Microsoft SC-900 Practice Test 19

Question 180

Following a disaster recovery exercise at a logistics company, the IT operations director has to defend a design against oversimplified assumptions. The requirement is: A security team wants to limit which sign-in methods different user groups can register. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?

  1. Assuming group membership bypasses all resource-level access checks.
  2. Assuming every Entra tenant requires on-premises Active Directory deployment.
  3. Assuming an Entra user administrator role automatically grants owner permissions to every Azure subscription.
  4. Assuming any user may self-enable every authentication method regardless of tenant policy.

Explanation

Correct Answer

D:

Assuming any user may self-enable every authentication method regardless of tenant policy. This belief conflicts with this control principle: Authentication method availability and targeting should be governed centrally for the tenant. The appropriate response instead is: Configure an appropriate Entra authentication methods policy and group targeting.

Incorrect Answers

A:

Assuming group membership bypasses all resource-level access checks. That caution concerns groups for access; the specific misconception here is: Assuming any user may self-enable every authentication method regardless of tenant policy.

B:

Assuming every Entra tenant requires on-premises Active Directory deployment. That caution concerns cloud-only identity; the specific misconception here is: Assuming any user may self-enable every authentication method regardless of tenant policy.

C:

Assuming an Entra user administrator role automatically grants owner permissions to every Azure subscription. That caution concerns azure rbac compared with entra roles; the specific misconception here is: Assuming any user may self-enable every authentication method regardless of tenant policy.

Question 181

During a cloud governance workshop at a managed services company, the risk manager records this concrete requirement: A sensitive app must require phishing-resistant authentication instead of accepting any second factor. The solution must address this requirement directly, without replacing unrelated controls. Which primary response BEST meets the requirement?

  1. Use a service principal representing the application in the tenant and grant only required permissions.
  2. Apply an authentication strength requirement through a suitable Conditional Access policy.
  3. Define a Conditional Access policy with relevant assignments, conditions, and grant or block controls.
  4. Use Microsoft Entra entitlement management access packages with policies, approval, and expiration rules.

Explanation

Correct Answer

B:

Apply an authentication strength requirement through a suitable Conditional Access policy. Authentication strengths can specify which combinations of methods satisfy a protected access requirement. To verify, review sign-in details to ensure a permitted phishing-resistant method satisfied the strength.

Incorrect Answers

A:

Use a service principal representing the application in the tenant and grant only required permissions. That addresses a different task: an application needs a security identity to request tokens and access a protected API. The present requirement concerns authentication strength.

C:

Define a Conditional Access policy with relevant assignments, conditions, and grant or block controls. That addresses a different task: access to an app should depend on identity, device compliance, location, or sign-in risk. The present requirement concerns authentication strength.

D:

Use Microsoft Entra entitlement management access packages with policies, approval, and expiration rules. That addresses a different task: a project team must package multiple group and application entitlements for controlled requests and expiry. The present requirement concerns authentication strength.

Question 182

During a cloud governance workshop at a managed services company, the risk manager records this concrete requirement: A sensitive app must require phishing-resistant authentication instead of accepting any second factor. The solution must address this requirement directly, without replacing unrelated controls. The team implements the following response: Apply an authentication strength requirement through a suitable Conditional Access policy. Which evidence BEST verifies that the action met its stated purpose?

  1. Check user and application objects and successful identity-provider sign-ins in the Entra tenant.
  2. Verify users are cloud-managed and can sign into configured cloud applications.
  3. Review sign-in details to ensure a permitted phishing-resistant method satisfied the strength.
  4. Check synchronized objects, attribute flows, and authentication behavior across on-premises and cloud environments.

Explanation

Correct Answer

C:

Review sign-in details to ensure a permitted phishing-resistant method satisfied the strength. Authentication strengths can specify which combinations of methods satisfy a protected access requirement.

Incorrect Answers

A:

Check user and application objects and successful identity-provider sign-ins in the Entra tenant. This would test microsoft entra id cloud identity, whereas the required evidence is: Review sign-in details to ensure a permitted phishing-resistant method satisfied the strength.

