Microsoft MS-102 Practice Test 86

Question 850

A bulk script disables accounts with a wildcard matching similar surnames and accidentally targets active employees. What should the administrator do FIRST to correct the problem?

  1. Use immutable object IDs and preview the exact affected identity set before bulk account modifications.
  2. Use mail contacts for external directory recipients that do not require login or hosted mailboxes.
  3. Assign a supported license bundle or group-based licensing policy with required service plans enabled.
  4. Adjust the Microsoft 365 Group privacy and membership governance to meet the approved collaboration boundary.

Explanation

Correct Answer

A:

The deciding issue is display names are not unique stable identifiers for destructive directory automation. The action 'Use immutable object IDs and preview the exact affected identity set before bulk account modifications.' targets that issue rather than a neighboring Microsoft 365 workload. Confirm it by checking: A controlled dry run identifies only the approved offboarding objects and leaves a namesake active.

Incorrect Answers

B:

Creating user principals for address-only contacts introduces needless identity and license exposure. The problem described here is that display names are not unique stable identifiers for destructive directory automation.

C:

An assigned SKU without the intended enabled service plan can leave a workload unavailable. The problem described here is that display names are not unique stable identifiers for destructive directory automation.

D:

Group visibility and membership determine broad collaboration exposure across related workloads. The problem described here is that display names are not unique stable identifiers for destructive directory automation.

Question 851

An enterprise regional helpdesk must manage only employees in its subsidiary but receives tenant-wide User Administrator access. The administrator proposes: Scope supported Entra roles with an administrative unit containing the authorized regional users. What test distinguishes successful remediation from an unrelated improvement?

  1. The helpdesk can update an in-scope user while an out-of-scope user's account is denied.
  2. The analyst can manage approved incidents but cannot modify unrelated Microsoft 365 tenant settings.
  3. The analyst resets a permitted account but cannot alter tenant-wide Conditional Access policies.
  4. The investigation identifies the actor, activation time, justification and approval record where captured.

Explanation

Correct Answer

A:

The administrator plans 'Scope supported Entra roles with an administrative unit containing the authorized regional users.' to correct the fact that administrative units can constrain some role assignments rather than granting every role tenant-wide. The direct acceptance evidence is The helpdesk can update an in-scope user while an out-of-scope user's account is denied. This observation is linked to this change's intended outcome.

Incorrect Answers

B:

The analyst can manage approved incidents but cannot modify unrelated Microsoft 365 tenant settings. However, that result would not establish the required outcome: the helpdesk can update an in-scope user while an out-of-scope user's account is denied.

C:

The analyst resets a permitted account but cannot alter tenant-wide Conditional Access policies. However, that result would not establish the required outcome: the helpdesk can update an in-scope user while an out-of-scope user's account is denied.

D:

The investigation identifies the actor, activation time, justification and approval record where captured. However, that result would not establish the required outcome: the helpdesk can update an in-scope user while an out-of-scope user's account is denied.

Question 852

A vendor should appear in the company address book for employees but must never sign into company services. What should the administrator do FIRST to correct the problem?

  1. Create an appropriate mail contact in the Microsoft 365 admin center instead of a licensed user account.
  2. Reconcile the approved guest identity and correct redundant invitations or assignments.
  3. Review and remove both mailbox access and separate recipient delegation permissions during offboarding.
  4. Review enabled and disabled service plans for the effective Microsoft 365 license assignment.

Explanation

Correct Answer

A:

The deciding issue is mail contacts are address-book objects and are not equivalent to interactive Entra workforce accounts. The action 'Create an appropriate mail contact in the Microsoft 365 admin center instead of a licensed user account.' targets that issue rather than a neighboring Microsoft 365 workload. Confirm it by checking: Employees resolve the vendor's external address in the directory while the contact has no sign-in identity.

Incorrect Answers

B:

Similar display names do not prove two directory objects represent the same security principal. The problem described here is that mail contacts are address-book objects and are not equivalent to interactive Entra workforce accounts.

