NS0-157 · Question #156
The Catalyst 2960 can be used only on the management network for clusters that have _____nodes.
The correct answer is E. 24. The Cisco Catalyst 2960 lacks the port density and throughput for cluster interconnect duties in a 24-node cluster, so NetApp restricts it to management network use only at that scale. The cluster interconnect for a 24-node cluster must use the Cisco Nexus 5020.

Why each option
The Cisco Catalyst 2960 lacks the port density and throughput for cluster interconnect duties in a 24-node cluster, so NetApp restricts it to management network use only at that scale. The cluster interconnect for a 24-node cluster must use the Cisco Nexus 5020.
A 12-node cluster is small enough that the Catalyst 2960 is not restricted to management-only use; the management-only restriction is applied at the 24-node threshold.
16 nodes is not the threshold at which NetApp imposes the management-only restriction on the Catalyst 2960 - the validated limit is 24 nodes.
18 nodes is the maximum node count for the Cisco Nexus 5010 cluster interconnect switch, not the threshold at which the Catalyst 2960 becomes management-only.
20 nodes is not the specified cluster size at which the Catalyst 2960 is restricted to management network use according to NetApp validated configurations.
A 24-node cluster requires a cluster interconnect switch with sufficient port count and bandwidth - a role the Catalyst 2960 cannot fulfill. NetApp therefore restricts the Catalyst 2960 to the management network only when the cluster reaches 24 nodes, requiring the Nexus 5020 to handle the cluster interconnect fabric.
