Which statement describes the effect of using higher timing templates in Nmap, such as -T4?

• A. Using higher timing templates increases speed but sacrifices stealth.
• B. It increases the number of retries.
• C. It uses a random scan order.
• D. It decreases the risk of detection.

Answer: (A)

Pushing Nmap to a higher timing template makes the scan more aggressive and faster by reducing the gaps between probe sends and increasing concurrent activity. This means the probe sequence loops through targets and ports more quickly, finishing the scan in less time. But that aggressiveness also makes the activity more conspicuous on the network: firewalls, intrusion detection systems, and even target hosts are more likely to notice the flurry of packets and react, which erodes stealth. In practice, you gain speed at the cost of being louder and easier to detect, which is why higher timing templates are described as increasing speed but sacrificing stealth.
