Question 140
Users possess compatible keys but registration is blocked before key attestation starts. Which root cause best explains the described result rather than merely treating its symptoms?
- Disabling the account and revoking refresh sessions do not guarantee every previously issued bearer access token is immediately rejected by every app.
- The passkey authentication method is not enabled or the pilot group is excluded from its policy.
- A generic Require multifactor authentication control was used instead of the appropriate authentication strength.
- One-time TAP and authentication-context timing limits were not accounted for during the two-phase setup.
Explanation
Correct Answer
B:The passkey authentication method is not enabled or the pilot group is excluded from its policy. This is the causal explanation of the observed behavior: users possess compatible keys but registration is blocked before key attestation starts. Address the underlying mechanism with: enable and scope the supported passkey FIDO2 authentication methods policy, including any approved key restrictions. Then confirm: verify a pilot user can register a supported key and use it for Microsoft Entra authentication.
Incorrect Answers
A:This diagnosis fits a separate disable compromised account and sessions incident: A blocked user cannot start a new sign-in but an already issued access token still works temporarily in an app. It does not explain this case's observed failure; the passkey authentication method is not enabled or the pilot group is excluded from its policy.
C:This diagnosis fits a separate phishing-resistant authentication strength incident: An administrator with SMS MFA is still allowed into the portal despite a claimed phishing-resistant requirement. It does not explain this case's observed failure; the passkey authentication method is not enabled or the pilot group is excluded from its policy.
D:This diagnosis fits a separate single-use tap enrollment timing incident: The device enrollment succeeds but the subsequent FIDO2 registration fails after the original single-use TAP and registration window have expired. It does not explain this case's observed failure; the passkey authentication method is not enabled or the pilot group is excluded from its policy.
Question 141
A pilot group has physical security keys but the Entra security-info portal does not offer key registration to its members. The initial implementation works. Which continuing control most directly prevents the same failure or drift from recurring?
- Monitor registered eligible strong methods and exclude emergency access identities through approved safety design.
- Restrict approved authentication-key types and validate registration policies when expanding to new groups.
- Audit who can use SSPR and avoid treating registration alone as proof of eligibility.
- Manage certificate issuance and revocation and validate identity mapping after certificate authority changes.
Explanation
Correct Answer
B:Restrict approved authentication-key types and validate registration policies when expanding to new groups. This reduces future drift after the initial control is deployed: enable and scope the supported passkey FIDO2 authentication methods policy, including any approved key restrictions. Recheck the actual behavior with: verify a pilot user can register a supported key and use it for Microsoft Entra authentication.
Incorrect Answers
A:This control manages future phishing-resistant authentication strength drift, but it does not reduce the continuing exposure in the described passkey fido2 registration policy case. The correct safeguard is: restrict approved authentication-key types and validate registration policies when expanding to new groups.
C:This control manages future sspr user eligibility drift, but it does not reduce the continuing exposure in the described passkey fido2 registration policy case. The correct safeguard is: restrict approved authentication-key types and validate registration policies when expanding to new groups.
D:This control manages future certificate-based authentication drift, but it does not reduce the continuing exposure in the described passkey fido2 registration policy case. The correct safeguard is: restrict approved authentication-key types and validate registration policies when expanding to new groups.
Question 142
Field technicians have managed smart-card certificates and must authenticate with their certificate identity rather than a password. Which proposed configuration or implementation directly meets the stated requirement?
- Configure the supported Microsoft Entra Kerberos trust and matching Windows Hello for Business or cloud Kerberos prerequisites.
- Deploy a supported Windows Hello for Business policy and ensure identity/device prerequisites are met for the pilot.
- Enable and scope the supported passkey FIDO2 authentication methods policy, including any approved key restrictions.
- Configure Microsoft Entra certificate-based authentication with appropriate trust chain, user binding and policy scope.
Explanation
Correct Answer
D:Configure Microsoft Entra certificate-based authentication with appropriate trust chain, user binding and policy scope. The solution acts at the intended identity, policy or application scope. A successful result is testable: attempt sign-in using a mapped certificate and confirm the resulting authentication method in the sign-in details. The competing configuration error is: certificate user binding or trusted issuer configuration does not align with the presented credential.
Incorrect Answers
A:That action implements the separate microsoft entra kerberos for hybrid authentication decision. It is appropriate when hybrid users need supported cloud Kerberos-based access to an approved on-premises resource without prompting for a second password in the planned scenario. The present case instead requires the specific certificate-based authentication change: configure Microsoft Entra certificate-based authentication with appropriate trust chain, user binding and policy scope.
B:That action implements the separate windows hello for business enrollment decision. It is appropriate when company Windows devices should use per-device, key-based Windows Hello for Business sign-in rather than a shared reusable PIN across accounts. The present case instead requires the specific certificate-based authentication change: configure Microsoft Entra certificate-based authentication with appropriate trust chain, user binding and policy scope.
