An administrator created an SVM for a VMware vSphere 6.5 cluster. For the SVM, the NFS protocol was enabled. Data LIFs were configured with jumbo frames. The nfs01 volume was created and mounted as junction path / nfs01. A VMware export policy that allowed all the hosts of the cluster was applied to the SVM. However, the hosts are unable to mount the volume. In this scenario, what caused the problem?
A. NFS v3 is not compatible with ESXi hosts.
B. The volume is not thin provisioned.
C. The maximum transmission unit (MTU) was not set properly on the ESXi hosts.
D. The default export policy needs to allow reads from the ESXi hosts.
Not sure, but seams that correct is D.

You must add a rule to the default export policy to enable ESXi host access through NFSv3. Without such a rule, all NFS clients are denied access to the storage virtual machine (SVM) and its volumes.
