Question 470

An engineering firm is testing desktop and browser client registrations for its inventory application. A developer needs to test which API permissions are currently configured for an app. What is the best next administrative action?

  1. Inspect the required resource access declarations and granted consent separately
  2. Register only exact supported redirect URIs with approved origins
  3. Choose app-only permissions rather than user-delegated scopes for the daemon
  4. Configure the appropriate confidential web application auth flow and credentials

Explanation

Correct Answer

A:

Requested permissions and actually consented grants can differ for the application.

Incorrect Answers

B:

Register only exact supported redirect URIs with approved origins concerns an administrator adds wildcard redirect URIs to eliminate callback errors, where redirect URI restrictions reduce authorization-response leakage to untrusted destinations; the current scenario instead requires a developer needs to test which API permissions are currently configured for an app, so Inspect the required resource access declarations and granted consent separately is a closer fit.

C:

The distinct mechanism for Choose app-only permissions rather than user-delegated scopes for the daemon is that delegated scopes require a user context; client credentials issue application-context tokens; this handles a developer attempts to use a delegated permission token from a client-credentials flow rather than a developer needs to test which API permissions are currently configured for an app, so use Inspect the required resource access declarations and granted consent separately.

D:

Although Configure the appropriate confidential web application auth flow and credentials fits a web server holds a client secret securely and requests tokens in a back-channel exchange (confidential clients can authenticate to the token endpoint in a way public clients cannot), it is not the necessary control for a developer needs to test which API permissions are currently configured for an app. Select Inspect the required resource access declarations and granted consent separately.

Question 471

A government analytics team is updating its registered identity APIs before adopting a stronger security baseline. An API still uses a broad permission scope for every operation. What configuration should be selected?

  1. Remove or deprecate the unused role only after assessing client assignments and migration
  2. Define separate delegated scopes and require the appropriate one in each API operation
  3. Split permissions into narrowly defined API scopes or roles and enforce them per endpoint
  4. Complete authorized consent in the franchise tenant for the necessary permissions

Explanation

Correct Answer

C:

Granular authorization limits a caller's reach if one permission is compromised.

Incorrect Answers

A:

Remove or deprecate the unused role only after assessing client assignments and migration concerns an obsolete app registration still exposes a privileged API app role, where legacy app roles can preserve unnecessary permission surfaces across clients; the current scenario instead requires an API still uses a broad permission scope for every operation, so Split permissions into narrowly defined API scopes or roles and enforce them per endpoint is a closer fit.

B:

The distinct mechanism for Define separate delegated scopes and require the appropriate one in each API operation is that aPI scopes provide task-specific access decisions beyond simple authenticated status; this handles an app should expose different delegated scopes to readers and report editors rather than an API still uses a broad permission scope for every operation, so use Split permissions into narrowly defined API scopes or roles and enforce them per endpoint.

D:

Complete authorized consent in the franchise tenant for the necessary permissions would support the different situation where a franchise tenant has not granted permission to the requested application API scopes: a publisher's registration does not grant API access inside every customer tenant automatically; however it does not resolve an API still uses a broad permission scope for every operation, which calls for Split permissions into narrowly defined API scopes or roles and enforce them per endpoint.

Question 472

A government analytics team is updating its registered identity APIs before adopting a stronger security baseline. An app should expose different delegated scopes to readers and report editors. Which Microsoft Entra capability best satisfies the requirement?

  1. Define separate delegated scopes and require the appropriate one in each API operation
  2. Assign new approved application owners and review its credential expiration dates
  3. Reduce requested scopes and obtain reviewed consent for the actual feature set
  4. Split permissions into narrowly defined API scopes or roles and enforce them per endpoint

Explanation

Correct Answer

A:

API scopes provide task-specific access decisions beyond simple authenticated status.

Incorrect Answers

B:

Although Assign new approved application owners and review its credential expiration dates fits a service principal owner leaves the agency and no longer maintains the integration (application registration ownership is necessary for credential lifecycle and secure operations), it is not the necessary control for an app should expose different delegated scopes to readers and report editors. Select Define separate delegated scopes and require the appropriate one in each API operation.