C:That action implements the separate passkey fido2 registration policy decision. It is appropriate when a pilot group has physical security keys but the Entra security-info portal does not offer key registration to its members. The present case instead requires the specific certificate-based authentication change: configure Microsoft Entra certificate-based authentication with appropriate trust chain, user binding and policy scope.
Question 143
Field technicians have managed smart-card certificates and must authenticate with their certificate identity rather than a password. The proposed change is: Configure Microsoft Entra certificate-based authentication with appropriate trust chain, user binding and policy scope. After applying the intended configuration, which observation most directly proves that the required behavior works?
- Obtain a supported Kerberos ticket from a pilot device and confirm access to the intended legacy resource.
- Confirm the user signs in during TAP validity, registers a passkey and then authenticates with the new passkey.
- Complete a pilot enrollment that takes more than ten minutes and confirm the second authorized authentication can register the passkey.
- Attempt sign-in using a mapped certificate and confirm the resulting authentication method in the sign-in details.
Explanation
Correct Answer
D:Attempt sign-in using a mapped certificate and confirm the resulting authentication method in the sign-in details. This directly tests the effective outcome, not merely that a configuration exists. It establishes whether the intended change works: configure Microsoft Entra certificate-based authentication with appropriate trust chain, user binding and policy scope. Failure would be evident in this case: a valid smart-card certificate fails because Entra cannot map its certificate identity to the intended cloud user.
Incorrect Answers
A:The proposed observation checks the different microsoft entra kerberos for hybrid authentication scenario. Even a successful test would not establish the requested outcome here: attempt sign-in using a mapped certificate and confirm the resulting authentication method in the sign-in details.
B:The proposed observation checks the different temporary access pass bootstrap scenario. Even a successful test would not establish the requested outcome here: attempt sign-in using a mapped certificate and confirm the resulting authentication method in the sign-in details.
C:The proposed observation checks the different single-use tap enrollment timing scenario. Even a successful test would not establish the requested outcome here: attempt sign-in using a mapped certificate and confirm the resulting authentication method in the sign-in details.
Question 144
A valid smart-card certificate fails because Entra cannot map its certificate identity to the intended cloud user. Which root cause best explains the described result rather than merely treating its symptoms?
- The on-premises password protection agents or enforcement configuration have not been deployed or activated.
- The TAP authentication method policy does not include that user or is disabled, even though a pass was issued.
- Certificate user binding or trusted issuer configuration does not align with the presented credential.
- A generic Require multifactor authentication control was used instead of the appropriate authentication strength.
Explanation
Correct Answer
C:Certificate user binding or trusted issuer configuration does not align with the presented credential. This is the causal explanation of the observed behavior: a valid smart-card certificate fails because Entra cannot map its certificate identity to the intended cloud user. Address the underlying mechanism with: configure Microsoft Entra certificate-based authentication with appropriate trust chain, user binding and policy scope. Then confirm: attempt sign-in using a mapped certificate and confirm the resulting authentication method in the sign-in details.
Incorrect Answers
A:This diagnosis fits a separate entra password protection on premises incident: A prohibited word is rejected by cloud password changes but still accepted by on-premises AD DS domain controllers. It does not explain this case's observed failure; certificate user binding or trusted issuer configuration does not align with the presented credential.
B:This diagnosis fits a separate temporary access pass bootstrap incident: A TAP is created for a user but the user gets a method-not-allowed error when trying to sign in with it. It does not explain this case's observed failure; certificate user binding or trusted issuer configuration does not align with the presented credential.
D:This diagnosis fits a separate phishing-resistant authentication strength incident: An administrator with SMS MFA is still allowed into the portal despite a claimed phishing-resistant requirement. It does not explain this case's observed failure; certificate user binding or trusted issuer configuration does not align with the presented credential.
Question 145
Field technicians have managed smart-card certificates and must authenticate with their certificate identity rather than a password. The initial implementation works. Which continuing control most directly prevents the same failure or drift from recurring?
- Define short TAP validity and secure issuance procedures; avoid retaining the one-time pass as a standing credential.
- Coordinate app revocation and Continuous Access Evaluation behavior and monitor remaining token exposure.
- Manage certificate issuance and revocation and validate identity mapping after certificate authority changes.
- Monitor agent health and audit-mode findings before enforcement changes across all domain controllers.
Explanation
Correct Answer
C:Manage certificate issuance and revocation and validate identity mapping after certificate authority changes. This reduces future drift after the initial control is deployed: configure Microsoft Entra certificate-based authentication with appropriate trust chain, user binding and policy scope. Recheck the actual behavior with: attempt sign-in using a mapped certificate and confirm the resulting authentication method in the sign-in details.
Incorrect Answers
A:This control manages future temporary access pass bootstrap drift, but it does not reduce the continuing exposure in the described certificate-based authentication case. The correct safeguard is: manage certificate issuance and revocation and validate identity mapping after certificate authority changes.
B:This control manages future disable compromised account and sessions drift, but it does not reduce the continuing exposure in the described certificate-based authentication case. The correct safeguard is: manage certificate issuance and revocation and validate identity mapping after certificate authority changes.
