Microsoft SC-900 Practice Test 15

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.

Question 141

At the Kingsford property management business, an Azure automation service is registered but cannot access a specific resource because its workload identity has no assignment. Which approach best resolves the identified risk?

  1. Assign the application service principal the minimum suitable authorization at the resource scope
  2. Use suitable application permissions for an approved app-only operation and govern administrator consent
  3. Require suitable user or group assignment to the enterprise application
  4. Configure Windows Hello for Business for eligible managed identities and devices

Explanation

Correct Answer

A:

The reported facts support this change rather than a general platform replacement. The team should assign the application service principal the minimum suitable authorization at the resource scope because registering an application establishes an identity but does not itself grant permission to every target resource. A suitable test confirms that the service principal performs its approved operation and receives denial for an unrelated resource. This result addresses the stated challenge at the Kingsford property management business.

Incorrect Answers

B:

The suggested action is to use suitable application permissions for an approved app-only operation and govern administrator consent, but the facts at the Kingsford property management business require a correction for the distinct problem that registering an application establishes an identity but does not itself grant permission to every target resource.

C:

This alternative would be suitable where a successful tenant sign-in does not automatically satisfy an app-specific authorization boundary. It does not by itself resolve the need to assign the application service principal the minimum suitable authorization at the resource scope. For the Kingsford property management business, the direct corrective action is to assign the application service principal the minimum suitable authorization at the resource scope.

D:

Configure Windows Hello for Business for eligible managed identities and devices addresses a different kind of problem: windows Hello for Business can use device-associated credentials unlocked by PIN or biometrics rather than submitting a reusable password to the service. Here the reported weakness is that registering an application establishes an identity but does not itself grant permission to every target resource. For the Kingsford property management business, the direct corrective action is to assign the application service principal the minimum suitable authorization at the resource scope.

Question 142

At the Kingsford property management business, an Azure automation service is registered but cannot access a specific resource because its workload identity has no assignment. Which explanation best accounts for the concern?

  1. A system-assigned managed identity is bound to a particular resource lifetime whereas a user-assigned one has its own lifecycle
  2. Password length alone does not rule out common or organization-specific guessable passwords
  3. Identity profile data alone does not explain which authentication step or access rule denied a particular sign-in
  4. Registering an application establishes an identity but does not itself grant permission to every target resource

Explanation

Correct Answer

D:

This identifies the root issue: registering an application establishes an identity but does not itself grant permission to every target resource. At the Kingsford property management business, the team should therefore assign the application service principal the minimum suitable authorization at the resource scope.

Incorrect Answers

A:

The case does not describe the failure mode involving system-assigned versus user-assigned identity. Its core issue is that registering an application establishes an identity but does not itself grant permission to every target resource. For the Kingsford property management business, the direct corrective action is to assign the application service principal the minimum suitable authorization at the resource scope.

B:

Although password length alone does not rule out common or organization-specific guessable passwords, the presented symptoms do not support that as the primary cause; they indicate that registering an application establishes an identity but does not itself grant permission to every target resource. For the Kingsford property management business, the direct corrective action is to assign the application service principal the minimum suitable authorization at the resource scope.

C:

This explanation belongs to a different security or compliance situation. In this case, the observable gap is that registering an application establishes an identity but does not itself grant permission to every target resource. For the Kingsford property management business, the direct corrective action is to assign the application service principal the minimum suitable authorization at the resource scope.

Question 143

At the Kingsford property management business, an Azure automation service is registered but cannot access a specific resource because its workload identity has no assignment. Which test result best shows the requirement is met?

  1. A test token contains the approved department claim with the correct value and no extra confidential attributes
  2. A requester's attempt to approve their own high-impact elevation is rejected under the defined policy
  3. The service principal performs its approved operation and receives denial for an unrelated resource
  4. An access review addresses membership while a separate DLP test detects the prohibited content transfer

Explanation

Correct Answer

C:

Because registering an application establishes an identity but does not itself grant permission to every target resource, the required evidence must show that the service principal performs its approved operation and receives denial for an unrelated resource. A green job status alone is insufficient. This result addresses the stated challenge at the Kingsford property management business.

