You are adding nodes to an existing cluster.
In this scenario, which three statements are correct? (Choose three.)

A.
If you are adding a second node to a single-node cluster, the second node must have been
installed, but the cluster network can be configured later.

B.
You must add a cluster switch for every two nodes.

C.
If you are adding nodes to a multiple-node cluster, more than half of the existing nodes in the
cluster must be healthy.

D.
The switchless cluster functionality is supported only in a single or two-node cluster.

E.
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.

Explanation:
C: If you are adding nodes to a multiple-node cluster, more than half of the existing
nodes in the cluster must be healthy (indicated by cluster show).
E: 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.
Incorrect:
not A: If you are adding a second node to a single-node cluster, the second node must be
installed, and the cluster network must be configured.
Not D: The switchless cluster functionality is supported only in a two-node cluster. Adding nodes to the cluster
