If you are looking for practice questions for the CCNA here are a few I
wrote just now... some of them are probably deeply flawed, others probably
way beyond the CCNA level... still others probably have nothing to do with
I have the following /24 network:
I want to set up one subnet with 57 hosts on it, eight subnets with 2 hosts
and 10 subnets with 9 hosts on them.

The F/R Cloud including edge switches.

Are you a cat or a dog person?
Is $1600 too much to pay for a T1-WIC card?
NO, I own stock in Cisco.
The following command under 'line con 0', 'NO LOGIN' has what effect?
No one will be able to login.
No password is required, and people will automatically be put into enable
The following two commands are entered into a router:
Enable password cisco
Enable secret &341298HJKHSA3~!
Which password will be used to log you into enable mode?
no password will be required as the two commands cancel each other out.
If you have no internet connectivity when you first hook up your router,
whose fault is it, and who do you call first?
Your Telco, because everything is the telco's fault (if you have Verizon,
you are probably right (NOTE: I don't work for Verizon)).
Your IT person, because the router is probably misconfigured.
Who cares, it is supposed to work, so it should be working, you call
DLCIs matter? But I thought they were supposed to always be 16...
What do you mean I can't run an arc welder next to my SmartJack?
Seriously, it is always the telco's fault, because they are evil.
Which configuration prompt will you need to be in to apply an ACL the VTY

copy star tftp Copies running-config to
Which of the following commands is the same as 'copy running-config

A real quick note.
The Cisco certifications are driven by the Cisco TAC (Technical Assistance
Center)... when the managers at TAC see a massive influx of calls for a
specific issue, that issue goes right to the exams.
You want to know why you see so much ISDN on these tests? Because TAC gets a
crap-load of calls for ISDN (I used to think it was because Cisco got a
massive payment for every ISDN ckt sold...)
The CCIE lab is a little different, where Cisco instead is aiming their
sights at introducing new technologies... (which is why Dialer Watch was so
psychotically big last year on the lab)... But for the CCNP and CCNA exams,
the goal is to prevent as many TAC calls as possible... The thinking being
if the CCNAs can handle the minor grunt crap, TAC won't have to.
Hey, anyone else notice that TAC (not the initial screeners, but the guy who
calls you back) is not particularly well versed in the English language?
(I went from opening one TAC case a month to opening 30 a week... you would
be amazed at some of the bizarro error messages people get... and those
modemcaps are just bizarre to wade through)...
