Part - 3 CCNA Interview questions and answers

11 As a system administrator, you need to set up one Ethernet interface on the Cisco router to allow for both sap and Novell-ether encapsulations. Which set of commands will accomplish this?

• A. interface ethernet 0.1 ipx encapsulation Novell-ether ipx network 9e interface ethernet 0.2 ipx network 6c

• B. interface ethernet 0 ipx encapsulation Novell-ether ipx network 9e interface ethernet 0 ipx encapsulation sap ipx network 6c

• C. interface ethernet 0.1 ipx encapsulation Novell-ether interface ethernet 0.2 ipx encapsulation sap

• D. interface ethernet 0.1ipx encapsulation Novell-ether ipx network 9e interface ethernet 0.2 ipx encapsulation sap ipx network 6c

Ans D

The following commands setup the subinterfaces to allow for two types of encapsulation: interface ethernet 0.1 ipx encapsulation Novell-ether ipx network 9e interface ethernet 0.2 ipx encapsulation sap ipx network 6c

12 What does the "IPX maximum-paths 2" command accomplish?

• A. It enables load sharing on 2 paths if the paths are equal metric paths.

• B. It sets up routing to go to network 2.

• C. It is the default for Cisco IPX load sharing.

• D. It enables load sharing on 2 paths if the paths are unequal metric paths.

Ans A

It enables load sharing on 2 paths if the paths are equal metric paths. The default is 1 path and the maximum is 512 paths.

13 You want to enable both arpa and snap encapsulation on one router interface. How do you do this?

• A. The interface can handle multiple encapsulation types with no extra configuration.

• B. Assign two network numbers, one for each encapsulation type.

• C. Enable Novell-ether to run multiple encapsulation types.

• D. Both arpa and snap are enabled by default so you don't have to configure anything.

Ans B

To assign multiple network numbers, you usually use subinterfaces. A sample configuration follows: ipx ethernet 0.1 ipx encapsulation novell-ether ipx network 9e interface ethernet 0.2 ipx encapsulation sap ipx network 6c By default, Cisco routers forward GNS SAPs to remote networks.

• A. False
• B. True

Ans A

GNS is Novell's protocol to Get Nearest Server. If there is a server on the local network, that server will respond. If there isn't, the Cisco router has to be configured to forward the GNS SAP.

14 To prevent Service Advertisements (SAPs) from flooding a network, Cisco routers do not forward them. How are services advertised to other networks?

• A. Each router builds its own SAP table and forwards that every 60 seconds.

• B. Each router assigns a service number and broadcasts that.

• C. SAPs aren't necessary with Cisco routers.

• D. Cisco routers filter out all SAPs.

Ans: A

Cisco routers build SAP tables and forward the table every 60 seconds. All SAPs can't be filtered even with 4.x since NDS and time synchronization uses SAPs.

15 Novell's implementation of RIP updates routing tables every ____ seconds.

• A. 60

• B. 90

• C. 10

• D. 30

Ans A

Novell's RIP updates routing tables every 60 seconds, Apple's RTMP is every 10 seconds, routers ARP every 60 seconds, IGRP signal every 90 seconds, and Banyan VINES signals every 90 seconds.
