Node.js - Cluster Module

Which of the following is the correct way to create a cluster in Node.js?

Aconst cluster = require('cluster'); cluster.fork();

Bconst proxy = require('proxy'); proxy.create();

Cconst http = require('http'); http.listenCluster();

Dconst cluster = require('cluster'); cluster.createServer();

Step-by-Step Solution

Solution:

Step 1: Recall Node.js cluster module usage
The cluster module is required with require('cluster') and workers are created with cluster.fork().
Step 2: Check other options for correctness
There is no proxy module by default, http.listenCluster() and cluster.createServer() are invalid methods.
Final Answer:
const cluster = require('cluster'); cluster.fork(); -> Option A
Quick Check:
cluster.fork() creates workers [OK]

Quick Trick: Use cluster.fork() to create workers in Node.js [OK]
