Microsoft SC-300 Practice Test 29

Question 280

A SaaS vendor registers one multitenant application, while a customer needs an independently controllable local identity for enterprise app assignments. The proposed change is: Use the vendor's app registration for the application definition and consent-created customer-tenant service principal for local administration. After applying the intended configuration, which observation most directly proves that the required behavior works?

  1. Inspect the production token's identity and run a permitted target-resource request from the deployed environment.
  2. Run a pod using the approved service account and verify its acquired identity can retrieve only the authorized secret.
  3. Delete a disposable test VM after inspecting its identity, and verify the associated system-assigned service principal lifecycle.
  4. Inspect the shared application client ID and distinct tenant-specific service principal object IDs.

Explanation

Correct Answer

D:

Inspect the shared application client ID and distinct tenant-specific service principal object IDs. This directly tests the effective outcome, not merely that a configuration exists. It establishes whether the intended change works: use the vendor's app registration for the application definition and consent-created customer-tenant service principal for local administration. Failure would be evident in this case: a customer admin searches only App registrations and cannot find the installed third-party application's local access assignments.

Incorrect Answers

A:

The proposed observation checks the different defaultazurecredential workload use scenario. Even a successful test would not establish the requested outcome here: inspect the shared application client ID and distinct tenant-specific service principal object IDs.

B:

The proposed observation checks the different aks workload identity service account scenario. Even a successful test would not establish the requested outcome here: inspect the shared application client ID and distinct tenant-specific service principal object IDs.

C:

The proposed observation checks the different system-assigned managed identity lifetime scenario. Even a successful test would not establish the requested outcome here: inspect the shared application client ID and distinct tenant-specific service principal object IDs.

Question 281

A customer admin searches only App registrations and cannot find the installed third-party application's local access assignments. Which root cause best explains the described result rather than merely treating its symptoms?

  1. The credential provider selection was bound to local development identity rather than the deployed managed identity.
  2. User-targeted Conditional Access and workload identity policies have different eligible target types.
  3. Resource recreation changed the system-assigned identity; a user-assigned identity would retain a stable separate principal.
  4. The vendor owns the app registration in its home tenant; the customer manages the local enterprise application service principal.

Explanation

Correct Answer

D:

The vendor owns the app registration in its home tenant; the customer manages the local enterprise application service principal. This is the causal explanation of the observed behavior: a customer admin searches only App registrations and cannot find the installed third-party application's local access assignments. Address the underlying mechanism with: use the vendor's app registration for the application definition and consent-created customer-tenant service principal for local administration. Then confirm: inspect the shared application client ID and distinct tenant-specific service principal object IDs.

Incorrect Answers

A:

This diagnosis fits a separate defaultazurecredential workload use incident: Production fails because code accidentally depends on a local developer CLI credential not present on the VM. It does not explain this case's observed failure; the vendor owns the app registration in its home tenant; the customer manages the local enterprise application service principal.

B:

This diagnosis fits a separate workload identity conditional access incident: A client-credential application keeps authenticating despite a Conditional Access policy aimed only at human users. It does not explain this case's observed failure; the vendor owns the app registration in its home tenant; the customer manages the local enterprise application service principal.

C:

This diagnosis fits a separate user-assigned managed identity reuse incident: After replacing an app instance the service stops accessing data because a new system-assigned principal lacks the previous role grants. It does not explain this case's observed failure; the vendor owns the app registration in its home tenant; the customer manages the local enterprise application service principal.

Question 282

A SaaS vendor registers one multitenant application, while a customer needs an independently controllable local identity for enterprise app assignments. The initial implementation works. Which continuing control most directly prevents the same failure or drift from recurring?

  1. Test token principal and credential source in each environment and avoid relying on workstation state.
  2. Document application versus service-principal object IDs before modifying consent or assignments.
  3. Maintain an inventory of shared user-assigned identity consumers and remove access when the last consumer retires.
  4. Use bounded deployment retries and record actual effective authorization before reporting the rollout complete.

Explanation

Correct Answer

B:

Document application versus service-principal object IDs before modifying consent or assignments. This reduces future drift after the initial control is deployed: use the vendor's app registration for the application definition and consent-created customer-tenant service principal for local administration. Recheck the actual behavior with: inspect the shared application client ID and distinct tenant-specific service principal object IDs.

Incorrect Answers

A:

This control manages future defaultazurecredential workload use drift, but it does not reduce the continuing exposure in the described app registration and enterprise service principal case. The correct safeguard is: document application versus service-principal object IDs before modifying consent or assignments.

