I Have some questions regarding ata Gathering and Footprinting on a Targeted Website

1.Explain why the Whois tool is useful. 2. List some useful functions that are included in Sam Spade. Which do you think you will be mostly likely to use? 3. Explain what output is generated by the tracert command. Provide a scenario where you might use tracert as an investigative tool. 4. Provide a brief description of Sam Spade. Do you think Sam Spade is useful to security practitioners? 5. Do you think hackers might find Sam Spade equally useful? 6.

I would appreciate any help.
