Microsoft SC-900 Practice Test 73

Question 720

At the Cedarport cloud software developer, a user account performs unusually large downloads from a connected SaaS platform and no alert is reviewed. Which ongoing control best prevents this issue from recurring?

  1. Audit SOC role assignments and analyst responsibilities periodically
  2. Revisit DDoS plan scope when the public IP estate expands
  3. Review protected account scope and exclusions during migrations
  4. Tune anomaly thresholds and cloud connector coverage periodically

Explanation

Correct Answer

D:

This control works beyond the initial remediation because it requires the team to tune anomaly thresholds and cloud connector coverage periodically. This result addresses the stated challenge at the Cedarport cloud software developer.

Incorrect Answers

A:

That routine supports defender portal role-based investigation, but the relevant ongoing risk requires the team to tune anomaly thresholds and cloud connector coverage periodically. For the Cedarport cloud software developer, the direct corrective action is to configure eligible cloud activity anomaly detection and incident review in Defender for Cloud Apps.

B:

The suggested review does not track the condition behind the incident. Sustained improvement requires the team to tune anomaly thresholds and cloud connector coverage periodically. For the Cedarport cloud software developer, the direct corrective action is to configure eligible cloud activity anomaly detection and incident review in Defender for Cloud Apps.

C:

Review protected account scope and exclusions during migrations is not the primary recurring safeguard for this problem. The team should tune anomaly thresholds and cloud connector coverage periodically. For the Cedarport cloud software developer, the direct corrective action is to configure eligible cloud activity anomaly detection and incident review in Defender for Cloud Apps.

Question 721

At the Pinecrest insurance organization, an organization needs detection of suspicious on-premises Active Directory activity but expects Entra cloud sign-in logs alone to reveal all domain attacks. Which implementation choice best addresses the situation?

  1. Evaluate supported Defender XDR automated investigation and response with approved action safeguards
  2. Deploy supported Microsoft Defender for Identity sensor coverage for eligible AD DS environments
  3. Select appropriate Sentinel and Log Analytics ingestion and retention settings for approved investigation needs
  4. Evaluate the appropriate Microsoft Defender for Servers protection plan for the required VM security capabilities

Explanation

Correct Answer

B:

Deploy supported Microsoft Defender for Identity sensor coverage for eligible AD DS environments is the best response because on-premises domain identity threat telemetry requires visibility into the relevant domain services. A focused validation would establish that a pilot domain controller reports healthy Defender for Identity sensor status and expected events. This result addresses the stated challenge at the Pinecrest insurance organization.

Incorrect Answers

A:

This alternative would be suitable where automated investigation can accelerate evidence collection and recommended remediation for supported detections. It does not by itself resolve the need to deploy supported Microsoft Defender for Identity sensor coverage for eligible AD DS environments. For the Pinecrest insurance organization, the direct corrective action is to deploy supported Microsoft Defender for Identity sensor coverage for eligible AD DS environments.

C:

The option addresses the separate situation where log storage and ingestion choices affect cost and the period of evidence available to security investigators. For this case, the more appropriate response is to deploy supported Microsoft Defender for Identity sensor coverage for eligible AD DS environments. For the Pinecrest insurance organization, the direct corrective action is to deploy supported Microsoft Defender for Identity sensor coverage for eligible AD DS environments.

D:

This focuses on defender for servers plan; it does not directly correct the condition that on-premises domain identity threat telemetry requires visibility into the relevant domain services. For the Pinecrest insurance organization, the direct corrective action is to deploy supported Microsoft Defender for Identity sensor coverage for eligible AD DS environments.

Question 722

At the Pinecrest insurance organization, an organization needs detection of suspicious on-premises Active Directory activity but expects Entra cloud sign-in logs alone to reveal all domain attacks. What risk should the team identify as the primary issue?

  1. An incident-level view reduces fragmented assessment of alerts that share entities and attack context
  2. Application requests can exhaust a service even if individual URLs are syntactically legitimate
  3. On-premises domain identity threat telemetry requires visibility into the relevant domain services
  4. Layer-seven destination policies can be based on supported domain-aware rules rather than only network addresses

Explanation

Correct Answer

C:

The evidence indicates that on-premises domain identity threat telemetry requires visibility into the relevant domain services. The appropriate response is to deploy supported Microsoft Defender for Identity sensor coverage for eligible AD DS environments and demonstrate that a pilot domain controller reports healthy Defender for Identity sensor status and expected events. This result addresses the stated challenge at the Pinecrest insurance organization.

Incorrect Answers

A:

This explanation belongs to a different security or compliance situation. In this case, the observable gap is that on-premises domain identity threat telemetry requires visibility into the relevant domain services. For the Pinecrest insurance organization, the direct corrective action is to deploy supported Microsoft Defender for Identity sensor coverage for eligible AD DS environments.

