Users have been complaining that their Frame Relay connection to the corporate site is very
slow. The network administrator suspects that the link is overloaded.

Based on the partial output of the Router# show frame relay pvc command shown in the
graphic, which output value indicates to the local router that traffic sent to the corporate site
is experiencing congestion?

A.
DLCI = 100

B.
last time PVC status changed 00:25:40

C.
in BECN packets 192

D.
in FECN packets 147

E.
in DE packets 0

Explanation:
If device A is sending data to device B across a Frame Relay infrastructure and one of the
intermediate Frame Relay switches encounters congestion, congestion being full buffers,
over-subscribed port, overloaded resources, etc, it will set the BECN bit on packets being
returned to the sending device and the FECN bit on the packets being sent to the receiving
device.
