Microsoft SC-900 Practice Test 25

Question 240

At the Willowford software engineering team, a user loses every registered strong authentication method and the helpdesk wants to email a permanent password. Which ongoing control best prevents this issue from recurring?

  1. Review banned terms and password policy monitoring after rebrands
  2. Review risk policy response and detection coverage during security incidents
  3. Review guest access and expiration when partner engagements end
  4. Review pass issuance logging and verification procedures for helpdesk recovery

Explanation

Correct Answer

D:

This control works beyond the initial remediation because it requires the team to review pass issuance logging and verification procedures for helpdesk recovery. This result addresses the stated challenge at the Willowford software engineering team.

Incorrect Answers

A:

That routine supports password protection banned terms, but the relevant ongoing risk requires the team to review pass issuance logging and verification procedures for helpdesk recovery. For the Willowford software engineering team, the direct corrective action is to issue an appropriately scoped Temporary Access Pass through an approved identity recovery workflow.

B:

The suggested review does not track the condition behind the incident. Sustained improvement requires the team to review pass issuance logging and verification procedures for helpdesk recovery. For the Willowford software engineering team, the direct corrective action is to issue an appropriately scoped Temporary Access Pass through an approved identity recovery workflow.

C:

Review guest access and expiration when partner engagements end is not the primary recurring safeguard for this problem. The team should review pass issuance logging and verification procedures for helpdesk recovery. For the Willowford software engineering team, the direct corrective action is to issue an appropriately scoped Temporary Access Pass through an approved identity recovery workflow.

Question 241

At the Pinewick national logistics provider, a high-value application requires phishing-resistant MFA but a broad requirement for any second factor allows weaker verification. Which implementation choice best addresses the situation?

  1. Use supported session revocation and account protection actions for the affected identity
  2. Target the exact security group and validate inclusions and exclusions before enabling the rule
  3. Verify eligible Microsoft Entra licensing before planning Conditional Access deployment
  4. Use an appropriate Conditional Access authentication strength requirement for the sensitive application

Explanation

Correct Answer

D:

The primary failure mode is that not every MFA method delivers the same assurance against credential interception and phishing. The proposed action directly fixes it by requiring the team to use an appropriate Conditional Access authentication strength requirement for the sensitive application; afterward, verify that a pilot SMS-only account is denied while an eligible phishing-resistant sign-in reaches the app. This result addresses the stated challenge at the Pinewick national logistics provider.

Incorrect Answers

A:

This alternative would be suitable where a password reset alone does not necessarily invalidate every already-issued session token instantly. It does not by itself resolve the need to use an appropriate Conditional Access authentication strength requirement for the sensitive application. For the Pinewick national logistics provider, the direct corrective action is to use an appropriate Conditional Access authentication strength requirement for the sensitive application.

B:

Target the exact security group and validate inclusions and exclusions before enabling the rule addresses a different kind of problem: policy evaluation depends on matched identities and selected assignments rather than the administrator's informal description. Here the reported weakness is that not every MFA method delivers the same assurance against credential interception and phishing. For the Pinewick national logistics provider, the direct corrective action is to use an appropriate Conditional Access authentication strength requirement for the sensitive application.

C:

The option addresses the separate situation where some identity access features require additional Entra licensing beyond basic directory service. For this case, the more appropriate response is to use an appropriate Conditional Access authentication strength requirement for the sensitive application. For the Pinewick national logistics provider, the direct corrective action is to use an appropriate Conditional Access authentication strength requirement for the sensitive application.

Question 242

At the Pinewick national logistics provider, a high-value application requires phishing-resistant MFA but a broad requirement for any second factor allows weaker verification. What risk should the team identify as the primary issue?

  1. Not every MFA method delivers the same assurance against credential interception and phishing
  2. Password length alone does not rule out common or organization-specific guessable passwords
  3. An identity provider cannot supply a useful attribute to the app unless it is present and mapped into the expected assertion
  4. Suggested decisions can guide reviewers but the accountable reviewer still needs to evaluate valid access

Explanation

Correct Answer

A:

The situation shows that not every MFA method delivers the same assurance against credential interception and phishing, rather than merely a monitoring or presentation issue. Remediation is to use an appropriate Conditional Access authentication strength requirement for the sensitive application. This result addresses the stated challenge at the Pinewick national logistics provider.

Incorrect Answers

B:

Password length alone does not rule out common or organization-specific guessable passwords. That may occur elsewhere, but the evidence at the Pinewick national logistics provider instead points to the fact that not every MFA method delivers the same assurance against credential interception and phishing.

