Microsoft SC-900 Practice Test 14

Question 130

During a regulated-workload onboarding at a local government agency, the application administrator records this concrete requirement: An external auditor needs time-bounded access to selected resources without becoming an internal employee. The solution must address this requirement directly, without replacing unrelated controls. The team implements the following response: Invite and govern an external guest identity with explicit resource permissions and review. Which evidence BEST verifies that the action met its stated purpose?

  1. Inspect sign-in report-only results, identify disruptions, and then confirm enabled policy decisions after rollout.
  2. Confirm guest identity type, accepted invitation, resource assignment, and eventual removal or expiration.
  3. Inspect role assignments at the subscription or resource and compare them with directory roles.
  4. Use sign-in policy evaluation and What If analysis to confirm the right users and applications match.

Explanation

Correct Answer

B:

Confirm guest identity type, accepted invitation, resource assignment, and eventual removal or expiration. Guest collaboration supports external identities under receiving-tenant access controls.

Incorrect Answers

A:

Inspect sign-in report-only results, identify disruptions, and then confirm enabled policy decisions after rollout. This would test conditional access report-only, whereas the required evidence is: Confirm guest identity type, accepted invitation, resource assignment, and eventual removal or expiration.

C:

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: Confirm guest identity type, accepted invitation, resource assignment, and eventual removal or expiration.

D:

Use sign-in policy evaluation and What If analysis to confirm the right users and applications match. This would test conditional access signals, whereas the required evidence is: Confirm guest identity type, accepted invitation, resource assignment, and eventual removal or expiration.

Question 131

Following a quarterly control assessment at a city council, the information governance lead has to defend a design against oversimplified assumptions. The requirement is: An external auditor needs time-bounded access to selected resources without becoming an internal employee. 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. Directory roles define delegated administrative capabilities and should follow least privilege.
  2. Device compliance can be an access condition when supported and configured.
  3. Guest collaboration supports external identities under receiving-tenant access controls.
  4. Authentication strengths can specify which combinations of methods satisfy a protected access requirement.

Explanation

Correct Answer

C:

Guest collaboration supports external identities under receiving-tenant access controls. It explains why the selected measure—Invite and govern an external guest identity with explicit resource permissions and review—fits the specific requirement. It should be verified by checking: Confirm guest identity type, accepted invitation, resource assignment, and eventual removal or expiration.

Incorrect Answers

A:

Directory roles define delegated administrative capabilities and should follow least privilege. This describes entra directory roles; the governing concept here is: Guest collaboration supports external identities under receiving-tenant access controls.

B:

Device compliance can be an access condition when supported and configured. This describes conditional access device compliance; the governing concept here is: Guest collaboration supports external identities under receiving-tenant access controls.

D:

Authentication strengths can specify which combinations of methods satisfy a protected access requirement. This describes authentication strength; the governing concept here is: Guest collaboration supports external identities under receiving-tenant access controls.

Question 132

Following a quarterly control assessment at a city council, the information governance lead has to defend a design against oversimplified assumptions. The requirement is: An external auditor needs time-bounded access to selected resources without becoming an internal employee. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?

  1. Assuming an SSPR rollout removes the need to register verification methods or scope eligible users.
  2. Assuming a directory user profile alone explains each failed sign-in and applied policy decision.
  3. Assuming every risky sign-in permanently labels the user as compromised without analysis.
  4. Assuming a guest invitation automatically grants all internal directory privileges.

Explanation

Correct Answer

D:

Assuming a guest invitation automatically grants all internal directory privileges. This belief conflicts with this control principle: Guest collaboration supports external identities under receiving-tenant access controls. The appropriate response instead is: Invite and govern an external guest identity with explicit resource permissions and review.

Incorrect Answers

A:

Assuming an SSPR rollout removes the need to register verification methods or scope eligible users. That caution concerns self-service password reset; the specific misconception here is: Assuming a guest invitation automatically grants all internal directory privileges.

