A.Xmas Scan
B.Null Scan
C.TCP Connect Scan
D.Stealth / SYN Scan
Correct Answer: Stealth / SYN Scan
Explanation:
A SYN scan involves sending a SYN packet and waiting for a SYN-ACK, but sending a RST instead of an ACK to close the connection, never completing the full 3-way handshake.
Incorrect! Try again.
12What distinguishes a 'TCP Connect' scan from a 'SYN' scan?
A.TCP Connect is more stealthy
B.TCP Connect completes the full 3-way handshake
C.TCP Connect requires root privileges
D.TCP Connect uses UDP packets
Correct Answer: TCP Connect completes the full 3-way handshake

A.SYN, ACK, RST
B.No flags set
C.SYN only
