Cisco Systems manual 121

640 - 607

Answer: A

Explanation: When Inverse ARP is not supported by a remote router, or when you want to control broadcast traffic when using routing, you must define the address-to-DCLI table statically. These entries are referred to as static maps.

Incorrect Answers:

B is incorrect; defining an IP address would not have the desired effect.

C is incorrect; DHCP can’t provide a mapping to a remote Frame Relay router.

D is incorrect; reverse ARP is used to map IP addresses to the DLCI, and is not a routing issue.

Q. 195

You are configuring a Frame Relay Router with subinterfaces on interface Serial 0. Which subinterface number could you use for this configuration?

A.1 and 2.

B.0.2 and 0.3

C.1 and 1.1

D.0.1a and 0.1b.

Answer: B

Explanation:

When you configure a subinterface you use the interface {typenumber.suberinterfeace-number} command. As you are configuring serial interface O the command would be:

interface ethernet 0.1 (where 0 indicate the interface and .1 indicates the first subinterface.) This would be followed be a command to set the encapsulation type and then the command: interface ethernet 0.2

This command would also need to be followed by its encapsulation type.

Incorrect Answers:

A, C and D are incorrect; for a subinterface to be numbered the interface needs to be indicated. Therefore the command would need to 0.x. x could be any number between the range of 1 to 4294967293.