B:

Application requests can exhaust a service even if individual URLs are syntactically legitimate. That may occur elsewhere, but the evidence at the Pinecrest insurance organization instead points to the fact that on-premises domain identity threat telemetry requires visibility into the relevant domain services.

D:

Layer-seven destination policies can be based on supported domain-aware rules rather than only network addresses. That is not the mechanism that accounts for the stated failure at the Pinecrest insurance organization.

Question 723

At the Pinecrest insurance organization, an organization needs detection of suspicious on-premises Active Directory activity but expects Entra cloud sign-in logs alone to reveal all domain attacks. What is the strongest acceptance test for this change?

  1. A sampled device shows its known missing security update and recommended remediation
  2. A pilot domain controller reports healthy Defender for Identity sensor status and expected events
  3. A sample incident reveals linked user and host evidence within the investigation view
  4. An authorized operator reaches the VM through Bastion while direct internet RDP access remains blocked

Explanation

Correct Answer

B:

The team can confirm the fix by showing that a pilot domain controller reports healthy Defender for Identity sensor status and expected events. This aligns with the corrective design to deploy supported Microsoft Defender for Identity sensor coverage for eligible AD DS environments. This result addresses the stated challenge at the Pinecrest insurance organization.

Incorrect Answers

A:

That observation may be useful for another security or compliance workflow, but the current acceptance test must demonstrate that a pilot domain controller reports healthy Defender for Identity sensor status and expected events. For the Pinecrest insurance organization, the direct corrective action is to deploy supported Microsoft Defender for Identity sensor coverage for eligible AD DS environments.

C:

The alternative checks whether a sample incident reveals linked user and host evidence within the investigation view, which is not the direct acceptance criterion for the stated problem. The required result is that a pilot domain controller reports healthy Defender for Identity sensor status and expected events. For the Pinecrest insurance organization, the direct corrective action is to deploy supported Microsoft Defender for Identity sensor coverage for eligible AD DS environments.

D:

This result would validate azure bastion vm administration, not the intended improvement. The needed observation is that a pilot domain controller reports healthy Defender for Identity sensor status and expected events. For the Pinecrest insurance organization, the direct corrective action is to deploy supported Microsoft Defender for Identity sensor coverage for eligible AD DS environments.

Question 724

At the Pinecrest insurance organization, an organization needs detection of suspicious on-premises Active Directory activity but expects Entra cloud sign-in logs alone to reveal all domain attacks. Which setting or practice should be reviewed in future?

  1. Review sensor health after domain controller replacement
  2. Review timeline data retention and endpoint sensor health
  3. Review DDoS monitoring recipients after operations staffing changes
  4. Maintain tested queries when source table schemas change

Explanation

Correct Answer

A:

After implementation, the team should review sensor health after domain controller replacement as the appropriate recurring safeguard against the identified issue. This result addresses the stated challenge at the Pinecrest insurance organization.

Incorrect Answers

B:

This is a maintenance action for a different security or compliance situation, rather than the one that originally failed because on-premises domain identity threat telemetry requires visibility into the relevant domain services. For the Pinecrest insurance organization, the direct corrective action is to deploy supported Microsoft Defender for Identity sensor coverage for eligible AD DS environments.

C:

The option would have the team review DDoS monitoring recipients after operations staffing changes. For this situation, the preventive control should instead be to review sensor health after domain controller replacement. For the Pinecrest insurance organization, the direct corrective action is to deploy supported Microsoft Defender for Identity sensor coverage for eligible AD DS environments.

D:

Although the proposed practice may address cases where KQL allows filtered aggregation and investigation of telemetry in supported Log Analytics tables, it does not maintain the specific correction here. For the Pinecrest insurance organization, the direct corrective action is to deploy supported Microsoft Defender for Identity sensor coverage for eligible AD DS environments.

Question 725

At the Dartwood legal services firm, an attacker uses stolen credentials to move between on-premises domain hosts but only endpoint antivirus alerts are reviewed. Which corrective action best meets the requirement?

  1. Evaluate supported Defender for Endpoint attack surface reduction rules for the targeted behavior
  2. Use Defender for Identity identity threat detections alongside endpoint evidence
  3. Evaluate supported just-in-time VM access capabilities where available to limit the exposure window
  4. Evaluate Azure Bastion for the specific managed VM session instead of unnecessary full-network connectivity

Explanation

Correct Answer

B:

The primary failure mode is that identity threat protection can reveal suspicious directory authentication and lateral movement behavior. The proposed action directly fixes it by requiring the team to use Defender for Identity identity threat detections alongside endpoint evidence; afterward, verify that a safe simulation yields identity evidence linked to the suspected account or host. This result addresses the stated challenge at the Dartwood legal services firm.

