I have been studying really hard for this, with a personal goal to certify on the new vSphere line by years end. Today that came true, with God by my side. The exam, about 85 questions and 90 minutes to complete, I had about 10 minutes left. This was a much more reasonable # of questions than the 270 we had in the Beta exam.I have posted earlier links to the study material I used. The vreference cards and Simon Long (http://www.simonlong.co.uk/blog/vcp-vsphere-4-practice-exam/) practice exams I think were very helpful in giving me confidence.
Good luck to you all going for your VCP certification! I'm off the donate some $$$ to simonlong.

Three training courses now meet the requirement for VCP4
Fast Track is still the best option as troubleshooting assumes knowledge from the others.
New VMware Education Classes:
1-day Manage Scalability: covers the specific features of vSphere related to scalability, such as Host Profiles, Distributed Power Management, and vCenter Linked Mode
1-day Manage Scalability: covers the specific features of vSphere related to scalability, such as Host Profiles, Distributed Power Management, and vCenter Linked Mode
4-day Troubleshooting: Very intensive: you will spend most of the time diagnosing and rectifying configuration problems created on VMware® ESX™/ESXi hosts and VMware vCenter™ Server systems.

Awesome Daily ESX Farm report
Based on Powershell, this is a script I now schedule to run every morning so I have a nice report each day and I save the report in a folder.
http://www.virtu-al.net/2009/07/14/powercli-daily-report/
I donated $25 I thought it was so good. Very customizable by by easy commenting or uncommenting sections in the code.
I scheduled it in task scheduler with these commands:
C:\WINDOWS\system32\windowspowershell\v1.0\powershell.exe
in the arguments section: -PSConsoleFile "C:\Program Files\VMware\Infrastructure\VIToolkitForWindows\vim.psc1" & C:\Scripts\dailyreport.ps1 vcenter
vcenter would be the name of our virtual center server.

Vmotion Stats: how fast can we go
I came across this little tip from this link:
http://kennethvanditmarsch.wordpress.com/2009/11/09/vmotion-speed-how-fast-can-we-go/
Apparently vSphere 4 will show you stats of your Vmotion performance.
Just do: tail –f /var/log/vmkernel
Article also explores does having a lot of bandwidth really help! Good read!
File Lock tip...how to deal with these:
We had a problem with a template..not being able to turn it on...we would get a file locked error.
Not sure how someone accomplished this but they had used the template VMDK file in a deployed virtual machine. How did I find this out? Using the command shown below, which looks through all the virtual machine config files to find if any other machines were using the file. xpsp2basethin.vmdk was the file in use.
[root@esx3srv0301ph xpsp2base]# egrep -i xpsp2basethin.vmdk /vmfs/volumes/*/*/*.vmx
/vmfs/volumes/499f22e3-2239bc87-25f0-001a6459e0f8/vpcuniversity2/vpcuniversity2.vmx:scsi0:0.fileName = "/vmfs/volumes/499f2335-cd135fea-a4dd-001a6459e0f8/xpsp2base/xpsp2basethin.vmdk"
/vmfs/volumes/499f2335-cd135fea-a4dd-001a6459e0f8/xpsp2base/xpsp2base.vmx:scsi0:0.fileName = "xpsp2basethin.vmdk"
/vmfs/volumes/hdsvpc3a/vpcuniversity2/vpcuniversity2.vmx:scsi0:0.fileName = "/vmfs/volumes/499f2335-cd135fea-a4dd-001a6459e0f8/xpsp2base/xpsp2basethin.vmdk"
/vmfs/volumes/hdsvpc6a/xpsp2base/xpsp2base.vmx:scsi0:0.fileName = "xpsp2basethin.vmdk"

Sorry for being away so long
I really enjoy sharing the information I learn with all of you. And I really appreciate all the other bloggers out there passing on their knowledge and experience. It's all about giving back to the community and helping others find how important the virtualization technology is to their careers and companies.
Unfortunately, I have been extremely busy at work and studying for the VPC 4 exam. Nothing like an economic crisis to get virtual as the first choice for new servers! My work also put in new security software that blocks many blog sites while others it allows..which has really been a pain. Then I remembered I could post via email..so I am back online again.
Thanks for visiting my blog. Stay tuned..we have a lot of catching up to do!!
