What is a valid example of a vSphere Update Manager upgrade?
A. A VMware Tools upgrade on a Fault Tolerant machine with automatic snapshots.
B. Upgrading and patching multiple ESXi hosts simultaneously in a selected cluster.
C. Upgrading an ESX 4.1 host to ESXi 5.x with a sufficient boot partition.
D. An ESXi 5.x host update with automatically deleted snapshots.
Correct Answer: C
Explanation/Reference:
ESX 4.1 hosts sometimes do not have sufficient free space in the /boot partition to support the Update Manager upgrade process. Hosts must have more than 350MB of free space in the /boot partition to support the Update Manager upgrade process.
If the host that you are upgrading does not have more than 350MB of free space in the /boot partition, use a scripted or interactive upgrade instead.
