It's Friday, September 12, and here are the answers to Thursday's CCNA, CCNP, and CCENT practice exam qustions.

CCNA Wireless and Voice questions return on Monday!



CCNA Certification And CCENT Certification:

What purposes do the BECN, FECN, and DE bits in Frame Relay serve?

Answer: When a frame arrives at a router with the FECN bit set, that means congestion was encountered in the direction in which the frame was traveling.


When a frame arrives at a router with the BECN bit set, congestion was encountered in the opposite direction in which the frame was traveling.

Frames are sometimes dropped as a result of congestion, and frames with the DE bit set will be dropped before frames without that bit set. Basically, setting the DE bit on a frame indicates data that's considered less important than data without the DE bit set.
