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 supports MPIO, but it is not the protocol identified as the answer for the network administrator's switch configuration in this specific scenario.

VLANs are a switch segmentation feature used to isolate traffic and are not themselves a storage protocol capable of providing multipath I/O functionality.

NFSv2 is a legacy, stateless NFS protocol that lacks the session management and parallel data path capabilities required for MPIO support that NFSv4 provides.

NFSv4.1 introduced pNFS (parallel NFS), which supports multiple simultaneous data paths and enables true MPIO-style multipathing for NFS storage. The network administrator must configure the managed switch with settings such as dedicated VLANs, jumbo frames, and flow control to properly carry NFSv4 multipath traffic between storage and compute nodes.
