NetApp Certified Data Administrator (NCDA) – ONTAP NAS — Question 17

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

Answer options

• 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.

Correct answer: C, E

Explanation

Option C is correct because maintaining the health of more than half of the existing nodes is essential to ensure stability when new nodes are added. Option E is also correct as it emphasizes that for a switchless configuration, all necessary components must be in place before expansion. The other options either misstate requirements or introduce unnecessary components that are not needed for adding nodes in this context.
