Question 410

A healthcare provider is limiting administrative control over its clinical enterprise applications. An application is accidentally available to all signed-in users after initial integration. Which configuration best addresses the stated requirement?

  1. Assign an approved enterprise application owner and verify their management scope
  2. Route the permission request through the authorized admin-consent review process
  3. Require explicit user assignment and restrict allowed groups
  4. Review provisioning deactivation behavior and the app's supported deprovisioning integration

Explanation

Correct Answer

C:

Authentication to Entra does not alone guarantee an application should admit every tenant user.

Incorrect Answers

A:

When the hospital needs an application owner accountable for certificate renewals and integration changes, Assign an approved enterprise application owner and verify their management scope is justified because ownership creates a governed point of responsibility without making every engineer Global Administrator; here the issue is an application is accidentally available to all signed-in users after initial integration, and Require explicit user assignment and restrict allowed groups addresses that distinction.

B:

Route the permission request through the authorized admin-consent review process concerns a new SaaS app requests tenant-wide consent for directory read permissions, where tenant-wide consent can expose data across users and needs deliberate approval of the requested scopes; the current scenario instead requires an application is accidentally available to all signed-in users after initial integration, so Require explicit user assignment and restrict allowed groups is a closer fit.

D:

Although Review provisioning deactivation behavior and the app's supported deprovisioning integration fits a former employee retains a SaaS account after being removed from all Entra groups (access revocation needs both directory authorization cleanup and target account lifecycle treatment), it is not the necessary control for an application is accidentally available to all signed-in users after initial integration. Select Require explicit user assignment and restrict allowed groups.

Question 411

A banking organization is reviewing old enterprise applications after several vendor migrations. A former vendor's enterprise app is no longer used but retains active assignments. Which change most directly satisfies the scenario?

  1. Review application-scoped sign-in logs and relevant usage evidence
  2. Change the relevant enterprise app assignment and SSO controls for access management
  3. Decommission the app's access, provisioning and tokens under the approved retirement plan
  4. Start from the supported enterprise gallery app and validate the vendor-specific claims

Explanation

Correct Answer

C:

Unused service principals and assignments can preserve unnecessary routes to data.

Incorrect Answers

A:

Review application-scoped sign-in logs and relevant usage evidence concerns the team must identify which staff still accessed the legacy application last month, where sign-in evidence identifies actual use rather than relying solely on assigned-user counts; the current scenario instead requires a former vendor's enterprise app is no longer used but retains active assignments, so Decommission the app's access, provisioning and tokens under the approved retirement plan is a closer fit.

B:

The distinct mechanism for Change the relevant enterprise app assignment and SSO controls for access management is that the enterprise service principal is the runtime app instance; deletion of the developer registration is a different action; this handles an engineer tries to delete the registration instead of adjusting the enterprise app's user assignment rather than a former vendor's enterprise app is no longer used but retains active assignments, so use Decommission the app's access, provisioning and tokens under the approved retirement plan.

D:

Start from the supported enterprise gallery app and validate the vendor-specific claims would support the different situation where a vendor SaaS already provides an Entra gallery template for SAML: a maintained integration template reduces manual setup but still requires explicit validation; however it does not resolve a former vendor's enterprise app is no longer used but retains active assignments, which calls for Decommission the app's access, provisioning and tokens under the approved retirement plan.

Question 412

A banking organization is reviewing old enterprise applications after several vendor migrations. The team must identify which staff still accessed the legacy application last month. What is the best next administrative action?

  1. Review the service principal's permission grants and approved publisher context
  2. Review application-scoped sign-in logs and relevant usage evidence
  3. Rotate the signing certificate through coordinated identity provider and service provider configuration
  4. Decommission the app's access, provisioning and tokens under the approved retirement plan

Explanation

Correct Answer

B:

Sign-in evidence identifies actual use rather than relying solely on assigned-user counts.

Incorrect Answers

A:

The distinct mechanism for Review the service principal's permission grants and approved publisher context is that consent grants can outlive active user assignments and create separate application exposure; this handles the team needs to identify whether an old enterprise app still carries sensitive API consent grants rather than the team must identify which staff still accessed the legacy application last month, so use Review application-scoped sign-in logs and relevant usage evidence.

C:

Rotate the signing certificate through coordinated identity provider and service provider configuration would support the different situation where a migrated app's SAML certificate expires next week: both trust endpoints must agree on accepted signing credentials during certificate rollover; however it does not resolve the team must identify which staff still accessed the legacy application last month, which calls for Review application-scoped sign-in logs and relevant usage evidence.

