Microsoft MS-102 Practice Test 87

Question 860

A defender analyst wants to investigate email-to-endpoint lateral movement but filters advanced hunting data to email events only. The administrator proposes: Join or correlate relevant Defender XDR telemetry across mail, identity and device tables where supported. What test distinguishes successful remediation from an unrelated improvement?

  1. A query returns an ordered attack timeline from suspicious email to affected endpoint activity.
  2. The team identifies a concrete exposure path and documents the control that removes its highest-risk link.
  3. The approved plan first addresses a high-impact identity weakness even if another action offers more points.
  4. The final classification cites actual malicious encryption or extortion evidence rather than a campaign label alone.

Explanation

Correct Answer

A:

The administrator plans 'Join or correlate relevant Defender XDR telemetry across mail, identity and device tables where supported.' to correct the fact that single-workload hunting can miss subsequent activity that occurs in other Microsoft security products. The direct acceptance evidence is A query returns an ordered attack timeline from suspicious email to affected endpoint activity. This observation is linked to this change's intended outcome.

Incorrect Answers

B:

The team identifies a concrete exposure path and documents the control that removes its highest-risk link. However, that result would not establish the required outcome: a query returns an ordered attack timeline from suspicious email to affected endpoint activity.

C:

The approved plan first addresses a high-impact identity weakness even if another action offers more points. However, that result would not establish the required outcome: a query returns an ordered attack timeline from suspicious email to affected endpoint activity.

D:

The final classification cites actual malicious encryption or extortion evidence rather than a campaign label alone. However, that result would not establish the required outcome: a query returns an ordered attack timeline from suspicious email to affected endpoint activity.

Question 861

A company needs to warn staff before sending payment-card data outside Exchange Online but has no Purview data loss prevention rules. What should the administrator do FIRST to correct the problem?

  1. Review DLP event and alert reports to distinguish sanctioned tests, false positives and actual violations.
  2. Configure supported Microsoft Purview Endpoint DLP with enrolled and compatible devices and relevant file activities.
  3. Review Endpoint DLP policy mode and activity-action configuration for the detected upload operation.
  4. Configure an Exchange Online DLP policy using appropriate sensitive information types and an approved user action.

Explanation

Correct Answer

D:

The deciding issue is content classification alone does not prevent external transmission without an applicable DLP policy. The action 'Configure an Exchange Online DLP policy using appropriate sensitive information types and an approved user action.' targets that issue rather than a neighboring Microsoft 365 workload. Confirm it by checking: A controlled external message containing test card patterns triggers the expected warning or block.

Incorrect Answers

A:

Sensitive-information matches can arise from legitimate test data and do not automatically prove misconduct. The problem described here is that content classification alone does not prevent external transmission without an applicable DLP policy.

B:

Cloud-location DLP rules alone do not govern all local endpoint file operations. The problem described here is that content classification alone does not prevent external transmission without an applicable DLP policy.

C:

Endpoint DLP telemetry can record activities even when enforcement is in audit mode. The problem described here is that content classification alone does not prevent external transmission without an applicable DLP policy.

Question 862

A company introduces Entra Cloud Sync agents in two locations but installs only one agent for a critical production sync process. The administrator proposes: Deploy the supported agent redundancy and monitor each Cloud Sync configuration health. What test distinguishes successful remediation from an unrelated improvement?

  1. The export error clears and the intended recipient retains the unique mail alias.
  2. The pre-sync validation finds no blocking UPN or proxy-address defects in the approved user subset.
  3. The cleaned directory reports unique routable proxies and pilot users match intended Microsoft 365 recipients.
  4. A controlled agent outage does not stop eligible identities from syncing within the defined recovery objective.

Explanation

Correct Answer

D:

The administrator plans 'Deploy the supported agent redundancy and monitor each Cloud Sync configuration health.' to correct the fact that single-agent topology can make cloud synchronization dependent on one server's availability. The direct acceptance evidence is A controlled agent outage does not stop eligible identities from syncing within the defined recovery objective. This observation is linked to this change's intended outcome.

Incorrect Answers

A:

Export cannot safely assign one proxy address to multiple different recipients. That finding would not establish that the current design works. The required evidence is: A controlled agent outage does not stop eligible identities from syncing within the defined recovery objective.

