Microsoft SC-900 Practice Test 30

Question 290

During an infrastructure modernization effort at a managed services company, the technology auditor records this concrete requirement: An organization wants stronger proof at sign-in than a password alone. The solution must address this requirement directly, without replacing unrelated controls. The team implements the following response: Require a suitable additional authentication factor through Entra authentication controls. 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. Examine sign-in details to confirm an additional factor requirement was satisfied for the protected attempt.
  3. Review the access-package request, approval decision, assignment, and expiration event.
  4. Review eligibility, activation request, duration, approval requirements, and audit record.

Explanation

Correct Answer

B:

Examine sign-in details to confirm an additional factor requirement was satisfied for the protected attempt. This tests the relevant control rather than an adjacent capability. The implemented response is: Require a suitable additional authentication factor through Entra authentication controls. The control principle is: MFA combines separate authentication factors to reduce the risk of password-only account compromise.

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: Examine sign-in details to confirm an additional factor requirement was satisfied for the protected attempt.

C:

Review the access-package request, approval decision, assignment, and expiration event. This would test entitlement management, whereas the required evidence is: Examine sign-in details to confirm an additional factor requirement was satisfied for the protected attempt.

D:

Review eligibility, activation request, duration, approval requirements, and audit record. This would test privileged identity management, whereas the required evidence is: Examine sign-in details to confirm an additional factor requirement was satisfied for the protected attempt.

Question 291

Following a tabletop exercise at a retail payments business, the enterprise architect has to defend a design against oversimplified assumptions. The requirement is: An organization wants stronger proof at sign-in than a password alone. 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. A service principal is an application or workload security identity, not an interactive human user.
  3. MFA combines separate authentication factors to reduce the risk of password-only account compromise.
  4. Report-only mode models potential policy outcomes without enforcing a grant or block requirement.

Explanation

Correct Answer

C:

MFA combines separate authentication factors to reduce the risk of password-only account compromise. It explains why the selected measure—Require a suitable additional authentication factor through Entra authentication controls—fits the specific requirement. It should be verified by checking: Examine sign-in details to confirm an additional factor requirement was satisfied for the protected attempt.

Incorrect Answers

A:

Directory roles define delegated administrative capabilities and should follow least privilege. This describes entra directory roles; the governing concept here is: MFA combines separate authentication factors to reduce the risk of password-only account compromise.

B:

A service principal is an application or workload security identity, not an interactive human user. This describes service principal; the governing concept here is: MFA combines separate authentication factors to reduce the risk of password-only account compromise.

D:

Report-only mode models potential policy outcomes without enforcing a grant or block requirement. This describes conditional access report-only; the governing concept here is: MFA combines separate authentication factors to reduce the risk of password-only account compromise.

Question 292

Following a tabletop exercise at a retail payments business, the enterprise architect has to defend a design against oversimplified assumptions. The requirement is: An organization wants stronger proof at sign-in than a password alone. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?

  1. Assuming deprovisioning tasks reliably occur without triggering events, scoped workflows, or verification.
  2. Assuming Entra ID itself inspects all virtual-network packets like a network security appliance.
  3. Assuming every Entra administrative task requires Global Administrator privileges.
  4. Assuming two separate passwords always constitute two independent authentication factors.

Explanation

Correct Answer

D:

Assuming two separate passwords always constitute two independent authentication factors. This belief conflicts with this control principle: MFA combines separate authentication factors to reduce the risk of password-only account compromise. The appropriate response instead is: Require a suitable additional authentication factor through Entra authentication controls.

Incorrect Answers

A:

Assuming deprovisioning tasks reliably occur without triggering events, scoped workflows, or verification. That caution concerns lifecycle workflows; the specific misconception here is: Assuming two separate passwords always constitute two independent authentication factors.

B:

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 two separate passwords always constitute two independent authentication factors.

C:

Assuming every Entra administrative task requires Global Administrator privileges. That caution concerns entra directory roles; the specific misconception here is: Assuming two separate passwords always constitute two independent authentication factors.

Question 293

During a regulated-workload onboarding at a national retailer, the information governance lead records this concrete requirement: A workforce needs a supported mobile authenticator for sign-in approval or passwordless experiences. The solution must address this requirement directly, without replacing unrelated controls. Which primary response BEST meets the requirement?

  1. Use Conditional Access report-only mode and review sign-in evaluations before enabling enforcement.
  2. Enable and register Microsoft Authenticator using the organization's permitted authentication-method policy.
  3. Configure a scoped Conditional Access block-access policy for matching sign-ins.
  4. Assign suitable access to a managed Entra group rather than maintaining each user assignment individually.

Explanation

Correct Answer

B:

Enable and register Microsoft Authenticator using the organization's permitted authentication-method policy. This is the best match because Authenticator is an authentication method; it is not an authorization role assignment. A practical confirmation is: Confirm registration and inspect a sign-in where the intended Authenticator method was used.

Incorrect Answers

A:

Use Conditional Access report-only mode and review sign-in evaluations before enabling enforcement. That addresses a different task: a team needs to assess policy effects before enforcing a new requirement across a large population. The present requirement concerns microsoft authenticator.