C:

The proposed cause is relevant to identity attributes and claims, but it does not explain why not every MFA method delivers the same assurance against credential interception and phishing in the reported case. For the Pinewick national logistics provider, the direct corrective action is to use an appropriate Conditional Access authentication strength requirement for the sensitive application.

D:

Suggested decisions can guide reviewers but the accountable reviewer still needs to evaluate valid access. That is not the mechanism that accounts for the stated failure at the Pinewick national logistics provider.

Question 243

At the Pinewick national logistics provider, a high-value application requires phishing-resistant MFA but a broad requirement for any second factor allows weaker verification. What is the strongest acceptance test for this change?

  1. A test password containing a prohibited organization term is rejected at change time
  2. A test application receives a valid token for its configured audience without unapproved permissions
  3. A pilot SMS-only account is denied while an eligible phishing-resistant sign-in reaches the app
  4. An access review addresses membership while a separate DLP test detects the prohibited content transfer

Explanation

Correct Answer

C:

This tests the real business behavior: a pilot SMS-only account is denied while an eligible phishing-resistant sign-in reaches the app. It specifically checks whether the risk that not every MFA method delivers the same assurance against credential interception and phishing has been reduced. This result addresses the stated challenge at the Pinewick national logistics provider.

Incorrect Answers

A:

That observation may be useful for another security or compliance workflow, but the current acceptance test must demonstrate that a pilot SMS-only account is denied while an eligible phishing-resistant sign-in reaches the app. For the Pinewick national logistics provider, the direct corrective action is to use an appropriate Conditional Access authentication strength requirement for the sensitive application.

B:

At the Pinewick national logistics provider, a result about cloud application registration would not show that the team corrected the failure where not every MFA method delivers the same assurance against credential interception and phishing.

D:

This result would validate identity governance versus data dlp, not the intended improvement. The needed observation is that a pilot SMS-only account is denied while an eligible phishing-resistant sign-in reaches the app. For the Pinewick national logistics provider, the direct corrective action is to use an appropriate Conditional Access authentication strength requirement for the sensitive application.

Question 244

At the Pinewick national logistics provider, a high-value application requires phishing-resistant MFA but a broad requirement for any second factor allows weaker verification. Which setting or practice should be reviewed in future?

  1. Review device trust and recovery options after hardware refresh
  2. Audit authentication strength policies after enabling new sign-in methods
  3. Revalidate risk policy licensing when enrollment groups expand
  4. Regularly test and monitor break-glass accounts without using them for routine administration

Explanation

Correct Answer

B:

This control works beyond the initial remediation because it requires the team to audit authentication strength policies after enabling new sign-in methods. This result addresses the stated challenge at the Pinewick national logistics provider.

Incorrect Answers

A:

Review device trust and recovery options after hardware refresh is not the primary recurring safeguard for this problem. The team should audit authentication strength policies after enabling new sign-in methods. For the Pinewick national logistics provider, the direct corrective action is to use an appropriate Conditional Access authentication strength requirement for the sensitive application.

C:

The option would have the team revalidate risk policy licensing when enrollment groups expand. For this situation, the preventive control should instead be to audit authentication strength policies after enabling new sign-in methods. For the Pinewick national logistics provider, the direct corrective action is to use an appropriate Conditional Access authentication strength requirement for the sensitive application.

D:

Although the proposed practice may address cases where broad access controls can create tenant-wide administrative lockout if all recovery identities are subject to the same failing dependency, it does not maintain the specific correction here. For the Pinewick national logistics provider, the direct corrective action is to use an appropriate Conditional Access authentication strength requirement for the sensitive application.

Question 245

At the Birchhaven digital media network, users sign into an application once with a password and conclude it is passwordless merely because later apps do not prompt again. Which corrective action best meets the requirement?

  1. Use supported session revocation and account protection actions for the affected identity
  2. Use Microsoft Entra ID to manage tenant identities and supported cloud application authentication
  3. Distinguish single sign-on session reuse from the authentication method used to establish that session
  4. Use Microsoft Entra entitlement management access packages with suitable approvals and expiration

Explanation

Correct Answer

C:

The reported facts support this change rather than a general platform replacement. The team should distinguish single sign-on session reuse from the authentication method used to establish that session because SSO concerns session propagation across apps whereas passwordless concerns how the initial identity proof is performed. A suitable test confirms that a test records a password-based SSO session and a separate passwordless first sign-in as different flows. This result addresses the stated challenge at the Birchhaven digital media network.

Incorrect Answers

A:

The option addresses the separate situation where a password reset alone does not necessarily invalidate every already-issued session token instantly. For this case, the more appropriate response is to distinguish single sign-on session reuse from the authentication method used to establish that session. For the Birchhaven digital media network, the direct corrective action is to distinguish single sign-on session reuse from the authentication method used to establish that session.

