FCSS – Network Security Specialist 7.6 — Question 6

Which two protocol states indicate that traffic is bidirectional? (Choose two.)

Answer options

• A. proto_state=05 for a TCP session.
• B. proto_state=01 for a TCP session.
• C. proto_state=01 for a UDP session.
• D. proto_state=00 for an ICMP session.

Correct answer: A, D

Explanation

The correct answers, A and D, signify that the respective protocol states indicate bidirectional traffic. proto_state=05 for TCP shows an established connection allowing two-way communication, while proto_state=00 for ICMP implies that messages can be sent and received. The other options do not indicate bidirectional traffic.