B:

Verify users are cloud-managed and can sign into configured cloud applications. This would test cloud-only identity, whereas the required evidence is: Review sign-in details to ensure a permitted phishing-resistant method satisfied the strength.

D:

Check synchronized objects, attribute flows, and authentication behavior across on-premises and cloud environments. This would test hybrid identity, whereas the required evidence is: Review sign-in details to ensure a permitted phishing-resistant method satisfied the strength.

Question 183

Following an internal access audit at a retail payments business, the technology auditor has to defend a design against oversimplified assumptions. The requirement is: A sensitive app must require phishing-resistant authentication instead of accepting any second factor. The review is limited to the control and concept described by this requirement. Which security, identity, or compliance principle MOST directly explains the appropriate approach?

  1. Device compliance can be an access condition when supported and configured.
  2. Risk-aware access decisions adapt protections to current identity threat indicators.
  3. A Conditional Access block decision denies an access request when policy conditions match.
  4. Authentication strengths can specify which combinations of methods satisfy a protected access requirement.

Explanation

Correct Answer

D:

Authentication strengths can specify which combinations of methods satisfy a protected access requirement. It explains why the selected measure—Apply an authentication strength requirement through a suitable Conditional Access policy—fits the specific requirement. It should be verified by checking: Review sign-in details to ensure a permitted phishing-resistant method satisfied the strength.

Incorrect Answers

A:

Device compliance can be an access condition when supported and configured. This describes conditional access device compliance; the governing concept here is: Authentication strengths can specify which combinations of methods satisfy a protected access requirement.

B:

Risk-aware access decisions adapt protections to current identity threat indicators. This describes risk-based access control; the governing concept here is: Authentication strengths can specify which combinations of methods satisfy a protected access requirement.

C:

A Conditional Access block decision denies an access request when policy conditions match. This describes conditional access block; the governing concept here is: Authentication strengths can specify which combinations of methods satisfy a protected access requirement.

Question 184

Following an internal access audit at a retail payments business, the technology auditor has to defend a design against oversimplified assumptions. The requirement is: A sensitive app must require phishing-resistant authentication instead of accepting any second factor. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?

  1. Assuming a generic MFA grant rule is identical to a phishing-resistant authentication-strength requirement.
  2. Assuming an application should authenticate by sharing an administrator's human password.
  3. Treating an internal employee's user account as the same object type as an application service principal.
  4. Assuming every eligible user can silently activate any role without activation settings.

Explanation

Correct Answer

A:

Assuming a generic MFA grant rule is identical to a phishing-resistant authentication-strength requirement. This belief conflicts with this control principle: Authentication strengths can specify which combinations of methods satisfy a protected access requirement. The appropriate response instead is: Apply an authentication strength requirement through a suitable Conditional Access policy.

Incorrect Answers

B:

Assuming an application should authenticate by sharing an administrator's human password. That caution concerns service principal; the specific misconception here is: Assuming a generic MFA grant rule is identical to a phishing-resistant authentication-strength requirement.

C:

Treating an internal employee's user account as the same object type as an application service principal. That caution concerns member user identity; the specific misconception here is: Assuming a generic MFA grant rule is identical to a phishing-resistant authentication-strength requirement.

D:

Assuming every eligible user can silently activate any role without activation settings. That caution concerns pim approval and activation; the specific misconception here is: Assuming a generic MFA grant rule is identical to a phishing-resistant authentication-strength requirement.

Question 185

During a vendor assurance review at a national retailer, the application administrator records this concrete requirement: An identity analyst needs to troubleshoot why a user was challenged or denied access. The solution must address this requirement directly, without replacing unrelated controls. Which primary response BEST meets the requirement?

  1. Use supported risk signals with Conditional Access to require remediation or block appropriate attempts.
  2. Use Microsoft Entra Lifecycle Workflows where appropriate to automate defined identity lifecycle actions.
  3. Review Microsoft Entra sign-in logs including status, applied policy, and authentication details.
  4. Create cloud-managed Microsoft Entra users and groups without introducing an unnecessary domain controller.

Explanation

Correct Answer

C:

Review Microsoft Entra sign-in logs including status, applied policy, and authentication details. Sign-in logs provide evidence of authentication and access policy evaluations. To verify, find the sign-in event and correlate time, user, application, conditions, and policy result.