Incorrect Answers

A:

This verifies a separate issue in security administration. It does not prove that the service principal performs its approved operation and receives denial for an unrelated resource for the reported situation. For the Kingsford property management business, the direct corrective action is to assign the application service principal the minimum suitable authorization at the resource scope.

B:

The cited result is too remote from the corrective action to assign the application service principal the minimum suitable authorization at the resource scope. The direct evidence should show that the service principal performs its approved operation and receives denial for an unrelated resource. For the Kingsford property management business, the direct corrective action is to assign the application service principal the minimum suitable authorization at the resource scope.

D:

At the Kingsford property management business, a result about identity governance versus data dlp would not show that the team corrected the failure where registering an application establishes an identity but does not itself grant permission to every target resource.

Question 144

At the Kingsford property management business, an Azure automation service is registered but cannot access a specific resource because its workload identity has no assignment. Which ongoing control best prevents this issue from recurring?

  1. Review application identity integration as cloud services are adopted
  2. Audit service principal role assignments when service scope changes
  3. Review risk policy response and detection coverage during security incidents
  4. Review activation logs for missing or questionable justifications

Explanation

Correct Answer

B:

The needed prevention is to audit service principal role assignments when service scope changes. It directly sustains the original change to assign the application service principal the minimum suitable authorization at the resource scope. This result addresses the stated challenge at the Kingsford property management business.

Incorrect Answers

A:

That routine supports entra cloud directory identity management, but the relevant ongoing risk requires the team to audit service principal role assignments when service scope changes. For the Kingsford property management business, the direct corrective action is to assign the application service principal the minimum suitable authorization at the resource scope.

C:

Review risk policy response and detection coverage during security incidents is not the primary recurring safeguard for this problem. The team should audit service principal role assignments when service scope changes. For the Kingsford property management business, the direct corrective action is to assign the application service principal the minimum suitable authorization at the resource scope.

D:

This is a maintenance action for a different security or compliance situation, rather than the one that originally failed because registering an application establishes an identity but does not itself grant permission to every target resource. For the Kingsford property management business, the direct corrective action is to assign the application service principal the minimum suitable authorization at the resource scope.

Question 145

At the Yorkport subscription media company, a function app embeds a long-lived client secret to access Azure Key Vault. Which implementation choice best addresses the situation?

  1. Use Microsoft Entra ID to manage tenant identities and supported cloud application authentication
  2. Enable the eligible Microsoft Authenticator passwordless sign-in method under organizational policy
  3. Inspect Microsoft Entra sign-in logs for method and policy outcome details
  4. Use a managed identity with a correctly scoped authorization for the function app

Explanation

Correct Answer

D:

The primary failure mode is that managed identities let supported Azure resources obtain tokens without handling their own stored application secrets. The proposed action directly fixes it by requiring the team to use a managed identity with a correctly scoped authorization for the function app; afterward, verify that a function successfully reads its approved secret without a client secret in application settings. This result addresses the stated challenge at the Yorkport subscription media company.

Incorrect Answers

A:

This alternative would be suitable where Entra ID supplies cloud identity and access capabilities across Microsoft and integrated applications. It does not by itself resolve the need to use a managed identity with a correctly scoped authorization for the function app. For the Yorkport subscription media company, the direct corrective action is to use a managed identity with a correctly scoped authorization for the function app.

B:

Enable the eligible Microsoft Authenticator passwordless sign-in method under organizational policy addresses a different kind of problem: supported passwordless authentication can use device-bound proof and verification rather than requiring a typed password every session. Here the reported weakness is that managed identities let supported Azure resources obtain tokens without handling their own stored application secrets. For the Yorkport subscription media company, the direct corrective action is to use a managed identity with a correctly scoped authorization for the function app.