C:

Full Access and Send As grants have separate lifecycles and must both be audited. The problem described here is that mail contacts are address-book objects and are not equivalent to interactive Entra workforce accounts.

D:

SKU assignment and individual service-plan availability are different settings. That concern does not account for the stated failure: Mail contacts are address-book objects and are not equivalent to interactive Entra workforce accounts. The relevant design change is: Create an appropriate mail contact in the Microsoft 365 admin center instead of a licensed user account.

Question 853

A company marks sensitive financial reports with a filename prefix SECRET but users can still share them without classification controls. The change owner plans to: Apply approved Microsoft Purview sensitivity labels with appropriate protection and sharing settings. Which validation or governance guardrail is best suited to the proposed fix?

  1. Document policy precedence and avoid confusing a sensitivity label with a retention label.
  2. Use least-privilege explorer roles and protect access to sensitive content previews.
  3. Validate label availability and encryption compatibility for each target Microsoft 365 workload.
  4. Consult legal counsel and test representative hold scenarios before enabling disposition automation.

Explanation

Correct Answer

C:

The specific rollout control is Validate label availability and encryption compatibility for each target Microsoft 365 workload. It protects the proposed intervention 'Apply approved Microsoft Purview sensitivity labels with appropriate protection and sharing settings.' against the failure mode that a naming convention is not a machine-enforceable sensitivity label with protection semantics. Success should also be checked through: A labeled test report displays the intended classification and supported access restrictions follow it.

Incorrect Answers

A:

Sensitivity labels address classification and protection; retention controls manage preservation and disposal. The proposed change also needs protection against this risk: A naming convention is not a machine-enforceable sensitivity label with protection semantics. The applicable safeguard is: Validate label availability and encryption compatibility for each target Microsoft 365 workload.

B:

Mail security threat alerts are not an inventory of classified content stored across Microsoft 365. The proposed change also needs protection against this risk: A naming convention is not a machine-enforceable sensitivity label with protection semantics. The applicable safeguard is: Validate label availability and encryption compatibility for each target Microsoft 365 workload.

D:

Competing retention and hold requirements cannot be reduced to one simple earliest-delete timer. The proposed change also needs protection against this risk: A naming convention is not a machine-enforceable sensitivity label with protection semantics. The applicable safeguard is: Validate label availability and encryption compatibility for each target Microsoft 365 workload.

Question 854

A company denies authentication to a certain application for unapproved users but excludes the entire All cloud apps scope by mistake. The administrator proposes: Correct Conditional Access targeting of cloud applications, user groups and policy exclusions. What test distinguishes successful remediation from an unrelated improvement?

  1. A target-app sign-in is denied while approved applications remain accessible as intended.
  2. A simulated policy lockout leaves a monitored emergency administrator able to restore correct access.
  3. A report-only pilot identifies legacy applications and protected identities needing remediation.
  4. A transition pilot shows the blocked user population and a supported enrollment path before enforcement.

Explanation

Correct Answer

A:

The administrator plans 'Correct Conditional Access targeting of cloud applications, user groups and policy exclusions.' to correct the fact that policy existence cannot protect an app omitted from its target scope. The direct acceptance evidence is A target-app sign-in is denied while approved applications remain accessible as intended. This observation is linked to this change's intended outcome.

Incorrect Answers

B:

A simulated policy lockout leaves a monitored emergency administrator able to restore correct access. However, that result would not establish the required outcome: a target-app sign-in is denied while approved applications remain accessible as intended.

C:

A report-only pilot identifies legacy applications and protected identities needing remediation. However, that result would not establish the required outcome: a target-app sign-in is denied while approved applications remain accessible as intended.

D:

A transition pilot shows the blocked user population and a supported enrollment path before enforcement. However, that result would not establish the required outcome: a target-app sign-in is denied while approved applications remain accessible as intended.

