So I took the CCIE lab and failed my first attempt. I realize now it’s more about efficiency and speed than skill. 8 hours goes by in what seems like an hour. So I decided what I needed to do was practice the lab by repetition. After creating a mock lab, I made snapshots in vmware, then created a Power CLI script and bat file to revert to the snapshot and power back on. In one click I can just start all over and do it again!
revert.ps1:
Connect-VIServer -Server vcenter -User root -Password blahblah
$VMs = Get-Content ‘C:\vmlist.txt’
Get-Snapshot -VM $VMs -Name ccie | Foreach-Object { Set-VM -VM $_.VM -Snapshot $_ -Confirm: $false }
Start-VM -VM $VMs
vmlist.txt:
HQ-PUB
HQ-SUB
SB-PUB
HQ-CUC
HQ-CCX
HQ-IMP
startover.bat:
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -PSConsoleFile “C:\Program Files (x86)\VMware\Infrastructure\vSphere PowerCLI\vim.psc1” -NoExit -Command “& ‘C:\revert.ps1′”