Incorrect Answers

A:

The option addresses the separate situation where attack surface reduction can block classes of risky application behavior before exploitation. For this case, the more appropriate response is to use Defender for Identity identity threat detections alongside endpoint evidence. For the Dartwood legal services firm, the direct corrective action is to use Defender for Identity identity threat detections alongside endpoint evidence.

C:

Evaluate supported just-in-time VM access capabilities where available to limit the exposure window can be useful for another workload, but it leaves the immediate failure unresolved. Here the priority is to use Defender for Identity identity threat detections alongside endpoint evidence. For the Dartwood legal services firm, the direct corrective action is to use Defender for Identity identity threat detections alongside endpoint evidence.

D:

The suggested action is to evaluate Azure Bastion for the specific managed VM session instead of unnecessary full-network connectivity, but the facts at the Dartwood legal services firm require a correction for the distinct problem that identity threat protection can reveal suspicious directory authentication and lateral movement behavior.

Question 726

At the Dartwood legal services firm, an attacker uses stolen credentials to move between on-premises domain hosts but only endpoint antivirus alerts are reviewed. Which underlying issue most directly explains this situation?

  1. Software inventory helps expose outdated components even before an attack alert exists
  2. An NSG filters traffic at the configured subnet or network-interface boundary using security rules
  3. Posture reporting and resource policy enforcement address related but different stages of governance
  4. Identity threat protection can reveal suspicious directory authentication and lateral movement behavior

Explanation

Correct Answer

D:

The problem stems from the fact that identity threat protection can reveal suspicious directory authentication and lateral movement behavior. A correct solution would use Defender for Identity identity threat detections alongside endpoint evidence and check that a safe simulation yields identity evidence linked to the suspected account or host. This result addresses the stated challenge at the Dartwood legal services firm.

Incorrect Answers

A:

The proposed cause is relevant to defender vulnerability management software inventory, but it does not explain why identity threat protection can reveal suspicious directory authentication and lateral movement behavior in the reported case. For the Dartwood legal services firm, the direct corrective action is to use Defender for Identity identity threat detections alongside endpoint evidence.

B:

An NSG filters traffic at the configured subnet or network-interface boundary using security rules. That is not the mechanism that accounts for the stated failure at the Dartwood legal services firm.

C:

The case does not describe the failure mode involving azure policy versus defender cloud. Its core issue is that identity threat protection can reveal suspicious directory authentication and lateral movement behavior. For the Dartwood legal services firm, the direct corrective action is to use Defender for Identity identity threat detections alongside endpoint evidence.

Question 727

At the Dartwood legal services firm, an attacker uses stolen credentials to move between on-premises domain hosts but only endpoint antivirus alerts are reviewed. What evidence would justify considering this concern addressed?

  1. A safe simulation yields identity evidence linked to the suspected account or host
  2. A sample query correlates known device and identity events for the intended incident
  3. The control test distinguishes a denied port from a detected HTTP attack payload
  4. A safe supported test validates expected protection telemetry and incident handling for a storage account

Explanation

Correct Answer

A:

This tests the real business behavior: a safe simulation yields identity evidence linked to the suspected account or host. It specifically checks whether the risk that identity threat protection can reveal suspicious directory authentication and lateral movement behavior has been reduced. This result addresses the stated challenge at the Dartwood legal services firm.

Incorrect Answers

B:

This result would validate defender xdr advanced hunting, not the intended improvement. The needed observation is that a safe simulation yields identity evidence linked to the suspected account or host. For the Dartwood legal services firm, the direct corrective action is to use Defender for Identity identity threat detections alongside endpoint evidence.

C:

This verifies a separate issue in security administration. It does not prove that a safe simulation yields identity evidence linked to the suspected account or host for the reported situation. For the Dartwood legal services firm, the direct corrective action is to use Defender for Identity identity threat detections alongside endpoint evidence.

D:

The cited result is too remote from the corrective action to use Defender for Identity identity threat detections alongside endpoint evidence. The direct evidence should show that a safe simulation yields identity evidence linked to the suspected account or host. For the Dartwood legal services firm, the direct corrective action is to use Defender for Identity identity threat detections alongside endpoint evidence.

Question 728

At the Dartwood legal services firm, an attacker uses stolen credentials to move between on-premises domain hosts but only endpoint antivirus alerts are reviewed. How should the organization sustain the improvement?