D:This control manages future entra password protection on premises drift, but it does not reduce the continuing exposure in the described certificate-based authentication case. The correct safeguard is: manage certificate issuance and revocation and validate identity mapping after certificate authority changes.
Question 146
A helpdesk wants nonadmin employees to reset forgotten passwords by self-service, using approved verification methods, while high-privilege accounts use distinct controls. Which proposed configuration or implementation directly meets the stated requirement?
- Configure the supported Microsoft Entra Kerberos trust and matching Windows Hello for Business or cloud Kerberos prerequisites.
- Enable SSPR for the intended eligible users and configure authentication methods and registration requirements.
- Apply a Conditional Access authentication strength that requires supported phishing-resistant methods to the intended privileged app and administrators.
- Configure Microsoft Entra certificate-based authentication with appropriate trust chain, user binding and policy scope.
Explanation
Correct Answer
B:Enable SSPR for the intended eligible users and configure authentication methods and registration requirements. The solution acts at the intended identity, policy or application scope. A successful result is testable: test password reset for an included employee and exclusion for an out-of-scope account. The competing configuration error is: the self-service password reset policy scope excludes the user or is disabled.
Incorrect Answers
A:That action implements the separate microsoft entra kerberos for hybrid authentication decision. It is appropriate when hybrid users need supported cloud Kerberos-based access to an approved on-premises resource without prompting for a second password in the planned scenario. The present case instead requires the specific sspr user eligibility change: enable SSPR for the intended eligible users and configure authentication methods and registration requirements.
C:That action implements the separate phishing-resistant authentication strength decision. It is appropriate when a privileged portal must accept only phishing-resistant sign-in methods rather than any SMS or push-based multifactor completion. The present case instead requires the specific sspr user eligibility change: enable SSPR for the intended eligible users and configure authentication methods and registration requirements.
D:That action implements the separate certificate-based authentication decision. It is appropriate when field technicians have managed smart-card certificates and must authenticate with their certificate identity rather than a password. The present case instead requires the specific sspr user eligibility change: enable SSPR for the intended eligible users and configure authentication methods and registration requirements.
Question 147
A helpdesk wants nonadmin employees to reset forgotten passwords by self-service, using approved verification methods, while high-privilege accounts use distinct controls. The proposed change is: Enable SSPR for the intended eligible users and configure authentication methods and registration requirements. After applying the intended configuration, which observation most directly proves that the required behavior works?
- Attempt a new sign-in and test a previously issued refresh token after revocation while recording any access-token limitations.
- Change a test AD DS password to an intentionally prohibited company term and confirm the expected rejection and logs.
- Enroll a test device and confirm a user-bound key and approved local biometric/PIN unlock path works.
- Test password reset for an included employee and exclusion for an out-of-scope account.
Explanation
Correct Answer
D:Test password reset for an included employee and exclusion for an out-of-scope account. This directly tests the effective outcome, not merely that a configuration exists. It establishes whether the intended change works: enable SSPR for the intended eligible users and configure authentication methods and registration requirements. Failure would be evident in this case: a user registered methods but sees that password reset isn't enabled for their account.

Question 148
A user registered methods but sees that password reset isn't enabled for their account. Which root cause best explains the described result rather than merely treating its symptoms?
- The on-premises password protection agents or enforcement configuration have not been deployed or activated.
- The self-service password reset policy scope excludes the user or is disabled.
- The TAP authentication method policy does not include that user or is disabled, even though a pass was issued.
- The Entra Kerberos server/trust or device prerequisite is incomplete despite successful cloud authentication.
Explanation
Correct Answer
B:The self-service password reset policy scope excludes the user or is disabled. This is the causal explanation of the observed behavior: a user registered methods but sees that password reset isn't enabled for their account. Address the underlying mechanism with: enable SSPR for the intended eligible users and configure authentication methods and registration requirements. Then confirm: test password reset for an included employee and exclusion for an out-of-scope account.

- Apply a Conditional Access authentication strength that requires supported phishing-resistant methods to the intended privileged app and administrators.
- Configure Microsoft Entra certificate-based authentication with appropriate trust chain, user binding and policy scope.
- Deploy a supported Windows Hello for Business policy and ensure identity/device prerequisites are met for the pilot.
Explanation
Correct Answer
D:Deploy a supported Windows Hello for Business policy and ensure identity/device prerequisites are met for the pilot. The solution acts at the intended identity, policy or application scope. A successful result is testable: enroll a test device and confirm a user-bound key and approved local biometric/PIN unlock path works. The competing configuration error is: windows Hello for Business keys are bound to a user/device context rather than portable reusable PIN credentials.
Incorrect Answers
A:That action implements the separate microsoft entra kerberos for hybrid authentication decision. It is appropriate when hybrid users need supported cloud Kerberos-based access to an approved on-premises resource without prompting for a second password in the planned scenario. The present case instead requires the specific windows hello for business enrollment change: deploy a supported Windows Hello for Business policy and ensure identity/device prerequisites are met for the pilot.
