CompTIA DataX (CNX-001) — Question 44

An application is hosted on a three-node cluster in which each server has identical compute and network performance specifications. A fourth node is scheduled to be added to the cluster with three times the performance as any one of the preexisting nodes. The network architect wants to ensure that the new node gets the same approximate number of requests as all of the others combined. Which of the following load-balancing methodologies should the network architect recommend?

Answer options

• A. Round-robin
• B. Load-based
• C. Least connections
• D. Weighted

Correct answer: D

Explanation

The weighted load-balancing method is appropriate here because it allows the architect to assign a higher weight to the new node, reflecting its greater performance capacity. This ensures that the new node receives a proportionate number of requests compared to the existing nodes. The other methods, like round-robin and least connections, do not account for the differences in server performance, which could lead to an imbalance in request distribution.