B:

Assuming a directory user profile alone explains each failed sign-in and applied policy decision. That caution concerns sign-in logs; the specific misconception here is: Assuming a guest invitation automatically grants all internal directory privileges.

C:

Assuming every risky sign-in permanently labels the user as compromised without analysis. That caution concerns sign-in risk versus user risk; the specific misconception here is: Assuming a guest invitation automatically grants all internal directory privileges.

Question 133

During an operational risk workshop at a multinational publisher, the incident responder records this concrete requirement: An application needs a security identity to request tokens and access a protected API. The solution must address this requirement directly, without replacing unrelated controls. Which primary response BEST meets the requirement?

  1. Configure an appropriate Entra authentication methods policy and group targeting.
  2. Use a service principal representing the application in the tenant and grant only required permissions.
  3. Target the app and user group with a Conditional Access policy requiring MFA.
  4. Assign suitable Azure role-based access control on the Azure resource scope, not a broad identity role.

Explanation

Correct Answer

B:

Use a service principal representing the application in the tenant and grant only required permissions. A service principal is an application or workload security identity, not an interactive human user. To verify, inspect the application's service principal, credential or trust, and API permission grants.

Incorrect Answers

A:

Configure an appropriate Entra authentication methods policy and group targeting. That addresses a different task: a security team wants to limit which sign-in methods different user groups can register. The present requirement concerns service principal.

C:

Target the app and user group with a Conditional Access policy requiring MFA. That addresses a different task: remote access to a finance app should require MFA for the targeted user group. The present requirement concerns service principal.

D:

Assign suitable Azure role-based access control on the Azure resource scope, not a broad identity role. That addresses a different task: a staff member needs access to an Azure subscription resource but not tenant identity administration. The present requirement concerns service principal.

Question 134

During an operational risk workshop at a multinational publisher, the incident responder records this concrete requirement: An application needs a security identity to request tokens and access a protected API. The solution must address this requirement directly, without replacing unrelated controls. The team implements the following response: Use a service principal representing the application in the tenant and grant only required permissions. Which evidence BEST verifies that the action met its stated purpose?

  1. Find the sign-in event and correlate time, user, application, conditions, and policy result.
  2. Confirm registration and inspect a sign-in where the intended Authenticator method was used.
  3. Inspect the application's service principal, credential or trust, and API permission grants.
  4. Test allowed and disallowed location conditions and inspect actual enforcement logs.

Explanation

Correct Answer

C:

Inspect the application's service principal, credential or trust, and API permission grants. A service principal is an application or workload security identity, not an interactive human user.

Incorrect Answers

A:

Find the sign-in event and correlate time, user, application, conditions, and policy result. This would test sign-in logs, whereas the required evidence is: Inspect the application's service principal, credential or trust, and API permission grants.

B:

Confirm registration and inspect a sign-in where the intended Authenticator method was used. This would test microsoft authenticator, whereas the required evidence is: Inspect the application's service principal, credential or trust, and API permission grants.

D:

Test allowed and disallowed location conditions and inspect actual enforcement logs. This would test conditional access block, whereas the required evidence is: Inspect the application's service principal, credential or trust, and API permission grants.

Question 135

Following a control design challenge at a telecom operator, the security architect has to defend a design against oversimplified assumptions. The requirement is: An application needs a security identity to request tokens and access a protected API. 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. PIM reduces standing privileged access by governing time-bound activation of privileged roles.
  2. Directory roles define delegated administrative capabilities and should follow least privilege.
  3. Self-service password reset permits qualified users to reset their own passwords under defined verification controls.
  4. A service principal is an application or workload security identity, not an interactive human user.

Explanation

Correct Answer

D:

A service principal is an application or workload security identity, not an interactive human user. It explains why the selected measure—Use a service principal representing the application in the tenant and grant only required permissions—fits the specific requirement. It should be verified by checking: Inspect the application's service principal, credential or trust, and API permission grants.

