4.0 using Update Manager. The host has a single Intel Xeon processor, 4GB of RAM, and a
VMFS datastore on a private, SAN-attached LUN. What might cause the upgrade to be
unsuccessful?
A.
Update Manager cannot upgrade a previously upgraded host.
B.
The ESXi host has 4GB RAM.
C.
The ESXi host has one processor.
D.
ESXi 3.5 is not supported for upgrade.

D is correct :
Hostupgrades are only supported from ESX4.0 hosts onward.
This is due to the /boot partition being too small on ESX3.5 hosts (or ESX4 upgraded from ESX3 hosts).
