Answer: C, B, A, and D
The correct order of the four steps used in establishing an
X.25 virtual circuit are as follows:
1.)The source DTE sends packet to the local DCE
2.)The local DCE packet binder sends packet to the closest
PSE (Packet Switch Exchange)
3.)The PSE (Packet Switch Exchange) passes the packet to the
next remote DCE
4.)The remote DCE examines the packet header of destination
DTE
