Microsoft SC-300 Practice Test 16

Question 150

The deployment was intended to satisfy: A sync administrator needs to stop accidental mass deletion of cloud users caused by an incorrect on-prem OU filter. During testing, this happened: Hundreds of previously synchronized users vanish after a mistaken filter edit. Which configuration defect best explains the failure?

  1. All pass-through authentication agents are unavailable or unhealthy
  2. The second forest's agent or provisioning configuration was never activated
  3. Password synchronization is disabled or has not completed after the AD password change
  4. Accidental-deletion safeguards were disabled or the deletion threshold was inappropriately raised

Explanation

Correct Answer

D:

Correct diagnosis. Accidental-deletion safeguards were disabled or the deletion threshold was inappropriately raised. This fault explains the observed failure: Hundreds of previously synchronized users vanish after a mistaken filter edit. The intended configuration would instead be: Review staging/export deletion thresholds and accidental-delete protection before approving large deletion exports.

Incorrect Answers

A:

All pass-through authentication agents are unavailable or unhealthy. The reported symptom instead has this cause: Accidental-deletion safeguards were disabled or the deletion threshold was inappropriately raised. The corrective action is: Review staging/export deletion thresholds and accidental-delete protection before approving large deletion exports.

B:

The second forest's agent or provisioning configuration was never activated. The reported symptom instead has this cause: Accidental-deletion safeguards were disabled or the deletion threshold was inappropriately raised. The corrective action is: Review staging/export deletion thresholds and accidental-delete protection before approving large deletion exports.

C:

Password synchronization is disabled or has not completed after the AD password change. The reported symptom instead has this cause: Accidental-deletion safeguards were disabled or the deletion threshold was inappropriately raised. The corrective action is: Review staging/export deletion thresholds and accidental-delete protection before approving large deletion exports.

Question 151

An identity engineer has two independent tasks. Task 1: A new remote employee has no registered strong factor and the helpdesk must securely bootstrap the first passkey registration without providing a permanent password. Task 2: A helpdesk must roll out self-service password reset for hybrid users and require two authentication methods for reset verification. Which TWO configuration changes jointly meet both tasks?

  1. Scope authentication method and registration campaign targets using correct include/exclude groups and keep emergency account access independent
  2. Enable Microsoft Entra password protection using a custom banned password list, with on-prem agents for AD DS coverage where needed
  3. Enable SSPR for the selected users with two-method verification and required hybrid writeback configuration
  4. Issue a short-lived scoped Temporary Access Pass under the approved authentication-method policy, and complete device/passkey registration within ten minutes of a single-use TAP sign-in or use a suitably governed multiuse TAP
  5. Configure an authentication methods registration campaign with correct eligibility and snooze behavior

Explanation

Correct Answers

C:

Correct for task 2. Enable SSPR for the selected users with two-method verification and required hybrid writeback configuration. This addresses the independent second requirement: A helpdesk must roll out self-service password reset for hybrid users and require two authentication methods for reset verification. Verify it by checking: An eligible hybrid test user completes two-method verification, changes the password, and signs in to AD DS using the new password.

D:

Correct for task 1. Issue a short-lived scoped Temporary Access Pass under the approved authentication-method policy, and complete device/passkey registration within ten minutes of a single-use TAP sign-in or use a suitably governed multiuse TAP. This directly addresses the first requirement: A new remote employee has no registered strong factor and the helpdesk must securely bootstrap the first passkey registration without providing a permanent password. Verify it by checking: A targeted employee completes registered passkey onboarding in the permitted single-use TAP registration window, and a consumed or expired pass cannot be reused to start another session.

Incorrect Answers

A:

The emergency account remains in the campaign's included population without the intended exclusion. To satisfy task 1, use: Issue a short-lived scoped Temporary Access Pass under the approved authentication-method policy, and complete device/passkey registration within ten minutes of a single-use TAP sign-in or use a suitably governed multiuse TAP. For task 2, use: Enable SSPR for the selected users with two-method verification and required hybrid writeback configuration.

