Oracle Communications Session Border Controller — Question 32

What is the drawback of configuring Policy-Based Realm Bridging (PBRB) without the assistance of Header Manipulation Rules (HMRs)?

Answer options

• A. Topology hiding is incomplete.
• B. The configuration requires a home realm to be defined, which can make privacy harder to achieve.
• C. The configuration requires you to enable SIP-NAT bridging, which is complex.
• D. The architecture is simple, and really designed for lab environments.
• E. The performance is poor relative to other models.

Correct answer: C

Explanation

The correct answer is C because enabling SIP-NAT bridging introduces complexity to the configuration process. While options A, B, D, and E mention various issues, they do not directly address the specific challenges that arise from the requirement of SIP-NAT bridging when HMRs are not used.
