Oracle Communications Session Border Controller — Question 22

When setting up the registration-caching parameter to enabled in the sip-interface configuration element, _____________.

Answer options

• A. the Session Border Controller will never use the SIP-NAT mechanism for routing
• B. the Session Border Controller will not use the registration cache for routing
• C. all endpoints in the realm will be cached when registered
• D. only endpoints behind NAT in the realm will be cached when registered
• E. the Session Border Controller will never use the local-policy mechanism for routing

Correct answer: A

Explanation

The correct answer is A because enabling the registration-caching parameter disables the SIP-NAT mechanism, ensuring that the Session Border Controller routes calls without relying on NAT. The other options are incorrect because they either misinterpret the behavior of the registration cache or the implications of enabling the parameter.