C:

Reduce requested scopes and obtain reviewed consent for the actual feature set would support the different situation where an external plugin requests unexpectedly broad delegated permissions during integration: user-consented scopes should align with needed delegated actions rather than convenience defaults; however it does not resolve an app should expose different delegated scopes to readers and report editors, which calls for Define separate delegated scopes and require the appropriate one in each API operation.

D:

Granular authorization limits a caller's reach if one permission is compromised, which makes Split permissions into narrowly defined API scopes or roles and enforce them per endpoint appropriate when an API still uses a broad permission scope for every operation; here the task is an app should expose different delegated scopes to readers and report editors, requiring Define separate delegated scopes and require the appropriate one in each API operation.

Question 473

A government analytics team is updating its registered identity APIs before adopting a stronger security baseline. A service principal owner leaves the agency and no longer maintains the integration. Which recommendation is most defensible?

  1. Remove or deprecate the unused role only after assessing client assignments and migration
  2. Define separate delegated scopes and require the appropriate one in each API operation
  3. Assign new approved application owners and review its credential expiration dates
  4. Reduce API permissions and scope operations using the supported granular controls

Explanation

Correct Answer

C:

Application registration ownership is necessary for credential lifecycle and secure operations.

Incorrect Answers

A:

Although Remove or deprecate the unused role only after assessing client assignments and migration fits an obsolete app registration still exposes a privileged API app role (legacy app roles can preserve unnecessary permission surfaces across clients), it is not the necessary control for a service principal owner leaves the agency and no longer maintains the integration. Select Assign new approved application owners and review its credential expiration dates.

B:

Define separate delegated scopes and require the appropriate one in each API operation would support the different situation where an app should expose different delegated scopes to readers and report editors: aPI scopes provide task-specific access decisions beyond simple authenticated status; however it does not resolve a service principal owner leaves the agency and no longer maintains the integration, which calls for Assign new approved application owners and review its credential expiration dates.

D:

When the service principal has Directory.ReadWrite.All but only needs to inspect a small identity subset, Reduce API permissions and scope operations using the supported granular controls is justified because excessively broad application grants create unnecessary tenant-wide identity exposure; here the issue is a service principal owner leaves the agency and no longer maintains the integration, and Assign new approved application owners and review its credential expiration dates addresses that distinction.

Question 474

A government analytics team is updating its registered identity APIs before adopting a stronger security baseline. An obsolete app registration still exposes a privileged API app role. Which configuration best addresses the stated requirement?

  1. Split permissions into narrowly defined API scopes or roles and enforce them per endpoint
  2. Remove unused credentials and retire the registration after checking dependencies
  3. Assign new approved application owners and review its credential expiration dates
  4. Remove or deprecate the unused role only after assessing client assignments and migration

Explanation

Correct Answer

D:

Legacy app roles can preserve unnecessary permission surfaces across clients.

Incorrect Answers

A:

Split permissions into narrowly defined API scopes or roles and enforce them per endpoint would support the different situation where an API still uses a broad permission scope for every operation: granular authorization limits a caller's reach if one permission is compromised; however it does not resolve an obsolete app registration still exposes a privileged API app role, which calls for Remove or deprecate the unused role only after assessing client assignments and migration.

B:

Abandoned app identities can preserve usable secrets even after the visible application is gone, which makes Remove unused credentials and retire the registration after checking dependencies appropriate when the legacy application registration has no active clients but retains live credentials; here the task is an obsolete app registration still exposes a privileged API app role, requiring Remove or deprecate the unused role only after assessing client assignments and migration.

C:

When a service principal owner leaves the agency and no longer maintains the integration, Assign new approved application owners and review its credential expiration dates is justified because application registration ownership is necessary for credential lifecycle and secure operations; here the issue is an obsolete app registration still exposes a privileged API app role, and Remove or deprecate the unused role only after assessing client assignments and migration addresses that distinction.

Question 475

A telecommunications operator builds a service-to-service application that uses certificates and Microsoft Graph. A certificate assertion receives an invalid-client error after a renewal. Which change most directly satisfies the scenario?

