Has anyone done QOS 642-642 recently?
I failed this one today.

I read the Cisco press Imp QOS (Exam guide) rev2 book cover to cover and was getting 100% on the enclosed boson.

However the exam was very different.

It even had 2 questions on QOS propagation over BGP which wasn't even mentioned in the book! These accounted for 5% of the score!

The terminology and context of many questions was different to the text and seemed almost designed to confuse; especially with the select 3 type questions.

Any ideas of how to properly prepare for these exams - is there an easy way to identify and gather material from the CCO?

Luckily Cisco are doing the fail once take again free promotion so I can retake this for free - however I want to make sure my week spent studying is not wasted.
This exam 642-642 has been around a while - I wonder if it has changed significantly?

Oh dear, sorry to hear that you fail the test..

Hmmm.. doesnt fill me with confidence for my test tomorrow as I have been studying from the same 2nd Edition Cisco Qos book.. This book is coming up to 3 years old... however, there doesnt seem to be any other material out there of use worth looking at..

Ive heard murmurings of BGP coming up in the exams as well.. so will make sure that I have a quick read up on that is there is no mention of it in the Cisco book.. or the Cisco official blueprint.. !!

There was also some debate about SRR queuing appearing and not WRR queue..

Best of luck with your retake... Just out of interest, this free retake exam from Cisco.. Was this a promotion you had to register for prior to the exam or did you find out afterwards.. ??

Unfortunately, the Boson stuff in the Cisco Press books aren't written by the Boson staff. Trying to get that changed...

Best advice I can give is to study the areas where you are weak, either in the book or on Cisco's site.

Best of luck on your next attempt!

Hey..

Just to say that I passed the QOS exam earlier this afternoon...

After thoughts.. Yeah, I can see what you mean about wording of the questions being slightly different.. I do like the fact that the multianswer questions specify how many answers you have to put down rather than the horrible "choose all that apply "...
Had to read alot of them very carefully and used the process elimination for some..

Thanks for the heads up on the BGP.. did a quick (panic) bit of reading on that last night.. apart from that I would say that the blueprint is accurate and I found that the Cisco Study guide covered all the concepts required to pass the exam..

Best of luck...

Thanks!

Yeah!
I had a (relatively) alcohol free week, stuck my head in Boson and the CCO and passed my QOS exam today, a week later! Phew!

I'm glad you passed yours! I don't think cisco are doing the 'Comeback' promotion in the States. I'm glad I didn't have to pay for my retake.

Maybe I was just unlucky but I knew TOS/DSCP back to front and there were no questions at all on binary AF or IP-Prec - Doh!

Ah! Well! Onwards and upwards! I'm off to do CVOICE 642-432!

BTY - I wouldn't want to put anyone off buying the Cisco Press book.

(Apart from the fact it's the only game in town) It is well written, I found very few mistakes and it is a very good resource for this exam.

Unlike many course texts it is also a very good reference resource and I imagine I will use it a lot in the future.

Just make sure you swat up on QPPB, CAR and CEF/FIB before the test and use a recent exam sim (like boson) and don't rely on the one with the book!

Hey, well done to you too.. I applied the same tactics and then made up for the lack of alcohol in the system this last week.. Well earned holiday..

I second your comments regarding the Cisco books.. I found it very useful, plus they do provide the Cisco answer to questions....

Off to do the CVoice as well now.. Would prefer to do the newer exam but there is not enough material out at present..
