Here are the answers to Wednesday night's Cisco CCNA and CCNP practice questions!
CCNA:
What statements are true of fragment-free switching?
A. There is virtually no error checking.
B. There is some error checking.
C. The switch looks only at the destination MAC address before beginning to forward the frame.
D. The switch looks at the first 64 bytes before beginning to forward the frame.
Answer: B, D. The "middle ground" of switching mode, fragment-free switching provides some error checking by verifying the first 64 bytes of the frame, which is where most errors occur.
CCNP / BCSI:
You enter the following two statements into your router. What is the result?
Router(config)#ip route 172.1.1.1 255.255.255.255 fast0
Router(config)#ip route 172.1.1.1 255.255.255.255 210.1.1.1
A. The first ip route statement will be entered into the routing table.
B. The second ip route statement will be entered into the routing table.
C. Both routes will be entered into the routing table.
D. Neither route will be entered into the routing table.
Answer: A. The first statement will be entered into the routing table. The prefix lengths are the same, but the first static route to 172.1.1.1 has an AD of 0, since it uses a local exit interface. The second route, using a next-hop IP address, will have an AD of 1. The lowest AD is preferred if the prefix lengths are the same.
CCNP / BCRAN:What VPN service allows a data receiver to guarantee the packet source?
A. data origin authentication
B. data security
C. data integrity
D. encryption
E. data authorization
F. data accounting
Answer: A. That's data origin authentication.
CCNP / BCMSN:
For what purpose is VMPS used?
A. creation of dynamic VLANs
B. dynamic VTP server assignments
C. enables the switch to dynamically locate TFTP servers
D. dynamic discovery of non-connected switches
Answer: A. VMPS (VLAN Membership Policy Server) creates dynamic VLANs.
CCNP / CIT:
The following is the initial output of what Cisco routing troubleshooting command? Short answer, no choices given.
R1#xxxxxxxxx
IP statistics: Rcvd: 0 total, 0 local destination
0 format errors, 0 checksum errors, 0 bad hop count
0 unknown protocol, 0 not a gateway
0 security failures, 0 bad options, 0 with options
Opts: 0 end, 0 nop, 0 basic security, 0 loose source route
0 timestamp, 0 extended security, 0 record route
0 stream ID, 0 strict source route, 0 alert, 0 cipso, 0 ump
0 other Frags: 0 reassembled, 0 timeouts, 0 couldn't reassemble
0 fragmented, 0 couldn't fragment Bcast: 0 received, 3 sent
Mcast: 0 received, 0 sent Sent: 2 generated, 0 forwarded Drop: 1 encapsulation failed, 0 unresolved, 0 no adjacency 0 no route, 0 unicast RPF, 0 forced drop
Answer: This mouthful is just the beginning of the output of show ip traffic.
See you later tonight with Thursday night's CCNA and CCNP practice questions!
