What does the -T2 (Polite) timing template do?

• A. Increases the scan speed to minimize total time
• B. Slows down the scan to use less bandwidth and resources
• C. Disables port scanning entirely
• D. Uses multiple threads to accelerate scanning

Answer: (B)

Timing templates in Nmap decide how aggressively probes are sent and how much workload the scan generates. The Polite template, used with -T2, is designed to be gentle on the network. It slows down the scan, reduces the rate of probes, and lets the scanner use fewer packets per second, which translates to using less bandwidth and fewer resources on both sides. This slower approach is helpful when you’re scanning sensitive networks, busy environments, or when you want to minimize disruption and avoid tipping off IDS/IPS. Because of the reduced probe rate, the scan takes longer to complete, but it’s much less likely to cause congestion or draw attention.

In contrast, higher-tolerance templates speed things up and can increase network load, while lower templates don’t imply disabling scanning or automatically increasing threading. The Polite setting is specifically about dialing back aggressiveness to be considerate of the target’s resources.
