Question 150
Company Windows devices should use per-device, key-based Windows Hello for Business sign-in rather than a shared reusable PIN across accounts. 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.
- 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.
B: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 windows hello for business enrollment change: deploy a supported Windows Hello for Business policy and ensure identity/device prerequisites are met for the pilot.
C: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 windows hello for business enrollment change: deploy a supported Windows Hello for Business policy and ensure identity/device prerequisites are met for the pilot.
Question 151
Company Windows devices should use per-device, key-based Windows Hello for Business sign-in rather than a shared reusable PIN across accounts. The proposed change is: Deploy a supported Windows Hello for Business policy and ensure identity/device prerequisites are met for the pilot. After applying the intended configuration, which observation most directly proves that the required behavior works?
- 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.
- Attempt sign-in using a mapped certificate and confirm the resulting authentication method in the sign-in details.
- Obtain a supported Kerberos ticket from a pilot device and confirm access to the intended legacy resource.
Explanation
Correct Answer
B:Enroll a test device and confirm a user-bound key and approved local biometric/PIN unlock path works. This directly tests the effective outcome, not merely that a configuration exists. It establishes whether the intended change works: deploy a supported Windows Hello for Business policy and ensure identity/device prerequisites are met for the pilot. Failure would be evident in this case: an employee's old local PIN cannot unlock a fresh replacement laptop as if it were the same credential.
Incorrect Answers
A:The proposed observation checks the different entra password protection on premises scenario. Even a successful test would not establish the requested outcome here: enroll a test device and confirm a user-bound key and approved local biometric/PIN unlock path works.
C:The proposed observation checks the different certificate-based authentication scenario. Even a successful test would not establish the requested outcome here: enroll a test device and confirm a user-bound key and approved local biometric/PIN unlock path works.
D:The proposed observation checks the different microsoft entra kerberos for hybrid authentication scenario. Even a successful test would not establish the requested outcome here: enroll a test device and confirm a user-bound key and approved local biometric/PIN unlock path works.
Question 152
An employee's old local PIN cannot unlock a fresh replacement laptop as if it were the same credential. Which root cause best explains the described result rather than merely treating its symptoms?
- A generic Require multifactor authentication control was used instead of the appropriate authentication strength.
- Windows Hello for Business keys are bound to a user/device context rather than portable reusable PIN credentials.
- The passkey authentication method is not enabled or the pilot group is excluded from its policy.
- Certificate user binding or trusted issuer configuration does not align with the presented credential.
Explanation
Correct Answer
B:Windows Hello for Business keys are bound to a user/device context rather than portable reusable PIN credentials. This is the causal explanation of the observed behavior: an employee's old local PIN cannot unlock a fresh replacement laptop as if it were the same credential. Address the underlying mechanism with: deploy a supported Windows Hello for Business policy and ensure identity/device prerequisites are met for the pilot. Then confirm: enroll a test device and confirm a user-bound key and approved local biometric/PIN unlock path works.
Incorrect Answers
A: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; windows Hello for Business keys are bound to a user/device context rather than portable reusable PIN credentials.
C:This diagnosis fits a separate passkey fido2 registration policy incident: Users possess compatible keys but registration is blocked before key attestation starts. It does not explain this case's observed failure; windows Hello for Business keys are bound to a user/device context rather than portable reusable PIN credentials.
D:This diagnosis fits a separate certificate-based authentication incident: A valid smart-card certificate fails because Entra cannot map its certificate identity to the intended cloud user. It does not explain this case's observed failure; windows Hello for Business keys are bound to a user/device context rather than portable reusable PIN credentials.
Question 153
Company Windows devices should use per-device, key-based Windows Hello for Business sign-in rather than a shared reusable PIN across accounts. Select TWO complementary decisions: the correct technical implementation and the ongoing preventive control. Evidence-only tests and controls for a different scenario are not substitutes for those two responsibilities.
- Maintain secure recovery and device replacement processes without copying Hello key material across devices.
- Deploy a supported Windows Hello for Business policy and ensure identity/device prerequisites are met for the pilot.
- Configure Microsoft Entra certificate-based authentication with appropriate trust chain, user binding and policy scope.
- Test real device enrollment duration and prepare an authorized recovery TAP path before large deployments.
- Configure Entra Kerberos for an unrelated application but leave Windows Hello for Business enrollment disabled on the company Windows devices.
Explanation
Correct Answers
A:Maintain secure recovery and device replacement processes without copying Hello key material across devices. This reduces future drift after the initial control is deployed: deploy a supported Windows Hello for Business policy and ensure identity/device prerequisites are met for the pilot. Recheck the actual behavior with: enroll a test device and confirm a user-bound key and approved local biometric/PIN unlock path works.
B: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
C: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 windows hello for business enrollment change: deploy a supported Windows Hello for Business policy and ensure identity/device prerequisites are met for the pilot.
