An administrator is updating a program running on a virtual machine. The update file has been downloaded as an .iso file and placed on a shared NFS datastore. An attempt to mount the .iso file to the virtual machine fails, but subsequent testing shows that the .iso file can be mounted to a virtual machine running on another ESXi host.
Which step can be taken to enable access to the .iso file for the affected virtual machine?
Reboot the ESXi host running the affected virtual machine.
Remount the NFS volume to the ESXi host running the affected virtual machine.
Rescan all datastores.
Reboot the NFS server.
