Microsoft AB-900 Practice Test 20

Question 190

A sensitive role must be granted only while its holder performs an approved privileged task. What is the most appropriate implementation?

  1. Use assigned group membership with an approval process.
  2. Use supported entitlement management access packages.
  3. Use PIM eligible role activation instead of permanent role assignment.
  4. Configure a Microsoft Entra dynamic group membership rule.

Explanation

Correct Answer

C:

PIM reduces standing role access through controlled activation. This directly addresses temporary high-privilege access.

Incorrect Answers

A:

Assigned groups allow direct intentional membership control. It would support curated manually approved group access, not the stated temporary high-privilege access.

B:

Access packages automate approved and time-limited resource assignment. Its purpose is request-based temporary bundle access; the specified need is temporary high-privilege access.

D:

Dynamic groups evaluate member properties without manual updates. Its purpose is attribute-driven group population; the specified need is temporary high-privilege access.

Question 191

A support agent must identify whether a user has registered supported MFA methods. Which action should the team take?

  1. Issue a policy-approved Temporary Access Pass.
  2. Configure the authentication methods policy for eligible groups.
  3. Reset or re-register permitted user authentication methods.
  4. Review the user's authentication methods and registration details.

Explanation

Correct Answer

D:

Method inventory reports which factors are enrolled. This directly addresses current factor enrollment evidence.

Incorrect Answers

A:

Temporary Access Pass supports bootstrapping and recovery of strong authentication. The action is relevant to first-time credential bootstrap rather than current factor enrollment evidence.

B:

Method policies control allowed registration and use of methods. This helps with scoped passkey eligibility instead of the required current factor enrollment evidence.

C:

Removing obsolete method registration enables controlled credential recovery. The action is relevant to safe replacement of an authentication device rather than current factor enrollment evidence.

Question 192

A high-confidence attacker session must stop using an issued refresh token. What is the most appropriate implementation?

  1. Revoke the account's sign-in sessions and perform approved recovery.
  2. Investigate and remediate Microsoft Entra risky users.
  3. Review the risky sign-in detection and supporting details.
  4. Apply the supported dismissal or remediation workflow for user risk.

Explanation

Correct Answer

A:

Session revocation prevents continued reuse of outstanding authentication sessions. This directly addresses termination of active compromised sign-ins.

Incorrect Answers

B:

User risk evaluates the likelihood of a compromised identity. It is used for response to account-level compromise; this scenario calls for termination of active compromised sign-ins.

C:

Sign-in risk reports assess one authentication event. That addresses troubleshooting one anomalous authentication, whereas the current case requires termination of active compromised sign-ins.

D:

Risk remediation records resolution after recovery action. It is used for clearing a verified recovered user-risk case; this scenario calls for termination of active compromised sign-ins.

Question 193

Investigators need to correlate unusual sign-in events and privileged directory changes. Which action should the team take?

  1. Inspect Microsoft Entra provisioning logs for the target application.
  2. Review both sign-in and audit log evidence in the investigation.
  3. Query the Microsoft Entra sign-in log for the attempt.
  4. Query Microsoft Entra audit logs for the directory update.

Explanation

Correct Answer

B:

Authentication and administrative activity are separate but complementary evidence streams. This directly addresses end-to-end identity incident timeline.

Incorrect Answers

A:

Provisioning logs report account synchronization and processing outcomes. Its purpose is app identity provisioning diagnostics; the specified need is end-to-end identity incident timeline.

C:

Sign-in records capture authentication results and policy enforcement. Its purpose is per-attempt sign-in investigation; the specified need is end-to-end identity incident timeline.

D:

Audit events record administrative directory object changes. It would support attribution of directory updates, not the stated end-to-end identity incident timeline.

Question 194

Emergency recovery accounts must retain an explicitly governed route if broad policies fail. What is the most appropriate implementation?

  1. Use the Conditional Access What If tool with the applicable sign-in conditions.
  2. Inspect the sign-in log Conditional Access results.
  3. Design narrow break-glass exclusions with monitoring and documented controls.
  4. Enable report-only Conditional Access evaluation.

Explanation

Correct Answer

C:

Emergency exclusions prevent tenant-wide lockout while retaining audit oversight. This directly addresses controlled emergency account resilience.

Incorrect Answers

A:

What If evaluates policy applicability under selected inputs. This helps with prospective policy applicability for one scenario instead of the required controlled emergency account resilience.

B:

Real sign-in logs record policies and grants evaluated at that event. The action is relevant to diagnosis of actual conditional access denial rather than controlled emergency account resilience.

D:

Report-only calculates hypothetical results without enforcing denial. The action is relevant to safe initial assessment of policy impact rather than controlled emergency account resilience.

Question 195

Privileged admins should activate sensitive roles only for an approved period. Which action should the team take?

  1. Schedule access reviews for the relevant membership or application.
  2. Publish an entitlement management access package.
  3. Configure appropriate lifecycle workflows in Entra ID Governance.
  4. Manage eligibility and activation with Microsoft Entra PIM.

