simulations rather than real credential theft. That may occur elsewhere, but the evidence at the Westwick telecommunications provider instead points to the fact that isolation can limit network communication from a suspected endpoint while responders investigate.

C:

The proposed cause is relevant to just-in-time vm access, but it does not explain why isolation can limit network communication from a suspected endpoint while responders investigate in the reported case. For the Westwick telecommunications provider, the direct corrective action is to use an authorized Defender for Endpoint device isolation response where supported.

D:

A SIEM collects and correlates events to support threat detection across diverse sources. That is not the mechanism that accounts for the stated failure at the Westwick telecommunications provider.

Question 687

At the Westwick telecommunications provider, a confirmed compromised workstation continues reaching internal resources during incident investigation. What is the strongest acceptance test for this change?

  1. A safe test isolation blocks ordinary network access while maintaining the permitted management channel
  2. A sample incident has an assigned owner final classification and documented response evidence
  3. A posture review identifies the multi-resource exposure chain and verifies corrective controls break it
  4. An approved administrative source connects while an unknown source's management port test is blocked

Explanation

Correct Answer

A:

Because isolation can limit network communication from a suspected endpoint while responders investigate, the required evidence must show that a safe test isolation blocks ordinary network access while maintaining the permitted management channel. A green job status alone is insufficient. This result addresses the stated challenge at the Westwick telecommunications provider.

Incorrect Answers

B:

At the Westwick telecommunications provider, a result about defender portal evidence handoff would not show that the team corrected the failure where isolation can limit network communication from a suspected endpoint while responders investigate.

C:

The alternative checks whether a posture review identifies the multi-resource exposure chain and verifies corrective controls break it, which is not the direct acceptance criterion for the stated problem. The required result is that a safe test isolation blocks ordinary network access while maintaining the permitted management channel. For the Westwick telecommunications provider, the direct corrective action is to use an authorized Defender for Endpoint device isolation response where supported.

D:

This result would validate network security group inbound rules, not the intended improvement. The needed observation is that a safe test isolation blocks ordinary network access while maintaining the permitted management channel. For the Westwick telecommunications provider, the direct corrective action is to use an authorized Defender for Endpoint device isolation response where supported.

Question 688

At the Westwick telecommunications provider, a confirmed compromised workstation continues reaching internal resources during incident investigation. Which setting or practice should be reviewed in future?

  1. Review high-privilege app consent grants as third-party integrations expand
  2. Review critical log source ingestion and retention when new services are added
  3. Rehearse safe restoration and isolation approvals during incident exercises
  4. Monitor connector health and permission expiry after tenant updates

Explanation

Correct Answer

C:

The team should rehearse safe restoration and isolation approvals during incident exercises. That recurring practice targets the same weakness, namely that isolation can limit network communication from a suspected endpoint while responders investigate. This result addresses the stated challenge at the Westwick telecommunications provider.

Incorrect Answers

A:

Review high-privilege app consent grants as third-party integrations expand is not the primary recurring safeguard for this problem. The team should rehearse safe restoration and isolation approvals during incident exercises. For the Westwick telecommunications provider, the direct corrective action is to use an authorized Defender for Endpoint device isolation response where supported.

B:

This is a maintenance action for a different security or compliance situation, rather than the one that originally failed because isolation can limit network communication from a suspected endpoint while responders investigate. For the Westwick telecommunications provider, the direct corrective action is to use an authorized Defender for Endpoint device isolation response where supported.

D:

Although the proposed practice may address cases where a SIEM cannot correlate events that it has not been authorized and configured to ingest, it does not maintain the specific correction here. For the Westwick telecommunications provider, the direct corrective action is to use an authorized Defender for Endpoint device isolation response where supported.

Question 689

At the Kingsford retail company, a corporate laptop runs without effective Microsoft Defender Antivirus real-time protection due to a local exception. Which corrective action best meets the requirement?

  1. Use Microsoft Defender Vulnerability Management exposure insights and remediation guidance
  2. Apply and monitor appropriate Microsoft Defender Antivirus protection settings for managed endpoints
  3. Grant the workflow identity its required permissions to the target system under least privilege
  4. Evaluate suitable Azure WAF rate-limit or bot protection capabilities for the supported endpoint

Explanation

Correct Answer

B:

The primary failure mode is that endpoint antivirus controls need supported configuration and current threat intelligence to protect file and process activity. The proposed action directly fixes it by requiring the team to apply and monitor appropriate Microsoft Defender Antivirus protection settings for managed endpoints; afterward, verify that a standard safe antivirus test file produces the expected detection on an eligible device. This result addresses the stated challenge at the Kingsford retail company.

Incorrect Answers

A:

The option addresses the separate situation where vulnerability management identifies weaknesses and risk exposure rather than only detecting active malware. For this case, the more appropriate response is to apply and monitor appropriate Microsoft Defender Antivirus protection settings for managed endpoints. For the Kingsford retail company, the direct corrective action is to apply and monitor appropriate Microsoft Defender Antivirus protection settings for managed endpoints.

C:

Grant the workflow identity its required permissions to the target system under least privilege can be useful for another workload, but it leaves the immediate failure unresolved. Here the priority is to apply and monitor appropriate Microsoft Defender Antivirus protection settings for managed endpoints. For the Kingsford retail company, the direct corrective action is to apply and monitor appropriate Microsoft Defender Antivirus protection settings for managed endpoints.

D:

The suggested action is to evaluate suitable Azure WAF rate-limit or bot protection capabilities for the supported endpoint, but the facts at the Kingsford retail company require a correction for the distinct problem that endpoint antivirus controls need supported configuration and current threat intelligence to protect file and process activity.

Question 690

At the Kingsford retail company, a corporate laptop runs without effective Microsoft Defender Antivirus real-time protection due to a local exception. Which underlying issue most directly explains this situation?

  1. Email threat incidents can benefit from automated investigation and corrective steps for supported scenarios
  2. A WAF examines application requests for common web attacks rather than replacing database query parameterization
  3. Threat detection alerts and configuration recommendations provide different types of security evidence
  4. Endpoint antivirus controls need supported configuration and current threat intelligence to protect file and process activity

Explanation

Correct Answer

D:

The problem stems from the fact that endpoint antivirus controls need supported configuration and current threat intelligence to protect file and process activity. A correct solution would apply and monitor appropriate Microsoft Defender Antivirus protection settings for managed endpoints and check that a standard safe antivirus test file produces the expected detection on an eligible device. This result addresses the stated challenge at the Kingsford retail company.

Incorrect Answers

A:

The proposed cause is relevant to defender for office 365 automated investigation, but it does not explain why endpoint antivirus controls need supported configuration and current threat intelligence to protect file and process activity in the reported case. For the Kingsford retail company, the direct corrective action is to apply and monitor appropriate Microsoft Defender Antivirus protection settings for managed endpoints.

B:

A WAF examines application requests for common web attacks rather than replacing database query parameterization. That is not the mechanism that accounts for the stated failure at the Kingsford retail company.

C:

The case does not describe the failure mode involving cloud workload protection alert triage. Its core issue is that endpoint antivirus controls need supported configuration and current threat intelligence to protect file and process activity. For the Kingsford retail company, the direct corrective action is to apply and monitor appropriate Microsoft Defender Antivirus protection settings for managed endpoints.
