Question 2

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

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

Answer: C

Question 3

After configuring Header Manipulation Rules (HMRs) for topology hiding, your subsequent testing shows that the manipulation is not takingeffect. Identify two causes for this (Choose two.)

Options :

A :

You have not configured the out-manipulationid parameter of the sip-interface configuration element.

B : You have not enabled policy-based realm-bridging

C :

The value of the name parameter in the header-rule configuration element is different than the value of the out-manipulationid parameter in the sip-interface configuration element.

D : The value of the match-val-type parameter is not written correctly

E :

The home-proxy-address value does not matchthe $LOCAL_IP value in the new-value parameter.

Answer: A,E
