What is the maximum number of nodes supported for clustered ONTAP 8.2 serving both SAN and NAS protocols?
The correct answer is E. 8. Clustered ONTAP 8.2 supports up to 8 nodes when serving both SAN and NAS protocols simultaneously, which is a lower limit than NAS-only configurations.

Why each option
Clustered ONTAP 8.2 supports up to 8 nodes when serving both SAN and NAS protocols simultaneously, which is a lower limit than NAS-only configurations.
1 node describes a single-node cluster (non-HA), which is far below the supported maximum for mixed-protocol configurations.
2 nodes describes a single HA pair, which is valid but is not the maximum supported node count for mixed SAN and NAS.
4 nodes is below the actual maximum of 8 nodes supported for mixed SAN and NAS workloads in ONTAP 8.2.
6 nodes is not a defined architectural limit in clustered ONTAP 8.2 for SAN and NAS configurations.
In clustered ONTAP 8.2, the maximum supported cluster size for mixed SAN and NAS protocol configurations is 8 nodes. When SAN protocols are involved, the cluster node limit is more restrictive than a NAS-only deployment. NAS-only clusters in ONTAP 8.2 can scale up to 24 nodes, but adding SAN reduces the ceiling to 8.
24 nodes is the maximum for NAS-only clusters in ONTAP 8.2, but adding SAN protocol support reduces the limit to 8 nodes.