D:

Unused service principals and assignments can preserve unnecessary routes to data, which makes Decommission the app's access, provisioning and tokens under the approved retirement plan appropriate when a former vendor's enterprise app is no longer used but retains active assignments; here the task is the team must identify which staff still accessed the legacy application last month, requiring Review application-scoped sign-in logs and relevant usage evidence.

Question 413

A banking organization is reviewing old enterprise applications after several vendor migrations. A migrated app's SAML certificate expires next week. Which option is most appropriate for this specific condition?

  1. Change the relevant enterprise app assignment and SSO controls for access management
  2. Repair the target app provisioning credential and verify the next synchronization cycle
  3. Rotate the signing certificate through coordinated identity provider and service provider configuration
  4. Review application-scoped sign-in logs and relevant usage evidence

Explanation

Correct Answer

C:

Both trust endpoints must agree on accepted signing credentials during certificate rollover.

Incorrect Answers

A:

Although Change the relevant enterprise app assignment and SSO controls for access management fits an engineer tries to delete the registration instead of adjusting the enterprise app's user assignment (the enterprise service principal is the runtime app instance; deletion of the developer registration is a different action), it is not the necessary control for a migrated app's SAML certificate expires next week. Select Rotate the signing certificate through coordinated identity provider and service provider configuration.

B:

Repair the target app provisioning credential and verify the next synchronization cycle would support the different situation where the enterprise app's provisioning account has expired and all user updates stop: provisioning requires a valid target API connection independently of SSO; however it does not resolve a migrated app's SAML certificate expires next week, which calls for Rotate the signing certificate through coordinated identity provider and service provider configuration.

D:

When the team must identify which staff still accessed the legacy application last month, Review application-scoped sign-in logs and relevant usage evidence is justified because sign-in evidence identifies actual use rather than relying solely on assigned-user counts; here the issue is a migrated app's SAML certificate expires next week, and Rotate the signing certificate through coordinated identity provider and service provider configuration addresses that distinction.

Question 414

A banking organization is reviewing old enterprise applications after several vendor migrations. An engineer tries to delete the registration instead of adjusting the enterprise app's user assignment. What configuration should be selected?

  1. Decommission the app's access, provisioning and tokens under the approved retirement plan
  2. Rotate the signing certificate through coordinated identity provider and service provider configuration
  3. Require user assignment and assign the approved payroll group to the enterprise app
  4. Change the relevant enterprise app assignment and SSO controls for access management

Explanation

Correct Answer

D:

The enterprise service principal is the runtime app instance; deletion of the developer registration is a different action.

Incorrect Answers

A:

Decommission the app's access, provisioning and tokens under the approved retirement plan would support the different situation where a former vendor's enterprise app is no longer used but retains active assignments: unused service principals and assignments can preserve unnecessary routes to data; however it does not resolve an engineer tries to delete the registration instead of adjusting the enterprise app's user assignment, which calls for Change the relevant enterprise app assignment and SSO controls for access management.

B:

Both trust endpoints must agree on accepted signing credentials during certificate rollover, which makes Rotate the signing certificate through coordinated identity provider and service provider configuration appropriate when a migrated app's SAML certificate expires next week; here the task is an engineer tries to delete the registration instead of adjusting the enterprise app's user assignment, requiring Change the relevant enterprise app assignment and SSO controls for access management.

C:

When only the payroll department should be able to launch the SaaS application, Require user assignment and assign the approved payroll group to the enterprise app is justified because application assignment restricts authorized users independently of successful tenant authentication; here the issue is an engineer tries to delete the registration instead of adjusting the enterprise app's user assignment, and Change the relevant enterprise app assignment and SSO controls for access management addresses that distinction.

Question 415

A public university must publish internal administrative sites to staff outside the campus network. Only the admissions web app should be reachable remotely under Entra MFA. Which recommendation is most defensible?

  1. Validate Kerberos constrained delegation and service principal name requirements
  2. Repair connector-side DNS and backend network reachability
  3. Publish admissions through Application Proxy and scope Conditional Access to the enterprise app
  4. Block or restrict the app under the approved access governance process

Explanation

Correct Answer

C:

Proxy publishing and access policy combine reachability with controlled user authentication.

Incorrect Answers

A:

Backend Windows SSO depends on correct Kerberos identity and delegation configuration, which makes Validate Kerberos constrained delegation and service principal name requirements appropriate when external staff need seamless integrated Windows sign-in after Entra preauthentication; here the task is only the admissions web app should be reachable remotely under Entra MFA, requiring Publish admissions through Application Proxy and scope Conditional Access to the enterprise app.

