In VMware Cloud Foundation (VCF) Operations, which node type is responsible for providing fault tolerance for administrative functions within the VCF Operations cluster?

Question

Options

• APrimary Node
• BWitness Node
• CReplica Node
• DData Node

• A
  7% (2)
• C
  90% (27)
• D
  3% (1)

Explanation

Replica Nodes in VCF Operations exist specifically to mirror the Primary Node's administrative data and services, allowing the cluster to maintain fault tolerance - if the Primary Node fails, the Replica Node can take over administrative functions without losing continuity.

Option A (Primary Node) is wrong because it is the node being protected, not the protector - it handles core analytics and administrative coordination but has no built-in redundancy role itself. Option B (Witness Node) is wrong because it serves as a quorum tie-breaker in stretched cluster scenarios, not as a fault-tolerant mirror of admin functions. Option D (Data Node) is wrong because Data Nodes exist to scale out collection and analytics capacity, not to provide high availability for administrative services.

Memory tip: Think of it like a "replica" in a database - a Replica Node replicates the Primary to keep admin functions alive. "Replica = redundancy."
