How can clustering be combined with load balancing to improve Node.js server performance?

hard📝 Application Q9 of 15
Node.js - Cluster Module
How can clustering be combined with load balancing to improve Node.js server performance?
ACluster converts sync code to async; load balancer forks workers.
BCluster compresses data; load balancer caches responses.
CCluster handles database queries; load balancer manages CPU cores.
DCluster creates workers; load balancer distributes requests evenly among them.
Step-by-Step Solution
Solution:

  1. Step 1: Understand clustering role

    Clustering creates multiple worker processes to handle requests.

  2. Step 2: Understand load balancer role

    Load balancer distributes incoming requests evenly to workers for efficiency.

  3. Final Answer:

    Cluster creates workers; load balancer distributes requests evenly among them. -> Option D

  4. Quick Check:

    Clustering + load balancing = efficient request handling [OK]
Quick Trick: Load balancer spreads requests across cluster workers [OK]
Common Mistakes:
  • Confusing clustering with data compression
  • Misunderstanding load balancer functions
  • Mixing roles of cluster and load balancer
