With which type of service is bandwidth and latency the biggest consideration?
A.
streaming video
B.
telnet sessions
C.
FTP transfers
D.
authentication traffic
Explanation:
Streaming video places the largest demand on both bandwidth and latency. Video traffic is real-time and
benefits from dedicated bandwidth with QoS implementation to ensure quality. Moreover, this service can
tolerate very little latency.Telnet and FTP sessions are both low bandwidth users and can tolerate a high degree of latency since the data
can be reassembled when all pieces arrive, which is not possible when data is coming in real-time, and waiting
for retransmissions and reassembly is not feasible.
Authentication traffic is not sensitive to latency and does not require much bandwidth either.
