a)
The video that is streamed directly from web server to media player will use TCP as the underlying protocol.
Hence the given statement is “True”.
b)
The user is capable of changing the encoding in the middle of the session to change the payload type of the RTP stream.
Hence the given statement is “True”.
c)
The application that uses the RTP can use any port to send and receive through any port numbers.
Hence, the given statement is “False”.
d)
The session that has a separate audio and video stream for each sender, the audio and video streams uses different SSRC.
Hence, the statement is “False”.
e)
Per-hop behavior defines the difference in the performance among the classes of traffic present in the diffserv network.
Hence, the given statement is “True”.
f)
According to the example given in the text, Alice indicates that the message to receive the audio from the bob.
Hence the given statement is “False”.
g)
According to the example given in the text, Alice indicates that the message to receive the audio from the bob through the port 48753.
Hence the given statement is “False”.
h)
The messages between the SIP entities are transmitted through a default port number 5060.
Hence the given statement is “True”.
i)
The SIP registration process is made using the REGISTER. Registration is the first step for making VOIP (Voice Over Internet Protocol).
Hence the given statement is “True”.
j)
H.323 mandates the G.711 audio encoding and the given is not the requirement of the SIP.
Hence the given statement is “False”.
