what type of scan should you run to get very reliable results?

You are performing a port scan with nmap. You are in hurry and conducting the scans at the fastest possible speed. However, you don’t want to sacrifice reliability for speed. If stealth is not an issue, what type of scan should you run to get very reliable results?

A.
XMAS scan

B.
Stealth scan

C.
Connect scan

D.
Fragmented packet scan

Explanation:
A TCP Connect scan, named after the Unix connect() system call is the most accurate scanning method. If a port is open the operating system completes the TCP three-way handshake, and the port scanner immediately closes the connection.
