Oracle Communications Session Border Controller — Question 52

What is the first thing you should do when you want the Session Border Controller to detect that an endpoint is behind a NAT/firewall device?

Answer options

• A. Navigate to the sip-port configuration element and set the nat-traversal parameter to disabled.
• B. Navigate to the sip-interface configuration element and set the nat-traversal parameter to never.
• C. Navigate to the sip-interface configuration element and set the nat-traversal parameter to always.
• D. Navigate to the sip-port configuration element and set the nat-traversal parameter to enabled.
• E. Navigate to the sip-interface configuration element and set the nat-traversal parameter to detect.

Correct answer: C

Explanation

The correct answer is C because setting the nat-traversal parameter to 'always' allows the Session Border Controller to consistently recognize endpoints behind NAT/firewalls. The other options either disable NAT traversal or do not enable it sufficiently, thus preventing proper detection.
