An administrator has just completed an upgrade of an ESXi 5.x host. Prior to the upgrade, a backup of the host configuration was performed. After the upgrade, the backup was restored to the upgraded host. Shortly after the upgrade was completed, the administrator receives complaints that users are unable to power on virtual machines.
What are the two most likely reasons that VMs cannot power up on this host? (Choose two.)
The ESXi host had a corrupt installation that was never properly repaired before the backup was taken.
The backup applied to the host after the upgrade was taken before the host was licensed.
The backup applied to the host after the upgrade corrupted the image.
The host was not licensed after the upgrade.
