Microsoft SC-900 Practice Test 74

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.

Question 731

At the Tarnbridge insurance organization, unknown accounts enumerate directory objects and privileged groups prior to a suspected domain attack. Which test result best shows the requirement is met?

  1. A safe exercise records both selected account and device actions against the same incident
  2. A test incident process retrieves the protected resource's relevant DDoS metrics and routes an alert
  3. A test from the web test subnet cannot reach protected finance ports while an approved path remains available
  4. A controlled detection test identifies the relevant reconnaissance event and entity

Explanation

Correct Answer

D:

The team can confirm the fix by showing that a controlled detection test identifies the relevant reconnaissance event and entity. This aligns with the corrective design to review Defender for Identity suspicious reconnaissance indicators in the on-premises environment. This result addresses the stated challenge at the Tarnbridge insurance organization.

Incorrect Answers

A:

This verifies a separate issue in security administration. It does not prove that a controlled detection test identifies the relevant reconnaissance event and entity for the reported situation. For the Tarnbridge insurance organization, the direct corrective action is to review Defender for Identity suspicious reconnaissance indicators in the on-premises environment.

B:

The cited result is too remote from the corrective action to review Defender for Identity suspicious reconnaissance indicators in the on-premises environment. The direct evidence should show that a controlled detection test identifies the relevant reconnaissance event and entity. For the Tarnbridge insurance organization, the direct corrective action is to review Defender for Identity suspicious reconnaissance indicators in the on-premises environment.

C:

That observation may be useful for another security or compliance workflow, but the current acceptance test must demonstrate that a controlled detection test identifies the relevant reconnaissance event and entity. For the Tarnbridge insurance organization, the direct corrective action is to review Defender for Identity suspicious reconnaissance indicators in the on-premises environment.

Question 732

At the Tarnbridge insurance organization, unknown accounts enumerate directory objects and privileged groups prior to a suspected domain attack. Which ongoing control best prevents this issue from recurring?

  1. Review alert triage and excluded service identities to reduce noise
  2. Review reopened and unclassified incidents during shift handovers
  3. Review benchmark applicability as regulations and cloud services change
  4. Review protected public endpoints when publishing new internet services

Explanation

Correct Answer

A:

The continuing safeguard is to review alert triage and excluded service identities to reduce noise. It helps avoid the original condition: abnormal directory enumeration can be a precursor to account or privilege abuse. This result addresses the stated challenge at the Tarnbridge insurance organization.

Incorrect Answers

B:

The suggested review does not track the condition behind the incident. Sustained improvement requires the team to review alert triage and excluded service identities to reduce noise. For the Tarnbridge insurance organization, the direct corrective action is to review Defender for Identity suspicious reconnaissance indicators in the on-premises environment.

C:

Review benchmark applicability as regulations and cloud services change is not the primary recurring safeguard for this problem. The team should review alert triage and excluded service identities to reduce noise. For the Tarnbridge insurance organization, the direct corrective action is to review Defender for Identity suspicious reconnaissance indicators in the on-premises environment.

D:

This is a maintenance action for a different security or compliance situation, rather than the one that originally failed because 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 733

At the Fairhaven legal services firm, domain administrators suspect credential misuse but investigate only the affected computer's hardware events. Which implementation choice best addresses the situation?

  1. Configure eligible cloud activity anomaly detection and incident review in Defender for Cloud Apps
  2. Use supported integration between Microsoft Sentinel and Defender XDR for unified incident investigation where configured
  3. Configure supported VNet peering and required route and access rules
  4. Use Defender for Identity account-related investigations and alerts for the on-premises identity

Explanation

Correct Answer

D:

The primary failure mode is that identity-centric evidence can connect abnormal sign-in and directory activity to a compromised account. The proposed action directly fixes it by requiring the team to use Defender for Identity account-related investigations and alerts for the on-premises identity; afterward, verify that a sample identity incident links the suspicious account to its observed domain actions. This result addresses the stated challenge at the Fairhaven legal services firm.

