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

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.