C:

Configure a scoped Conditional Access block-access policy for matching sign-ins. That addresses a different task: administrators must deny access attempts matching a prohibited location rule. The present requirement concerns microsoft authenticator.

D:

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 microsoft authenticator.

Question 294

During a regulated-workload onboarding at a national retailer, the information governance lead records this concrete requirement: A workforce needs a supported mobile authenticator for sign-in approval or passwordless experiences. The solution must address this requirement directly, without replacing unrelated controls. The team implements the following response: Enable and register Microsoft Authenticator using the organization's permitted authentication-method policy. Which evidence BEST verifies that the action met its stated purpose?

  1. Compare the event-level risk record with the user-level risk status and remediation history.
  2. Test allowed and disallowed location conditions and inspect actual enforcement logs.
  3. Confirm registration and inspect a sign-in where the intended Authenticator method was used.
  4. Review targeted sign-ins to verify the user completed the MFA requirement.

Explanation

Correct Answer

C:

Confirm registration and inspect a sign-in where the intended Authenticator method was used. This tests the relevant control rather than an adjacent capability. The implemented response is: Enable and register Microsoft Authenticator using the organization's permitted authentication-method policy. The control principle is: Authenticator is an authentication method; it is not an authorization role assignment.

Incorrect Answers

A:

Compare the event-level risk record with the user-level risk status and remediation history. That result would support an assessment of sign-in risk versus user risk, not the microsoft authenticator measure implemented in this case. The appropriate observation is: Confirm registration and inspect a sign-in where the intended Authenticator method was used.

B:

Test allowed and disallowed location conditions and inspect actual enforcement logs. That result would support an assessment of conditional access block, not the microsoft authenticator measure implemented in this case. The appropriate observation is: Confirm registration and inspect a sign-in where the intended Authenticator method was used.

D:

Review targeted sign-ins to verify the user completed the MFA requirement. This would test conditional access mfa requirement, whereas the required evidence is: Confirm registration and inspect a sign-in where the intended Authenticator method was used.

Question 295

Following a compliance walkthrough at an international shipping company, the training coordinator has to defend a design against oversimplified assumptions. The requirement is: A workforce needs a supported mobile authenticator for sign-in approval or passwordless experiences. 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. Member identities typically represent internal tenant users with organizational lifecycle governance.
  2. Access reviews support ongoing access recertification and least privilege.
  3. Conditional Access grant controls can require additional authentication before protected app access.
  4. Authenticator is an authentication method; it is not an authorization role assignment.

Explanation

Correct Answer

D:

Authenticator is an authentication method; it is not an authorization role assignment. It explains why the selected measure—Enable and register Microsoft Authenticator using the organization's permitted authentication-method policy—fits the specific requirement. It should be verified by checking: Confirm registration and inspect a sign-in where the intended Authenticator method was used.

Incorrect Answers

A:

Member identities typically represent internal tenant users with organizational lifecycle governance. This statement belongs to member user identity; it does not directly explain the narrower requirement here. The governing concept for this case is: Authenticator is an authentication method; it is not an authorization role assignment.

B:

Access reviews support ongoing access recertification and least privilege. This statement belongs to access reviews; it does not directly explain the narrower requirement here. The governing concept for this case is: Authenticator is an authentication method; it is not an authorization role assignment.

C:

Conditional Access grant controls can require additional authentication before protected app access. This describes conditional access mfa requirement; the governing concept here is: Authenticator is an authentication method; it is not an authorization role assignment.

Question 296

Following a compliance walkthrough at an international shipping company, the training coordinator has to defend a design against oversimplified assumptions. The requirement is: A workforce needs a supported mobile authenticator for sign-in approval or passwordless experiences. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?

  1. Assuming installing the app automatically grants the user more data access rights.
  2. Assuming a report-only block policy will prevent production access.
  3. Assuming every risky sign-in permanently labels the user as compromised without analysis.
  4. Treating report-only policy matches as proof that users were actually blocked.

Explanation

Correct Answer

A:

Assuming installing the app automatically grants the user more data access rights. This belief conflicts with this control principle: Authenticator is an authentication method; it is not an authorization role assignment. The appropriate response instead is: Enable and register Microsoft Authenticator using the organization's permitted authentication-method policy.

Incorrect Answers

B:

Assuming a report-only block policy will prevent production access. That caution concerns conditional access block; the specific misconception here is: Assuming installing the app automatically grants the user more data access rights.

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 installing the app automatically grants the user more data access rights.

D:

Treating report-only policy matches as proof that users were actually blocked. That caution concerns conditional access report-only; the specific misconception here is: Assuming installing the app automatically grants the user more data access rights.

Question 297

During an operational risk workshop at a financial software company, the security architect records this concrete requirement: High-risk users need phishing-resistant authentication with a physical security key. The solution must address this requirement directly, without replacing unrelated controls. Which primary response BEST meets the requirement?

