What is the maximum number of nodes a SAN cluster in DOT 8.1 can have?
The correct answer is C. 6. In Data ONTAP 8.1, SAN clusters are limited to a maximum of 6 nodes due to protocol scaling constraints in that release.

Why each option
In Data ONTAP 8.1, SAN clusters are limited to a maximum of 6 nodes due to protocol scaling constraints in that release.
A single node cannot form a cluster by definition.
DOT 8.1 SAN clusters support more than 2 nodes, making this an undercount.
Data ONTAP 8.1 imposed a hard limit of 6 nodes for SAN cluster configurations, reflecting the architectural and protocol scalability boundaries of that release. This limit applied specifically to SAN-enabled clustered environments, distinguishing it from NAS-only configurations that had different node maximums.
8 nodes exceeds the maximum 6-node limit for DOT 8.1 SAN clusters.
16 nodes is well above the supported 6-node ceiling for DOT 8.1.
24 nodes far exceeds the DOT 8.1 SAN cluster maximum and corresponds to later ONTAP versions.
32 nodes is unsupported in DOT 8.1 and corresponds to much newer ONTAP releases.