B:

This focuses on entra cloud directory identity management; it does not directly correct the condition that SSO concerns session propagation across apps whereas passwordless concerns how the initial identity proof is performed. For the Birchhaven digital media network, the direct corrective action is to distinguish single sign-on session reuse from the authentication method used to establish that session.

D:

The suggested action is to use Microsoft Entra entitlement management access packages with suitable approvals and expiration, but the facts at the Birchhaven digital media network require a correction for the distinct problem that SSO concerns session propagation across apps whereas passwordless concerns how the initial identity proof is performed.

Question 246

At the Birchhaven digital media network, users sign into an application once with a password and conclude it is passwordless merely because later apps do not prompt again. Which underlying issue most directly explains this situation?

  1. Rate and lockout protections reduce repeated password-guessing opportunities without making every incorrect attempt a permanent ban
  2. SSO concerns session propagation across apps whereas passwordless concerns how the initial identity proof is performed
  3. A legal acceptance requirement is distinct from verifying identity or device compliance
  4. A compromised identity may be abused from different locations so user-level risk is not restricted to one connection

Explanation

Correct Answer

B:

The specific data failure is that SSO concerns session propagation across apps whereas passwordless concerns how the initial identity proof is performed. It can be addressed through the controlled change to distinguish single sign-on session reuse from the authentication method used to establish that session. This result addresses the stated challenge at the Birchhaven digital media network.

Incorrect Answers

A:

The proposed cause is relevant to smart lockout password guessing, but it does not explain why SSO concerns session propagation across apps whereas passwordless concerns how the initial identity proof is performed in the reported case. For the Birchhaven digital media network, the direct corrective action is to distinguish single sign-on session reuse from the authentication method used to establish that session.

C:

The case does not describe the failure mode involving terms of use access condition. Its core issue is that SSO concerns session propagation across apps whereas passwordless concerns how the initial identity proof is performed. For the Birchhaven digital media network, the direct corrective action is to distinguish single sign-on session reuse from the authentication method used to establish that session.

D:

Although a compromised identity may be abused from different locations so user-level risk is not restricted to one connection, the presented symptoms do not support that as the primary cause; they indicate that SSO concerns session propagation across apps whereas passwordless concerns how the initial identity proof is performed. For the Birchhaven digital media network, the direct corrective action is to distinguish single sign-on session reuse from the authentication method used to establish that session.

Question 247

At the Birchhaven digital media network, users sign into an application once with a password and conclude it is passwordless merely because later apps do not prompt again. What evidence would justify considering this concern addressed?

  1. A token for an unrelated API is rejected while a correct-audience token is accepted
  2. A test records a password-based SSO session and a separate passwordless first sign-in as different flows
  3. A requester's attempt to approve their own high-impact elevation is rejected under the defined policy
  4. A decommissioned test app no longer receives tokens or accesses the previously granted resource

Explanation

Correct Answer

B:

The intended correction is to distinguish single sign-on session reuse from the authentication method used to establish that session. The decisive verification is that a test records a password-based SSO session and a separate passwordless first sign-in as different flows, rather than only confirming configuration was saved. This result addresses the stated challenge at the Birchhaven digital media network.

Incorrect Answers

A:

The alternative checks whether a token for an unrelated API is rejected while a correct-audience token is accepted, which is not the direct acceptance criterion for the stated problem. The required result is that a test records a password-based SSO session and a separate passwordless first sign-in as different flows. For the Birchhaven digital media network, the direct corrective action is to distinguish single sign-on session reuse from the authentication method used to establish that session.

C:

This verifies a separate issue in security administration. It does not prove that a test records a password-based SSO session and a separate passwordless first sign-in as different flows for the reported situation. For the Birchhaven digital media network, the direct corrective action is to distinguish single sign-on session reuse from the authentication method used to establish that session.

D:

The cited result is too remote from the corrective action to distinguish single sign-on session reuse from the authentication method used to establish that session. The direct evidence should show that a test records a password-based SSO session and a separate passwordless first sign-in as different flows. For the Birchhaven digital media network, the direct corrective action is to distinguish single sign-on session reuse from the authentication method used to establish that session.

Question 248

At the Birchhaven digital media network, users sign into an application once with a password and conclude it is passwordless merely because later apps do not prompt again. How should the organization sustain the improvement?

  1. Monitor registration coverage and recovery requests during deployment
  2. Review targeted applications and exclusions during payroll app changes
  3. Review sign-in method metrics separately from SSO success measures
  4. Monitor sync health and conflict errors after directory changes

Explanation

Correct Answer

C:

The continuing safeguard is to review sign-in method metrics separately from SSO success measures. It helps avoid the original condition: SSO concerns session propagation across apps whereas passwordless concerns how the initial identity proof is performed. This result addresses the stated challenge at the Birchhaven digital media network.

