Question

When combining mutlimedia over a network

A) the network will automatically prefer data traffic over multimedia traffic
B) bursty data traffic will wait, allowing any multimedia traffic to go first
C) bursty data traffic can interfere with multimedia traffic, even if the multimedia only needs a very small amount of bandwidth
D) the network will automatically prefer mutlimedia traffic over data traffic

For multimedia On TCP/IP networks,

A) bandwidth consumption is guaranteed by the Real Time Protocol (RTP) on top of the TCP transport protocol
B) bandwidth consumption is managed with a strict quality of service (QoS) algorithm offering CBR and VBR contracts on connections
C) there are no protocols available to manage multimedia over TCP/IP
D) the Real Time Protocol (RTP) runs on top of the UDP transport protocol, which determines packet structure, time stamping and sequencing

For Skype calls

A) an open-source protocol is used
B) audio and video is sent directly between hosts, who call each other via IP address
C) a central Skype server handles login and supernodes (SNs) share IP addresses of users
D) all audio and video goes to a centralized Skype Server

Content distribution networks

A) resolve the problems of streaming stored content out to lots of simultaneous users by using distributed servers
B) resolve the issue of network bandwidth by using UDP instead of TCP
C) resolve the issue of serving videos across the network with geographically centralized servers
D) resolve the issue of network consumption by using a peer-to-peer approach
