Which statement is true regarding a single node cluster with Data ONTAP 8.2 or later?

A single-node cluster cannot grow beyond one node; converting to a multi-node cluster is not a supported operation in this configuration.

Single-node clusters are explicitly supported starting with Data ONTAP 8.2, so stating they are not supported is incorrect.

Starting with Data ONTAP 8.2, NetApp officially supports single-node clusters as a deployment model, which allows use of the clustered ONTAP feature set on a standalone controller. However, this configuration is permanently limited to a single node - there is no supported upgrade path to add a second node and convert it into a multi-node cluster, making it a fixed, non-expandable architecture.

10GbE cross connects between an on-board NIC and a PCIe card describe a cluster interconnect requirement for multi-node clusters, not a defining characteristic of single-node cluster support.