Explanation

Correct Answer

D:

PIM implements controlled time-limited privilege. This directly addresses just-in-time privileged administration.

Incorrect Answers

A:

Access reviews enable accountable periodic entitlement recertification. It is used for periodic membership review; this scenario calls for just-in-time privileged administration.

B:

Entitlement packages bundle resource access and request policies. That addresses delegated temporary external onboarding, whereas the current case requires just-in-time privileged administration.

C:

Lifecycle workflows automate identity-related events and task sequences. It is used for automated workforce identity transitions; this scenario calls for just-in-time privileged administration.

Question 196

A business analyst needs evidence that licensed users actually adopt Microsoft 365 Copilot. What is the most appropriate implementation?

  1. Review the relevant Copilot usage and analytics dashboards.
  2. Review Microsoft Secure Score.
  3. Review Entra Identity Secure Score.
  4. Review Microsoft Purview Compliance Manager.

Explanation

Correct Answer

A:

Adoption metrics track product use, not security or compliance framework scores. This directly addresses Copilot adoption measurement.

Incorrect Answers

B:

Secure Score aggregates security recommendations across Microsoft security controls. Its purpose is broad cloud security posture recommendations; the specified need is Copilot adoption measurement.

C:

Identity Secure Score focuses identity-specific hardening measurements. It would support identity-only configuration improvements, not the stated Copilot adoption measurement.

D:

Compliance Manager organizes control assessments and improvement actions. Its purpose is formal compliance control improvement; the specified need is Copilot adoption measurement.

Question 197

An external guest finished a project and their access should expire after owner review. Which action should the team take?

  1. Configure cross-tenant access and external collaboration restrictions.
  2. Run an access review and remove the unneeded guest entitlement.
  3. Configure Microsoft Entra B2B collaboration for an invited guest.
  4. Configure B2B direct connect and required cross-tenant policies.

Explanation

Correct Answer

B:

Review-based cleanup reduces persistence of abandoned partner access. This directly addresses expired external collaboration rights.

Incorrect Answers

A:

Tenant collaboration policies govern permitted partner organizations. The action is relevant to partner domain allow/deny governance rather than expired external collaboration rights.

C:

B2B collaboration grants scoped resource access to external identities. The action is relevant to ordinary external guest collaboration rather than expired external collaboration rights.

D:

Direct connect supports certain cross-organization shared-channel experiences. This helps with cross-tenant Teams shared-channel participation instead of the required expired external collaboration rights.

Question 198

Users require phone-based app challenges under an approved MFA policy. What is the most appropriate implementation?

  1. Deploy Windows Hello for Business.
  2. Use a Microsoft Entra Temporary Access Pass.
  3. Configure Microsoft Authenticator push or number matching as supported.
  4. Use a supported FIDO2 security key or passkey.

Explanation

Correct Answer

C:

Authenticator approvals add an interactive possession-based sign-in step. This directly addresses mobile authenticator challenge.

Incorrect Answers

A:

Windows Hello protects asymmetric credentials with a device-local user gesture. That addresses device-bound passwordless Windows sign-in, whereas the current case requires mobile authenticator challenge.

B:

TAP is designed for controlled bootstrap and account recovery. It is used for initial credential enrollment; this scenario calls for mobile authenticator challenge.

D:

FIDO2 authenticator assertions resist phishing and can be portable. It is used for external roaming security-key sign-in; this scenario calls for mobile authenticator challenge.

Question 199

A nightly daemon must run without an employee session and receive only approved application privileges. Which action should the team take?

  1. Configure the application's registration and redirect settings.
  2. Require assignment to the enterprise application service principal.
  3. Use delegated permission scopes for the signed-in user.
  4. Configure approved application permissions for the workload principal.

Explanation

Correct Answer

D:

App-only grants permit background operations within authorized scope. This directly addresses unattended app API execution.

Incorrect Answers

A:

App registration defines the OAuth/OIDC client identity. Its purpose is initial app integration configuration; the specified need is unattended app API execution.

B:

Enterprise app assignments govern permitted organizational access. It would support targeted enterprise application usage, not the stated unattended app API execution.

C:

Delegated scopes act under user identity and permissions. Its purpose is per-user API authorization; the specified need is unattended app API execution.

Question 200

An identity team needs to decide if a privileged role is actively in use or merely eligible for future activation. What is the most appropriate implementation?

  1. Review the PIM eligible and active role assignment states.
  2. Use group-based license assignment.
  3. Define approved named locations in Conditional Access.
  4. Scope authentication methods policies to approved groups.

Explanation

Correct Answer

A:

Eligibility indicates potential activation; active state indicates current authority. This directly addresses accurate temporary privilege state.

Incorrect Answers

B:

Directory membership can trigger license assignment and removal. The action is relevant to lifecycle-based license provisioning rather than accurate temporary privilege state.

C:

Named locations provide reusable network context for sign-in conditions. This helps with trusted office network classification instead of the required accurate temporary privilege state.

D:

Authentication method policy governs permitted method populations. The action is relevant to targeted stronger authentication enrollment rather than accurate temporary privilege state.
