  1. the correct answer are B & E :

    B. voice service voip
    no ip address trusted authenticate
    mode border-element
    allow-connections sip to sip

    E. voice service voip
    mode border-element
    ip address trusted list
    ipv4 10.1.1.0 255.255 255.0
    ipv4 10.3.1.0 255.255.255.0
    allow-connections sip to sip
    sip

    you can configure only one under voice service Voip of the router, but both of them are correct.
