An application is hosted on a three-node cluster in which each server has identical compute...

Comprehensive and Detailed Explanation From Exact Extract:

Weighted load balancing allows distribution of traffic based on server capacity or assignedweights. In this case, the new node should receive a weight of 3, and each of the three older nodes a weight of 1. This ensures the new node handles the same total number of requests as the other three combined (3:1:1:1).

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Load Balancing Algorithms and Traffic Distribution”:

“Weighted load balancing accounts for node capacity, distributing requests proportionally according to performance capability or administrator-defined weights.”

Other options:

A. Round-robin sends traffic equally to all servers regardless of capacity.

B. Load-based requires dynamic performance measurement and is more complex.

C. Least connections may work in certain cases, but doesn’t guarantee proportional traffic split based on server performance.
