Microsoft SC-900 Practice Test 14

Question 130

At the Uptonbridge financial services firm, a supplier needs access to one collaboration resource but staff plan to create a full internal employee identity for the supplier. Which explanation best accounts for the concern?

  1. User identity creation and client application registration are separate elements of an OAuth sign-in integration
  2. Two knowledge-only secrets do not necessarily represent different authentication factor types
  3. Role design should match actual permitted actions rather than copying the broadest available administrator
  4. External collaboration can use guest identities rather than treating every partner as an internal workforce member

Explanation

Correct Answer

D:

This identifies the root issue: external collaboration can use guest identities rather than treating every partner as an internal workforce member. At the Uptonbridge financial services firm, the team should therefore use appropriate Microsoft Entra B2B guest collaboration and narrowly scoped resource access.

Incorrect Answers

A:

The case does not describe the failure mode involving cloud application registration. Its core issue is that external collaboration can use guest identities rather than treating every partner as an internal workforce member. For the Uptonbridge financial services firm, the direct corrective action is to use appropriate Microsoft Entra B2B guest collaboration and narrowly scoped resource access.

B:

Although two knowledge-only secrets do not necessarily represent different authentication factor types, the presented symptoms do not support that as the primary cause; they indicate that external collaboration can use guest identities rather than treating every partner as an internal workforce member. For the Uptonbridge financial services firm, the direct corrective action is to use appropriate Microsoft Entra B2B guest collaboration and narrowly scoped resource access.

C:

This explanation belongs to a different security or compliance situation. In this case, the observable gap is that external collaboration can use guest identities rather than treating every partner as an internal workforce member. For the Uptonbridge financial services firm, the direct corrective action is to use appropriate Microsoft Entra B2B guest collaboration and narrowly scoped resource access.

Question 131

At the Uptonbridge financial services firm, a supplier needs access to one collaboration resource but staff plan to create a full internal employee identity for the supplier. Which test result best shows the requirement is met?

  1. A guest signs in with permitted external identity credentials and reaches only the authorized resource
  2. A user account signs into an authorized Microsoft 365 application using the Entra tenant identity
  3. A pilot role remains inactive until the approved activation and automatically expires afterward
  4. A recorded pilot sign-in failure identifies the relevant authentication or Conditional Access result

Explanation

Correct Answer

A:

At the Uptonbridge financial services firm, evidence that a guest signs in with permitted external identity credentials and reaches only the authorized resource directly validates the correction, instead of testing a neighboring service.

Incorrect Answers

B:

The cited result is too remote from the corrective action to use appropriate Microsoft Entra B2B guest collaboration and narrowly scoped resource access. The direct evidence should show that a guest signs in with permitted external identity credentials and reaches only the authorized resource. For the Uptonbridge financial services firm, the direct corrective action is to use appropriate Microsoft Entra B2B guest collaboration and narrowly scoped resource access.

C:

That observation may be useful for another security or compliance workflow, but the current acceptance test must demonstrate that a guest signs in with permitted external identity credentials and reaches only the authorized resource. For the Uptonbridge financial services firm, the direct corrective action is to use appropriate Microsoft Entra B2B guest collaboration and narrowly scoped resource access.

D:

At the Uptonbridge financial services firm, a result about authentication sign-in logs would not show that the team corrected the failure where external collaboration can use guest identities rather than treating every partner as an internal workforce member.

Question 132

At the Uptonbridge financial services firm, a supplier needs access to one collaboration resource but staff plan to create a full internal employee identity for the supplier. Which ongoing control best prevents this issue from recurring?

  1. Review managed identity permissions and resource ownership after redeployment
  2. Review guest access and expiration when partner engagements end
  3. Monitor lifecycle workflow errors and ownership after HR process changes
  4. Retest token validation after authentication library upgrades

Explanation

Correct Answer

B:

The needed prevention is to review guest access and expiration when partner engagements end. It directly sustains the original change to use appropriate Microsoft Entra B2B guest collaboration and narrowly scoped resource access. This result addresses the stated challenge at the Uptonbridge financial services firm.

Incorrect Answers

A:

That routine supports managed identity for azure workload, but the relevant ongoing risk requires the team to review guest access and expiration when partner engagements end. For the Uptonbridge financial services firm, the direct corrective action is to use appropriate Microsoft Entra B2B guest collaboration and narrowly scoped resource access.

