In clustered Data ONTAP 8.2, what is the maximum number of cluster nodes if any SAN protocols are being used?
The correct answer is D. 8 nodes. In clustered Data ONTAP 8.2, activating any SAN protocol (FC, FCoE, or iSCSI) caps the cluster at 8 nodes due to architectural constraints on SAN traffic handling across nodes.

Why each option
In clustered Data ONTAP 8.2, activating any SAN protocol (FC, FCoE, or iSCSI) caps the cluster at 8 nodes due to architectural constraints on SAN traffic handling across nodes.
2 nodes describes an HA pair or MetroCluster minimum, not the SAN protocol ceiling in cDOT 8.2.
4 nodes is not a defined architectural limit for SAN in clustered Data ONTAP 8.2.
6 nodes is not a recognized node-count boundary for any SAN or NAS configuration in cDOT 8.2.
NetApp clustered Data ONTAP 8.2 enforces a hard limit of 8 nodes when any SAN protocol is enabled, because SAN requires stricter inter-node coordination and resource reservation. This is a documented scalability boundary specific to SAN-enabled configurations. Without SAN protocols, the cluster can scale to the full 24-node maximum.
10 nodes exceeds the 8-node limit imposed when SAN protocols are active in cDOT 8.2.
24 nodes is the maximum cluster size for NAS-only deployments, not for clusters running SAN protocols.
