Cisco Video Infrastructure Implementation — Question 8

Which two statements about endpoint registration authentication are true? (Choose two.)

Answer options

• A. When a subzone is set for "Treat as Authenticated", the endpoint must have the correct authentications configured
• B. Authentication credentials can be stored in the local database of the Expressway
• C. Expressways and endpoints do not need to be synchronized with identical NTP timestamps
• D. The endpoint and Expressway must be configured and synchronized with an NTP server delivering an identical time stamp
• E. SIP endpoints always need authentication credentials

Correct answer: A, E

Explanation

Option A is correct because if a subzone is marked as 'Treat as Authenticated', proper authentication configurations are essential for the endpoint. Option E is also correct, as SIP endpoints indeed require authentication credentials to establish secure connections. Options B, C, and D are incorrect; B is not universally true for all configurations, C is false because synchronization is necessary for proper operation, and D is a requirement rather than an option.
