files. In most routers, only an IOS is found. If microcode is upgraded, these files also
reside in Flash memory.

1
What are the two names for the router's mode of operation that, when accessed, enables
you to issue commands that could be disruptive to router operations?
Enable mode and privileged mode. Both modes are commonly used and found in Cisco
documentation.
2
What are three methods of logging on to a router?
Console, auxiliary port, and Telnet. All three cause the user to enter user EXEC mode.
3
What is the name of the user interface mode of operation used when you cannot issue
disruptive commands?
User EXEC mode.
4
Can the auxiliary port be used for anything besides remote modem user access to a
router? If so, what other purpose can it serve?
Yes: For direct attachment of a terminal, and dial for the purpose of routing packets.
Although originally created to support remote administration access, many customers use
an auxiliary port for dial backup, particularly when analog lines are desired or when that
is all that is available.
5
How many console ports can be installed on a Cisco 7500 router?
One. This is a purposefully strange question. You do not order the console port; every
router comes with one and only one. So, technically, you do not even order one because it
is implied by ordering the router.

What command would you use to receive command help if you knew that a
show
command
option begins with a
c,
but you cannot recall the option?
show c?
. Help would appear immediately after you typed the

symbol. You would not
need to press Enter after the
?
. If you did so, the router would try to execute the command
with only the parameters you had typed after the
?
.
