Explanation:
A. B. and E.

a. backup the host config using vicfg-cfgbackup command (yes we would like to backup in case we need to revert )
b. save custom scripts (Yes same as above)
c. backup all .vmx files (Why ? They are on VMFS Datastores which will not be touched during upgrade)

  1. JustAnotherVCPGuy says:

    Answer A: vicfg-backup is used to take a backup from ESXi servers, not ESX!

    Answer B: Valid, need them to revert the installation

    Answer C: Valid, however you should also backup .vmdk files etc.

    Answer D: Host profiles are to be created afterwards

    Answer E: Valid, you might need these upon restoring ESX4, or reuse them in ESXi v5

    So correct answer should be: BCE

      Just verifying that JustAnotherVCPGuy is correct on A being incorrect:

      http://pubs.vmware.com/vsphere-51/index.jsp?topic=%2Fcom.vmware.vcli.ref.doc%2Fvicfg-cfgbackup.html

      The vicfg-cfgbackup command backs up ESXi configuration data and restores them later. You can back up the host configuration, restore the configuration to the host, force the restore of the configuration, and reset the host to factory settings.

      Back up ESXi host configuration before you change the configuration or upgrade the ESXi image. The vSphere Upgrade Guide discusses backing up and restoring the ESXi configuration in some detail.

      Important: This command is supported for ESXi hosts but not for ESX hosts.
