Explanation
The default VoIP dial peer on Cisco IOS has the following characteristics: (B) RSVP (Resource Reservation Protocol) is not supported by default - it must be explicitly configured; (D) Both G.711 and G.729 codecs are supported by default, meaning the router will negotiate either codec during call setup; (E) Fax-rate service is supported by default, allowing fax calls to be handled. VAD (Voice Activity Detection) is actually ENABLED by default on VoIP dial peers (making option A false). DTMF relay is NOT enabled by default - it must be explicitly configured (making option F false). Only G.711 being supported (option C) is incorrect because G.729 is also included in the default codec list.
