Full set: 251 questions

Answer options

A: Agent VM

B: HAProxy Correct answer

C: Repository DB

D: APIVM

Correct Answer:

B. HAProxy

Explanation

In Nutanix Database Service (NDB) Multi-cluster deployments, HAProxy is deployed on a dedicated VM to provide load balancing and high availability for database connections across multiple clusters. This component acts as a reverse proxy, distributing client requests among available database instances and ensuring continuous service availability. The dedicated VM deployment ensures isolation and optimal performance for this critical networking component that manages traffic distribution in multi-cluster environments.

Why Incorrect

A. Agent VM - Deployed on database server VMs, not as a dedicated VM component.
C. Repository DB - Part of the NDB server infrastructure, not a separate dedicated VM.
D. APIVM - Not a standard NDB component; API services run on the NDB server.
