Here are the answers to Saturday morning's Cisco CCNA and CCNP practice questions!

CCNA:

Host A wants to transmit data to Host B. Host A knows Host B's IP address, but not its MAC address. Two routers and a hub separate the hosts. What protocol will allow Host A to successfully transmit data to Host B?

A. ARP

B. Proxy ARP

C. Inverse ARP

D. Reverse ARP

Answer: B. Host A will send an ARP Request, but since there's a router between the two hosts, Host B will not receive it because routers don't forward broadcasts. The router will instead answer the ARP Request with the MAC address of the ethernet interface that received the ARP request - that's Proxy ARP in operation.


CCNP / BSCI:By default, how does an OSPF routing table indicate routes that were learned by the OSPF domain via redistribution?

A. O E2

B. O E1

C. O EX

D. O EX *

E. O IA

F. O IA *

Answer: A. The route will be marked as OSPF External Type-2, or E2.


CCNP / BCMSN:

A switch's priority is at is default setting, and it has a MAC address of aa-aa-aa-aa-aa-aa. What is this switch's BID in the root bridge election? (Short answer)

Answer: 32768:aa-aa-aa-aa-aa-aa

CCNP / BCRAN:

Where will such attributes as the Bc and CIR be defined when Frame Relay Traffic Shaping is in use?

A. Under the appropriate serial interface.

B. Globally.

C. Under the appropriate routing protocol.

D. In a map class.

E. In a distribute-list.

F. In a prefix-list.

Answer: D. The actual values are set in a map class, and the map class is then applied to the appropriate interface or virtual circuits.


CCNP / CIT:The traceroute you just started running is returning only asterisks. Problem is, they just keep coming and coming. What is the escape sequence for a traceroute?

A. ctrl-shift-del

B. ctrl-shift-6, ctrl-shift-6

C. ctrl-shift-6, x

D. ctrl-shift-break

E. ctrl-break

Answer: B. To terminate a traceroute or ping, just press twice.