C:

The option addresses the separate situation where identity profile data alone does not explain which authentication step or access rule denied a particular sign-in. For this case, the more appropriate response is to use a managed identity with a correctly scoped authorization for the function app. For the Yorkport subscription media company, the direct corrective action is to use a managed identity with a correctly scoped authorization for the function app.

Question 146

At the Yorkport subscription media company, a function app embeds a long-lived client secret to access Azure Key Vault. 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. Managed identities let supported Azure resources obtain tokens without handling their own stored application secrets
  3. Risk associated with a particular authentication attempt differs from the risk that an account identity itself may be compromised
  4. Authentication methods require governance over which proofs users may enroll and use

Explanation

Correct Answer

B:

This identifies the root issue: managed identities let supported Azure resources obtain tokens without handling their own stored application secrets. At the Yorkport subscription media company, the team should therefore use a managed identity with a correctly scoped authorization for the function app.

Incorrect Answers

A:

This explanation belongs to a different security or compliance situation. In this case, the observable gap is that managed identities let supported Azure resources obtain tokens without handling their own stored application secrets. For the Yorkport subscription media company, the direct corrective action is to use a managed identity with a correctly scoped authorization for the function app.

C:

The proposed cause is relevant to sign-in risk versus user risk, but it does not explain why managed identities let supported Azure resources obtain tokens without handling their own stored application secrets in the reported case. For the Yorkport subscription media company, the direct corrective action is to use a managed identity with a correctly scoped authorization for the function app.

D:

Authentication methods require governance over which proofs users may enroll and use. That is not the mechanism that accounts for the stated failure at the Yorkport subscription media company.

Question 147

At the Yorkport subscription media company, a function app embeds a long-lived client secret to access Azure Key Vault. What is the strongest acceptance test for this change?

  1. A function successfully reads its approved secret without a client secret in application settings
  2. A new cloud-only user signs into a permitted cloud app without an on-premises account
  3. A payroll sign-in without required MFA is blocked while a compliant user is granted access
  4. A security review shows a supported phishing-resistant method blocks the simulated malicious-origin sign-in

Explanation

Correct Answer

A:

Because managed identities let supported Azure resources obtain tokens without handling their own stored application secrets, the required evidence must show that a function successfully reads its approved secret without a client secret in application settings. A green job status alone is insufficient. This result addresses the stated challenge at the Yorkport subscription media company.

Incorrect Answers

B:

At the Yorkport subscription media company, a result about cloud-only versus hybrid user would not show that the team corrected the failure where managed identities let supported Azure resources obtain tokens without handling their own stored application secrets.

C:

The alternative checks whether a payroll sign-in without required MFA is blocked while a compliant user is granted access, which is not the direct acceptance criterion for the stated problem. The required result is that a function successfully reads its approved secret without a client secret in application settings. For the Yorkport subscription media company, the direct corrective action is to use a managed identity with a correctly scoped authorization for the function app.

D:

This result would validate mfa phishing resistance distinction, not the intended improvement. The needed observation is that a function successfully reads its approved secret without a client secret in application settings. For the Yorkport subscription media company, the direct corrective action is to use a managed identity with a correctly scoped authorization for the function app.

Question 148

At the Yorkport subscription media company, a function app embeds a long-lived client secret to access Azure Key Vault. Which setting or practice should be reviewed in future?

  1. Review guest access and expiration when partner engagements end
  2. Reconcile eligible and active assignments after privileged staffing changes
  3. Review managed identity permissions and resource ownership after redeployment
  4. Regularly test and monitor break-glass accounts without using them for routine administration

Explanation

Correct Answer

C:

The team should review managed identity permissions and resource ownership after redeployment. That recurring practice targets the same weakness, namely that managed identities let supported Azure resources obtain tokens without handling their own stored application secrets. This result addresses the stated challenge at the Yorkport subscription media company.

