Q21. You must decide whether to deploy the policy based realm bridging with header manipulation rules (PBRB-HMR) model in your SIP peering environment.
What are two deciding factors that tip your decision for or against HMR in contrast to a SIP-NAT Bridge (SNB) architecture?
A. PBRB-HMR has lower performance overhead than SIP-NAT Bridge.
B. PBRB-HMR is much easier to configure, even though it has similar performance to the SNB model.
C. PBRB-HMR is recommended for both peering and access architectures.
D. SNB is the simplest model to troubleshoot.
E. PBRB-HMR provides better topology hiding, at the expense of performance.
