What type of attack can occur after STP manipulation?

• A. Traffic redirection to the attacker's computer
• B. DNS spoofing
• C. Password brute-force
• D. ARP cache poisoning

Answer: (A)

Manipulating Spanning Tree Protocol can force a different path through a switched network by spoofing BPDUs to influence which switch becomes the root and how ports are designated. If an attacker can make the network prefer a path through their device, traffic will be redirected to the attacker's computer, enabling interception or modification—a classic man-in-the-middle effect on a LAN. That direct consequence is why this option is the best fit for what can occur after STP manipulation. DNS spoofing targets name resolution, brute-force attacks seek passwords, and ARP cache poisoning is a separate technique that could be used after interception, but STP manipulation specifically leads to traffic redirection through the attacker’s machine.
