Explanation

DNS Hijacking Explained

DNS hijacking (Option D) is correct because Joe is being redirected to a fraudulent website that mimics his banking site - the telltale signs are the different URL and missing security certificate, which indicate his DNS queries are being intercepted and resolved to a malicious IP address instead of the legitimate bank's server.

Why the distractors are wrong:

• A (DHCP Spoofing) involves a rogue server assigning false network configuration (IP addresses, gateway info) to devices - it doesn't directly redirect specific websites
• B (DoS Attack) overwhelms a system or network to make it unavailable entirely - Joe can still access a site, just a fake one
• C (ARP Cache Poisoning) manipulates MAC address tables on a local network to intercept traffic - it operates at Layer 2 and wouldn't typically produce a different-looking URL

Memory Tip: Think DNS = Directory Navigation System - hijacking means someone replaced the correct "directory listing" with a fake address, just like changing a street sign to redirect you to the wrong destination. If the URL looks wrong, think DNS hijacking first on the exam.