C:

This control manages future user-assigned managed identity reuse drift, but it does not reduce the continuing exposure in the described app registration and enterprise service principal case. The correct safeguard is: document application versus service-principal object IDs before modifying consent or assignments.

D:

This control manages future managed identity role propagation drift, but it does not reduce the continuing exposure in the described app registration and enterprise service principal case. The correct safeguard is: document application versus service-principal object IDs before modifying consent or assignments.

Question 283

A service principal needs noninteractive authentication protected by policies applicable to workload identities, not user MFA challenges. Which proposed configuration or implementation directly meets the stated requirement?

  1. Configure supported Conditional Access policies for workload identities targeting eligible service principals and available conditions.
  2. Use the vendor's app registration for the application definition and consent-created customer-tenant service principal for local administration.
  3. Configure supported AKS Workload Identity federation between its Kubernetes service account and a scoped Microsoft Entra identity.
  4. Configure a workload identity federated credential for the approved GitHub issuer, audience and subject, then use token exchange.

Explanation

Correct Answer

A:

Configure supported Conditional Access policies for workload identities targeting eligible service principals and available conditions. The solution acts at the intended identity, policy or application scope. A successful result is testable: check the service principal sign-in logs and relevant Conditional Access evaluation on a controlled workload authentication. The competing configuration error is: user-targeted Conditional Access and workload identity policies have different eligible target types.

Incorrect Answers

B:

That action implements the separate app registration and enterprise service principal decision. It is appropriate when a SaaS vendor registers one multitenant application, while a customer needs an independently controllable local identity for enterprise app assignments. The present case instead requires the specific workload identity conditional access change: configure supported Conditional Access policies for workload identities targeting eligible service principals and available conditions.

C:

That action implements the separate aks workload identity service account decision. It is appropriate when an AKS deployment needs a pod to access Azure Key Vault using a specific identity without mounting a client secret into the container. The present case instead requires the specific workload identity conditional access change: configure supported Conditional Access policies for workload identities targeting eligible service principals and available conditions.

D:

That action implements the separate github oidc federated credential decision. It is appropriate when a GitHub Actions workflow deploys Azure infrastructure from one approved repository and branch with no stored long-lived app secret. The present case instead requires the specific workload identity conditional access change: configure supported Conditional Access policies for workload identities targeting eligible service principals and available conditions.

Question 284

A service principal needs noninteractive authentication protected by policies applicable to workload identities, not user MFA challenges. The proposed change is: Configure supported Conditional Access policies for workload identities targeting eligible service principals and available conditions. After applying the intended configuration, which observation most directly proves that the required behavior works?

  1. Inspect the shared application client ID and distinct tenant-specific service principal object IDs.
  2. Delete a disposable test VM after inspecting its identity, and verify the associated system-assigned service principal lifecycle.
  3. Run a pod using the approved service account and verify its acquired identity can retrieve only the authorized secret.
  4. Check the service principal sign-in logs and relevant Conditional Access evaluation on a controlled workload authentication.

Explanation

Correct Answer

D:

Check the service principal sign-in logs and relevant Conditional Access evaluation on a controlled workload authentication. This directly tests the effective outcome, not merely that a configuration exists. It establishes whether the intended change works: configure supported Conditional Access policies for workload identities targeting eligible service principals and available conditions. Failure would be evident in this case: a client-credential application keeps authenticating despite a Conditional Access policy aimed only at human users.

Incorrect Answers

A:

The proposed observation checks the different app registration and enterprise service principal scenario. Even a successful test would not establish the requested outcome here: check the service principal sign-in logs and relevant Conditional Access evaluation on a controlled workload authentication.

B:

The proposed observation checks the different system-assigned managed identity lifetime scenario. Even a successful test would not establish the requested outcome here: check the service principal sign-in logs and relevant Conditional Access evaluation on a controlled workload authentication.

C:

The proposed observation checks the different aks workload identity service account scenario. Even a successful test would not establish the requested outcome here: check the service principal sign-in logs and relevant Conditional Access evaluation on a controlled workload authentication.

Question 285

A client-credential application keeps authenticating despite a Conditional Access policy aimed only at human users. Which root cause best explains the described result rather than merely treating its symptoms?

  1. The Kubernetes service account subject or workload identity annotation does not match the configured federated credential.
  2. Resource recreation changed the system-assigned identity; a user-assigned identity would retain a stable separate principal.
  3. User-targeted Conditional Access and workload identity policies have different eligible target types.
  4. The vendor owns the app registration in its home tenant; the customer manages the local enterprise application service principal.