Question 855

A tenant has a DLP policy for SharePoint but assumes it also blocks Teams chat messages containing sensitive data. The change owner plans to: Explicitly include supported Microsoft Teams locations in an appropriate Microsoft Purview DLP policy. Which validation or governance guardrail is best suited to the proposed fix?

  1. Check prerequisites and private-channel or shared-channel limitations before enforcement.
  2. Provide platform-specific policy tests and avoid universal coverage statements.
  3. Preserve relevant audit evidence and restrict access to exposed sensitive content.
  4. Protect notification content and require escalation checks when the primary queue is unavailable.

Explanation

Correct Answer

A:

The specific rollout control is Check prerequisites and private-channel or shared-channel limitations before enforcement. It protects the proposed intervention 'Explicitly include supported Microsoft Teams locations in an appropriate Microsoft Purview DLP policy.' against the failure mode that dLP policies target supported workload locations; SharePoint scope does not automatically include Teams chat. Success should also be checked through: A simulated Teams message with protected test data produces the specified enforcement result.

Incorrect Answers

B:

Endpoint DLP features and prerequisites can differ by operating system and device state. The proposed change also needs protection against this risk: DLP policies target supported workload locations; SharePoint scope does not automatically include Teams chat. The applicable safeguard is: Check prerequisites and private-channel or shared-channel limitations before enforcement.

C:

A DLP alert is not conclusive proof that exfiltration succeeded. The proposed change also needs protection against this risk: DLP policies target supported workload locations; SharePoint scope does not automatically include Teams chat. The applicable safeguard is: Check prerequisites and private-channel or shared-channel limitations before enforcement.

D:

A generated compliance alert is not meaningful incident response unless a responsible team acts. The proposed change also needs protection against this risk: DLP policies target supported workload locations; SharePoint scope does not automatically include Teams chat. The applicable safeguard is: Check prerequisites and private-channel or shared-channel limitations before enforcement.

Question 856

An endpoint response policy enables automatic remediation for all devices including production safety controllers. The change owner plans to: Scope Defender automation levels by device groups and criticality after business approval. Which validation or governance guardrail is best suited to the proposed fix?

  1. Validate tenant IDs and revoke accidental test-tenant access before fleet expansion.
  2. Create exception owners and review automated action outcomes regularly.
  3. Document sensor health and supported platform limitations in coverage reports.
  4. Check reboot requirements and scan freshness before closing a remediation ticket.

Explanation

Correct Answer

B:

The specific rollout control is Create exception owners and review automated action outcomes regularly. It protects the proposed intervention 'Scope Defender automation levels by device groups and criticality after business approval.' against the failure mode that automated endpoint actions can interrupt high-availability or safety-sensitive systems. Success should also be checked through: A pilot response remediates eligible workstations without automatically disrupting protected critical controllers.

Incorrect Answers

A:

Onboarding artifacts can embed tenant-specific association information. The proposed change also needs protection against this risk: Automated endpoint actions can interrupt high-availability or safety-sensitive systems. The applicable safeguard is: Create exception owners and review automated action outcomes regularly.

C:

An unassessed device is not equivalent to an assessed device with no findings. The proposed change also needs protection against this risk: Automated endpoint actions can interrupt high-availability or safety-sensitive systems. The applicable safeguard is: Create exception owners and review automated action outcomes regularly.

D:

A patch deployment success message does not prove the endpoint installed and activated the fix. The proposed change also needs protection against this risk: Automated endpoint actions can interrupt high-availability or safety-sensitive systems. The applicable safeguard is: Create exception owners and review automated action outcomes regularly.

Question 857

A SOC investigates a phishing campaign but overlooks Teams chat links because it filters only Exchange message threats. What should the administrator do FIRST to correct the problem?

  1. Use supported Defender attack simulation payload and landing-page configuration approved by the organization.
  2. Update Defender for Office 365 alert recipient configuration and verify routing to a maintained group.
  3. Review Defender for Office 365 alert policy details and correlate policy identifiers with the triggered event.
  4. Use supported Defender for Office 365 collaboration threat investigation across the relevant workloads.

