12. which command listed below enables load balancing over two multiple paths for ipx on a CISCO router? a.) ipx routing 2 b.) ipx round-robin 2 c.) ipx maximum-paths 2 d.) ipx rip 2 e.) ipx sap 2 f.) ipx gns 2
c the default ipx routing protocol is ipx-rip. by default, rip selects the best path, and keeps only one route in its routing table. the ’ipx maximum-paths’ command allows rip to load balance over up to 6 paths.
13. which of the following is an example of the physical layer? a.) ip b.) llc c.) sql d.) ddp e.) ethernet
e
14. what class address is 193.1.3.4 ? a.) c b.) b c.) multi-cast d.) broadcast e.) a f.) d
a
15. novell netware has an ethernet frame type called ethernet_802.3. what is the matching cisco command line keyword for this encapsulation method? a.) arpa b.) snap c.) novell-ether d.) sap e.) dix f.) gns
c novell 802.2 = sap (contains 802.2 llc headers) novell 802.3 = novell-ether (netware proprietary) ethernet_ii = arpa (the internet standard) snap = snap (field type set to ’aa’)
16. what would be the first command from global configuration mode to perform the following: 1. enable igrp on the router for interface e0 2. tell igrp to use an address of 157.89.4.4 255.255.255.0 3. tell igrp to provide routing updates for as number 200? a.) router igrp 157.89.4.4 b.) network 157.89.4.0 255.255.255.1 c.) router igrp int e1 d.) router igrp 157.89.0.0 e.) network 157.89.4.0 f.) router igrp 200
f. you have to specify which routing protocol first. for igrp you must also specify the autonomous system number. router(config)#router igrp ?  autonomous system number
17. from global configuration mode, which command will create subinterface #1 for serial 0? a.) int sub serial 0 b.) int serial 0 subinterface 1 c.) int ss 0 d.) int s0.1 point-to-point e.) int serial 0 subinterface 0 f.) int s0
d. command syntax for creating sub-interfaces:
18. the command ’ip host dallas 157.89.8.64’ maps the host name dallas with its ip address. what command would display all such mappings? a.) show dns b.) show dns entry dallas c.) show neighbors d.) show hosts e.) show ip table f.) show dns cache
d router#show hosts host flags age type address(es) www.eku.edu (temp, ok) 0 ip 157.89.8.2 dallas (perm, ok) 0 ip 157.89.8.64 perm - permament static entries temp - temporary usually resolved via dns
19. the command ’show running-config’ displays the configuration script in ram, but what other command could you use to show information about objects stored in ram? a.) show startup-config b.) show all c.) show config d.) debug ram e.) show buffers f.) show start
e packets are stored in memory locations called buffers during periods when the router BEComes over-loaded with other requests.
20. which of the following are examples of the datalink layer? (2 answers) a.) sql b.) ip c.) mac d.) tcp e.) llc
c e mac and llc are the sublayers of the datalink layer.
21. which type of switching reads in the entire frame before forwarding it? a.) fast forward b.) tabling c.) cut-through d.) store-and-forward e.) inverse arp f.) routing
d store-and-forward is slower, but it checks the frame for errors before forwarding. this can actually help to improve overall network performance on noisy lines.
22. what is the standard isdn term for a non-native analog telephone? a.) et b.) le c.) te2 d.) te1 e.) ta c terminal equipment 2 (te2) does not support native digital isdn. the analog device will require an external analog to digital converter.