Incorrect Answers

A:

PIM reduces standing privileged access by governing time-bound activation of privileged roles. This describes privileged identity management; the governing concept here is: A service principal is an application or workload security identity, not an interactive human user.

B:

Directory roles define delegated administrative capabilities and should follow least privilege. This describes entra directory roles; the governing concept here is: A service principal is an application or workload security identity, not an interactive human user.

C:

Self-service password reset permits qualified users to reset their own passwords under defined verification controls. This describes self-service password reset; the governing concept here is: A service principal is an application or workload security identity, not an interactive human user.

Question 136

Following a control design challenge at a telecom operator, the security architect has to defend a design against oversimplified assumptions. The requirement is: An application needs a security identity to request tokens and access a protected API. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?

  1. Assuming an application should authenticate by sharing an administrator's human password.
  2. Assuming an SSPR rollout removes the need to register verification methods or scope eligible users.
  3. Assuming legacy username-password protocols offer the same controls as modern token-based sign-in.
  4. Assuming deprovisioning tasks reliably occur without triggering events, scoped workflows, or verification.

Explanation

Correct Answer

A:

Assuming an application should authenticate by sharing an administrator's human password. This belief conflicts with this control principle: A service principal is an application or workload security identity, not an interactive human user. The appropriate response instead is: Use a service principal representing the application in the tenant and grant only required permissions.

Incorrect Answers

B:

Assuming an SSPR rollout removes the need to register verification methods or scope eligible users. That caution concerns self-service password reset; the specific misconception here is: Assuming an application should authenticate by sharing an administrator's human password.

C:

Assuming legacy username-password protocols offer the same controls as modern token-based sign-in. That caution concerns legacy authentication; the specific misconception here is: Assuming an application should authenticate by sharing an administrator's human password.

D:

Assuming deprovisioning tasks reliably occur without triggering events, scoped workflows, or verification. That caution concerns lifecycle workflows; the specific misconception here is: Assuming an application should authenticate by sharing an administrator's human password.

Question 137

During an application integration project at a public university, the identity administrator records this concrete requirement: An Azure workload needs to call a supported Azure service without storing a long-lived secret in code. The solution must address this requirement directly, without replacing unrelated controls. Which primary response BEST meets the requirement?

  1. Review sign-in risk for the specific authentication event and user risk for the overall identity.
  2. Enable and register Microsoft Authenticator using the organization's permitted authentication-method policy.
  3. Use an Azure managed identity and assign the minimum required permissions to the target service.
  4. Require a compliant device in an appropriately scoped Conditional Access grant control.

Explanation

Correct Answer

C:

Use an Azure managed identity and assign the minimum required permissions to the target service. Managed identities provide Azure-managed workload identities, reducing secret handling for supported resources. To verify, verify the resource's managed identity is enabled and successfully obtains a token without embedded credentials.

Incorrect Answers

A:

Review sign-in risk for the specific authentication event and user risk for the overall identity. That addresses a different task: analysts must distinguish suspicious individual authentication events from a potentially compromised identity. The present requirement concerns managed identity.

B:

Enable and register Microsoft Authenticator using the organization's permitted authentication-method policy. That addresses a different task: a workforce needs a supported mobile authenticator for sign-in approval or passwordless experiences. The present requirement concerns managed identity.

D:

Require a compliant device in an appropriately scoped Conditional Access grant control. That addresses a different task: an enterprise app must be accessible only from devices marked compliant under policy. The present requirement concerns managed identity.

Question 138

During an application integration project at a public university, the identity administrator records this concrete requirement: An Azure workload needs to call a supported Azure service without storing a long-lived secret in code. The solution must address this requirement directly, without replacing unrelated controls. The team implements the following response: Use an Azure managed identity and assign the minimum required permissions to the target service. Which evidence BEST verifies that the action met its stated purpose?