Incorrect Answers

A:

Use supported risk signals with Conditional Access to require remediation or block appropriate attempts. That addresses a different task: the organization wants extra protection for sign-ins that the identity risk system marks suspicious. The present requirement concerns sign-in logs.

B:

Use Microsoft Entra Lifecycle Workflows where appropriate to automate defined identity lifecycle actions. That addresses a different task: joiner, mover, and leaver events need predictable identity-management tasks. The present requirement concerns sign-in logs.

D:

Create cloud-managed Microsoft Entra users and groups without introducing an unnecessary domain controller. That addresses a different task: a new business has no on-premises directory and wants to manage all workforce accounts in the cloud. The present requirement concerns sign-in logs.

Question 186

During a vendor assurance review at a national retailer, the application administrator records this concrete requirement: An identity analyst needs to troubleshoot why a user was challenged or denied access. The solution must address this requirement directly, without replacing unrelated controls. The team implements the following response: Review Microsoft Entra sign-in logs including status, applied policy, and authentication details. Which evidence BEST verifies that the action met its stated purpose?

  1. Inspect role assignments at the subscription or resource and compare them with directory roles.
  2. Review risk detections and affected identities, then confirm the chosen remediation action.
  3. Test allowed and disallowed location conditions and inspect actual enforcement logs.
  4. Find the sign-in event and correlate time, user, application, conditions, and policy result.

Explanation

Correct Answer

D:

Find the sign-in event and correlate time, user, application, conditions, and policy result. Sign-in logs provide evidence of authentication and access policy evaluations.

Incorrect Answers

A:

Inspect role assignments at the subscription or resource and compare them with directory roles. This would test azure rbac compared with entra roles, whereas the required evidence is: Find the sign-in event and correlate time, user, application, conditions, and policy result.

B:

Review risk detections and affected identities, then confirm the chosen remediation action. This would test microsoft entra id protection, whereas the required evidence is: Find the sign-in event and correlate time, user, application, conditions, and policy result.

C:

Test allowed and disallowed location conditions and inspect actual enforcement logs. This would test conditional access block, whereas the required evidence is: Find the sign-in event and correlate time, user, application, conditions, and policy result.

Question 187

Following a peer architecture review at an international shipping company, the information governance lead has to defend a design against oversimplified assumptions. The requirement is: An identity analyst needs to troubleshoot why a user was challenged or denied access. The review is limited to the control and concept described by this requirement. Which security, identity, or compliance principle MOST directly explains the appropriate approach?

  1. Sign-in logs provide evidence of authentication and access policy evaluations.
  2. Directory groups simplify administration of shared assignments while underlying resource permissions still matter.
  3. Risk-aware access decisions adapt protections to current identity threat indicators.
  4. Cloud-only identities can be managed entirely in Microsoft Entra without on-premises directory synchronization.

Explanation

Correct Answer

A:

Sign-in logs provide evidence of authentication and access policy evaluations. It explains why the selected measure—Review Microsoft Entra sign-in logs including status, applied policy, and authentication details—fits the specific requirement. It should be verified by checking: Find the sign-in event and correlate time, user, application, conditions, and policy result.

Incorrect Answers

B:

Directory groups simplify administration of shared assignments while underlying resource permissions still matter. This describes groups for access; the governing concept here is: Sign-in logs provide evidence of authentication and access policy evaluations.

C:

Risk-aware access decisions adapt protections to current identity threat indicators. This describes risk-based access control; the governing concept here is: Sign-in logs provide evidence of authentication and access policy evaluations.

D:

Cloud-only identities can be managed entirely in Microsoft Entra without on-premises directory synchronization. This describes cloud-only identity; the governing concept here is: Sign-in logs provide evidence of authentication and access policy evaluations.

Question 188

Following a peer architecture review at an international shipping company, the information governance lead has to defend a design against oversimplified assumptions. The requirement is: An identity analyst needs to troubleshoot why a user was challenged or denied access. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?

