Node.js - Cluster Module

Consider this Node.js cluster code snippet:

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

if (cluster.isMaster) {
  cluster.fork();
  cluster.fork();
} else {
  http.createServer((req, res) => {
    res.end(`Worker ${process.pid} handled request`);
  }).listen(8000);
}

What will happen when you send multiple requests to port 8000?

ARequests will be handled by both worker processes, distributing load

BOnly the first worker will handle all requests, the second is idle

CThe master process will handle requests directly

DThe server will crash because multiple workers listen on the same port

Step-by-Step Solution

Solution:

Step 1: Understand cluster.fork() behavior
Calling cluster.fork() creates worker processes that share the same server port.
Step 2: Analyze request handling in workers
Both workers listen on port 8000 and Node.js load balances requests between them automatically.
Final Answer:
Requests will be handled by both worker processes, distributing load -> Option A
Quick Check:
Multiple workers share port and balance requests [OK]

Quick Trick: Multiple forks share port and balance requests [OK]

Common Mistakes:

Thinking only one worker handles all requests
Assuming master handles requests directly
Believing server crashes due to port sharing
