NFSv4.1 pNFS reduces traffic over which network?
The correct answer is A. cluster network. NFSv4.1 pNFS allows clients to directly access the storage node that owns their data, eliminating the need to proxy I/O across the internal cluster interconnect.

Why each option
NFSv4.1 pNFS allows clients to directly access the storage node that owns their data, eliminating the need to proxy I/O across the internal cluster interconnect.
In clustered ONTAP, when a client accesses data owned by a different node, that data would normally traverse the cluster (interconnect) network between nodes. pNFS provides clients with layout information so they connect directly to the owning node, reducing traffic on the cluster network.
The data network carries client-facing I/O and is not reduced by pNFS - pNFS optimizes the path clients use to reach storage nodes, not the volume of client traffic itself.
InfiniBand is a high-speed interconnect technology unrelated to the NFSv4.1 pNFS optimization path in ONTAP clusters.
The management network handles administrative traffic such as CLI and GUI connections and is unaffected by pNFS data path changes.