Incorrect Answers

A:

This alternative would be suitable where anomalous cloud behavior can indicate compromise or misuse even when a service's authentication succeeded. It does not by itself resolve the need to use Defender for Identity account-related investigations and alerts for the on-premises identity. For the Fairhaven legal services firm, the direct corrective action is to use Defender for Identity account-related investigations and alerts for the on-premises identity.

B:

Use supported integration between Microsoft Sentinel and Defender XDR for unified incident investigation where configured addresses a different kind of problem: integrated security operations can link product alerts and related incident context across Microsoft workloads. Here the reported weakness is that identity-centric evidence can connect abnormal sign-in and directory activity to a compromised account. For the Fairhaven legal services firm, the direct corrective action is to use Defender for Identity account-related investigations and alerts for the on-premises identity.

C:

The option addresses the separate situation where separate virtual networks are not connected merely because their address spaces or subnet names resemble each other. For this case, the more appropriate response is to use Defender for Identity account-related investigations and alerts for the on-premises identity. For the Fairhaven legal services firm, the direct corrective action is to use Defender for Identity account-related investigations and alerts for the on-premises identity.

Question 734

At the Fairhaven legal services firm, domain administrators suspect credential misuse but investigate only the affected computer's hardware events. What risk should the team identify as the primary issue?

  1. Risk-based remediation considers more than the presence of a published CVE number
  2. Bastion is designed for managed RDP or SSH access whereas a VPN supplies broader network path connectivity
  3. Layer three and four DDoS mitigation addresses a different traffic layer from application HTTP filtering
  4. Identity-centric evidence can connect abnormal sign-in and directory activity to a compromised account

Explanation

Correct Answer

D:

The specific data failure is that identity-centric evidence can connect abnormal sign-in and directory activity to a compromised account. It can be addressed through the controlled change to use Defender for Identity account-related investigations and alerts for the on-premises identity. This result addresses the stated challenge at the Fairhaven legal services firm.

Incorrect Answers

A:

This explanation belongs to a different security or compliance situation. In this case, the observable gap is that identity-centric evidence can connect abnormal sign-in and directory activity to a compromised account. For the Fairhaven legal services firm, the direct corrective action is to use Defender for Identity account-related investigations and alerts for the on-premises identity.

B:

Bastion is designed for managed RDP or SSH access whereas a VPN supplies broader network path connectivity. That may occur elsewhere, but the evidence at the Fairhaven legal services firm instead points to the fact that identity-centric evidence can connect abnormal sign-in and directory activity to a compromised account.

C:

The proposed cause is relevant to ddos versus application waf, but it does not explain why identity-centric evidence can connect abnormal sign-in and directory activity to a compromised account in the reported case. For the Fairhaven legal services firm, the direct corrective action is to use Defender for Identity account-related investigations and alerts for the on-premises identity.

Question 735

At the Fairhaven legal services firm, domain administrators suspect credential misuse but investigate only the affected computer's hardware events. What is the strongest acceptance test for this change?

  1. A safe test activity produces the intended endpoint detection and process evidence
  2. A sample incident reveals linked user and host evidence within the investigation view
  3. A sample identity incident links the suspicious account to its observed domain actions
  4. A safe test incident triggers the intended approved workflow with an auditable action record

Explanation

Correct Answer

C:

This tests the real business behavior: a sample identity incident links the suspicious account to its observed domain actions. It specifically checks whether the risk that identity-centric evidence can connect abnormal sign-in and directory activity to a compromised account has been reduced. This result addresses the stated challenge at the Fairhaven legal services firm.

Incorrect Answers

A:

That observation may be useful for another security or compliance workflow, but the current acceptance test must demonstrate that a sample identity incident links the suspicious account to its observed domain actions. For the Fairhaven legal services firm, the direct corrective action is to use Defender for Identity account-related investigations and alerts for the on-premises identity.

B:

At the Fairhaven legal services firm, a result about sentinel entity investigation would not show that the team corrected the failure where identity-centric evidence can connect abnormal sign-in and directory activity to a compromised account.

D:

This result would validate soar response automation, not the intended improvement. The needed observation is that a sample identity incident links the suspicious account to its observed domain actions. For the Fairhaven legal services firm, the direct corrective action is to use Defender for Identity account-related investigations and alerts for the on-premises identity.