B:

When the application proxy connector cannot resolve the internal service hostname, Repair connector-side DNS and backend network reachability is justified because a healthy Entra policy cannot compensate for missing internal DNS resolution; here the issue is only the admissions web app should be reachable remotely under Entra MFA, and Publish admissions through Application Proxy and scope Conditional Access to the enterprise app addresses that distinction.

D:

The distinct mechanism for Block or restrict the app under the approved access governance process is that unreviewed SaaS integrations should not receive broad identity or consent rights; this handles one cloud app is shadow IT and has not undergone a security review rather than only the admissions web app should be reachable remotely under Entra MFA, so use Publish admissions through Application Proxy and scope Conditional Access to the enterprise app.

Question 416

A public university must publish internal administrative sites to staff outside the campus network. The application proxy connector cannot resolve the internal service hostname. Which configuration best addresses the stated requirement?

  1. Validate Kerberos constrained delegation and service principal name requirements
  2. Inspect connector health, network resolution and the internal application URL
  3. Repair connector-side DNS and backend network reachability
  4. Use the approved application proxy path and remove unnecessary direct Internet exposure

Explanation

Correct Answer

C:

A healthy Entra policy cannot compensate for missing internal DNS resolution.

Incorrect Answers

A:

When external staff need seamless integrated Windows sign-in after Entra preauthentication, Validate Kerberos constrained delegation and service principal name requirements is justified because backend Windows SSO depends on correct Kerberos identity and delegation configuration; here the issue is the application proxy connector cannot resolve the internal service hostname, and Repair connector-side DNS and backend network reachability addresses that distinction.

B:

Inspect connector health, network resolution and the internal application URL concerns users are redirected to the proxy but receive backend connection failures, where preauthentication success does not prove an on-premises connector can reach the backend server; the current scenario instead requires the application proxy connector cannot resolve the internal service hostname, so Repair connector-side DNS and backend network reachability is a closer fit.

D:

Although Use the approved application proxy path and remove unnecessary direct Internet exposure fits an IT worker exposes a direct public NAT mapping to the app rather than using the connector (direct public reachability bypasses the intended Entra-aware application access boundary), it is not the necessary control for the application proxy connector cannot resolve the internal service hostname. Select Repair connector-side DNS and backend network reachability.

Question 417

A public university must publish internal administrative sites to staff outside the campus network. External staff need seamless integrated Windows sign-in after Entra preauthentication. What should the identity administrator implement?

  1. Review application-scoped sign-in logs and relevant usage evidence
  2. Require explicit user assignment and restrict allowed groups
  3. Publish admissions through Application Proxy and scope Conditional Access to the enterprise app
  4. Validate Kerberos constrained delegation and service principal name requirements

Explanation

Correct Answer

D:

Backend Windows SSO depends on correct Kerberos identity and delegation configuration.

Incorrect Answers

A:

Review application-scoped sign-in logs and relevant usage evidence concerns the team must identify which staff still accessed the legacy application last month, where sign-in evidence identifies actual use rather than relying solely on assigned-user counts; the current scenario instead requires external staff need seamless integrated Windows sign-in after Entra preauthentication, so Validate Kerberos constrained delegation and service principal name requirements is a closer fit.

B:

The distinct mechanism for Require explicit user assignment and restrict allowed groups is that authentication to Entra does not alone guarantee an application should admit every tenant user; this handles an application is accidentally available to all signed-in users after initial integration rather than external staff need seamless integrated Windows sign-in after Entra preauthentication, so use Validate Kerberos constrained delegation and service principal name requirements.

C:

Although Publish admissions through Application Proxy and scope Conditional Access to the enterprise app fits only the admissions web app should be reachable remotely under Entra MFA (proxy publishing and access policy combine reachability with controlled user authentication), it is not the necessary control for external staff need seamless integrated Windows sign-in after Entra preauthentication. Select Validate Kerberos constrained delegation and service principal name requirements.

Question 418

A public university must publish internal administrative sites to staff outside the campus network. An IT worker exposes a direct public NAT mapping to the app rather than using the connector. Which change most directly satisfies the scenario?

  1. Inspect connector health, network resolution and the internal application URL
  2. Use the approved application proxy path and remove unnecessary direct Internet exposure
  3. Repair connector-side DNS and backend network reachability
  4. Configure supported Kerberos constrained delegation for single sign-on where appropriate

Explanation

Correct Answer

B:

Direct public reachability bypasses the intended Entra-aware application access boundary.

