by Samuel Mitchell, posted in VMware

The following notes will assist you to prepare for this objective:

  • You need to know the files that make up a VM and what they do
    • VMX, VMDK, VSWP, VMSD, VMSN, etc
  • You need to know their behaviour
    • What gets created if missing?
    • What is naming convention of files?
    • What is the snapshot naming behaviour?
    • Any differences between VMFS5 and VMFS6?
    • How do resources reservation affects files?
  • You should also be familiar with virtual disk types
  • Try in your home lab to create VMs with
    • Thin provisioned disk
    • Thick provisioned disk
    • Eager zero thick provisioned disk
    • Could you convert from one disk type to another? How exactly?
  • Get to a vSphere host command line and look at what gets created
    • Nothin like doing to lock this into your memory!
