When a two-node cluster is expanded, which cluster configuration would be supported?
A.
a 4-node switched cluster
B.
a 4-node switchless cluster
C.
a 3-node switched cluster
D.
a 3-node switchless cluster
Explanation:
If you are adding nodes to a two-node switchless cluster, you must have installed and configured the cluster
management and interconnect switches before adding additional nodes.
The switchless cluster functionality is supported only in a two-node cluster.

Correct is A, The only odd number configuration which is supported is ‘1’ so ‘3’ is incorrect here and cluster interconnect switches are mandatory if more than two nodes are there in cluster.

Read first…
After a cluster is created, you can expand it by adding nodes to it. You add only one node at a time.Nodes must be in even numbers so that they can form HA pairs. After you start to add a node to the cluster, you must complete the process. The node must be part of the cluster before you can start to add another node.
If you are adding nodes to a two-node switchless cluster, you must have installed and configured the cluster management and interconnect switches before adding additional nodes.
