A Veeam proxy server is configured as follows. No modifications are allowed to the transport mode.
When performing a restore of a thin-provisioned VMware virtual disk on an NFS data store using this proxy server, what transport mode will be used by default?
The transport mode that will be used by default for a restore of a thin-provisioned VMware virtual disk on an NFS datastore, given the provided proxy server configuration, is 'Virtual appliance'. This is because, when the automatic selection mode is enabled and assuming no specific mode has been disallowed, Veeam will prioritize the use of the virtual appliance mode (also known as HotAdd) for NFS datastores. This mode allows efficient data transfer without requiring additional network resources and is typically the preferred method for restoring thin-provisioned disks on such storage.
D is correct https://helpcenter.veeam.com/docs/backup/vsphere/direct_nfs_access_proxy.html?ver=120
Assuming that the proxy can access the NFS-share. Otherwise NBT or Hotadd are valid options