  1. Verify consented application permissions and the service principal's granted app roles
  2. Check that the new certificate public key is registered and the correct key signs assertions
  3. Configure a supported application certificate credential with rotation controls
  4. Use a federated credential tied to a trusted external workload identity

Explanation

Correct Answer

B:

Certificate credential validation requires the registration and private key to correspond.

Incorrect Answers

A:

Merely requesting a permission in registration does not supply an effective tenant consent grant, which makes Verify consented application permissions and the service principal's granted app roles appropriate when an application token lacks the Graph role despite a requested permission; here the task is a certificate assertion receives an invalid-client error after a renewal, requiring Check that the new certificate public key is registered and the correct key signs assertions.

C:

Configure a supported application certificate credential with rotation controls concerns the service can authenticate using certificate-based client assertions, where a certificate assertion can replace a plain shared secret when securely managed; the current scenario instead requires a certificate assertion receives an invalid-client error after a renewal, so Check that the new certificate public key is registered and the correct key signs assertions is a closer fit.

D:

The distinct mechanism for Use a federated credential tied to a trusted external workload identity is that workload federation exchanges identity assertions without storing a persistent client secret; this handles a team wants an automatic way to avoid long-lived app secrets in supported CI builds rather than a certificate assertion receives an invalid-client error after a renewal, so use Check that the new certificate public key is registered and the correct key signs assertions.

Question 476

A telecommunications operator builds a service-to-service application that uses certificates and Microsoft Graph. An application token lacks the Graph role despite a requested permission. What is the best next administrative action?

  1. Use proper token validation and credential proof; treat the client ID as public metadata
  2. Complete authorized consent in the franchise tenant for the necessary permissions
  3. Verify consented application permissions and the service principal's granted app roles
  4. Use a federated credential tied to a trusted external workload identity

Explanation

Correct Answer

C:

Merely requesting a permission in registration does not supply an effective tenant consent grant.

Incorrect Answers

A:

When a developer wants to treat the app client ID as a secret for access control, Use proper token validation and credential proof; treat the client ID as public metadata is justified because an application ID identifies the client but cannot authenticate it by itself; here the issue is an application token lacks the Graph role despite a requested permission, and Verify consented application permissions and the service principal's granted app roles addresses that distinction.

B:

Complete authorized consent in the franchise tenant for the necessary permissions concerns a franchise tenant has not granted permission to the requested application API scopes, where a publisher's registration does not grant API access inside every customer tenant automatically; the current scenario instead requires an application token lacks the Graph role despite a requested permission, so Verify consented application permissions and the service principal's granted app roles is a closer fit.

D:

Although Use a federated credential tied to a trusted external workload identity fits a team wants an automatic way to avoid long-lived app secrets in supported CI builds (workload federation exchanges identity assertions without storing a persistent client secret), it is not the necessary control for an application token lacks the Graph role despite a requested permission. Select Verify consented application permissions and the service principal's granted app roles.

Question 477

A telecommunications operator builds a service-to-service application that uses certificates and Microsoft Graph. A team wants an automatic way to avoid long-lived app secrets in supported CI builds. Which option is most appropriate for this specific condition?

  1. Use a federated credential tied to a trusted external workload identity
  2. Inspect the app registration manifest and authentication settings
  3. Check that the new certificate public key is registered and the correct key signs assertions
  4. Use proper token validation and credential proof; treat the client ID as public metadata

Explanation

Correct Answer

A:

Workload federation exchanges identity assertions without storing a persistent client secret.

Incorrect Answers

B:

The distinct mechanism for Inspect the app registration manifest and authentication settings is that app registration metadata documents the protocol configuration independently of enterprise service principal assignments; this handles the team wants the application name and redirect URIs visible during audit review rather than a team wants an automatic way to avoid long-lived app secrets in supported CI builds, so use Use a federated credential tied to a trusted external workload identity.

C:

Although Check that the new certificate public key is registered and the correct key signs assertions fits a certificate assertion receives an invalid-client error after a renewal (certificate credential validation requires the registration and private key to correspond), it is not the necessary control for a team wants an automatic way to avoid long-lived app secrets in supported CI builds. Select Use a federated credential tied to a trusted external workload identity.

