Which of the following is not true of a circuit-switched network?

A.
Acts as a dedicate virtual connection

B.
Is connection-oriented

C.
Usually carries voice traffic

D.
Has variable delays

Explanation:
Because connections must be established and terminated with each
session, there are predictable and fixed delays with circuit-switched networks.
Packet-switching connections will have variable delays because the packets can take
different paths and be queued at different intermediate devices.
