The Nmap option `-T4` is a faster timing choice, and its use should take account of network rate limits.

### Why this is right The activity identifies `-T4` as a faster timing option and warns users to consider rate limits. Timing changes the pace of probes; it does not identify a service or save scan output. ### The concept Scan pacing affects how quickly probes are sent and can influence network load and the likelihood of missed or altered observations. A faster setting is not automatically appropriate for every environment. Use the timing choice allowed by the assessment and account for the target network's constraints. ### Terms - **Nmap**: Network Mapper. A tool for network discovery and scanning. - **Rate limit**: A restriction on how quickly traffic or requests may be sent or accepted. ### Remember A faster scan still needs to respect the agreed testing pace.