D:This control manages future single-use tap enrollment timing drift, but it does not reduce the continuing exposure in the described windows hello for business enrollment case. The correct safeguard is: maintain secure recovery and device replacement processes without copying Hello key material across devices.
E:A cloud Kerberos integration to a different resource does not create device-bound Hello credentials or meet the stated Windows sign-in requirement.
Question 154
Security discovers an employee cloud identity is compromised and needs to prevent new sign-ins while invalidating existing refresh sessions. Which proposed configuration or implementation directly meets the stated requirement?
- Deploy a supported Windows Hello for Business policy and ensure identity/device prerequisites are met for the pilot.
- Block the user from sign-in and revoke sign-in sessions or refresh tokens using supported Entra controls, then review application-specific session behavior.
- Apply a Conditional Access authentication strength that requires supported phishing-resistant methods to the intended privileged app and administrators.
- Enable SSPR for the intended eligible users and configure authentication methods and registration requirements.
Explanation
Correct Answer
B:Block the user from sign-in and revoke sign-in sessions or refresh tokens using supported Entra controls, then review application-specific session behavior. The solution acts at the intended identity, policy or application scope. A successful result is testable: attempt a new sign-in and test a previously issued refresh token after revocation while recording any access-token limitations. The competing configuration error is: disabling the account and revoking refresh sessions do not guarantee every previously issued bearer access token is immediately rejected by every app.
Incorrect Answers
A: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 disable compromised account and sessions change: block the user from sign-in and revoke sign-in sessions or refresh tokens using supported Entra controls, then review application-specific session behavior.
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 disable compromised account and sessions change: block the user from sign-in and revoke sign-in sessions or refresh tokens using supported Entra controls, then review application-specific session behavior.
D:That action implements the separate sspr user eligibility decision. It is appropriate when a helpdesk wants nonadmin employees to reset forgotten passwords by self-service, using approved verification methods, while high-privilege accounts use distinct controls. The present case instead requires the specific disable compromised account and sessions change: block the user from sign-in and revoke sign-in sessions or refresh tokens using supported Entra controls, then review application-specific session behavior.
Question 155
Security discovers an employee cloud identity is compromised and needs to prevent new sign-ins while invalidating existing refresh sessions. The proposed change is: Block the user from sign-in and revoke sign-in sessions or refresh tokens using supported Entra controls, then review application-specific session behavior. 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.
- Test password reset for an included employee and exclusion for an out-of-scope account.
- Attempt sign-in using a mapped certificate and confirm the resulting authentication method in the sign-in details.
- Attempt the portal with SMS MFA and with a registered FIDO2 passkey to verify only the qualifying method succeeds.
Explanation
Correct Answer
A:Attempt a new sign-in and test a previously issued refresh token after revocation while recording any access-token limitations. This directly tests the effective outcome, not merely that a configuration exists. It establishes whether the intended change works: block the user from sign-in and revoke sign-in sessions or refresh tokens using supported Entra controls, then review application-specific session behavior. Failure would be evident in this case: a blocked user cannot start a new sign-in but an already issued access token still works temporarily in an app.
Incorrect Answers
B:The proposed observation checks the different sspr user eligibility scenario. Even a successful test would not establish the requested outcome here: attempt a new sign-in and test a previously issued refresh token after revocation while recording any access-token limitations.
C:The proposed observation checks the different certificate-based authentication scenario. Even a successful test would not establish the requested outcome here: attempt a new sign-in and test a previously issued refresh token after revocation while recording any access-token limitations.
D:The proposed observation checks the different phishing-resistant authentication strength scenario. Even a successful test would not establish the requested outcome here: attempt a new sign-in and test a previously issued refresh token after revocation while recording any access-token limitations.
Question 156
A blocked user cannot start a new sign-in but an already issued access token still works temporarily in an app. 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.
- The self-service password reset policy scope excludes the user or is disabled.
- Certificate user binding or trusted issuer configuration does not align with the presented credential.
Explanation
Correct Answer
A:Disabling the account and revoking refresh sessions do not guarantee every previously issued bearer access token is immediately rejected by every app. This is the causal explanation of the observed behavior: a blocked user cannot start a new sign-in but an already issued access token still works temporarily in an app. Address the underlying mechanism with: block the user from sign-in and revoke sign-in sessions or refresh tokens using supported Entra controls, then review application-specific session behavior. Then confirm: attempt a new sign-in and test a previously issued refresh token after revocation while recording any access-token limitations.
Incorrect Answers
B:This diagnosis fits a separate passkey fido2 registration policy incident: Users possess compatible keys but registration is blocked before key attestation starts. It does not explain this case's observed failure; disabling the account and revoking refresh sessions do not guarantee every previously issued bearer access token is immediately rejected by every app.
C:This diagnosis fits a separate sspr user eligibility incident: A user registered methods but sees that password reset isn't enabled for their account. It does not explain this case's observed failure; disabling the account and revoking refresh sessions do not guarantee every previously issued bearer access token is immediately rejected by every app.
