Took the 801 yesterday

Unanswered Question
Sep 20th, 2007

My second attempt at the 640-801. Passing was 849. I made 847. To say the air went out of me when I saw that would be an understatement. I'm *still* binging to get over it.

I have this problem too.

Don't give up. I know the feeling, but you'll nail it on your next try. Good luck

Just keep at it - with a score that close, just brushing up on your weak subjects should put you over the top.

just concerntrate on your weak are almost there.

I scored 831 on my THIRD attempt, so please don't give up.

I finally passed it yesterday. You'll get there.

A score of 849 to pass sounds very high. What is that out of, 1000?

rileymartin Sun, 09/23/2007 - 13:28

I read the exam is 90 minutes long and there are anywhere from 55-65 questions. That gives you less than 1.5 minutes per question. I'm sure some of the multiple choice questions can be answered quickly but I read there are testlets which are multiple questions in one and then of course there's subnetting which takes some time as well as the simulations. 90 minutes doesn't sound like enough time.

I had 53 questions in 90 minutes. I probably spent 8-12 minutes on the two simulations...leaving me not a lot of time for the others. Quite a few questions were rather straightforward and simply needed a correct answer without subnetting or anything. These only took a few seconds. That's how it's balanced. Some are really quick, others kind of long.

I finished with about 4 minutes remaning though.

Bottom line, be prepared to subnet very quickly, even in your head to some extent, if possible.

Correction: Eight to 12 minutes EACH on the two simulations...

I might have a solotion for you in finding more time during your exam.

Subnetting should cost you 10 sec a question there are some 10 questions about subnetting so that would not cost you more then 2 minutes. Subnetting in 10 seconds?

Yes its simple.

Write down the bitnumbers of the last 2 octets and the sequence of 128 64 etc.




for example give me the subnet and broadcastadress of

it's simple look at the table 22 is step 4

Divide 61 by step 4 and multiply the WHOLE NUMBER 15 by step 4 the subnet is 60 next subnet is 60 plus step 4 = 64 so broadcastadress is 63.255 (B-class)

61/4=15*4=60 next subnet 64 so subnet is 63.255

or look at the table. 19 is step 32

61/32=1*32 subnet= 32 next subnet is 32+32=64 so broadcast is 63.255

or /28

15/16=0 0*16=0 so subnet is 0 next subnet is 16 broadcast is 15 (C- class)


keesjan.schilstra Wed, 09/26/2007 - 23:15

Yes it does, look at the table if you have a /19 subnet then the step is 32 so you get a subnet starting at next etc..

Last calculation for the C class.

or /28

15/16=0 0*16=0 so subnet is 0 next subnet is 16 broadcast is 15 (C- class)

look at the table if you have a /28 subnet then the step is 16 so you get a subnet starting at next etc..

15 diveded by 16 is not possible so the answer is 0 so the subnet is 0 next subnet is 16 so last ip adress before the next subnet (16) is 15.

I took the 640-801 exam yesterday and failed with a score of 834.





I think my mistake was in the 2 simulations. The first simulation was had 5 sub-questions, so I answered the first one then when I click "NEXT" it took me out of the simulation and to another question. I think Cisco should design this better. The test taker interaction with this type of Simulation with multiple questions should be clear. I just didn't see the other 4 sub-questions in the simulation. Please let me know if anyone has seeing this and if they know what to do.

Now, the second simulation this one was my mistake. I created an ACL to block traffic to a Web Server from only one host but it didn't work so I moved on.

I like to ask the Cisco Tutor/any expert, what do you think if this time I take the 640-802 before Friday (I don't want to wait until Monday to retake the 640-801). Please advice; if not, what about me taking the INTRO & ICND instead (640-821 & 811)?



ascoolasice Thu, 09/27/2007 - 12:52

If I were you, I'll take the exam as soon as I can, maybe brush up on ACL, since you know what to expect. You're so close to passing the composite that the 2-exam route will be a waste of time and money. Just my opinion. Good luck.