B:

Directory synchronization can fail or create duplicate identities when legacy attributes violate cloud requirements. That finding would not establish that the current design works. The required evidence is: A controlled agent outage does not stop eligible identities from syncing within the defined recovery objective.

C:

A unique mail routing address cannot be reliably assigned to two separate synchronized recipients. That finding would not establish that the current design works. The required evidence is: A controlled agent outage does not stop eligible identities from syncing within the defined recovery objective.

Question 863

A tenant leaves permanent Global Administrator assignments active for engineering contractors who need emergency changes only. The team believes no other action is necessary. Which failure mechanism best matches the observed facts?

  1. Global Administrator has far broader powers than routine delegated helpdesk work requires.
  2. Permanent privileged standing access expands compromise risk beyond the actual maintenance period.
  3. Defender workload permissions can be narrower than broad Entra directory administration.
  4. Read-only access does not grant role-specific management permissions for collaboration workloads.

Explanation

Correct Answer

B:

The actual failure mechanism is Permanent privileged standing access expands compromise risk beyond the actual maintenance period. Its relevance follows from the stated tenant facts, not just a generic security recommendation. Correct it by use Microsoft Entra Privileged Identity Management to make supported privileged roles eligible for time-limited activation. Then verify: An engineer activates the approved role temporarily and loses active permissions at expiry.

Incorrect Answers

A:

Global Administrator has far broader powers than routine delegated helpdesk work requires. The stated symptoms instead indicate that permanent privileged standing access expands compromise risk beyond the actual maintenance period.

C:

Defender workload permissions can be narrower than broad Entra directory administration. The stated symptoms instead indicate that permanent privileged standing access expands compromise risk beyond the actual maintenance period.

D:

Read-only access does not grant role-specific management permissions for collaboration workloads. The stated symptoms instead indicate that permanent privileged standing access expands compromise risk beyond the actual maintenance period.

Question 864

A company adds a custom sign-in domain but users still authenticate using an unexpected default onmicrosoft.com suffix. The change owner plans to: Add and verify the custom domain, then set the approved user principal names where appropriate. Which validation or governance guardrail is best suited to the proposed fix?

  1. Protect restored sensitive mail and document recovery scope, data overwrite risks and audit evidence.
  2. Validate reporting scope and sensitivity before interpreting individual-level adoption patterns.
  3. Review account synchronization and service dependencies before changing UPNs for existing users.
  4. Validate supported workloads, protection policies, licensing and recovery-time expectations before rollout.

Explanation

Correct Answer

C:

The specific rollout control is Review account synchronization and service dependencies before changing UPNs for existing users. It protects the proposed intervention 'Add and verify the custom domain, then set the approved user principal names where appropriate.' against the failure mode that an added domain does not automatically rewrite every existing user's sign-in name or primary email address. Success should also be checked through: A pilot account signs in with the custom verified domain while its mailbox and assignments remain consistent.

Incorrect Answers

A:

A configured backup policy does not demonstrate successful restoration or adequate permissions. The proposed change also needs protection against this risk: An added domain does not automatically rewrite every existing user's sign-in name or primary email address. The applicable safeguard is: Review account synchronization and service dependencies before changing UPNs for existing users.

B:

Adoption and usage reports summarize activity over defined intervals, not a real-time file integrity ledger. The proposed change also needs protection against this risk: An added domain does not automatically rewrite every existing user's sign-in name or primary email address. The applicable safeguard is: Review account synchronization and service dependencies before changing UPNs for existing users.

D:

Retention governance and operational backup restoration have different objectives and recovery mechanisms. The proposed change also needs protection against this risk: An added domain does not automatically rewrite every existing user's sign-in name or primary email address. The applicable safeguard is: Review account synchronization and service dependencies before changing UPNs for existing users.

Question 865

An admin removes an employee from a shared mailbox but the employee retains independent Send As delegation. What should the administrator do FIRST to correct the problem?

  1. Review and remove both mailbox access and separate recipient delegation permissions during offboarding.
  2. Review enabled and disabled service plans for the effective Microsoft 365 license assignment.
  3. Update identity lifecycle attributes and reconcile role and group memberships to the new job.
  4. Block and deprovision the Microsoft Entra user account according to the approved offboarding workflow.

