I'd like to share one tip which helped me - I had limited time to configure & play with all features in lab, so I watched technical videos on Youtube (mostly on VMware channels) - I think it was very useful for me as an addition to documentation.
I also recommend "Mastering vSphere" book - however I used version 5.0, not latest one.
Any other tips I am looking to write the exam this Thursday ... I have study the VCP 550 blueprint , taken the required class and gone through must of the YouTube tutorials as you suggested.
Just want to make sure that I am ready for whatever ... Thanks in advance for your help!
