CompTIA Security+ (SY0-401) — Question 6

Which the following flags are used to establish a TCP connection? (Choose two.)

Answer options

• A. PSH
• B. ACK
• C. SYN
• D. URG
• E. FIN

Correct answer: B, C

Explanation

The correct flags for establishing a TCP connection are SYN and ACK. The SYN flag is used to initiate a connection request, while the ACK flag is used to acknowledge the receipt of a SYN request. PSH, URG, and FIN serve different purposes in TCP communication and are not involved in the initial connection establishment.
