An administrator enables NDB Multi-cluster. Which NDB Service component is deployed on a dedicated VM?

When an administrator enables NDB Multi-cluster functionality, certain components are deployed or

reconfigured to support the distributed environment. HAProxy (High Availability Proxy) is a critical

component that manages load balancing and secure communication across clusters. In a multi-

cluster setup, HAProxy is deployed on a dedicated VM to ensure efficient traffic distribution and high

availability for NDB services, such as API calls and GUI access, across the clusters. This dedicated

deployment enhances scalability and resilience.

Option A (Agent VM) is incorrect because Agent VMs are typically deployed on managed database

VMs, not as dedicated NDB service components in multi-cluster setups.

Option B (HAProxy) is correct as it is specifically deployed on a dedicated VM to handle load

balancing in a multi-cluster NDB environment.

Option C (Repository DB) is incorrect because the Repository DB is part of the NDB control plane and

not necessarily deployed on a separate VM for multi-cluster purposes.

Option D (APIVM) is incorrect because the API VM is part of the core NDB infrastructure but not

specifically deployed as a dedicated VM for multi-cluster enablement.
