Answer - D - A honeypot is a system which uses a fake server and sends alarms when an intruder tries to attack the network.

Key Takeaway: A honeypot is a trap set to detect, deflect, or counteract attempts at unauthorized use of information systems. It consists of a computer, data, or a network site that appears to be part of a network, but is actually isolated and monitored. This contains information that is of value to attackers. Honeypot serves as a valuable surveillance and early-warning tool.