  1. Use Microsoft Entra entitlement management access packages with policies, approval, and expiration rules.
  2. Use a service principal representing the application in the tenant and grant only required permissions.
  3. Enable supported FIDO2 security-key authentication and register keys for the targeted users.
  4. Define a Conditional Access policy with relevant assignments, conditions, and grant or block controls.

Explanation

Correct Answer

C:

Enable supported FIDO2 security-key authentication and register keys for the targeted users. This is the best match because FIDO2 uses public-key credentials bound to the legitimate authenticator and relying party. A practical confirmation is: Confirm an accepted FIDO2 method in authentication-method registration and a phishing-resistant sign-in.

Incorrect Answers

A:

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 fido2 security key.

B:

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 fido2 security key.

D:

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 fido2 security key.

Question 298

During an operational risk workshop at a financial software company, the security architect records this concrete requirement: High-risk users need phishing-resistant authentication with a physical security key. The solution must address this requirement directly, without replacing unrelated controls. The team implements the following response: Enable supported FIDO2 security-key authentication and register keys for the targeted users. Which evidence BEST verifies that the action met its stated purpose?

  1. Inspect review decisions and verify excess memberships or assignments were removed as intended.
  2. Use sign-in policy evaluation and What If analysis to confirm the right users and applications match.
  3. Check user and application objects and successful identity-provider sign-ins in the Entra tenant.
  4. Confirm an accepted FIDO2 method in authentication-method registration and a phishing-resistant sign-in.

Explanation

Correct Answer

D:

Confirm an accepted FIDO2 method in authentication-method registration and a phishing-resistant sign-in. This tests the relevant control rather than an adjacent capability. The implemented response is: Enable supported FIDO2 security-key authentication and register keys for the targeted users. The control principle is: FIDO2 uses public-key credentials bound to the legitimate authenticator and relying party.

Incorrect Answers

A:

Inspect review decisions and verify excess memberships or assignments were removed as intended. This would test access reviews, whereas the required evidence is: Confirm an accepted FIDO2 method in authentication-method registration and a phishing-resistant sign-in.

B:

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 an accepted FIDO2 method in authentication-method registration and a phishing-resistant sign-in.

C:

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: Confirm an accepted FIDO2 method in authentication-method registration and a phishing-resistant sign-in.

Question 299

Following a privacy readiness assessment at a digital payments startup, the cloud platform manager has to defend a design against oversimplified assumptions. The requirement is: High-risk users need phishing-resistant authentication with a physical security key. 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. FIDO2 uses public-key credentials bound to the legitimate authenticator and relying party.
  2. Managed identities provide Azure-managed workload identities, reducing secret handling for supported resources.
  3. Directory roles define delegated administrative capabilities and should follow least privilege.
  4. Identity Protection applies risk signals to identify potentially compromised sign-ins or user identities.

Explanation

Correct Answer

A:

FIDO2 uses public-key credentials bound to the legitimate authenticator and relying party. It explains why the selected measure—Enable supported FIDO2 security-key authentication and register keys for the targeted users—fits the specific requirement. It should be verified by checking: Confirm an accepted FIDO2 method in authentication-method registration and a phishing-resistant sign-in.

Incorrect Answers

B:

Managed identities provide Azure-managed workload identities, reducing secret handling for supported resources. This describes managed identity; the governing concept here is: FIDO2 uses public-key credentials bound to the legitimate authenticator and relying party.

C:

Directory roles define delegated administrative capabilities and should follow least privilege. This describes entra directory roles; the governing concept here is: FIDO2 uses public-key credentials bound to the legitimate authenticator and relying party.

D:

Identity Protection applies risk signals to identify potentially compromised sign-ins or user identities. This describes microsoft entra id protection; the governing concept here is: FIDO2 uses public-key credentials bound to the legitimate authenticator and relying party.

Question 300

Following a privacy readiness assessment at a digital payments startup, the cloud platform manager has to defend a design against oversimplified assumptions. The requirement is: High-risk users need phishing-resistant authentication with a physical security key. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?

  1. Assuming deprovisioning tasks reliably occur without triggering events, scoped workflows, or verification.
  2. Assuming a reusable code sent to any website provides the same phishing resistance as FIDO2.
  3. Assuming managed identity means every reachable Azure service automatically permits the workload access.
  4. Assuming group membership bypasses all resource-level access checks.

Explanation

Correct Answer

B:

Assuming a reusable code sent to any website provides the same phishing resistance as FIDO2. This belief conflicts with this control principle: FIDO2 uses public-key credentials bound to the legitimate authenticator and relying party. The appropriate response instead is: Enable supported FIDO2 security-key authentication and register keys for the targeted users.

Incorrect Answers

A:

Assuming deprovisioning tasks reliably occur without triggering events, scoped workflows, or verification. That caution concerns lifecycle workflows; the specific misconception here is: Assuming a reusable code sent to any website provides the same phishing resistance as FIDO2.

C:

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 reusable code sent to any website provides the same phishing resistance as FIDO2.

D:

Assuming group membership bypasses all resource-level access checks. That caution concerns groups for access; the specific misconception here is: Assuming a reusable code sent to any website provides the same phishing resistance as FIDO2.
