What are three recommended prerequisites before upgrading virtual machine hardware? (Choose three.)
A. Create a backup or snapshot of the virtual machine.
B. Upgrade VMware Tools to the latest version.
C. Verify that the virtual machine is stored on VMFS3, VMFS5, or NFS datastores.
D. Detach all CD-ROM/ISO images from the virtual machines.
E. Set the Advanced Parameter virtualHW.version = 11
Before you upgrade the virtual hardware:
– Create a backup or snapshot of the virtual machine.
– Upgrade VMware Tools. On Microsoft Windows virtual machines, if you upgrade the virtual hardware before you upgrade VMware Tools, the virtual machine might lose its network settings.
– Verify that all .vmdk files are available to the ESXi/ESX hosts on a VMFS 3, VMFS 5, or NFS datastore.
– Verify that the virtual machines are stored on VMFS 3, VMFS 5 or NFS datastores.

Its from ESXi 5.1, but since the KB mentioned by Anonymous mentions “no inaccessible virtual disks, CD-ROM or ISO images”, I would not chose D as an option