B:

The banned password list exists but Enforce custom list is disabled for the applicable scope. To satisfy task 1, use: Issue a short-lived scoped Temporary Access Pass under the approved authentication-method policy, and complete device/passkey registration within ten minutes of a single-use TAP sign-in or use a suitably governed multiuse TAP. For task 2, use: Enable SSPR for the selected users with two-method verification and required hybrid writeback configuration.

E:

The registration campaign targets a different method or excludes the intended staff group. To satisfy task 1, use: Issue a short-lived scoped Temporary Access Pass under the approved authentication-method policy, and complete device/passkey registration within ten minutes of a single-use TAP sign-in or use a suitably governed multiuse TAP. For task 2, use: Enable SSPR for the selected users with two-method verification and required hybrid writeback configuration.

Question 152

The owner wants independent acceptance evidence after the team chose: Issue a short-lived scoped Temporary Access Pass under the approved authentication-method policy, and complete device/passkey registration within ten minutes of a single-use TAP sign-in or use a suitably governed multiuse TAP. It was meant to solve: A new remote employee has no registered strong factor and the helpdesk must securely bootstrap the first passkey registration without providing a permanent password. Which result demonstrates success?

  1. An approved device-bound passkey satisfies the target strength while SMS alone and a disallowed passkey provider fail the intended restriction
  2. A targeted employee completes registered passkey onboarding in the permitted single-use TAP registration window, and a consumed or expired pass cannot be reused to start another session
  3. An eligible hybrid test user completes two-method verification, changes the password, and signs in to AD DS using the new password
  4. New authentication fails and a qualifying CAE-aware client loses protected resource access within the documented propagation window; unsupported sessions are explicitly monitored

Explanation

Correct Answer

B:

Correct acceptance check. A targeted employee completes registered passkey onboarding in the permitted single-use TAP registration window, and a consumed or expired pass cannot be reused to start another session. This tests the intended access or synchronization boundary instead of merely checking that a setting exists.

Incorrect Answers

A:

Even if allowing approved device-bound FIDO2 passkey providers or attested security-key models through the authentication-method policy succeeds, this does not prove the required identity-control outcome. The decisive check is: A targeted employee completes registered passkey onboarding in the permitted single-use TAP registration window, and a consumed or expired pass cannot be reused to start another session.

C:

Even if enabling SSPR for the selected users with two-method verification succeeds, this does not prove the required identity-control outcome. The decisive check is: A targeted employee completes registered passkey onboarding in the permitted single-use TAP registration window, and a consumed or expired pass cannot be reused to start another session.

D:

Even if blocking the compromised account succeeds, this does not prove the required identity-control outcome. The decisive check is: A targeted employee completes registered passkey onboarding in the permitted single-use TAP registration window, and a consumed or expired pass cannot be reused to start another session.

Question 153

The deployment owner asks why this identity requirement failed: A new remote employee has no registered strong factor and the helpdesk must securely bootstrap the first passkey registration without providing a permanent password. The test shows: The enrollment portal denies the temporary bootstrap credential before any passkey is created. Which fault is the best diagnosis?

  1. The banned password list exists but Enforce custom list is disabled for the applicable scope
  2. The TAP is out of scope, consumed or expired, or the single-use TAP registration proceeds beyond its permitted authentication window
  3. The response did not block new account sign-in or revoke refresh sessions, and the application might not participate in CAE event enforcement
  4. SSPR was enabled without the supported password writeback path to on-premises AD

Explanation

Correct Answer

B:

Correct diagnosis. The TAP is out of scope, consumed or expired, or the single-use TAP registration proceeds beyond its permitted authentication window. This fault explains the observed failure: The enrollment portal denies the temporary bootstrap credential before any passkey is created. The intended configuration would instead be: Issue a short-lived scoped Temporary Access Pass under the approved authentication-method policy, and complete device/passkey registration within ten minutes of a single-use TAP sign-in or use a suitably governed multiuse TAP.

