Q
How is Permanent Virtual Circuit (PVC) established?
AA. It can be established by transporting packets in the sequence in which they were transmitted by the source along the same path for a given session
BB. It can be established by grouping a number of virtual circuits between two switches into a virtual path
CC. . when the connection is established for long periods of time and not switched between sessions, a permanent virtual circuit (pvc) is established. advertisement
DD. It can be established on a per session basis or on a permanent basis between a pair of end stations that carry large volumes of traffic
Correct Answer:
C. C. . when the connection is established for long periods of time and not switched between sessions, a permanent virtual circuit (pvc) is established. advertisement
Explanation:
The VP- VC can be established on a per session basis or on a permanent basis between a pair of end stations that carry large volumes of traffic. In the former ease, the circuit is established as and when needed and torn down after the session is over. This is called the switched virtual circuit (SVC). When the connection is established for long periods of time and not switched between sessions, a permanent virtual circuit (PVC) is established.