  1. Review ownership and overdue remediation requests periodically
  2. Review JIT rules and eligible resource coverage after VM changes
  3. Review detection fidelity after Active Directory topology changes
  4. Review subscription coverage when new workloads are deployed

Explanation

Correct Answer

C:

The continuing safeguard is to review detection fidelity after Active Directory topology changes. It helps avoid the original condition: identity threat protection can reveal suspicious directory authentication and lateral movement behavior. This result addresses the stated challenge at the Dartwood legal services firm.

Incorrect Answers

A:

The option would have the team review ownership and overdue remediation requests periodically. For this situation, the preventive control should instead be to review detection fidelity after Active Directory topology changes. For the Dartwood legal services firm, the direct corrective action is to use Defender for Identity identity threat detections alongside endpoint evidence.

B:

Although the proposed practice may address cases where time-bounded management access can reduce the risk of always-open administrative ports, it does not maintain the specific correction here. For the Dartwood legal services firm, the direct corrective action is to use Defender for Identity identity threat detections alongside endpoint evidence.

D:

The suggested review does not track the condition behind the incident. Sustained improvement requires the team to review detection fidelity after Active Directory topology changes. For the Dartwood legal services firm, the direct corrective action is to use Defender for Identity identity threat detections alongside endpoint evidence.

Question 729

At the Tarnbridge insurance organization, unknown accounts enumerate directory objects and privileged groups prior to a suspected domain attack. Which approach best resolves the identified risk?

  1. Review Defender for Identity suspicious reconnaissance indicators in the on-premises environment
  2. Use Microsoft Defender for Cloud Apps cloud discovery capabilities with supported telemetry
  3. Use supported cloud security graph context to assess related resources and effective attack surface
  4. Evaluate Azure Bastion for the specific managed VM session instead of unnecessary full-network connectivity

Explanation

Correct Answer

A:

The reported facts support this change rather than a general platform replacement. The team should review Defender for Identity suspicious reconnaissance indicators in the on-premises environment because abnormal directory enumeration can be a precursor to account or privilege abuse. A suitable test confirms that a controlled detection test identifies the relevant reconnaissance event and entity. This result addresses the stated challenge at the Tarnbridge insurance organization.

Incorrect Answers

B:

The suggested action is to use Microsoft Defender for Cloud Apps cloud discovery capabilities with supported telemetry, but the facts at the Tarnbridge insurance organization require a correction for the distinct problem that abnormal directory enumeration can be a precursor to account or privilege abuse.

C:

This alternative would be suitable where resource risk depends partly on connections and permissions between infrastructure components. It does not by itself resolve the need to review Defender for Identity suspicious reconnaissance indicators in the on-premises environment. For the Tarnbridge insurance organization, the direct corrective action is to review Defender for Identity suspicious reconnaissance indicators in the on-premises environment.

D:

Evaluate Azure Bastion for the specific managed VM session instead of unnecessary full-network connectivity addresses a different kind of problem: bastion is designed for managed RDP or SSH access whereas a VPN supplies broader network path connectivity. Here the reported weakness is that abnormal directory enumeration can be a precursor to account or privilege abuse. For the Tarnbridge insurance organization, the direct corrective action is to review Defender for Identity suspicious reconnaissance indicators in the on-premises environment.

Question 730

At the Tarnbridge insurance organization, unknown accounts enumerate directory objects and privileged groups prior to a suspected domain attack. Which explanation best accounts for the concern?

  1. File detonation and analysis can identify threats not evident from simple file extension or signature checks
  2. Threat detection alerts and configuration recommendations provide different types of security evidence
  3. Resource risk depends partly on connections and permissions between infrastructure components
  4. Abnormal directory enumeration can be a precursor to account or privilege abuse

Explanation

Correct Answer

D:

This identifies the root issue: abnormal directory enumeration can be a precursor to account or privilege abuse. At the Tarnbridge insurance organization, the team should therefore review Defender for Identity suspicious reconnaissance indicators in the on-premises environment.

Incorrect Answers

A:

The case does not describe the failure mode involving defender for office 365 safe attachments. Its core issue is that abnormal directory enumeration can be a precursor to account or privilege abuse. For the Tarnbridge insurance organization, the direct corrective action is to review Defender for Identity suspicious reconnaissance indicators in the on-premises environment.

B:

Although threat detection alerts and configuration recommendations provide different types of security evidence, the presented symptoms do not support that as the primary cause; they indicate that abnormal directory enumeration can be a precursor to account or privilege abuse. For the Tarnbridge insurance organization, the direct corrective action is to review Defender for Identity suspicious reconnaissance indicators in the on-premises environment.

C:

This explanation belongs to a different security or compliance situation. In this case, the observable gap is that abnormal directory enumeration can be a precursor to account or privilege abuse. For the Tarnbridge insurance organization, the direct corrective action is to review Defender for Identity suspicious reconnaissance indicators in the on-premises environment.