Question 736

At the Fairhaven legal services firm, domain administrators suspect credential misuse but investigate only the affected computer's hardware events. Which setting or practice should be reviewed in future?

  1. Review domain identity telemetry during account containment drills
  2. Review sensor health after domain controller replacement
  3. Review JIT rules and eligible resource coverage after VM changes
  4. Review firewall rule collections as internal services change

Explanation

Correct Answer

A:

After implementation, the team should review domain identity telemetry during account containment drills as the appropriate recurring safeguard against the identified issue. This result addresses the stated challenge at the Fairhaven legal services firm.

Incorrect Answers

B:

This is a maintenance action for a different security or compliance situation, rather than the one that originally failed because identity-centric evidence can connect abnormal sign-in and directory activity to a compromised account. For the Fairhaven legal services firm, the direct corrective action is to use Defender for Identity account-related investigations and alerts for the on-premises identity.

C:

The option would have the team review JIT rules and eligible resource coverage after VM changes. For this situation, the preventive control should instead be to review domain identity telemetry during account containment drills. For the Fairhaven legal services firm, the direct corrective action is to use Defender for Identity account-related investigations and alerts for the on-premises identity.

D:

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 Fairhaven legal services firm, the direct corrective action is to use Defender for Identity account-related investigations and alerts for the on-premises identity.

Question 737

At the Stonehaven insurance organization, an enterprise wants to connect on-premises identity anomalies with Microsoft Defender XDR cloud and endpoint signals. Which corrective action best meets the requirement?

  1. Integrate supported Defender for Identity signals with the unified Defender XDR investigation experience
  2. Use Microsoft Defender for Endpoint endpoint detection and response telemetry for suspicious device behavior
  3. Use Microsoft Sentinel to ingest and analyze suitable security events for centralized SIEM visibility
  4. Use secure score as an improvement indicator rather than a guarantee of zero risk

Explanation

Correct Answer

A:

This is the direct security or compliance remedy: integrate supported Defender for Identity signals with the unified Defender XDR investigation experience. The observed risk is that hybrid identity investigations are strengthened when on-premises directory alerts join cross-product incidents; a passing acceptance check would show that a test alert from the domain sensor is visible in the configured Defender investigation view. This result addresses the stated challenge at the Stonehaven insurance organization.

Incorrect Answers

B:

This focuses on defender for endpoint edr detection; it does not directly correct the condition that hybrid identity investigations are strengthened when on-premises directory alerts join cross-product incidents. For the Stonehaven insurance organization, the direct corrective action is to integrate supported Defender for Identity signals with the unified Defender XDR investigation experience.

C:

Use Microsoft Sentinel to ingest and analyze suitable security events for centralized SIEM visibility can be useful for another workload, but it leaves the immediate failure unresolved. Here the priority is to integrate supported Defender for Identity signals with the unified Defender XDR investigation experience. For the Stonehaven insurance organization, the direct corrective action is to integrate supported Defender for Identity signals with the unified Defender XDR investigation experience.

D:

The suggested action is to use secure score as an improvement indicator rather than a guarantee of zero risk, but the facts at the Stonehaven insurance organization require a correction for the distinct problem that hybrid identity investigations are strengthened when on-premises directory alerts join cross-product incidents.

Question 738

At the Stonehaven insurance organization, an enterprise wants to connect on-premises identity anomalies with Microsoft Defender XDR cloud and endpoint signals. Which underlying issue most directly explains this situation?

  1. Hybrid identity investigations are strengthened when on-premises directory alerts join cross-product incidents
  2. An incident-level view reduces fragmented assessment of alerts that share entities and attack context
  3. Separate virtual networks are not connected merely because their address spaces or subnet names resemble each other
  4. Ingesting logs alone is insufficient for generating intended detection incidents from event conditions

Explanation

Correct Answer

A:

The evidence indicates that hybrid identity investigations are strengthened when on-premises directory alerts join cross-product incidents. The appropriate response is to integrate supported Defender for Identity signals with the unified Defender XDR investigation experience and demonstrate that a test alert from the domain sensor is visible in the configured Defender investigation view. This result addresses the stated challenge at the Stonehaven insurance organization.

