An administrator is upgrading an ESXi 3.5 host to ESXi 5.x with an intermediate upgrade to 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.
The ESXi host has 4GB RAM.
B.
The ESXi host has one processor.
C.
ESXi 3.5 is not supported for upgrade.
D.
Update Manager cannot upgrade a previously upgraded host.
I’d argue (B)
ESXi 5.0 requires a host machine with at least two cores. The question doesn’t specify multi-core, so you can assume a single logical proc.
You can use update manager to upgrade a previosly upgraded host. Version of update manager must match the version your are trying to go through. ESXi 3.5 partition layout may also not be compatible with ESXi 5.
I believe Intel Xeon’s are Dual Core processors, so perhaps it assumes you know that, making D the only other possible answer.
