During an upgrade, the ESXi 5.x installer finds an existing version of ESXi and a VMFS3 volume.
No virtual machines exist on the host or VMFS3 volume. The requirement is to upgrade to
VMFS5.
Which option should be chosen to meet this requirement?
A.
Upgrade ESXi and preserve the VMFS datastore
B.
Install ESXi and preserve the VMFS datastore
C.
Install ESXi and overwrite the VMFS datastore
D.
Upgrade ESXi and overwrite the VMFS datastore
Explanation:
C is correct
When an existing ESX/ESXi 4.x installation is detected, the ESXi Installer will prompt to both migrate (upgrade) the host and preserve the existing VMFS datastore, or to do a fresh install (with options to preserve or overwrite the VMFS datastore). As there is no vm exists so Install ESXi and overwrite the VMFS datastore

During an interactive upgrade, the only options you have are:
-Upgrade ESXi, preserve VMFS datastore
-Install ESXi, preserve VMFS datastore
-Install ESXi, overwrite VMFS datastore
Since the question states that “The requirement is to upgrade to VMFS5.” and there are no other VMs on the datastore, the only single step option you have is “C. Install ESXi and overwrite the VMFS datastore”
In the real world you would most likely choose the option to upgrade so you don’t lose your configuration, and then delete the datastore and recreate it as VMFS5, but that answer is not given to us as an option.

■
Install ESXi, preserve VMFS datastore