  1. Check policy results and device compliance state for allowed and denied test sign-ins.
  2. Inspect role assignments at the subscription or resource and compare them with directory roles.
  3. Review risk detections and affected identities, then confirm the chosen remediation action.
  4. Verify the resource's managed identity is enabled and successfully obtains a token without embedded credentials.

Explanation

Correct Answer

D:

Verify the resource's managed identity is enabled and successfully obtains a token without embedded credentials. Managed identities provide Azure-managed workload identities, reducing secret handling for supported resources.

Incorrect Answers

A:

Check policy results and device compliance state for allowed and denied test sign-ins. This would test conditional access device compliance, whereas the required evidence is: Verify the resource's managed identity is enabled and successfully obtains a token without embedded credentials.

B:

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: Verify the resource's managed identity is enabled and successfully obtains a token without embedded credentials.

C:

Review risk detections and affected identities, then confirm the chosen remediation action. This would test microsoft entra id protection, whereas the required evidence is: Verify the resource's managed identity is enabled and successfully obtains a token without embedded credentials.

Question 139

Following a privileged access audit at a professional services partnership, the compliance analyst has to defend a design against oversimplified assumptions. The requirement is: An Azure workload needs to call a supported Azure service without storing a long-lived secret in code. 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. Managed identities provide Azure-managed workload identities, reducing secret handling for supported resources.
  2. Entitlement management standardizes access requests and lifecycle governance for packaged resources.
  3. Self-service password reset permits qualified users to reset their own passwords under defined verification controls.
  4. Sign-in logs provide evidence of authentication and access policy evaluations.

Explanation

Correct Answer

A:

Managed identities provide Azure-managed workload identities, reducing secret handling for supported resources. It explains why the selected measure—Use an Azure managed identity and assign the minimum required permissions to the target service—fits the specific requirement. It should be verified by checking: Verify the resource's managed identity is enabled and successfully obtains a token without embedded credentials.

Incorrect Answers

B:

Entitlement management standardizes access requests and lifecycle governance for packaged resources. This describes entitlement management; the governing concept here is: Managed identities provide Azure-managed workload identities, reducing secret handling for supported resources.

C:

Self-service password reset permits qualified users to reset their own passwords under defined verification controls. This describes self-service password reset; the governing concept here is: Managed identities provide Azure-managed workload identities, reducing secret handling for supported resources.

D:

Sign-in logs provide evidence of authentication and access policy evaluations. This describes sign-in logs; the governing concept here is: Managed identities provide Azure-managed workload identities, reducing secret handling for supported resources.

Question 140

Following a privileged access audit at a professional services partnership, the compliance analyst has to defend a design against oversimplified assumptions. The requirement is: An Azure workload needs to call a supported Azure service without storing a long-lived secret in code. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?

  1. Assuming access approved once during onboarding never needs re-evaluation.
  2. Assuming managed identity means every reachable Azure service automatically permits the workload access.
  3. Assuming every Entra administrative task requires Global Administrator privileges.
  4. Assuming every eligible user can silently activate any role without activation settings.

Explanation

Correct Answer

B:

Assuming managed identity means every reachable Azure service automatically permits the workload access. This belief conflicts with this control principle: Managed identities provide Azure-managed workload identities, reducing secret handling for supported resources. The appropriate response instead is: Use an Azure managed identity and assign the minimum required permissions to the target service.

Incorrect Answers

A:

Assuming access approved once during onboarding never needs re-evaluation. That caution concerns access reviews; the specific misconception here is: Assuming managed identity means every reachable Azure service automatically permits the workload access.

C:

Assuming every Entra administrative task requires Global Administrator privileges. That caution concerns entra directory roles; the specific misconception here is: Assuming managed identity means every reachable Azure service automatically permits the workload access.

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 managed identity means every reachable Azure service automatically permits the workload access.
