2) constrate on your dod model. what is tcp, udp and how they perform their functions.
3) know your cisco commands. for example, how to enable banners. you will see a a section of banner's in todd's book.
router(config#) banner motd #. you will be confused by saying that you must use this command in order to logon to the router which is wrong.
choose the answer which hit enter and you will see a banner.
what are the three ways to modify your running-configuration file.
what are the three ways to display ipx interface e0. they are: sh ipx interface e 0, sh ipx int e0, and sh ipx interface ethernet 0.
4) define access-list commands. you will be confused by seeing that
* router(config-if) access-list 1 permit 172.16.20.1 0.0.0.0
you see a catch here. you define this command at global level, not interface level.
you would define ip access-group 110 in at interface level. keep this in mind where to define which command.
how to define a range of access list: for example, 172.16.10.0 - 172.16.40.0. what is the wild mask you will use.
study complex subnetting throughly. meaning if you cross 8-bit boundry. for example: take an ip address 172.16.0.0. it is a class-b network. you use 11-bit for subnetting. you will be asked to choose the correct range of host addresses. todd has shown the chart which will help you a lot.
what's the default subnet mask for class a, b and c.
on wan: study isdn and frame relay. constrate more on isdn. i only saw one question about frame relay which is (router-sub-if)# interface 0.1 point-to-point. catch is you must define point-to-point or multipoint in order to complete the command.
isdn: i had 4 questions. study reference points and protocols.
for example e.i.q.
e defines and existing line. i defines concept and terminology and q defines switching. question would be mixed. just align them. other questions are
isdn provides data only, wrong
isdn provides voice only, wrong
isdn provides both data and voice correct
isdn provides more bandwidth than fraction 56k t-1 line. correct
