Explanation

In VMware Aria Operations for Logs (VCF Operations for Logs), the Primary Node acts as the cluster coordinator - it manages cluster-wide operations, handles the user interface, processes API requests, and directs how worker nodes function together. Worker Nodes (A) are responsible for data ingestion and log indexing, doing the heavy processing work but under the Primary Node's direction, not coordinating it. Replica Node (B) is not a defined node role in this architecture - it's a distractor borrowing terminology from database replication concepts. Data Node (D) is similarly not a named role in VCF Operations for Logs; it conflates this product with Elasticsearch cluster terminology, where "data node" is a real concept.

Memory tip: Think "Primary = Principal" - just as a school principal oversees the whole institution while teachers (workers) do the day-to-day work, the Primary Node oversees the cluster while Worker Nodes handle the actual log processing.
