Oracle Communications Session Border Controller — Question 7

What does the Session Border Controller do when the Adaptive Hosted NAT (HNT) feature is enabled?

Answer options

• A. It sends a periodic re-register command to each endpoint behind a NAT.
• B. It creates a binding for the Address of Record (AOR) of an endpoint that is behind a NAT.
• C. It creates a binding for the Address of Record (AOR) of an endpoint that is NOT behind a NAT.
• D. It sends SIP OPTIONS at increasing intervals to test if an endpoint behind a NAT device is still reachable.
• E. It sends ICMP PNGs to dynamically learn the binding time of an endpoint behind a NAT device.

Correct answer: C

Explanation

The correct answer is C because when the Adaptive Hosted NAT feature is enabled, the Session Border Controller creates a binding for the Address of Record (AOR) of endpoints that are not behind a NAT. Options A, B, D, and E are incorrect as they describe actions related to NAT endpoints or incorrect functionalities that do not align with the purpose of the HNT feature.
