Answer: c
Explanation: Ethernet 802.3 is used with NetWare versions 2 through 3.11, Ethernet 802.2 is used withNetWare 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.
You are a system administrator on a NetWare network, you are runningNetWare 4.11 and you cannot communicate with your router. What is the likelyproblem?
Answer: a
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. Whichstatements are true?
Answer: a, c & d
Explanation: The network address can be up to 16 hexadecimal digits in length. The node number is 12hexadecimal digits. The node address is usually the MAC address. An example IPXaddress is 4a1d.0000.0c56.de33. The network part is 4a1d. The node part is0000.0c56.de33. The network number is assigned by the system administrator of theNovell network.
Which NetWare protocol works on layer 3–network layer—of the OSI model?
Answer: a
Explanation: IPX (Internetwork Packet Exchange) is a NetWare network layer 3 protocol used fortransferring information on LANs.
Answer: a
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 routingprotocol.
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 commandthat you should use?
Answer: d
Explanation: The “debug IP IGRP events” is used to only display a summary of IGRP routing information. You can append an IP address onto either command to see only the IGRP
updates from a neighbor.
What does the following series of commands accomplish? RouterIGRP 71 network10.0.0.0 router IGRP 109 network 172.68.7.0
Answer: a
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 thedefault settings. What are the default settings?
Answer: a
Explanation: 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 Ciscorouter to allow for both sap and Novell-ether encapsulations. Which set ofcommands will accomplish this?
Answer: d
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 encapsulation sap IPX network 6c.
Answer: a
Explanation: It enables load sharing on 2 paths if the paths are equal metric paths. The default is 1 pathand the maximum is 512 paths.
You want to enable both arpa and snap encapsulation on one router interface.How do you do this?
Answer: b
Explanation: To assign multiple network numbers, you usually use sub interfaces. A sample configuration follows: IPXEthernet 0.1 IPX encapsulation novell-ether ipx network 9e interface ethernet 0.2 ipx encapsulation sap ipx network 6c
Answer: a
Explanation: 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 theGNS SAP.
To prevent Service Advertisements (SAPs) from flooding a network, Cisco routersdo not forward them. How are services advertised to other networks?
Answer: a
Explanation: Cisco routers build SAP tables and forward the table every 60 seconds. All SAPs can’t befiltered even with 4.x since NDS and time synchronization uses SAPs.
Novell’s implementation of RIP updates routing tables every _________ seconds.
Answer: a
Explanation: 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.
In Novell’s use of RIP, there are two metrics used to make routing decisions.Select the two metrics.
Answer: a& b
Explanation: It first uses ticks (which is about 1/18 sec.); if there is a tie, it uses hops; if hops are equal,then it uses an administratively assigned tiebreaker.