C:

Monitor lifecycle workflow errors and ownership after HR process changes is not the primary recurring safeguard for this problem. The team should review guest access and expiration when partner engagements end. For the Uptonbridge financial services firm, the direct corrective action is to use appropriate Microsoft Entra B2B guest collaboration and narrowly scoped resource access.

D:

This is a maintenance action for a different security or compliance situation, rather than the one that originally failed because external collaboration can use guest identities rather than treating every partner as an internal workforce member. For the Uptonbridge financial services firm, the direct corrective action is to use appropriate Microsoft Entra B2B guest collaboration and narrowly scoped resource access.

Question 133

At the Juniperford regional airport, a partner receives a guest invitation but cannot access a shared app because the invitation and account context were not completed. Which implementation choice best addresses the situation?

  1. Assign the application service principal the minimum suitable authorization at the resource scope
  2. Validate token issuer audience expiry and required claims at the relying application
  3. Complete the supported B2B guest invitation and redemption flow before granting app access
  4. Deploy a supported FIDO2 security key or appropriate passkey method for eligible users

Explanation

Correct Answer

C:

This is the direct security or compliance remedy: complete the supported B2B guest invitation and redemption flow before granting app access. The observed risk is that an invited external identity may require acceptance and proper guest object mapping before use; a passing acceptance check would show that the invited partner redeems the invitation and reaches the approved app without unrestricted tenant access. This result addresses the stated challenge at the Juniperford regional airport.

Incorrect Answers

A:

This alternative would be suitable where registering an application establishes an identity but does not itself grant permission to every target resource. It does not by itself resolve the need to complete the supported B2B guest invitation and redemption flow before granting app access. For the Juniperford regional airport, the direct corrective action is to complete the supported B2B guest invitation and redemption flow before granting app access.

B:

Validate token issuer audience expiry and required claims at the relying application addresses a different kind of problem: a valid cryptographic signature does not make a token intended for one audience valid for another application. Here the reported weakness is that an invited external identity may require acceptance and proper guest object mapping before use. For the Juniperford regional airport, the direct corrective action is to complete the supported B2B guest invitation and redemption flow before granting app access.

D:

This focuses on passwordless fido2 security key; it does not directly correct the condition that an invited external identity may require acceptance and proper guest object mapping before use. For the Juniperford regional airport, the direct corrective action is to complete the supported B2B guest invitation and redemption flow before granting app access.

Question 134

At the Juniperford regional airport, a partner receives a guest invitation but cannot access a shared app because the invitation and account context were not completed. What risk should the team identify as the primary issue?

  1. User identity creation and client application registration are separate elements of an OAuth sign-in integration
  2. A password reset alone does not necessarily invalidate every already-issued session token instantly
  3. An invited external identity may require acceptance and proper guest object mapping before use
  4. A cloud-only password change does not always update the on-premises credential without the designed hybrid integration

Explanation

Correct Answer

C:

The evidence indicates that an invited external identity may require acceptance and proper guest object mapping before use. The appropriate response is to complete the supported B2B guest invitation and redemption flow before granting app access and demonstrate that the invited partner redeems the invitation and reaches the approved app without unrestricted tenant access. This result addresses the stated challenge at the Juniperford regional airport.

Incorrect Answers

A:

This explanation belongs to a different security or compliance situation. In this case, the observable gap is that an invited external identity may require acceptance and proper guest object mapping before use. For the Juniperford regional airport, the direct corrective action is to complete the supported B2B guest invitation and redemption flow before granting app access.

B:

A password reset alone does not necessarily invalidate every already-issued session token instantly. That may occur elsewhere, but the evidence at the Juniperford regional airport instead points to the fact that an invited external identity may require acceptance and proper guest object mapping before use.

D:

A cloud-only password change does not always update the on-premises credential without the designed hybrid integration. That is not the mechanism that accounts for the stated failure at the Juniperford regional airport.

Question 135

At the Juniperford regional airport, a partner receives a guest invitation but cannot access a shared app because the invitation and account context were not completed. What is the strongest acceptance test for this change?

  1. A pilot user retains the intended attributes and cloud identity after synchronization
  2. The invited partner redeems the invitation and reaches the approved app without unrestricted tenant access
  3. An external pilot user must accept the correct agreement before the app grants access
  4. An assigned employee enters the app while an unassigned user from the same tenant is denied

Explanation

Correct Answer

B:

The team can confirm the fix by showing that the invited partner redeems the invitation and reaches the approved app without unrestricted tenant access. This aligns with the corrective design to complete the supported B2B guest invitation and redemption flow before granting app access. This result addresses the stated challenge at the Juniperford regional airport.