Incorrect Answers

A:

The banned password list exists but Enforce custom list is disabled for the applicable scope. The reported symptom instead has this cause: The TAP is out of scope, consumed or expired, or the single-use TAP registration proceeds beyond its permitted authentication window. The corrective action is: Issue a short-lived scoped Temporary Access Pass under the approved authentication-method policy, and complete device/passkey registration within ten minutes of a single-use TAP sign-in or use a suitably governed multiuse TAP.

The reported symptom instead has this cause: The TAP is out of scope, consumed or expired, or the single-use TAP registration proceeds beyond its permitted authentication window. The corrective action is: Issue a short-lived scoped Temporary Access Pass under the approved authentication-method policy, and complete device/passkey registration within ten minutes of a single-use TAP sign-in or use a suitably governed multiuse TAP.

Question 154

Select the most appropriate first configuration decision for this scenario: A regulated workforce must use device-bound phishing-resistant authentication rather than just an SMS code.

  1. Allow approved device-bound FIDO2 passkey providers or attested security-key models through the authentication-method policy and enforce an appropriate phishing-resistant Conditional Access strength
  2. Configure Microsoft Entra certificate-based authentication with the trusted CA and supported username binding
  3. Examine Microsoft Entra sign-in authentication details and method records for the pilot sign-in
  4. Set certificate authentication binding and authentication strength policies according to supported Entra CBA configuration

Explanation

Correct Answer

A:

Correct implementation. Allow approved device-bound FIDO2 passkey providers or attested security-key models through the authentication-method policy and enforce an appropriate phishing-resistant Conditional Access strength. It meets the stated requirement: A regulated workforce must use device-bound phishing-resistant authentication rather than just an SMS code. Acceptance evidence is: An approved device-bound passkey satisfies the target strength while SMS alone and a disallowed passkey provider fail the intended restriction.

Incorrect Answers

B:

The sign-in certificate's issuer is not configured as trusted or its user binding does not resolve. That condition is not the problem here: Only generic multifactor authentication is required, without a device-bound provider restriction where the policy requires one. The targeted implementation is: Allow approved device-bound FIDO2 passkey providers or attested security-key models through the authentication-method policy and enforce an appropriate phishing-resistant Conditional Access strength.

C:

Investigators inspected only the top-level Conditional Access success field and not authentication details. That condition is not the problem here: Only generic multifactor authentication is required, without a device-bound provider restriction where the policy requires one. The targeted implementation is: Allow approved device-bound FIDO2 passkey providers or attested security-key models through the authentication-method policy and enforce an appropriate phishing-resistant Conditional Access strength.

D:

The binding rule accepts a weak fallback identifier inconsistent with the tenant's mapping policy. That condition is not the problem here: Only generic multifactor authentication is required, without a device-bound provider restriction where the policy requires one. The targeted implementation is: Allow approved device-bound FIDO2 passkey providers or attested security-key models through the authentication-method policy and enforce an appropriate phishing-resistant Conditional Access strength.

Question 155

An operational review checks whether the change “Allow approved device-bound FIDO2 passkey providers or attested security-key models through the authentication-method policy and enforce an appropriate phishing-resistant Conditional Access strength” meets this need: A regulated workforce must use device-bound phishing-resistant authentication rather than just an SMS code. Which finding supports acceptance?

  1. A registered employee signs in using the device-bound Hello key and a PIN on a different device cannot unlock that key
  2. A mapped certificate with approved assurance authenticates; an unapproved mapping or certificate fails
  3. A targeted employee completes registered passkey onboarding in the permitted single-use TAP registration window, and a consumed or expired pass cannot be reused to start another session
  4. An approved device-bound passkey satisfies the target strength while SMS alone and a disallowed passkey provider fail the intended restriction

Explanation

Correct Answer

D:

Correct acceptance check. An approved device-bound passkey satisfies the target strength while SMS alone and a disallowed passkey provider fail the intended restriction. This tests the intended access or synchronization boundary instead of merely checking that a setting exists.

