Just want to give thanks to all of you, only 3 days left, Monday is the day.
Thanks to much to JoshuaAndrewsVM
And all the people that answered my silly questions
That lab is amaizing mate!, I build my own after that experience, in an i5 Quadcore, 8GB RAM and two SATA disks hp box (not more than 300$), if someone needs advise to create something similar just let me know, as creating DC, vCenter, Openfiler, and 2 ESXi 5.5 with that resources is not easy task. Also you need to power on vms with patience, power on one, wait, then second... and let 10 minutes to disk I/O become stabilized, obviously if you can go for SSD GO!
But creating the environment with that resources has been so helpful troubleshooting and tunning everything to work, like playing with java HEAP...it's possible (maybe someone that has take the exam can confirm) that the constrait of resources can simulate the speed issues at exam that a lot of pleople reports :-)
Also if someone needs any advise in what sources I used please let me know, but I'm not sure yet that they work...
I think tomorrow I'm going to rest when I arrive from work, tough week at work including SRM exercises... also tomorow working...
Sunday I will reread my custom blueprint (also in my way to exam, 3 hours by train) and lets see if I can rest because I´m taking train at 6:00 AM and exam is at 11:15 AM on Monday.
Any last minute advise will be appreciated, again Thanks to ALL
