You need to configure the BCS model to access data. What should you do?

The correct answer is B. Create an external content type and enter the target application ID in the Secure Store Application ID field. BCS external content types require the exact Secure Store target application ID - not the friendly name - to retrieve stored credentials for external data access.

Why each option

BCS external content types require the exact Secure Store target application ID - not the friendly name - to retrieve stored credentials for external data access.

ACreate an external content type and enter the target application friendly name in the Secure Store Application ID field.

The Secure Store Application ID field requires the target application ID, not its friendly display name, so entering the friendly name causes the credential lookup to fail.

BCreate an external content type and enter the target application ID in the Secure Store Application ID field.Correct

When configuring an external content type in SharePoint Designer, the Secure Store Application ID field must contain the precise target application ID as defined in the Secure Store Service, which is a case-sensitive unique identifier. BCS uses this ID at runtime to look up and retrieve the stored credentials for authenticating against the external system. Using the application ID rather than the friendly name ensures the credential lookup succeeds during data operations.

CCreate an external content type and choose the Connect with impersonated custom identity option.

The 'Connect with impersonated custom identity' option is a different authentication mode and does not represent the standard Secure Store target application ID mapping for BCS.

DCreate an external content type and choose the Connect with user's identity option.

The 'Connect with user's identity' option passes through the authenticated user's Windows credentials via Kerberos delegation and does not use Secure Store credentials at all.