Incorrect Answers

B:

An incident-level view reduces fragmented assessment of alerts that share entities and attack context. That is not the mechanism that accounts for the stated failure at the Stonehaven insurance organization.

C:

The case does not describe the failure mode involving vnet peering connectivity. Its core issue is that hybrid identity investigations are strengthened when on-premises directory alerts join cross-product incidents. For the Stonehaven insurance organization, the direct corrective action is to integrate supported Defender for Identity signals with the unified Defender XDR investigation experience.

D:

Although ingesting logs alone is insufficient for generating intended detection incidents from event conditions, the presented symptoms do not support that as the primary cause; they indicate that hybrid identity investigations are strengthened when on-premises directory alerts join cross-product incidents. For the Stonehaven insurance organization, the direct corrective action is to integrate supported Defender for Identity signals with the unified Defender XDR investigation experience.

Question 739

At the Stonehaven insurance organization, an enterprise wants to connect on-premises identity anomalies with Microsoft Defender XDR cloud and endpoint signals. What evidence would justify considering this concern addressed?

  1. A sample incident has an assigned owner final classification and documented response evidence
  2. A controlled request-burst test triggers the intended HTTP traffic policy without blocking normal requests
  3. The protected database appears in the expected Defender coverage inventory and produces the configured alerts on supported tests
  4. A test alert from the domain sensor is visible in the configured Defender investigation view

Explanation

Correct Answer

D:

This is the relevant acceptance result: a test alert from the domain sensor is visible in the configured Defender investigation view. It demonstrates the outcome of choosing to integrate supported Defender for Identity signals with the unified Defender XDR investigation experience. This result addresses the stated challenge at the Stonehaven insurance organization.

Incorrect Answers

A:

The alternative checks whether a sample incident has an assigned owner final classification and documented response evidence, which is not the direct acceptance criterion for the stated problem. The required result is that a test alert from the domain sensor is visible in the configured Defender investigation view. For the Stonehaven insurance organization, the direct corrective action is to integrate supported Defender for Identity signals with the unified Defender XDR investigation experience.

B:

This result would validate waf bot and rate protection, not the intended improvement. The needed observation is that a test alert from the domain sensor is visible in the configured Defender investigation view. For the Stonehaven insurance organization, the direct corrective action is to integrate supported Defender for Identity signals with the unified Defender XDR investigation experience.

C:

This verifies a separate issue in security administration. It does not prove that a test alert from the domain sensor is visible in the configured Defender investigation view for the reported situation. For the Stonehaven insurance organization, the direct corrective action is to integrate supported Defender for Identity signals with the unified Defender XDR investigation experience.

Question 740

At the Stonehaven insurance organization, an enterprise wants to connect on-premises identity anomalies with Microsoft Defender XDR cloud and endpoint signals. How should the organization sustain the improvement?

  1. Review ownership and overdue remediation requests periodically
  2. Review integration and licensing prerequisites after tenant changes
  3. Audit sensor health after infrastructure changes
  4. Review allowed domains and logging after service endpoint changes

Explanation

Correct Answer

B:

For the Stonehaven insurance organization, this maintenance action preserves the fix: review integration and licensing prerequisites after tenant changes. It should be revisited as the workload evolves.

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 integration and licensing prerequisites after tenant changes. For the Stonehaven insurance organization, the direct corrective action is to integrate supported Defender for Identity signals with the unified Defender XDR investigation experience.

C:

That routine supports defender agent configuration coverage, but the relevant ongoing risk requires the team to review integration and licensing prerequisites after tenant changes. For the Stonehaven insurance organization, the direct corrective action is to integrate supported Defender for Identity signals with the unified Defender XDR investigation experience.

D:

The suggested review does not track the condition behind the incident. Sustained improvement requires the team to review integration and licensing prerequisites after tenant changes. For the Stonehaven insurance organization, the direct corrective action is to integrate supported Defender for Identity signals with the unified Defender XDR investigation experience.