Explanation

Correct Answer

C:

User-targeted Conditional Access and workload identity policies have different eligible target types. This is the causal explanation of the observed behavior: a client-credential application keeps authenticating despite a Conditional Access policy aimed only at human users. Address the underlying mechanism with: configure supported Conditional Access policies for workload identities targeting eligible service principals and available conditions. Then confirm: check the service principal sign-in logs and relevant Conditional Access evaluation on a controlled workload authentication.

Incorrect Answers

A:

This diagnosis fits a separate aks workload identity service account incident: Pods running under the default Kubernetes service account cannot exchange tokens for the designated Entra identity. It does not explain this case's observed failure; user-targeted Conditional Access and workload identity policies have different eligible target types.

B:

This diagnosis fits a separate user-assigned managed identity reuse incident: After replacing an app instance the service stops accessing data because a new system-assigned principal lacks the previous role grants. It does not explain this case's observed failure; user-targeted Conditional Access and workload identity policies have different eligible target types.

D:

This diagnosis fits a separate app registration and enterprise service principal incident: A customer admin searches only App registrations and cannot find the installed third-party application's local access assignments. It does not explain this case's observed failure; user-targeted Conditional Access and workload identity policies have different eligible target types.

Question 286

A service principal needs noninteractive authentication protected by policies applicable to workload identities, not user MFA challenges. The initial implementation works. Which continuing control most directly prevents the same failure or drift from recurring?

  1. Maintain an inventory of shared user-assigned identity consumers and remove access when the last consumer retires.
  2. Bind permitted Kubernetes service accounts tightly and audit namespace and service-account changes.
  3. Inventory privileged service principals and review relevant workload policies and license prerequisites.
  4. Review subject and audience claim constraints when repositories, environments or branches change.

Explanation

Correct Answer

C:

Inventory privileged service principals and review relevant workload policies and license prerequisites. This reduces future drift after the initial control is deployed: configure supported Conditional Access policies for workload identities targeting eligible service principals and available conditions. Recheck the actual behavior with: check the service principal sign-in logs and relevant Conditional Access evaluation on a controlled workload authentication.

Incorrect Answers

A:

This control manages future user-assigned managed identity reuse drift, but it does not reduce the continuing exposure in the described workload identity conditional access case. The correct safeguard is: inventory privileged service principals and review relevant workload policies and license prerequisites.

B:

This control manages future aks workload identity service account drift, but it does not reduce the continuing exposure in the described workload identity conditional access case. The correct safeguard is: inventory privileged service principals and review relevant workload policies and license prerequisites.

D:

This control manages future github oidc federated credential drift, but it does not reduce the continuing exposure in the described workload identity conditional access case. The correct safeguard is: inventory privileged service principals and review relevant workload policies and license prerequisites.

Question 287

A CI pipeline has the correct federated issuer and subject, but Microsoft Entra rejects token exchange because the external token audience differs. Which proposed configuration or implementation directly meets the stated requirement?

  1. Configure a workload identity federated credential for the approved GitHub issuer, audience and subject, then use token exchange.
  2. Align the federated identity credential's expected audience with the valid external workload token audience.
  3. Account for role assignment propagation and obtain a fresh authorized token as appropriate while confirming the role/scope is correct.
  4. Configure supported AKS Workload Identity federation between its Kubernetes service account and a scoped Microsoft Entra identity.

Explanation

Correct Answer

B:

Align the federated identity credential's expected audience with the valid external workload token audience. The solution acts at the intended identity, policy or application scope. A successful result is testable: decode a test token's issuer, subject and audience claims and verify a successful token exchange. The competing configuration error is: the federated credential audience does not match the JWT aud claim.

Incorrect Answers

A:

That action implements the separate github oidc federated credential decision. It is appropriate when a GitHub Actions workflow deploys Azure infrastructure from one approved repository and branch with no stored long-lived app secret. The present case instead requires the specific federated credential audience mismatch change: align the federated identity credential's expected audience with the valid external workload token audience.

C:

That action implements the separate managed identity role propagation decision. It is appropriate when an Azure Automation job using its managed identity is granted a new RBAC role, but the next immediate API call still fails. The present case instead requires the specific federated credential audience mismatch change: align the federated identity credential's expected audience with the valid external workload token audience.

D:

That action implements the separate aks workload identity service account decision. It is appropriate when an AKS deployment needs a pod to access Azure Key Vault using a specific identity without mounting a client secret into the container. The present case instead requires the specific federated credential audience mismatch change: align the federated identity credential's expected audience with the valid external workload token audience.

