To enable multi-cluster setup for NDB High Availability (HA), the administrator must configure the NDB Agent with a Network Profile. A Network Profile defines the networking settings (e.g., VLANs, IP ranges) that the NDB Agent uses to communicate across clusters. This is critical for multi-cluster HA, as it ensures consistent network configuration for replication, failover, and data synchronization between clusters. The Network Profile must be properly configured to handle inter-cluster traffic and latency requirements (e.g., < 25ms RTT).
Other options are irrelevant:
A. Name Prefix: Used for naming conventions, not network configuration.
C. Static VLAN: A component of a Network Profile, but not the full configuration needed.
D. Compute Profile: Defines VM resources (CPU, memory), not networking for HA.
Thus, the verified answer is B, aligning with multi-cluster HA networking needs.
