Here are the answers to Monday's CCNA, CCNP, and Network+ questions!
CCNA:
A frame comes into a switch on port fast0/1. The switch does a lookup on the destination MAC, and sees that the destination is also found off fast 0/1. What action describes how the frame will be handled?
A. unicast
B. forwarded
C. multicast
D. broadcast
E. filtered
Answer: E. If the switch detects that the source and destination are both found off the same port, the switch will filter the frame - in other words, just drop it.
Network+

CCNP / BSCI:

A VTP switch has a revision number of 5. This switch receives a VTP advertisement with a revision number of 6. What action(s) will this switch take?
A. The switch will reject the advertisement.
B. The switch will accept the advertisement.
C. The switch will increment its revision number.
D. The switch will decrement its revision number.
Answer: B, C. When a switch receives a VTP update with a revision number higher than the one it currently has, the update is accepted and the receiving switch increments its own revision number.
CCNP / BCRAN:

A. The frame switch or remote router.
B. The local router.
C. A local host.
D. One of the b-channels.
