A storage administrator requires MPIO and has asked the network administrator to assist by configuring the managed switch appropriately. Which of the following will the network administrator be using?

iSCSI is a block-level storage protocol that uses MPIO for redundant paths, but the question specifies NFSv4 is what the network administrator will be 'using' or supporting.

VLANs are a network segmentation mechanism used by network administrators to isolate traffic, and while crucial for configuring switches to support MPIO for storage, they are a means to an end rather than the specific storage protocol being enabled.

NFSv2 is an older version of the Network File System protocol and would not typically be the chosen protocol for modern storage environments requiring advanced features like multipathing.

When a storage administrator requires multipathing (MPIO) for Network File System version 4 (NFSv4) access, the network administrator configures the managed switch to provide redundant network paths, such as using link aggregation or dedicated VLANs, to ensure high availability and performance for the NFSv4 storage traffic.
