Node.js - Cluster Module

Consider this Node.js cluster code snippet:

const cluster = require('cluster');
const http = require('http');

if (cluster.isPrimary) {
  cluster.fork();
  cluster.fork();
} else {
  http.createServer((req, res) => {
    res.end('Worker ' + process.pid);
  }).listen(8000);
}

What will happen when you visit http://localhost:8000 multiple times?

AYou will see responses from different worker process IDs

BOnly one worker will handle all requests

CThe server will crash because of multiple forks

DYou will get a syntax error on startup

Step-by-Step Solution

Solution:

Step 1: Understand cluster.fork creates workers
Two workers are created, each running the HTTP server on port 8000.
Step 2: Recognize load balancing behavior
Requests are distributed between workers, so responses show different process IDs.
Final Answer:
You will see responses from different worker process IDs -> Option A
Quick Check:
Multiple workers share port, respond with different PIDs [OK]

Quick Trick: Multiple forks = multiple workers respond differently [OK]

Common Mistakes:

Thinking only one worker handles all requests
Assuming server crashes due to multiple forks
Expecting syntax errors from this code