Question 288

A CI pipeline has the correct federated issuer and subject, but Microsoft Entra rejects token exchange because the external token audience differs. The proposed change is: Align the federated identity credential's expected audience with the valid external workload token audience. After applying the intended configuration, which observation most directly proves that the required behavior works?

  1. Delete a disposable test VM after inspecting its identity, and verify the associated system-assigned service principal lifecycle.
  2. Use its token to list or read the permitted blob and verify an unrelated container remains unavailable.
  3. Decode a test token's issuer, subject and audience claims and verify a successful token exchange.
  4. Run a pod using the approved service account and verify its acquired identity can retrieve only the authorized secret.

Explanation

Correct Answer

C:

Decode a test token's issuer, subject and audience claims and verify a successful token exchange. This directly tests the effective outcome, not merely that a configuration exists. It establishes whether the intended change works: align the federated identity credential's expected audience with the valid external workload token audience. Failure would be evident in this case: a valid branch-restricted workload token fails even though its issuer and subject match the app's credential.

Incorrect Answers

A:

The proposed observation checks the different system-assigned managed identity lifetime scenario. Even a successful test would not establish the requested outcome here: decode a test token's issuer, subject and audience claims and verify a successful token exchange.

B:

The proposed observation checks the different managed identity azure rbac authorization scenario. Even a successful test would not establish the requested outcome here: decode a test token's issuer, subject and audience claims and verify a successful token exchange.

D:

The proposed observation checks the different aks workload identity service account scenario. Even a successful test would not establish the requested outcome here: decode a test token's issuer, subject and audience claims and verify a successful token exchange.

Question 289

A valid branch-restricted workload token fails even though its issuer and subject match the app's credential. Which root cause best explains the described result rather than merely treating its symptoms?

  1. Possessing a managed identity token does not itself grant the Storage Blob Data Reader data action.
  2. The federated credential does not restrict the GitHub repository and branch subject as intended.
  3. The Kubernetes service account subject or workload identity annotation does not match the configured federated credential.
  4. The federated credential audience does not match the JWT aud claim.

Explanation

Correct Answer

D:

The federated credential audience does not match the JWT aud claim. This is the causal explanation of the observed behavior: a valid branch-restricted workload token fails even though its issuer and subject match the app's credential. Address the underlying mechanism with: align the federated identity credential's expected audience with the valid external workload token audience. Then confirm: decode a test token's issuer, subject and audience claims and verify a successful token exchange.

Incorrect Answers

A:

This diagnosis fits a separate managed identity azure rbac authorization incident: Token acquisition succeeds but Blob data reads return authorization failure. It does not explain this case's observed failure; the federated credential audience does not match the JWT aud claim.

B:

This diagnosis fits a separate github oidc federated credential incident: An unapproved branch can obtain tokens because the federated identity subject was configured too broadly. It does not explain this case's observed failure; the federated credential audience does not match the JWT aud claim.

C:

This diagnosis fits a separate aks workload identity service account incident: Pods running under the default Kubernetes service account cannot exchange tokens for the designated Entra identity. It does not explain this case's observed failure; the federated credential audience does not match the JWT aud claim.

Question 290

A CI pipeline has the correct federated issuer and subject, but Microsoft Entra rejects token exchange because the external token audience differs. The initial implementation works. Which continuing control most directly prevents the same failure or drift from recurring?

  1. Test token principal and credential source in each environment and avoid relying on workstation state.
  2. Track identity type and deletion semantics during VM retirement so orphaned independent identities are reviewed.
  3. Test federated assertion claims as a set during identity-provider updates rather than weakening subject restrictions.
  4. Review subject and audience claim constraints when repositories, environments or branches change.

Explanation

Correct Answer

C:

Test federated assertion claims as a set during identity-provider updates rather than weakening subject restrictions. This reduces future drift after the initial control is deployed: align the federated identity credential's expected audience with the valid external workload token audience. Recheck the actual behavior with: decode a test token's issuer, subject and audience claims and verify a successful token exchange.

Incorrect Answers

A:

This control manages future defaultazurecredential workload use drift, but it does not reduce the continuing exposure in the described federated credential audience mismatch case. The correct safeguard is: test federated assertion claims as a set during identity-provider updates rather than weakening subject restrictions.

B:

This control manages future system-assigned managed identity lifetime drift, but it does not reduce the continuing exposure in the described federated credential audience mismatch case. The correct safeguard is: test federated assertion claims as a set during identity-provider updates rather than weakening subject restrictions.

D:

This control manages future github oidc federated credential drift, but it does not reduce the continuing exposure in the described federated credential audience mismatch case. The correct safeguard is: test federated assertion claims as a set during identity-provider updates rather than weakening subject restrictions.
