A.
Permanent

B.
Virtual

C.
Temporary

D.
Shared

Explanation:
Circuit switching establishes physical, permanent connections from the
time a call begins to the time it ends. The connection is not shared; it is a
private end-to-end connection that is built when a call goes up and torn down when
the call ends.

  1. John Gleason says:

    By your own definition this is a temporary connection.
    “from the time a call begins to the time it ends”
    I presume it is built for this puroose and torn down again after. At a minimum a poorly worded question.

    I don’t like this one at all. Not sure where the Explanation quote came from, but it is very ambiguous. There is nothing permanent about either type. Temporary would be a much better option. Dedicated is what Shon Harris uses:

    “Circuit switching sets up a virtual connection that acts like a dedicated link between two systems.The channel remains configured at the original devices until the call, or connection, is done and torn down.

    Packet switching, on the other hand, does not set up a dedicated virtual link, and packets from one connection can pass through a number of different individual devices (see the top of Figure 7-49), instead of all of them following one another through the same devices.”

    The question could have been worded better, Say “For circuit switched connections, information flow from the origin to destination:-
    A. Follows the same through the entire duration of connect
    B. Can follow multiple paths.
    C. Is along a dynamic path.
    D. Is along a non-unique path.