Explanation

Correct Answer

A:

The deciding issue is full Access and Send As grants have separate lifecycles and must both be audited. The action 'Review and remove both mailbox access and separate recipient delegation permissions during offboarding.' targets that issue rather than a neighboring Microsoft 365 workload. Confirm it by checking: The departed employee cannot open the mailbox or submit messages as that shared sender.

Incorrect Answers

B:

SKU assignment and individual service-plan availability are different settings. That concern does not account for the stated failure: Full Access and Send As grants have separate lifecycles and must both be audited. The relevant design change is: Review and remove both mailbox access and separate recipient delegation permissions during offboarding.

C:

Directory profile changes alone do not guarantee every downstream entitlement is removed. The problem described here is that full Access and Send As grants have separate lifecycles and must both be audited.

D:

Removing a collaboration membership does not disable an identity or revoke every active session. The problem described here is that full Access and Send As grants have separate lifecycles and must both be audited.

Question 866

A company deploys Defender for Endpoint but gives every local support technician portal access to live-response functionality. The team believes no other action is necessary. Which failure mechanism best matches the observed facts?

  1. Automated endpoint actions can interrupt high-availability or safety-sensitive systems.
  2. Device telemetry enrollment and advanced endpoint response administration are different permissions.
  3. License entitlement alone does not deploy or enforce device security settings.
  4. Raw vulnerability counts do not rank the practical business impact of each exposure.

Explanation

Correct Answer

B:

The actual failure mechanism is Device telemetry enrollment and advanced endpoint response administration are different permissions. Its relevance follows from the stated tenant facts, not just a generic security recommendation. Correct it by separate endpoint onboarding administration from sensitive Defender response roles using least privilege. Then verify: A helpdesk technician can view approved device status without arbitrary remote response execution.

Incorrect Answers

A:

Automated endpoint actions can interrupt high-availability or safety-sensitive systems. The stated symptoms instead indicate that device telemetry enrollment and advanced endpoint response administration are different permissions.

C:

License entitlement alone does not deploy or enforce device security settings. The stated symptoms instead indicate that device telemetry enrollment and advanced endpoint response administration are different permissions.

D:

Raw vulnerability counts do not rank the practical business impact of each exposure. The stated symptoms instead indicate that device telemetry enrollment and advanced endpoint response administration are different permissions.

Question 867

A tenant implements access restrictions for administrators without creating a mechanism to recover from misconfigured policies. The change owner plans to: Plan dedicated emergency-access accounts and staged Conditional Access deployment with recovery procedures. Which validation or governance guardrail is best suited to the proposed fix?

  1. Protect break-glass credentials separately and alert on every emergency sign-in.
  2. Validate cross-tenant access and licensing implications before broad guest restrictions.
  3. Revoke test sessions only in an approved environment and inspect sign-in token details.
  4. Avoid unreviewed permanent blocks when a supported user verification can resolve ambiguity.

Explanation

Correct Answer

A:

The specific rollout control is Protect break-glass credentials separately and alert on every emergency sign-in. It protects the proposed intervention 'Plan dedicated emergency-access accounts and staged Conditional Access deployment with recovery procedures.' against the failure mode that tenant-wide access control errors can lock out normal administrators without a recovery path. Success should also be checked through: A simulated policy lockout leaves a monitored emergency administrator able to restore correct access.

Incorrect Answers

B:

Different identity populations may require different access controls and device trust models. The proposed change also needs protection against this risk: Tenant-wide access control errors can lock out normal administrators without a recovery path. The applicable safeguard is: Protect break-glass credentials separately and alert on every emergency sign-in.

C:

Existing sessions and authentication claims can satisfy controls without an apparent new MFA prompt. The proposed change also needs protection against this risk: Tenant-wide access control errors can lock out normal administrators without a recovery path. The applicable safeguard is: Protect break-glass credentials separately and alert on every emergency sign-in.

D:

Automated risk scoring can produce signals requiring investigation and proportional response. The proposed change also needs protection against this risk: Tenant-wide access control errors can lock out normal administrators without a recovery path. The applicable safeguard is: Protect break-glass credentials separately and alert on every emergency sign-in.

Question 868

An organization onboards Linux servers to Defender for Endpoint using a Windows-only onboarding script. The team believes no other action is necessary. Which failure mechanism best matches the observed facts?

  1. Security patching can create application incompatibility even when the patch is technically necessary.
  2. A patch deployment success message does not prove the endpoint installed and activated the fix.
  3. Endpoint onboarding methods differ by platform and cannot be blindly reused across OS families.
  4. Broad exclusions can create blind spots far larger than the original performance problem.

Explanation

Correct Answer

C:

The actual failure mechanism is Endpoint onboarding methods differ by platform and cannot be blindly reused across OS families. Its relevance follows from the stated tenant facts, not just a generic security recommendation. Correct it by choose the supported Microsoft Defender for Endpoint onboarding package and deployment workflow for Linux. Then verify: The Linux test host reports healthy onboarded status and detections under the intended tenant.

Incorrect Answers

A:

Security patching can create application incompatibility even when the patch is technically necessary. The stated symptoms instead indicate that endpoint onboarding methods differ by platform and cannot be blindly reused across OS families.

B:

A patch deployment success message does not prove the endpoint installed and activated the fix. The stated symptoms instead indicate that endpoint onboarding methods differ by platform and cannot be blindly reused across OS families.

D:

Broad exclusions can create blind spots far larger than the original performance problem. The stated symptoms instead indicate that endpoint onboarding methods differ by platform and cannot be blindly reused across OS families.

Question 869

A tenant has a Defender for Cloud Apps Microsoft 365 connector that stopped ingesting events after an admin's credential changes. The team believes no other action is necessary. Which failure mechanism best matches the observed facts?

  1. A previously configured connector can lose the permissions needed for continued ingestion.
  2. A Microsoft 365 tenant app list alone cannot enumerate shadow cloud use across endpoints.
  3. Unspecific manual reporting cannot reliably detect defined high-risk cloud app activity.
  4. Activity logging coverage is bounded by product retention, permissions and available connectors.

Explanation

Correct Answer

A:

The actual failure mechanism is A previously configured connector can lose the permissions needed for continued ingestion. Its relevance follows from the stated tenant facts, not just a generic security recommendation. Correct it by reauthorize or repair the supported Defender for Cloud Apps app connector and monitor its health. Then verify: A fresh Microsoft 365 activity event arrives after repairing connector authorization.

Incorrect Answers

B:

A Microsoft 365 tenant app list alone cannot enumerate shadow cloud use across endpoints. The stated symptoms instead indicate that a previously configured connector can lose the permissions needed for continued ingestion.

C:

Unspecific manual reporting cannot reliably detect defined high-risk cloud app activity. The stated symptoms instead indicate that a previously configured connector can lose the permissions needed for continued ingestion.

D:

Activity logging coverage is bounded by product retention, permissions and available connectors. The stated symptoms instead indicate that a previously configured connector can lose the permissions needed for continued ingestion.

Question 870

A SOC sees repeated unusual process execution on multiple hosts but relies only on the incident summary card. What should the administrator do FIRST to correct the problem?

  1. Rank Microsoft Secure Score and exposure improvement actions by threat relevance, coverage and change feasibility.
  2. Validate the actual tenant security control configuration associated with the Secure Score action.
  3. Explain Defender XDR reporting scope and choose supported hunting or incident feeds for time-critical investigation.
  4. Use Defender XDR advanced hunting KQL to scope process activity across supported device telemetry.

Explanation

Correct Answer

D:

The deciding issue is incident summaries may omit the detailed event relationships required for broad threat scoping. The action 'Use Defender XDR advanced hunting KQL to scope process activity across supported device telemetry.' targets that issue rather than a neighboring Microsoft 365 workload. Confirm it by checking: A test query returns the affected host IDs, timestamps and matching process indicators.

Incorrect Answers

A:

Scoring and security value are related but not identical for all enterprise risk contexts. The problem described here is that incident summaries may omit the detailed event relationships required for broad threat scoping.

B:

Administrative completion markers do not always demonstrate that the preventive control is effective. The problem described here is that incident summaries may omit the detailed event relationships required for broad threat scoping.

C:

Periodic analytical reports and real-time detection pipelines are different operational services. That concern does not account for the stated failure: Incident summaries may omit the detailed event relationships required for broad threat scoping. The relevant design change is: Use Defender XDR advanced hunting KQL to scope process activity across supported device telemetry.