D:This diagnosis fits a separate certificate-based authentication incident: A valid smart-card certificate fails because Entra cannot map its certificate identity to the intended cloud user. It does not explain this case's observed failure; disabling the account and revoking refresh sessions do not guarantee every previously issued bearer access token is immediately rejected by every app.
Question 157
Security discovers an employee cloud identity is compromised and needs to prevent new sign-ins while invalidating existing refresh sessions. The initial implementation works. Which continuing control most directly prevents the same failure or drift from recurring?
- Restrict approved authentication-key types and validate registration policies when expanding to new groups.
- 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.
- Test ticket acquisition and on-premises connectivity when modernizing hybrid sign-in methods.
Explanation
Correct Answer
B:Coordinate app revocation and Continuous Access Evaluation behavior and monitor remaining token exposure. This reduces future drift after the initial control is deployed: block the user from sign-in and revoke sign-in sessions or refresh tokens using supported Entra controls, then review application-specific session behavior. Recheck the actual behavior with: attempt a new sign-in and test a previously issued refresh token after revocation while recording any access-token limitations.
Incorrect Answers
A:This control manages future passkey fido2 registration policy drift, but it does not reduce the continuing exposure in the described disable compromised account and sessions case. The correct safeguard is: coordinate app revocation and Continuous Access Evaluation behavior and monitor remaining token exposure.
C:This control manages future certificate-based authentication drift, but it does not reduce the continuing exposure in the described disable compromised account and sessions case. The correct safeguard is: coordinate app revocation and Continuous Access Evaluation behavior and monitor remaining token exposure.
D:This control manages future microsoft entra kerberos for hybrid authentication drift, but it does not reduce the continuing exposure in the described disable compromised account and sessions case. The correct safeguard is: coordinate app revocation and Continuous Access Evaluation behavior and monitor remaining token exposure.
Question 158
An enterprise wants its prohibited company-specific password terms enforced during on-premises AD DS password changes for synchronized users. Which proposed configuration or implementation directly meets the stated requirement?
- Configure Microsoft Entra certificate-based authentication with appropriate trust chain, user binding and policy scope.
- Deploy Microsoft Entra Password Protection proxy and DC agents with the supported tenant configuration and audited banned-password policy.
- 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.
Explanation
Correct Answer
B:Deploy Microsoft Entra Password Protection proxy and DC agents with the supported tenant configuration and audited banned-password policy. The solution acts at the intended identity, policy or application scope. A successful result is testable: change a test AD DS password to an intentionally prohibited company term and confirm the expected rejection and logs. The competing configuration error is: the on-premises password protection agents or enforcement configuration have not been deployed or activated.
Incorrect Answers
A: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 entra password protection on premises change: deploy Microsoft Entra Password Protection proxy and DC agents with the supported tenant configuration and audited banned-password policy.

- Change a test AD DS password to an intentionally prohibited company term and confirm the expected rejection and logs.
- Confirm the user signs in during TAP validity, registers a passkey and then authenticates with the new passkey.
Explanation
Correct Answer
C:Change a test AD DS password to an intentionally prohibited company term and confirm the expected rejection and logs. This directly tests the effective outcome, not merely that a configuration exists. It establishes whether the intended change works: deploy Microsoft Entra Password Protection proxy and DC agents with the supported tenant configuration and audited banned-password policy. Failure would be evident in this case: a prohibited word is rejected by cloud password changes but still accepted by on-premises AD DS domain controllers.
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: change a test AD DS password to an intentionally prohibited company term and confirm the expected rejection and logs.
B:The proposed observation checks the different sspr user eligibility scenario. Even a successful test would not establish the requested outcome here: change a test AD DS password to an intentionally prohibited company term and confirm the expected rejection and logs.
D:The proposed observation checks the different temporary access pass bootstrap scenario. Even a successful test would not establish the requested outcome here: change a test AD DS password to an intentionally prohibited company term and confirm the expected rejection and logs.
Question 160
A prohibited word is rejected by cloud password changes but still accepted by on-premises AD DS domain controllers. 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.
- Certificate user binding or trusted issuer configuration does not align with the presented credential.
- The self-service password reset policy scope excludes the user or is disabled.
- The Entra Kerberos server/trust or device prerequisite is incomplete despite successful cloud authentication.
Explanation
Correct Answer
A:The on-premises password protection agents or enforcement configuration have not been deployed or activated. This is the causal explanation of the observed behavior: a prohibited word is rejected by cloud password changes but still accepted by on-premises AD DS domain controllers. Address the underlying mechanism with: deploy Microsoft Entra Password Protection proxy and DC agents with the supported tenant configuration and audited banned-password policy. Then confirm: change a test AD DS password to an intentionally prohibited company term and confirm the expected rejection and logs.