Incorrect Answers

A:

That observation may be useful for another security or compliance workflow, but the current acceptance test must demonstrate that the invited partner redeems the invitation and reaches the approved app without unrestricted tenant access. For the Juniperford regional airport, the direct corrective action is to complete the supported B2B guest invitation and redemption flow before granting app access.

C:

The alternative checks whether an external pilot user must accept the correct agreement before the app grants access, which is not the direct acceptance criterion for the stated problem. The required result is that the invited partner redeems the invitation and reaches the approved app without unrestricted tenant access. For the Juniperford regional airport, the direct corrective action is to complete the supported B2B guest invitation and redemption flow before granting app access.

D:

This result would validate app role assignment authorization, not the intended improvement. The needed observation is that the invited partner redeems the invitation and reaches the approved app without unrestricted tenant access. For the Juniperford regional airport, the direct corrective action is to complete the supported B2B guest invitation and redemption flow before granting app access.

Question 136

At the Juniperford regional airport, a partner receives a guest invitation but cannot access a shared app because the invitation and account context were not completed. Which setting or practice should be reviewed in future?

  1. Monitor pending invitations and inactive guests during partner onboarding
  2. Review managed identity permissions and resource ownership after redeployment
  3. Regularly test and monitor break-glass accounts without using them for routine administration
  4. Review named location IP ranges when network providers change

Explanation

Correct Answer

A:

After implementation, the team should monitor pending invitations and inactive guests during partner onboarding as the appropriate recurring safeguard against the identified issue. This result addresses the stated challenge at the Juniperford regional airport.

Incorrect Answers

B:

This is a maintenance action for a different security or compliance situation, rather than the one that originally failed because an invited external identity may require acceptance and proper guest object mapping before use. For the Juniperford regional airport, the direct corrective action is to complete the supported B2B guest invitation and redemption flow before granting app access.

C:

The option would have the team regularly test and monitor break-glass accounts without using them for routine administration. For this situation, the preventive control should instead be to monitor pending invitations and inactive guests during partner onboarding. For the Juniperford regional airport, the direct corrective action is to complete the supported B2B guest invitation and redemption flow before granting app access.

D:

Although the proposed practice may address cases where identity credentials by themselves do not evaluate the network-location risk requirement, it does not maintain the specific correction here. For the Juniperford regional airport, the direct corrective action is to complete the supported B2B guest invitation and redemption flow before granting app access.

Question 137

At the Brookfield financial services firm, a scheduled integration relies on a named employee account to call Microsoft Graph without user interaction. Which corrective action best meets the requirement?

  1. Use Microsoft Entra ID to manage tenant identities and supported cloud application authentication
  2. Verify eligible Microsoft Entra licensing before planning Conditional Access deployment
  3. Create a governed application or workload identity with only the necessary application permissions
  4. Target the exact security group and validate inclusions and exclusions before enabling the rule

Explanation

Correct Answer

C:

The reported facts support this change rather than a general platform replacement. The team should create a governed application or workload identity with only the necessary application permissions because noninteractive processes should authenticate as workload identities instead of depending on human sign-in sessions. A suitable test confirms that the integration runs after the employee's account is disabled and unrelated API calls remain denied. This result addresses the stated challenge at the Brookfield financial services firm.

Incorrect Answers

A:

The option addresses the separate situation where Entra ID supplies cloud identity and access capabilities across Microsoft and integrated applications. For this case, the more appropriate response is to create a governed application or workload identity with only the necessary application permissions. For the Brookfield financial services firm, the direct corrective action is to create a governed application or workload identity with only the necessary application permissions.

B:

This focuses on conditional access licensing recognition; it does not directly correct the condition that noninteractive processes should authenticate as workload identities instead of depending on human sign-in sessions. For the Brookfield financial services firm, the direct corrective action is to create a governed application or workload identity with only the necessary application permissions.

D:

The suggested action is to target the exact security group and validate inclusions and exclusions before enabling the rule, but the facts at the Brookfield financial services firm require a correction for the distinct problem that noninteractive processes should authenticate as workload identities instead of depending on human sign-in sessions.

Question 138

At the Brookfield financial services firm, a scheduled integration relies on a named employee account to call Microsoft Graph without user interaction. Which underlying issue most directly explains this situation?

