Which combination of preinstallation data items is explicitly required for a cluster?

• A. Management IP addresses, gateway IP address, and cluster name
• B. Management IP addresses only
• C. Gateway IP address and cluster name only
• D. Gateway IP address only

Answer: (A)

Before installing a NetApp cluster, you need the items that identify and reach the cluster’s management plane. A management IP address is what you use to connect to and manage the cluster. The gateway IP address ensures the management traffic can reach the cluster from networks outside the local subnet. The cluster name provides a unique identifier for the cluster in the environment and configuration records. Without the management IP, you have no way to access the cluster; without the gateway, routes to and from the management network may be missing; without a cluster name, the cluster cannot be uniquely identified in management tasks. Therefore, having management IP addresses, a gateway IP address, and a cluster name together is required. The other options miss one or more of these essential items.
