Which content sharing protocol is negotiated for point-to-point meetings in a Cisco TelePresence environment
with H.323?

A.
BFCP

B.
H.239

C.
Auto-Collaborate

D.
Switched Presentation

Explanation:
239 is negotiated for point-to-point meetings in a Cisco TelePresence environment with H.323. Content sharing
protocols use a separate content channel to enable endpoints to display presentation materials and participants
simultaneously.
Binary Floor Control Protocol (BFCP) is negotiated for point-to-point meetings in a Cisco TelePresence
environment with Session Initiation Protocol (SIP). Auto-Collaborate is negotiated for point-to-point and
multipoint meetings in a Cisco TelePresence environment with TelePresence Interoperability Protocol (TIP). If a
content-sharing protocol cannot be negotiated, Switched Presentation can be used. However, when a
participant is displaying presentation materials, only the presentation materials will be displayed; the participant
will not be displayed.
