Question 1.
Which of the following commands enables native IPX routing on a Cisco router?

a) ipx routing enable
b) enable ipx routing
c) enable ipx
d) ipx routing

Answer
d) ipx routing

Explanation
To enable routing of IPX/SPX traffic on a Cisco router, you do two things. The first is to enter the global command ipx routing, then you assign an IPX network number on each router interface that will connect to an IPX network segment.

Be aware that NetWare 5.x and beyond runs natively over IP, preserving the higher-layer NetWare services but not using IPX routing except in legacy parts of the network.

Question 2.
The following command appears in the configuration file of a router:

ipx routing 2198.7624.8b45

What is the significance of the number 2198.7624.8b45?

a) It is the autonomous system number assigned to the IPX routing process.
b) It is the process ID used by the router for IPX communications.
c) It is the MAC address of the first Ethernet interface in the router.
d) It is network address to be used for all LAN interfaces that will support IPX communications.

Answer
c) It is the MAC address of the first Ethernet interface in the router.

Explanation
IPX addresses are composed of two sections. A 32-bit network number and a 48-bit node address. In hexadecimal, these are written respectively as an 8-character network number, and a 12-character node address. This node address is generally the MAC address of the network adapter. But, since WAN interfaces (such as serial adapters) do not have MAC addresses, the router assigns the address of the first LAN interface that is active at the time IPX initializes to the IPX routing process and uses it for WAN interfaces. If you enable IPX routing with the global command ipx routing, the router selects the MAC address of the first Ethernet interface and adds it as part of the command in the configuration file.

Question 3.
Which of the following is a valid IPX host address?

a) 2.0000.45ba.758f
b) 56-32-45-7a-56-9f
c) 8454.6743.1866
d) 84.5654.3453

Answer
a) 2.0000.45ba.758f

Explanation
An IPX network address is composed of a 1- to 8-character network address and the 12-character MAC address of the device. The network and node portions of the address are separated by a period, and the node is generally divided into three groups of four characters each separated by a period. This makes 2.0000.45ba.758f the only valid address. All of the remaining choices could be MAC addresses only.