Incorrect Answers

A:

Review guest access and expiration when partner engagements end is not the primary recurring safeguard for this problem. The team should review managed identity permissions and resource ownership after redeployment. For the Yorkport subscription media company, the direct corrective action is to use a managed identity with a correctly scoped authorization for the function app.

B:

This is a maintenance action for a different security or compliance situation, rather than the one that originally failed because managed identities let supported Azure resources obtain tokens without handling their own stored application secrets. For the Yorkport subscription media company, the direct corrective action is to use a managed identity with a correctly scoped authorization for the function app.

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 Yorkport subscription media company, the direct corrective action is to use a managed identity with a correctly scoped authorization for the function app.

Question 149

At the Nortonwood property management business, a team needs one reusable workload identity across two Azure services but creates a system-assigned identity tied to only one instance. Which corrective action best meets the requirement?

  1. Use Microsoft Entra ID to manage tenant identities and supported cloud application authentication
  2. Enable Microsoft Entra self-service password reset with appropriate verification methods
  3. Use a user-assigned managed identity where a separate identity must be shared across supported resources
  4. Assign a suitable built-in read role at the smallest necessary Azure resource scope

Explanation

Correct Answer

C:

The reported facts support this change rather than a general platform replacement. The team should use a user-assigned managed identity where a separate identity must be shared across supported resources because a system-assigned managed identity is bound to a particular resource lifetime whereas a user-assigned one has its own lifecycle. A suitable test confirms that two approved services use the same user-assigned identity without sharing static passwords. This result addresses the stated challenge at the Nortonwood property management business.

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 use a user-assigned managed identity where a separate identity must be shared across supported resources. For the Nortonwood property management business, the direct corrective action is to use a user-assigned managed identity where a separate identity must be shared across supported resources.

B:

This focuses on self-service password reset; it does not directly correct the condition that a system-assigned managed identity is bound to a particular resource lifetime whereas a user-assigned one has its own lifecycle. For the Nortonwood property management business, the direct corrective action is to use a user-assigned managed identity where a separate identity must be shared across supported resources.

D:

The suggested action is to assign a suitable built-in read role at the smallest necessary Azure resource scope, but the facts at the Nortonwood property management business require a correction for the distinct problem that a system-assigned managed identity is bound to a particular resource lifetime whereas a user-assigned one has its own lifecycle.

Question 150

At the Nortonwood property management business, a team needs one reusable workload identity across two Azure services but creates a system-assigned identity tied to only one instance. Which underlying issue most directly explains this situation?

  1. User identity creation and client application registration are separate elements of an OAuth sign-in integration
  2. Not every MFA method delivers the same assurance against credential interception and phishing
  3. A system-assigned managed identity is bound to a particular resource lifetime whereas a user-assigned one has its own lifecycle
  4. Identity credentials by themselves do not evaluate the network-location risk requirement

Explanation

Correct Answer

C:

The strongest explanation is that a system-assigned managed identity is bound to a particular resource lifetime whereas a user-assigned one has its own lifecycle. This accounts for the outcome and supports the action to use a user-assigned managed identity where a separate identity must be shared across supported resources. This result addresses the stated challenge at the Nortonwood property management business.

Incorrect Answers

A:

The proposed cause is relevant to cloud application registration, but it does not explain why a system-assigned managed identity is bound to a particular resource lifetime whereas a user-assigned one has its own lifecycle in the reported case. For the Nortonwood property management business, the direct corrective action is to use a user-assigned managed identity where a separate identity must be shared across supported resources.

B:

Not every MFA method delivers the same assurance against credential interception and phishing. That is not the mechanism that accounts for the stated failure at the Nortonwood property management business.

D:

Although identity credentials by themselves do not evaluate the network-location risk requirement, the presented symptoms do not support that as the primary cause; they indicate that a system-assigned managed identity is bound to a particular resource lifetime whereas a user-assigned one has its own lifecycle. For the Nortonwood property management business, the direct corrective action is to use a user-assigned managed identity where a separate identity must be shared across supported resources.