Question 478

A telecommunications operator builds a service-to-service application that uses certificates and Microsoft Graph. A developer wants to treat the app client ID as a secret for access control. What configuration should be selected?

  1. Use proper token validation and credential proof; treat the client ID as public metadata
  2. Verify consented application permissions and the service principal's granted app roles
  3. Configure the appropriate confidential web application auth flow and credentials
  4. Check that the new certificate public key is registered and the correct key signs assertions

Explanation

Correct Answer

A:

An application ID identifies the client but cannot authenticate it by itself.

Incorrect Answers

B:

Although Verify consented application permissions and the service principal's granted app roles fits an application token lacks the Graph role despite a requested permission (merely requesting a permission in registration does not supply an effective tenant consent grant), it is not the necessary control for a developer wants to treat the app client ID as a secret for access control. Select Use proper token validation and credential proof; treat the client ID as public metadata.

C:

Configure the appropriate confidential web application auth flow and credentials would support the different situation where a web server holds a client secret securely and requests tokens in a back-channel exchange: confidential clients can authenticate to the token endpoint in a way public clients cannot; however it does not resolve a developer wants to treat the app client ID as a secret for access control, which calls for Use proper token validation and credential proof; treat the client ID as public metadata.

D:

Certificate credential validation requires the registration and private key to correspond, which makes Check that the new certificate public key is registered and the correct key signs assertions appropriate when a certificate assertion receives an invalid-client error after a renewal; here the task is a developer wants to treat the app client ID as a secret for access control, requiring Use proper token validation and credential proof; treat the client ID as public metadata.

Question 479

A global publisher is consolidating duplicate app registrations that were created for the same editorial portal. Two client app registrations use overlapping display names but different object and application IDs. Which recommendation is most defensible?

  1. Reduce requested scopes and obtain reviewed consent for the actual feature set
  2. Inventory app IDs, service principals, redirects and permission grants before consolidating
  3. Remove unused credentials and retire the registration after checking dependencies
  4. Register the correct web redirect URI in the app's authentication configuration

Explanation

Correct Answer

B:

Human-readable names do not identify protocol clients reliably enough for safe migration.

Incorrect Answers

A:

Although Reduce requested scopes and obtain reviewed consent for the actual feature set fits an external plugin requests unexpectedly broad delegated permissions during integration (user-consented scopes should align with needed delegated actions rather than convenience defaults), it is not the necessary control for two client app registrations use overlapping display names but different object and application IDs. Select Inventory app IDs, service principals, redirects and permission grants before consolidating.

C:

Abandoned app identities can preserve usable secrets even after the visible application is gone, which makes Remove unused credentials and retire the registration after checking dependencies appropriate when the legacy application registration has no active clients but retains live credentials; here the task is two client app registrations use overlapping display names but different object and application IDs, requiring Inventory app IDs, service principals, redirects and permission grants before consolidating.

D:

When the web client must redirect authorization responses to one verified application callback, Register the correct web redirect URI in the app's authentication configuration is justified because strict redirect URI matching prevents tokens or authorization codes being returned to arbitrary endpoints; here the issue is two client app registrations use overlapping display names but different object and application IDs, and Inventory app IDs, service principals, redirects and permission grants before consolidating addresses that distinction.

Question 480

A global publisher is consolidating duplicate app registrations that were created for the same editorial portal. A migration changed the registered redirect URI and users receive a callback mismatch. Which configuration best addresses the stated requirement?

  1. Remove unused credentials and retire the registration after checking dependencies
  2. Align the callback URI with the exact supported app authentication configuration
  3. Register only exact supported redirect URIs with approved origins
  4. Inventory app IDs, service principals, redirects and permission grants before consolidating

Explanation

Correct Answer

B:

OAuth redirect URI validation protects the authorization response destination.

Incorrect Answers

A:

Remove unused credentials and retire the registration after checking dependencies would support the different situation where the legacy application registration has no active clients but retains live credentials: abandoned app identities can preserve usable secrets even after the visible application is gone; however it does not resolve a migration changed the registered redirect URI and users receive a callback mismatch, which calls for Align the callback URI with the exact supported app authentication configuration.

C:
