Certified Ethical Hacker (CEH) Practice Question

During an external penetration test, you need to discover which TCP services a remote server exposes, but you must avoid completing the full three-way handshake so that service daemons generate as few log entries as possible. Which Nmap scan type should you choose?

  • TCP connect scan (-sT)

  • TCP ACK scan (-sA)

  • TCP SYN scan (-sS)

  • UDP discovery scan (-sU)
