Congrats dude !! you earn it
I'm going to my exam in March-10, i have my own home lab with worktation 8 , and i am trying as much as i can as you have recommended. my lab is full with two esxi and vCenter and VDR, vMA, Power CLI, shared Windows target SCSI, windows and Fedora VM's inside the esxi. my labtop is smoking but it is working, till now at least 
PLUS I have printed out all the guides for vSphere 5, overview - installation- upgrade, managment , network, storage, security, HA, Resource, troubleshooting, scenariosetc.. , and around 5 guides for CLI,,
total of 20 guide, around 2000 pages, am reading from them and look every thing i read in the lab,
Do you think that this will be enough? i did not look at any other books that you have mention in your blog, - i wish to do but after the exam - , i ma using only the guides? do you recommend ;me to keep going with this?
do you have further recommendation for me?
What about the CLI commands?? am really weak at this point?? is there a lot of question about it?? i can complete the normal guides but am afraid i can go through all the CLI guides due to time issue
Thanks in advance
