Took the CCNA 607 exam today and passed with a 949.
Exam was pretty straightforward. I've spent the last 2 weeks studying 4-5 hours a day for this thing so it went about as well as I expected.
I used Lammele's Sybex book and the big Cisco Press CCNA book. I also used Boson's NetSim to study for the simulations.
I got 2 on my exam. A RIP one and one where you had a router with 2 unconfigured interfaces. They give you a subnet and tell you to use the 1st available IP in the 1st subnet for the E0 interface and the 1st available IP in the 2nd subnet for the S1 interface. Pretty straightforward...
Not much in the way of ISDN or IPX on my exam which I was glad to see as those are my 2 weakest areas for sure.
Lots of stuff on VLAN's, STP, and general switching though.
Only had one fill in the blank which was an easy subnetting question where I had to type in the mask.
Overall though, the test wasn't easy - but it's fair. There were a few 'tricky' questions but if you study well you will see a few familiar questions that you will be able answer quickly so you can spend more time on the ones that require that you map out subnets, etc...
Good luck to all those that are studying for this one.
Oh, at the beginning of my exam they said that they are alloting more time to take the test now. I got 90 minutes to answer 60 questions.
Be prepared to spend the first several minutes answering questions about what level you are on certain Cisco related technologies (beginner, intermeidate, advanced, etc...)
Not sure what it's worth - but I answered beginner on all of them.

Anyway - good luck everyone!
