Which type of Ethernet framing is used for TCP/IP and DEC net?

A. Ethernet 802.3
B. Ethernet 802.2
C. Ethernet ii
D. Ethernet snap

Explanation: The Ethernet 802.3 framing is used for NetWare versions 2 to 3.11, and the Ethernet 802.2 framing is used for NetWare versions 3.12 and later plus OSI routing, Ethernet II is used with TCP/IP and DEC net, and Ethernet SNAP is used with TCP/IP and AppleTalk. The type field in Ethernet 802.2 frame is replaced by a length field in Ethernet 802.3.

Consider a situation in which you are a system administrator on a NetWare network, you are running NetWare 4.11 and you cannot communicate with your router. What is the likely problem?

A. Netware 4.11 defaults to 802.2 encapsulation
B. Netware 4.11 defaults to 802.3 encapsulation
C. Cisco routers only work with netware 3.11
D. Netware 3.11 defaults to 802.2 encapsulation

Explanation: The default encapsulation on Cisco routers is Novell Ethernet_802.3 and NetWare 3.12and later defaults to 802.2 encapsulation, 3.11 and earlier defaults to 802.3.

NetWare IPX addressing uses a network number and a node number. Which statement is not true?

A. The network address is administratively assigned and can be up to 16 hexadecimal digits long
B. The node address is always administratively assigned
C. The node address is usually the mac address
D. If the mac address is used as the node address, then ipx eliminates the use of arp

Explanation: The network address can be up to 16 hexadecimal digits in length. The node number is 12 hexadecimal digits. The node address is usually the MAC address. An example IPX address is 4a1d.0000.0c56.de33. The network part is 4a1d. The node part is 0000.0c56.de33. The network number is assigned by the system administrator of the Novell network and the MAC address/node address is not assigned by the administrator.

Which NetWare protocol works on layer 3–network layer—of the OSI model?

A. Ipx
B. Ncp
C. Spx
D. Netbios

Explanation: IPX (Internetwork Packet Exchange) is the NetWare network layer 3 protocol used for transferring information on LANs that use Novell’s NetWare.

Which NetWare protocol provides link-state routing?

A. Nlsp
B. Rip
C. Sap
D. Ncp

Explanation: NetWare Link Services Protocol (NLSP) provides link-state routing. SAP (Service Advertisement Protocol) advertises network services. NCP (NetWare Core Protocol) provides client-to-server connections and applications. RIP is a distance vector routing protocol. NLSP was developed by Novell to replace RIP routing protocols.

As a system administrator, you want to debug IGRP but are worried that the “debug IP IGRP transaction” command will flood the console. What is the command that you should use?

A. Debug ip igrp event
B. Debug ip igrp-events
C. Debug ip igrp summary
D. Debug ip igrp events

Explanation: The “debug IP IGRP events” is used to display a short summary of IGRP routing information. You can append an IP address onto either console’s command-line to see only the IGRP updates from a neighbor. The command will only give a short summary and hence won’t flood the command line.

What does the following series of commands “Router IGRP 71 network” accomplish? 10.0.0.0 router IGRP 109 network 172.68.7.0

A. It isolates networks 10.0.0.0 and 172.68.7.0
B. It loads igrp for networks 109 and 71
C. It disables rip
D. It disables all routing protocols

Explanation: It isolates network 10.0.0.0 and 172.68.7.0 and associates autonomous systems 109 and71 with IGRP. IGRP does not disable RIP, both can be used at the same time.

The “IPX delay number” command will allow an administrator to change the default settings. What are the default settings?

A. For LAN interfaces, one tick; for WAN interfaces, six ticks
B. For LAN interfaces, six ticks; for WAN interfaces, one tick
C. For LAN interfaces, zero ticks; for WAN interfaces, five ticks
D. For LAN interfaces, five ticks; for WAN interfaces, zero ticks

Explanation: Tick is basically the update rate of clients in the network. The IPX delay number will give the ticks at a certain time. The default ticks are–for LAN interfaces, one tick, and 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?

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

Explanation: The following commands setup the sub interfaces to allow for two types of encapsulation:interface Ethernet 0.1 IPX encapsulation Novell-ether IPX network 9e interface Ethernet0.2 IPX encapsul

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

Explanation: 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. The value must always be greater than 1 and must be a natural number.
