INTRO tomorrow

Last minute question as I do my studying.

I'm using the kaplan self test software and noticed that when a question asks for useable subnets it marks answers wrong that make use of the first and last subnet. I was under the impression that ip-subnet zero was assumed to be on, am I wrong in my assumption?

When I get a question, such as "you have an ip address 192.168.1.0 /24, list the first 2 available subnets?"

Should I answer 192.168.1.0 and 192.168.2.0 OR is it 192.168.2.0 and 192.168.3.0? Thanks for the last minute help.

Good luck...

Always assume that sub-net zero is turned off. Do not use the first and last subnet.

This is no longer the case on the CCNA exams, you should assume that ip subnet-zero is on and all subnets are useable. The official courseware uses 2**s to calculate the number of subnets (no longer2**s - 2) and of course it is still 2**h - 2 when calculating the number of hosts. Either way it will be obvious in the questions what they are looking for.

Thanks! I wish the self test software was kept up to date. I just ordered this 2 weeks ago, lol.

UPDATE: Passed w/ 916. Test wasn't nearly as hard as I thought it was going to be. Matter of fact my first sim got all screwy. When I was going back through to verify my config the text kept overlapping and deleting wouldn't work. I had the test proctor put my on another machine and she said if I failed they'd comp me a voucher (being that it took nearly 5 minutes to get me back up and running) b/c I was pressed for time as it was. I was on number 7 of 42 and only had 50 minutes left. I was really prepared b/c after the sim got worked out I finished the test w/ 15 minutes remaining.

Congratulations!

Don't worry, ICND will probably more than make up for it by being harder than you expect.

So study extra hard!

Haha, just what I like to here. Hope to take ICND before the end of August when I start classes again.

Congrads -

Sorry I steered you wrong on the subnet zero question. Fortunately, I got no questions on the Intro exam where it mattered.

I've just begun studying for ICND after passing Intro July 23. I find ACL's and Spanning-Tree difficult, but it will eventually sink in.

CONGRATULATIONS ON THE PASS

Good going! I must admit, I'm jealous with your score, as I've failed the INTRO twice now. Best I got was 800. Considering how well you did, I'm sure you'll do well on the ICND, too.

Well in mate... good luck with the ICND!
