Here are the answers to Tuesday's CCNA, CCNP, and Network+ exam questions!
CCNA:
You forgot to include the broadcast option on your frame map statements. Which of the following protocols will have difficulty sending updates over the frame cloud?
A. RIPv1
B. RIPv2
C. IGRP
D. EIGRP
E. OSPF
Answer: A, B, C, D, E. Whether they use broadcasts or multicasts, none of those protocols will be able to successfully send updates over frame relay if the broadcast option is left off the frame map statement. (Pings would have no problem, since they're not broadcasts or multicasts.)
Network+ :
Identify the true statements regarding IPSec and L2TP.
A. They both run at the Data Link layer.
B. They both run at the Network layer.
C. IPSec runs at the Network layer, L2TP runs at the Data Link layer.
D. L2TP runs at the Network layer, IPSec runs at the Data Link layer.
Answer: They're both security protocols, but L2TP runs at the Data Link layer and IP Sec runs at the Network layer.
CCNP / BSCI:
A BGP router has two possible paths to a remote destination. The weights are unchanged. What is the next deciding factor?
A. The path with the highest LOCAL_PREF will be preferred.
B. The path with the lowest LOCAL_PREF will be preferred.
C. The path with the shortest AS_PATH will be preferred.
D. The path with the longest AS_PATH will be preferred.
Answer: A. After weight, LOCAL_PREF is the next attribute measured, and the highest value is preferred.
CCNP / BCMSN:
By default, in what trunking mode do ports on a 2950 run?
A. dynamic auto
B. on
C. dynamic desirable
D. unconditional
Answer: C. They're all in dynamic desirable by default, which means they are actively attempting to trunk.
CCNP / BCRAN:
Dialer map statements contain an IP address and a phone number. Who do these belong to?
A. Both belong to the remote router.
B. Both belong to the local router.
C. The IP address belongs to the local router, the phone number to the remote router.
D. The IP address belongs to the remote router, the phone number to the local router.
Answer: A. Dialer map statements always contain the other router's IP address and the other router's phone number. Remember it this way - if you wanted to call someone else, you wouldn't dial your own number, right? :)
CCNP / CIT:
In a frame map statement, what is true regarding the DLCI and IP address?
A. The DLCI belongs to the local router.
B. The DLCI belongs to the remote router.
C. The IP address belongs to the local router.
D. The IP address belongs to the remote router.
Answer: A, D. I put this question here with the above dialer map question on purpose, since an occasional student will get them mixed up. Just remember...
Frame map statements: Local router's DLCI, remote router's IP address
Dialer map statements: Remote router's phone number, remote router's IP address
See you later today with Thursday's practice questions, and don't forget -- just 11 days until my Network+ Study Package comes out, followed in early November by the one everyone's waiting for - the Security+ Study Package.
