Here are the answers to yesterday's Cisco certification training questions!
CCNA:
Host A and Host B are in VLAN 1. Host C and Host D are in VLAN 10. Host A sends a broadcast. How many other hosts will receive it?
A. None of them
B. One
C. Two
D. Three
Answer: B. When a host in a VLAN sends a broadcast, only other hosts in that same VLAN will receive it. In this case, that's Host B.
CCNP / BSCI:
What exit interface will traffic destined for 210.1.1.1 use, according to this routing table excerpt?
O 210.1.1.0 /24 [110 / 20] via ethernet0
R 210.1.1.0/24 [120/3] via ethernet1
I 210.1.1.0/25 [100/2] via serial0
D EX 210.1.1.0/23 [90/4899390] via serial1
Answer: Serial0. The first criteria examined by the routing engine is prefix length. All four paths match the destination, but the IGRP path has the longest prefix length (/25). The IGRP path, using Serial0 as the exit interface, will be used.
CCNP / BCMSN:
Which of the following will reset a switch's revision number back to zero?
A. Erase the vlan.dat file and reload the switch.
B. Change the VTP domain name to a nonexistent domain, then switch it back.
C. Power the switch down, wait one minute, and enter the BREAK sequence when reloading.
D. Change the VTP mode to Transparent and then back to server.
Answers: B, D. To reset the revision number, change the VTP domain name to a nonexistent one and then change it back, or change the mode from Transparent to Server and then back again. A reload won't do it.
I warn you in advance that this is one of those things that sometimes works better in theory than it does in practice. :) But make sure to get it done!
See you later today with more Cisco certification questions, links, and more!
To your success,
