An administrator has recently upgraded their Update Manager infrastructure to vSphere 5.x.
Several hosts and virtual machines have not been upgraded yet.
Which vSphere component when upgraded will have the least impact to the existing environment?
A.
Virtual Machine Hardware
B.
ESX Hosts
C.
VMFS datastores
D.
VMware Tools
I realize this is the right answer, but honestly I think it’s insane. I can vmotion servers off the host and upgrade it with no worries about downtime. However, upgrading the tools often requires a restart on that server. So this is a much greater impact to users than upgrading the host.
They mean impact to the environment overall over the long run. Upgrading a host has a big impact. Upgrading the datastores too. Updating the hardware version – somewhat. You get some extra functionality. Upgrading tools? Not so much. I can be a couple levels behind on tools (or not installed at all) and still function.
