Node.js - Cluster Module
Which Node.js code snippet correctly creates a simple cluster using the cluster module?
Aconst cluster = import('cluster'); cluster.start();
Bconst cluster = require('cluster'); cluster.create();
Cimport cluster from 'cluster'; cluster.run();
Dconst cluster = require('cluster'); if (cluster.isMaster) { cluster.fork(); }
Step-by-Step Solution
Solution:
  1. Step 1: Check correct import syntax

    Node.js uses require('cluster') to import the cluster module.
  2. Step 2: Verify cluster usage

    cluster.isMaster checks if current process is master, then cluster.fork() creates a worker.
  3. Final Answer:

    const cluster = require('cluster'); if (cluster.isMaster) { cluster.fork(); } -> Option D
  4. Quick Check:

    Correct import and fork method = const cluster = require('cluster'); if (cluster.isMaster) { cluster.fork(); } [OK]
Quick Trick: Use require and cluster.isMaster with cluster.fork() [OK]
Common Mistakes:
  • Using import instead of require in Node.js
  • Calling non-existent cluster methods like start() or create()
  • Missing the cluster.isMaster check
