An administrator sees the following error in the log files:
Which two events could be the source of the error message? (Choose two.)
A.
vCenter Server failure
B.
VXLAN failure
C.
Disk array failure
D.
Network failure
E.
ESXi host failure

And the battle rages on. See this link:

quite a few folks feel like the answer should be C and E. Do you have any references for why D is correct over E?

I agree with Adam, I think C and E are right because the fault can reside on the storage system or generated from the HBAs

If I had to go with an answer, I would probably choose C & E. Host failure is kind of vague, but to me.. That could mean any sort of hardware failure on the host.. such as HBA or NIC that is used to connect to the back-end storage array. A hardware failure on the host would indeed generate this kind of error.

I have had the exam today in Spain and, what a surprise, I’ve got a score of 500/500. Specifically in this question I’ve selected C & D: Disk Failure and Network Failure since it made little more sense for me.

I think we can all agree on C. If the storage subsystem fails, we can obviously no longer have access to the disk.
Between D and E…
I see the word SAN instead of NAS and I think of fibrechannel, but FCoE is also a SAN and uses a network. So that’s an argument for D.
Also, since the ESXi host reports this error (not vCenter), we can’t fail the entire host. But as @sparc states, it could be a partial failure of certain hardware. But would that report the hardware failure instead?
A quick Google finds this exact, and I mean EXACT (check the SID) error in VMware’s KB: https://kb.vmware.com/s/article/1009557
They refer to Fibre Channel as well.
I feel that a more compelling case can be made for D, using FC and FCoE.
So C & D.