Incorrect Answers

A:

The option would have the team monitor registration coverage and recovery requests during deployment. For this situation, the preventive control should instead be to review sign-in method metrics separately from SSO success measures. For the Birchhaven digital media network, the direct corrective action is to distinguish single sign-on session reuse from the authentication method used to establish that session.

B:

Although the proposed practice may address cases where Conditional Access evaluates policy conditions and grants beyond the initial password verification, it does not maintain the specific correction here. For the Birchhaven digital media network, the direct corrective action is to distinguish single sign-on session reuse from the authentication method used to establish that session.

D:

The suggested review does not track the condition behind the incident. Sustained improvement requires the team to review sign-in method metrics separately from SSO success measures. For the Birchhaven digital media network, the direct corrective action is to distinguish single sign-on session reuse from the authentication method used to establish that session.

Question 249

At the Oakport national logistics provider, operators suspect an MFA failure but examine only user account attributes and never look at sign-in events. Which approach best resolves the identified risk?

  1. Deploy a supported FIDO2 security key or appropriate passkey method for eligible users
  2. Inspect Microsoft Entra sign-in logs for method and policy outcome details
  3. Configure supported claims or user attribute mapping for the authorized relying application
  4. Create a governed application or workload identity with only the necessary application permissions

Explanation

Correct Answer

B:

For the Oakport national logistics provider, the appropriate correction is to inspect Microsoft Entra sign-in logs for method and policy outcome details. The decisive reason is that identity profile data alone does not explain which authentication step or access rule denied a particular sign-in; acceptance evidence is that a recorded pilot sign-in failure identifies the relevant authentication or Conditional Access result.

Incorrect Answers

A:

Deploy a supported FIDO2 security key or appropriate passkey method for eligible users can be useful for another workload, but it leaves the immediate failure unresolved. Here the priority is to inspect Microsoft Entra sign-in logs for method and policy outcome details. For the Oakport national logistics provider, the direct corrective action is to inspect Microsoft Entra sign-in logs for method and policy outcome details.

C:

This alternative would be suitable where an identity provider cannot supply a useful attribute to the app unless it is present and mapped into the expected assertion. It does not by itself resolve the need to inspect Microsoft Entra sign-in logs for method and policy outcome details. For the Oakport national logistics provider, the direct corrective action is to inspect Microsoft Entra sign-in logs for method and policy outcome details.

D:

Create a governed application or workload identity with only the necessary application permissions addresses a different kind of problem: noninteractive processes should authenticate as workload identities instead of depending on human sign-in sessions. Here the reported weakness is that identity profile data alone does not explain which authentication step or access rule denied a particular sign-in. For the Oakport national logistics provider, the direct corrective action is to inspect Microsoft Entra sign-in logs for method and policy outcome details.

Question 250

At the Oakport national logistics provider, operators suspect an MFA failure but examine only user account attributes and never look at sign-in events. Which explanation best accounts for the concern?

  1. A valid cryptographic signature does not make a token intended for one audience valid for another application
  2. Identity profile data alone does not explain which authentication step or access rule denied a particular sign-in
  3. Broad access controls can create tenant-wide administrative lockout if all recovery identities are subject to the same failing dependency
  4. Independent review reduces the chance that one identity can self-authorize sensitive access

Explanation

Correct Answer

B:

The problem stems from the fact that identity profile data alone does not explain which authentication step or access rule denied a particular sign-in. A correct solution would inspect Microsoft Entra sign-in logs for method and policy outcome details and check that a recorded pilot sign-in failure identifies the relevant authentication or Conditional Access result. This result addresses the stated challenge at the Oakport national logistics provider.

Incorrect Answers

A:

The case does not describe the failure mode involving token audience verification. Its core issue is that identity profile data alone does not explain which authentication step or access rule denied a particular sign-in. For the Oakport national logistics provider, the direct corrective action is to inspect Microsoft Entra sign-in logs for method and policy outcome details.

C:

This explanation belongs to a different security or compliance situation. In this case, the observable gap is that identity profile data alone does not explain which authentication step or access rule denied a particular sign-in. For the Oakport national logistics provider, the direct corrective action is to inspect Microsoft Entra sign-in logs for method and policy outcome details.

D:

Independent review reduces the chance that one identity can self-authorize sensitive access. That may occur elsewhere, but the evidence at the Oakport national logistics provider instead points to the fact that identity profile data alone does not explain which authentication step or access rule denied a particular sign-in.
