Which of the following content-sharing protocols cannot display meeting participants and presentation materials
simultaneously?

A.
BFCP

B.
H.239

C.
Auto-Collaborate

D.
Switched Presentation

Explanation:
Switched Presentation cannot display meeting participants and presentation materials simultaneously. Binary
Floor Control Protocol (BFCP), H.239, and Auto-Collaborate are content-sharing protocols that use a separate
content channel to enable endpoints to display presentation materials and participants simultaneously.
When Session Initiation Protocol (SIP) is used in a Cisco TelePresence environment, BFCP is negotiated for
point-to-point meetings. When H.323 is used in a Cisco TelePresence environment, H.239 is negotiated for
point-to-point meetings. When TelePresence Interoperability Protocol (TIP) is used in a Cisco TelePresence
environment, Auto-Collaborate is negotiated for point-to-point and multipoint meetings. If a content-sharing
protocol cannot be negotiated, Switched Presentation can be used.