Incorrect Answers

A:

The distinct mechanism for Inspect connector health, network resolution and the internal application URL is that preauthentication success does not prove an on-premises connector can reach the backend server; this handles users are redirected to the proxy but receive backend connection failures rather than an IT worker exposes a direct public NAT mapping to the app rather than using the connector, so use Use the approved application proxy path and remove unnecessary direct Internet exposure.

C:

Repair connector-side DNS and backend network reachability would support the different situation where the application proxy connector cannot resolve the internal service hostname: a healthy Entra policy cannot compensate for missing internal DNS resolution; however it does not resolve an IT worker exposes a direct public NAT mapping to the app rather than using the connector, which calls for Use the approved application proxy path and remove unnecessary direct Internet exposure.

D:

Application Proxy can translate identity to a supported on-premises Windows authentication path with proper delegation, which makes Configure supported Kerberos constrained delegation for single sign-on where appropriate appropriate when the app already trusts Windows integrated authentication after the proxy connector; here the task is an IT worker exposes a direct public NAT mapping to the app rather than using the connector, requiring Use the approved application proxy path and remove unnecessary direct Internet exposure.

Question 419

An enterprise is implementing OIDC SSO for a SaaS content management system used by employees. The SaaS vendor supports OpenID Connect with redirect URI and client settings. Which option is most appropriate for this specific condition?

  1. Add the gallery enterprise application and configure the vendor's required SSO settings
  2. Assign and emit suitable application roles or claims for the app's supported authorization model
  3. Use approved credential handling and rotate any exposed secret immediately
  4. Configure the enterprise SSO integration using the vendor's supported OpenID Connect flow

Explanation

Correct Answer

D:

OIDC sign-in requires correct redirect endpoints, token audience, and issuer trust.

Incorrect Answers

A:

Although Add the gallery enterprise application and configure the vendor's required SSO settings fits a new SaaS application has a supported gallery integration template (gallery templates can provide predefined integration properties but still need correct tenant-specific configuration), it is not the necessary control for the SaaS vendor supports OpenID Connect with redirect URI and client settings. Select Configure the enterprise SSO integration using the vendor's supported OpenID Connect flow.

B:

Assign and emit suitable application roles or claims for the app's supported authorization model would support the different situation where the app needs different authorization for editors and viewers after login: identity authentication does not define which in-app operations a user may perform; however it does not resolve the SaaS vendor supports OpenID Connect with redirect URI and client settings, which calls for Configure the enterprise SSO integration using the vendor's supported OpenID Connect flow.

C:

Application secrets are reusable credentials and require confidential distribution and lifecycle controls, which makes Use approved credential handling and rotate any exposed secret immediately appropriate when a vendor wants a client secret emailed in plaintext to help debug SSO; here the task is the SaaS vendor supports OpenID Connect with redirect URI and client settings, requiring Configure the enterprise SSO integration using the vendor's supported OpenID Connect flow.

Question 420

An enterprise is implementing OIDC SSO for a SaaS content management system used by employees. A sign-in request fails because its redirect URI differs from the registered value. What configuration should be selected?

  1. Check the SAML signing certificate and service-provider trust configuration
  2. Correct the registered redirect URI to match the application's supported callback
  3. Use approved credential handling and rotate any exposed secret immediately
  4. Validate Kerberos constrained delegation and service principal name requirements

Explanation

Correct Answer

B:

Redirect URI matching prevents an authorization response from going to an arbitrary destination.

Incorrect Answers

A:

Check the SAML signing certificate and service-provider trust configuration would support the different situation where the SaaS fails signature validation even though user authentication in Entra succeeds: sAML consumers validate signing trust independently from the user's password verification; however it does not resolve a sign-in request fails because its redirect URI differs from the registered value, which calls for Correct the registered redirect URI to match the application's supported callback.

C:

When a vendor wants a client secret emailed in plaintext to help debug SSO, Use approved credential handling and rotate any exposed secret immediately is justified because application secrets are reusable credentials and require confidential distribution and lifecycle controls; here the issue is a sign-in request fails because its redirect URI differs from the registered value, and Correct the registered redirect URI to match the application's supported callback addresses that distinction.

D:

Validate Kerberos constrained delegation and service principal name requirements concerns external staff need seamless integrated Windows sign-in after Entra preauthentication, where backend Windows SSO depends on correct Kerberos identity and delegation configuration; the current scenario instead requires a sign-in request fails because its redirect URI differs from the registered value, so Correct the registered redirect URI to match the application's supported callback is a closer fit.