Explanation

Correct Answer

D:

The deciding issue is email-only filters can omit collaboration content protected by supported threat controls. The action 'Use supported Defender for Office 365 collaboration threat investigation across the relevant workloads.' targets that issue rather than a neighboring Microsoft 365 workload. Confirm it by checking: The campaign review includes suspicious collaboration links alongside affected mail messages.

Incorrect Answers

A:

Phishing simulations must not expose passwords to uncontrolled third-party services. The problem described here is that email-only filters can omit collaboration content protected by supported threat controls.

B:

Alert policies lose operational value when recipient lists are not maintained. The problem described here is that email-only filters can omit collaboration content protected by supported threat controls.

C:

An alert label alone is insufficient to understand why detection logic fired. The problem described here is that email-only filters can omit collaboration content protected by supported threat controls.

Question 858

A forest has multiple accounts sharing the same proxy address and project owners expect Entra Connect to assign both correctly. The administrator proposes: Identify and resolve duplicate mail and proxyAddress attributes before directory synchronization. What test distinguishes successful remediation from an unrelated improvement?

  1. The scoped pilot users synchronize through healthy agents with approved attributes.
  2. The cleaned directory reports unique routable proxies and pilot users match intended Microsoft 365 recipients.
  3. Agent health returns to normal and a controlled source attribute change arrives in the cloud.
  4. The reconciliation explains intentionally excluded identities and isolates unexpected failures.

Explanation

Correct Answer

B:

The administrator plans 'Identify and resolve duplicate mail and proxyAddress attributes before directory synchronization.' to correct the fact that a unique mail routing address cannot be reliably assigned to two separate synchronized recipients. The direct acceptance evidence is The cleaned directory reports unique routable proxies and pilot users match intended Microsoft 365 recipients. This observation is linked to this change's intended outcome.

Incorrect Answers

A:

The scoped pilot users synchronize through healthy agents with approved attributes. However, that result would not establish the required outcome: the cleaned directory reports unique routable proxies and pilot users match intended Microsoft 365 recipients.

C:

Agent health returns to normal and a controlled source attribute change arrives in the cloud. However, that result would not establish the required outcome: the cleaned directory reports unique routable proxies and pilot users match intended Microsoft 365 recipients.

D:

The reconciliation explains intentionally excluded identities and isolates unexpected failures. However, that result would not establish the required outcome: the cleaned directory reports unique routable proxies and pilot users match intended Microsoft 365 recipients.

Question 859

A migration team gives users new cloud addresses but fails to align source UPN suffixes to a verified Microsoft 365 domain. What should the administrator do FIRST to correct the problem?

  1. Configure Connect Health notifications and routinely review export and synchronization error trends.
  2. Prepare and normalize permitted source UPN suffixes and verify the relevant cloud tenant domain.
  3. Deploy the supported agent redundancy and monitor each Cloud Sync configuration health.
  4. Troubleshoot agent registration, outbound connectivity and service configuration for the failing Cloud Sync agent.

Explanation

Correct Answer

B:

The deciding issue is an unverified or invalid sign-in suffix can prevent desired cloud UPN alignment. The action 'Prepare and normalize permitted source UPN suffixes and verify the relevant cloud tenant domain.' targets that issue rather than a neighboring Microsoft 365 workload. Confirm it by checking: Pilot users synchronize with the intended verified sign-in suffix without unexpected fallback addresses.

Incorrect Answers

A:

Unmonitored sync errors can persist even when overall server availability appears normal. The problem described here is that an unverified or invalid sign-in suffix can prevent desired cloud UPN alignment.

C:

Single-agent topology can make cloud synchronization dependent on one server's availability. The problem described here is that an unverified or invalid sign-in suffix can prevent desired cloud UPN alignment.

D:

An agent-to-service communication failure is distinct from user password quality or sign-in status. The problem described here is that an unverified or invalid sign-in suffix can prevent desired cloud UPN alignment.

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.
