Which two items must be provided by the user to add an external data source...

Adding an external data source to a data object in Pega requires specific details to ensure proper integration and functionality:

A. The authenticating information, if required by the corresponding service. Secure access to external data services often requires authentication details, such as API keys or login credentials, to ensure that interactions are authorized.

D. The uniform resource identifier that identifies the web service. The URI is crucial as it specifies the exact location and endpoint of the web service from which data is to be fetched, acting as a link between the Pega application and the external data source.
