est your knowledge of ARP, Proxy ARP, administrative distance, and other vital Cisco exam topics with these free questions!

CCNA And CCENT Certification Exam:

Host A wants to send data to Host B. Host A knows Host B's IP address, but not its MAC address. There are two switches and a hub between the two hosts. What protocol will allow Host A to transmit data successfully to Host B?

B. Inverse ARP

C. RARP

D. Proxy ARP

Answer: A. ARP can work successfully in this situation, since there are no routers in the path between Host A and Host B. ARP broadcasts will successfully be forwarded by the switches.

CCNP Certification / BSCI Exam:

Given the following routing table excerpt, what local interface will traffic destined for 234.4.4.4 use to exit the router?

R 234.4.4.0 /24 [120/2] via ethernet0

I 234.4.4.0 /23 [100/4253] via ethernet1

R 234.4.4.0 /24 [120/2] via serial0

O 234.4.4.0 /23 [110/20]via serial1

Answer: The load will be shared over the two RIP paths. They have the longest prefix for the route (/24), and since the metrics are equal, they will equal-cost load-share over the two paths. Hopefully you'll only see a routing table like that on an exam or here in a practice question!

CCNP Certification / BCMSN Exam:

Short answer: You want to connect a router's AUI port to a switch port. What kind of cable will you need?
