Which procedure uses H.225 messages to exchange H.245 Master-Salve Determination
information?
A.
H.323 Fast Connect
B.
H.245 tunneling
C.
H.225 tunneling
D.
H.323 early media
E.
H.245 terminal capability set
Explanation:
The H.245 protocol is a media control protocol that is a part of H.323 protocol suite.
The H.245 protocol is used primarily to negotiate master-slave relationship between
communicating endpoints. These endpoints exchange terminal capabilities and logical channel
manipulations (open, close, modify).The H.245 messages can be encapsulated and carried
between H.225 controlled endpoints within H.225 messages. This way of “piggy-backing” an
H.245 message to H.225 message is referred to as H245 Tunneling. The H.245 Tunneling method
is optional and negotiable between communicating H.323 endpoints. If both endpoints support this
option, usually the H.245 Media Controlled messages are exchanged via the Tunneling method.