Incorrect Answers

A:

Even if planning Windows Hello for Business with the supported trust/deployment model succeeds, this does not prove the required identity-control outcome. The decisive check is: An approved device-bound passkey satisfies the target strength while SMS alone and a disallowed passkey provider fail the intended restriction.

B:

Even if setting certificate authentication binding succeeds, this does not prove the required identity-control outcome. The decisive check is: An approved device-bound passkey satisfies the target strength while SMS alone and a disallowed passkey provider fail the intended restriction.

C:

Even if issuing a short-lived scoped Temporary Access Pass under the approved authentication-method policy succeeds, this does not prove the required identity-control outcome. The decisive check is: An approved device-bound passkey satisfies the target strength while SMS alone and a disallowed passkey provider fail the intended restriction.

Question 156

The deployment was intended to satisfy: A regulated workforce must use device-bound phishing-resistant authentication rather than just an SMS code. During testing, this happened: A text-message OTP alone satisfies the supposedly phishing-resistant access policy. Which configuration defect best explains the failure?

  1. The sign-in certificate's issuer is not configured as trusted or its user binding does not resolve
  2. The device is not configured for the required Windows Hello for Business provisioning policy
  3. Only generic multifactor authentication is required, without a device-bound provider restriction where the policy requires one
  4. The authentication methods policy targets All users instead of the permitted staff population

Explanation

Correct Answer

C:

Correct diagnosis. Only generic multifactor authentication is required, without a device-bound provider restriction where the policy requires one. This fault explains the observed failure: A text-message OTP alone satisfies the supposedly phishing-resistant access policy. The intended configuration would instead be: Allow approved device-bound FIDO2 passkey providers or attested security-key models through the authentication-method policy and enforce an appropriate phishing-resistant Conditional Access strength.

Incorrect Answers

A:

The sign-in certificate's issuer is not configured as trusted or its user binding does not resolve. The reported symptom instead has this cause: Only generic multifactor authentication is required, without a device-bound provider restriction where the policy requires one. The corrective action is: Allow approved device-bound FIDO2 passkey providers or attested security-key models through the authentication-method policy and enforce an appropriate phishing-resistant Conditional Access strength.

B:

The device is not configured for the required Windows Hello for Business provisioning policy. The reported symptom instead has this cause: Only generic multifactor authentication is required, without a device-bound provider restriction where the policy requires one. The corrective action is: Allow approved device-bound FIDO2 passkey providers or attested security-key models through the authentication-method policy and enforce an appropriate phishing-resistant Conditional Access strength.

D:

The authentication methods policy targets All users instead of the permitted staff population. The reported symptom instead has this cause: Only generic multifactor authentication is required, without a device-bound provider restriction where the policy requires one. The corrective action is: Allow approved device-bound FIDO2 passkey providers or attested security-key models through the authentication-method policy and enforce an appropriate phishing-resistant Conditional Access strength.

Question 157

The security architect is given this constraint: Support agents should offer Microsoft Authenticator notifications only to a permitted population and not to service accounts. Which technical approach meets it without relying on unrelated controls?

  1. Deploy the supported Microsoft Entra Kerberos configuration and ensure joined-device, domain, and service prerequisites are satisfied
  2. Scope the Authenticator method policy to the staff group and exclude workload/service identities as required
  3. Scope authentication method and registration campaign targets using correct include/exclude groups and keep emergency account access independent
  4. Enable Microsoft Entra password protection using a custom banned password list, with on-prem agents for AD DS coverage where needed

Explanation

Correct Answer

B:

Correct implementation. Scope the Authenticator method policy to the staff group and exclude workload/service identities as required. It meets the stated requirement: Support agents should offer Microsoft Authenticator notifications only to a permitted population and not to service accounts. Acceptance evidence is: An enrolled staff pilot can register and use Authenticator; an excluded test principal does not receive the method.

Incorrect Answers

A:

The cloud Kerberos server object or device trust configuration is missing. That condition is not the problem here: The authentication methods policy targets All users instead of the permitted staff population. The targeted implementation is: Scope the Authenticator method policy to the staff group and exclude workload/service identities as required.

