Show Suggested Answer

Suggested Answer: C

Understanding protocol states:

proto_state=00: Indicates no traffic or a closed session.

proto_state=01: Typically indicates one-way ICMP traffic or a partially established TCP session.

proto_state=10: Indicates an established TCP session, where the session has completed the three-way handshake and both sides can send and receive data.

proto_state=11: Often indicates a fully established and active bidirectional session.

Explanation of correct answer:

proto_state=10 is the correct indication for an established TCP session as it signifies that the session is fully established and active.

Hmm, this is tricky. I'm not too familiar with protocol states, but I'm going to go with option B. Sounds the most logical to me.

Option C makes the most sense. proto_state=10 indicates an established TCP session. The other options just don't seem right.

I think option B is correct. proto_state=01 indicates an established TCP session, not one-way ICMP traffic.
