NetApp Certified Data Administrator (NCDA) – E-Series — Question 50

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?

Answer options

• 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.

Correct answer: C

Explanation

The correct answer is C because if the MTU is not properly configured on the ESXi hosts to match the jumbo frames set on the data LIFs, it can lead to connectivity issues. Option A is incorrect as NFS v3 is indeed compatible with ESXi hosts. Option B is irrelevant to the mounting issue, and option D is wrong since the export policy was set to allow all hosts.