  1. Assuming Entra ID itself inspects all virtual-network packets like a network security appliance.
  2. Assuming a directory user profile alone explains each failed sign-in and applied policy decision.
  3. Assuming a successful sign-in always means the account has no identity risk.
  4. Assuming managed identity means every reachable Azure service automatically permits the workload access.

Explanation

Correct Answer

B:

Assuming a directory user profile alone explains each failed sign-in and applied policy decision. This belief conflicts with this control principle: Sign-in logs provide evidence of authentication and access policy evaluations. The appropriate response instead is: Review Microsoft Entra sign-in logs including status, applied policy, and authentication details.

Incorrect Answers

A:

Assuming Entra ID itself inspects all virtual-network packets like a network security appliance. That caution concerns microsoft entra id cloud identity; the specific misconception here is: Assuming a directory user profile alone explains each failed sign-in and applied policy decision.

C:

Assuming a successful sign-in always means the account has no identity risk. That caution concerns microsoft entra id protection; the specific misconception here is: Assuming a directory user profile alone explains each failed sign-in and applied policy decision.

D:

Assuming managed identity means every reachable Azure service automatically permits the workload access. That caution concerns managed identity; the specific misconception here is: Assuming a directory user profile alone explains each failed sign-in and applied policy decision.

Question 189

During an infrastructure modernization effort at a financial software company, the incident responder records this concrete requirement: A tenant sees old basic-authentication clients that cannot satisfy modern controls reliably. The solution must address this requirement directly, without replacing unrelated controls. Which primary response BEST meets the requirement?

  1. Assign an appropriate narrower Microsoft Entra administrative role at the justified scope.
  2. Configure PIM activation settings with approval and appropriate duration for the target role.
  3. Assign suitable access to a managed Entra group rather than maintaining each user assignment individually.
  4. Identify and block unwanted legacy authentication flows, migrating clients to modern authentication.

Explanation

Correct Answer

D:

Identify and block unwanted legacy authentication flows, migrating clients to modern authentication. Older authentication protocols can bypass or limit modern conditional identity protections. To verify, review sign-in logs for legacy protocol attempts and verify the block policy outcome.

Incorrect Answers

A:

Assign an appropriate narrower Microsoft Entra administrative role at the justified scope. That addresses a different task: a junior admin needs to manage users but should not receive global tenant administration. The present requirement concerns legacy authentication.

B:

Configure PIM activation settings with approval and appropriate duration for the target role. That addresses a different task: a high-impact role must require business approval before a user can elevate privilege. The present requirement concerns legacy authentication.

C:

Assign suitable access to a managed Entra group rather than maintaining each user assignment individually. That addresses a different task: an administrator repeatedly assigns the same application access to a changing staff team. The present requirement concerns legacy authentication.

Question 190

During an infrastructure modernization effort at a financial software company, the incident responder records this concrete requirement: A tenant sees old basic-authentication clients that cannot satisfy modern controls reliably. The solution must address this requirement directly, without replacing unrelated controls. The team implements the following response: Identify and block unwanted legacy authentication flows, migrating clients to modern authentication. Which evidence BEST verifies that the action met its stated purpose?

  1. Review sign-in logs for legacy protocol attempts and verify the block policy outcome.
  2. Inspect role assignments and test which administrative tasks the assignee can perform.
  3. Verify users are cloud-managed and can sign into configured cloud applications.
  4. Review risk detections and affected identities, then confirm the chosen remediation action.

Explanation

Correct Answer

A:

Review sign-in logs for legacy protocol attempts and verify the block policy outcome. Older authentication protocols can bypass or limit modern conditional identity protections.

Incorrect Answers

B:

Inspect role assignments and test which administrative tasks the assignee can perform. This would test entra directory roles, whereas the required evidence is: Review sign-in logs for legacy protocol attempts and verify the block policy outcome.

C:

Verify users are cloud-managed and can sign into configured cloud applications. This would test cloud-only identity, whereas the required evidence is: Review sign-in logs for legacy protocol attempts and verify the block policy outcome.

D:

Review risk detections and affected identities, then confirm the chosen remediation action. This would test microsoft entra id protection, whereas the required evidence is: Review sign-in logs for legacy protocol attempts and verify the block policy outcome.
