[Solved] Given this code snippet:const cluster = require('cluster'); if (cluster.isMaster) { cluster.fork(); cluster.fork(); } else { console.log('Worker started'); }Why might the workers never start properly? | Node.js

Node.js - Cluster Module

Given this code snippet:

const cluster = require('cluster');
if (cluster.isMaster) {
  cluster.fork();
  cluster.fork();
} else {
  console.log('Worker started');
}

Why might the workers never start properly?

ABecause the master process forgot to require('http')

BBecause the workers have no code to keep them alive

CBecause cluster.fork() is called inside the else block

DBecause cluster.isMaster is always false

Step-by-Step Solution

Solution:

Step 1: Analyze worker code behavior
The workers only log 'Worker started' and then exit immediately because no server or event loop keeps them alive.
Step 2: Understand cluster.fork usage
cluster.fork() is correctly called in master block, so workers start but exit quickly.
Final Answer:
Because the workers have no code to keep them alive -> Option B
Quick Check:
Workers exit if no server or event loop runs [OK]

Quick Trick: Workers need active code (like server) to stay alive [OK]
