Refer to the Exhibit. An administrator is adding an NFS datastore as shown in the Exhibit. What is the purpose of the Servers to be added list?
The correct answer is A. It contains the IP addresses of the NFS Storage Server to provide multipathing capability. The 'Servers to be added' list in the NFS datastore wizard accepts multiple NFS server IP addresses that all export the same share, enabling NFS multipathing for redundancy and throughput.

Why each option
The 'Servers to be added' list in the NFS datastore wizard accepts multiple NFS server IP addresses that all export the same share, enabling NFS multipathing for redundancy and throughput.
vSphere NFS multipathing works by specifying multiple IP addresses belonging to the NFS storage server (or its network interfaces) that all serve the identical NFS export path. The ESXi host then maps each server IP to a separate VMkernel adapter, distributing traffic and providing path redundancy. Adding multiple server IPs in this list is the mechanism that enables multipathing for NFS datastores.
ESXi host IP addresses are never entered into this field; the list targets the storage server endpoints, not the consuming hosts.
Dynamic Discovery is an iSCSI SendTargets mechanism used to automatically find iSCSI targets, and it has no role in NFS datastore configuration.
Static Discovery is an iSCSI concept for manually specifying target portals and is not applicable to NFS storage provisioning.
Concept tested: NFS datastore multipathing via multiple server IP addresses