  1. A system-assigned managed identity is bound to a particular resource lifetime whereas a user-assigned one has its own lifecycle
  2. Noninteractive processes should authenticate as workload identities instead of depending on human sign-in sessions
  3. Independent review reduces the chance that one identity can self-authorize sensitive access
  4. Manually disconnected HR and identity processes can leave active credentials after organizational departure

Explanation

Correct Answer

B:

The specific data failure is that noninteractive processes should authenticate as workload identities instead of depending on human sign-in sessions. It can be addressed through the controlled change to create a governed application or workload identity with only the necessary application permissions. This result addresses the stated challenge at the Brookfield financial services firm.

Incorrect Answers

A:

The proposed cause is relevant to system-assigned versus user-assigned identity, but it does not explain why noninteractive processes should authenticate as workload identities instead of depending on human sign-in sessions in the reported case. For the Brookfield financial services firm, the direct corrective action is to create a governed application or workload identity with only the necessary application permissions.

C:

The case does not describe the failure mode involving separation of duties approvals. Its core issue is that noninteractive processes should authenticate as workload identities instead of depending on human sign-in sessions. For the Brookfield financial services firm, the direct corrective action is to create a governed application or workload identity with only the necessary application permissions.

D:

Although manually disconnected HR and identity processes can leave active credentials after organizational departure, the presented symptoms do not support that as the primary cause; they indicate that noninteractive processes should authenticate as workload identities instead of depending on human sign-in sessions. For the Brookfield financial services firm, the direct corrective action is to create a governed application or workload identity with only the necessary application permissions.

Question 139

At the Brookfield financial services firm, a scheduled integration relies on a named employee account to call Microsoft Graph without user interaction. What evidence would justify considering this concern addressed?

  1. A representative hybrid user signs in through the selected method and authentication logs show the expected flow
  2. The integration runs after the employee's account is disabled and unrelated API calls remain denied
  3. A licensing check confirms the required policy capability is available for the targeted users
  4. The operator reads the designated storage diagnostics while a write attempt on unrelated resources is denied

Explanation

Correct Answer

B:

The intended correction is to create a governed application or workload identity with only the necessary application permissions. The decisive verification is that the integration runs after the employee's account is disabled and unrelated API calls remain denied, rather than only confirming configuration was saved. This result addresses the stated challenge at the Brookfield financial services firm.

Incorrect Answers

A:

The alternative checks whether a representative hybrid user signs in through the selected method and authentication logs show the expected flow, which is not the direct acceptance criterion for the stated problem. The required result is that the integration runs after the employee's account is disabled and unrelated API calls remain denied. For the Brookfield financial services firm, the direct corrective action is to create a governed application or workload identity with only the necessary application permissions.

C:

This verifies a separate issue in security administration. It does not prove that the integration runs after the employee's account is disabled and unrelated API calls remain denied for the reported situation. For the Brookfield financial services firm, the direct corrective action is to create a governed application or workload identity with only the necessary application permissions.

D:

The cited result is too remote from the corrective action to create a governed application or workload identity with only the necessary application permissions. The direct evidence should show that the integration runs after the employee's account is disabled and unrelated API calls remain denied. For the Brookfield financial services firm, the direct corrective action is to create a governed application or workload identity with only the necessary application permissions.

Question 140

At the Brookfield financial services firm, a scheduled integration relies on a named employee account to call Microsoft Graph without user interaction. How should the organization sustain the improvement?

  1. Review application identity integration as cloud services are adopted
  2. Monitor registration coverage and recovery requests during deployment
  3. Practice account containment procedures during identity incident drills
  4. Rotate workload credentials and review application permissions periodically

Explanation

Correct Answer

D:

The needed prevention is to rotate workload credentials and review application permissions periodically. It directly sustains the original change to create a governed application or workload identity with only the necessary application permissions. This result addresses the stated challenge at the Brookfield financial services firm.

Incorrect Answers

A:

The option would have the team review application identity integration as cloud services are adopted. For this situation, the preventive control should instead be to rotate workload credentials and review application permissions periodically. For the Brookfield financial services firm, the direct corrective action is to create a governed application or workload identity with only the necessary application permissions.

B:

Although the proposed practice may address cases where an MFA challenge cannot succeed unless an allowed proofing method has been enrolled or provisioned, it does not maintain the specific correction here. For the Brookfield financial services firm, the direct corrective action is to create a governed application or workload identity with only the necessary application permissions.

C:

That routine supports authentication session revocation, but the relevant ongoing risk requires the team to rotate workload credentials and review application permissions periodically. For the Brookfield financial services firm, the direct corrective action is to create a governed application or workload identity with only the necessary application permissions.