C:

The emergency account remains in the campaign's included population without the intended exclusion. That condition is not the problem here: The authentication methods policy targets All users instead of the permitted staff population. The targeted implementation is: Scope the Authenticator method policy to the staff group and exclude workload/service identities as required.

D:

The banned password list exists but Enforce custom list is disabled for the applicable scope. That condition is not the problem here: The authentication methods policy targets All users instead of the permitted staff population. The targeted implementation is: Scope the Authenticator method policy to the staff group and exclude workload/service identities as required.

Question 158

After a deployment under this requirement — Support agents should offer Microsoft Authenticator notifications only to a permitted population and not to service accounts — administrators claim the following solution is in place: Scope the Authenticator method policy to the staff group and exclude workload/service identities as required. Which pilot finding supports that claim?

  1. An enrolled staff pilot can register and use Authenticator; an excluded test principal does not receive the method
  2. A targeted employee completes registered passkey onboarding in the permitted single-use TAP registration window, and a consumed or expired pass cannot be reused to start another session
  3. An eligible hybrid test user completes two-method verification, changes the password, and signs in to AD DS using the new password
  4. Eligible users receive the enrollment prompt according to campaign settings while excluded accounts do not

Explanation

Correct Answer

A:

Correct acceptance check. An enrolled staff pilot can register and use Authenticator; an excluded test principal does not receive the method. This tests the intended access or synchronization boundary instead of merely checking that a setting exists.

Incorrect Answers

B:

Even if issuing a short-lived scoped Temporary Access Pass under the approved authentication-method policy succeeds, this does not prove the required identity-control outcome. The decisive check is: An enrolled staff pilot can register and use Authenticator; an excluded test principal does not receive the method.

C:

Even if enabling SSPR for the selected users with two-method verification succeeds, this does not prove the required identity-control outcome. The decisive check is: An enrolled staff pilot can register and use Authenticator; an excluded test principal does not receive the method.

D:

Even if configuring an authentication methods registration campaign with correct eligibility succeeds, this does not prove the required identity-control outcome. The decisive check is: An enrolled staff pilot can register and use Authenticator; an excluded test principal does not receive the method.

Question 159

An engineer troubleshoots an identity solution for: Support agents should offer Microsoft Authenticator notifications only to a permitted population and not to service accounts. The pilot result is: The excluded test population can register the Authenticator method. What is the most likely relevant fault?

  1. The authentication methods policy targets All users instead of the permitted staff population
  2. The cloud Kerberos server object or device trust configuration is missing
  3. The registration campaign targets a different method or excludes the intended staff group
  4. The device is not configured for the required Windows Hello for Business provisioning policy

Question 160

Which implementation fits the following specific identity problem? A helpdesk must roll out self-service password reset for hybrid users and require two authentication methods for reset verification.

  1. Deploy the supported Microsoft Entra Kerberos configuration and ensure joined-device, domain, and service prerequisites are satisfied
  2. Set certificate authentication binding and authentication strength policies according to supported Entra CBA configuration
  3. Configure an authentication methods registration campaign with correct eligibility and snooze behavior
  4. Enable SSPR for the selected users with two-method verification and required hybrid writeback configuration

Explanation

Correct Answer

D:

Correct implementation. Enable SSPR for the selected users with two-method verification and required hybrid writeback configuration. It meets the stated requirement: A helpdesk must roll out self-service password reset for hybrid users and require two authentication methods for reset verification. Acceptance evidence is: An eligible hybrid test user completes two-method verification, changes the password, and signs in to AD DS using the new password.

Incorrect Answers

A:

The cloud Kerberos server object or device trust configuration is missing. That condition is not the problem here: SSPR was enabled without the supported password writeback path to on-premises AD. The targeted implementation is: Enable SSPR for the selected users with two-method verification and required hybrid writeback configuration.

B:

The binding rule accepts a weak fallback identifier inconsistent with the tenant's mapping policy. That condition is not the problem here: SSPR was enabled without the supported password writeback path to on-premises AD.
