Networking Interview Questions
- As system administrator, you type “debug ipx sap” and receive the following lines as part of the IOS response: type 0×4, “HELLO2″, 199.0002.0003.0006 (451), 2 hops type 0×4, “HELLO1″, 199.0002.0003.0008 (451), 2 hops What does “0×4″ signify?
* That is a Get Nearest Server response.
* That it is a General query.
* That it is a General response.
* That it is a Get Nearest Server request.
Correct answer: A
- To monitor IP igrp traffic, you can use “debug IP igrp transaction” or “debug IP igrp events”. How do you display information about IPX routing update packets?
* debug routing
* debug ipx transaction
* debug ipx routing activity
* debug ipx events
Correct answer: C
- To monitor ipx traffic on a network, what command would you use?
* debug ipx transaction
* show ipx traffic
* show ipx events
* display ipx traffic
Correct answer: B
- What command would you use to find out the names of Novell servers on a network?
* show ipx servers
* show ipx hosts
* show ipx sap
* show ipx nodes.
Correct answer: A
- The “ipx delay number” command will allow an administrator to change the default settings. What are the default settings?
* For LAN interfaces, one tick; for WAN interfaces, six ticks
* For LAN interfaces, six ticks; for WAN interfaces, one tick
* For LAN interfaces, zero ticks; for WAN interfaces, five ticks
* For LAN interfaces, five ticks; for WAN interfaces, zero Ticks
Correct answer: A
The default is–for LAN interfaces, one tick; for WAN interfaces, six ticks
- 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?
* interface ethernet 0.1 ipx encapsulation Novell-ether ipx network 9e interface ethernet 0.2 ipx network 6c
* interface ethernet 0 ipx encapsulation Novell-ether ipx network 9e interface ethernet 0 ipx encapsulation sap ipx network 6c
* interface ethernet 0.1 ipx encapsulation Novell-ether interface ethernet 0.2 ipx encapsulation sap
* interface ethernet 0.1ipx encapsulation Novell-ether ipx network 9e interface ethernet 0.2 ipx encapsulation sap ipx network 6c
Correct answer: 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
- What does the “IPX maximum-paths 2″ command accomplish?
* It enables load sharing on 2 paths if the paths are equal metric paths.
* It sets up routing to go to network 2.
* It is the default for Cisco IPX load sharing.
* It enables load sharing on 2 paths if the paths are unequal metric paths.
Correct answer: 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.
- You want to enable both arpa and snap encapsulation on one router interface. How do you do this?
* The interface can handle multiple encapsulation types with no extra configuration.
* Assign two network numbers, one for each encapsulation type.
* Enable Novell-ether to run multiple encapsulation types.
* Both arpa and snap are enabled by default so you don’t have to configure anything.
Correct answer: 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.
* False
* True
Correct answer: 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.
- To prevent Service Advertisements (SAPs) from flooding a network, Cisco routers do not forward them. How are services advertised to other networks?
* Each router builds its own SAP table and forwards that every 60 seconds.
* Each router assigns a service number and broadcasts that.
* SAPs aren’t necessary with Cisco routers.
* Cisco routers filter out all SAPs.
Correct answer: 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.
- Novell’s implementation of RIP updates routing tables every ____ seconds.
* 60
* 90
* 10
* 30
Correct answer: 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.
