Selected Answer: BD

B. Authentication credentials can be stored in the local database of the Expressway: This is true. Expressway can store authentication credentials locally for endpoints that register with it. D. The endpoint and Expressway must be configured and synchronized with an NTP server delivering an identical time stamp: Time synchronization via NTP (Network Time Protocol) is critical for secure communications, including authentication, as it ensures that timestamps used in authentication protocols are accurate.
