43 which command will start the process for a cisco ios file image upgrade? a.) network b.) copy tftp flash c.) download flash d.) copy flash tftp e.) download b 44 which of the following would be displayed by the command ’show cdp neighbor detail’? (4 answers) a.) amount of flash memory available b.) the routers hostname. c.) one address per protocol. d.) the subnet mask, if ip is configured. e.) the hardware platform. f.) the incoming/outgoing port.  
4 K& b4 a& F1 E1 Lb c e f cdp shows a lot of the same info that ’show version’ does locally, but flash memory is not part of it. the ’detail’ keyword is optional, but even when used, ip subnet mask information is not displayed by cdp for ip interfaces.  
45 what is the access-list wild card mask to match the range 100.1.16.0 - 100.1.31.255 ? a.) 0.0.15.255 b.) 0.0.7.255 c.) 0.0.31.255 d.) 0.31.255.255 e.) 0.0.255.255  
( W0 g7 g' U5 m+ |, q7 j$ m9 Pa access-list wildcard masks are the inverse of subnet masks. shortcut: take the the broadcast and subtract from the network. 100.1.31.255 - 100.1.16.0 ---------------- 0.0.15.255
46 the cisco discovery protocol (cdp) periodically sends out a multicast packet (at layer 2). which command will alter the default interval of 60 seconds? a.) cdp 111 b.) cdp hold 111 c.) cdp timer 111 d.) cdp wait 111 e.) cdp interval 111

48 what does the parameter -- log -- do on an ipx access list? a.) logs the creation of the access list. b.) logs ipx access control list violations whenever a packet matches a particular access list entry. c.) ensures the ipx protocol places a log in the fireplace. d.) the log keyword is not a valid option. e.) read the log to figure out what traffic to deny.

49 after the command -- router rip -- what command would enable rip on the router for interface e0, with an address of 157.89.4.4 and mask of 255.255.255.0 ? a.) network 157.89.0.0 b.) router rip 157.89.4.0 c.) router rip int e0 d.) router rip 157.89.0.0 e.) router rip * f.) network 157.89.4.0 255.255.255.0  
a ripv1 cannot use subnet mask information. ripv1 can only use the classful network portion, which in this case is a class b. so for our example, rip can only enumerate the ’157.89’ part. all interfaces in that network will be processed.  
, H8 f3 C/ D# l/ |+ A, W50 which command will enable debugging for ipx rip updates? a.) debug ipx packets b.) debug ipx rip c.) debug ipx d.) debug rip e.) debug ipx routing activity

51 what is the correct command line syntax for configuring a port on a 7000 or 7500 series cisco router with a vip card? a.) port adapter/port b.) slot c.) slot/port-adapter/port d.) slot/port e.) you can’t put a vip card in a 7000 or 7500 router. f.) port  
% G# J/ ~2 M6 [# I3 U" R! yc the vip cards have a port adapter, so you must also specify them as well. the syntax for a vip card is: ’interface serial slot/port-adapter/port’, where: slot = the big linecard slot # in the 7500 chassis, port-adapter = the pa mini-card slot # inside the larger linecard slot, port = the interface port # on the pa mini-card. imagine a larger slot (the linecard slot of the chassis) that in turn has two additional smaller slots for mini-cards (the vip pa slots).  
52 which of the following describe smtp? (2 answers) a.) used for managing ip devices. b.) uses icmp c.) uses tcp. d.) used for downloading files to the router. e.) uses udp. f.) used for sending e-mail.
