NSE 7 – Enterprise Firewall 6.2 — Question 3

In which two states is a given session categorized as ephemeral? (Choose two.)

Answer options

• A. A TCP session waiting for FIN ACK.
• B. A TCP session waiting to complete the three-way handshake.
• C. A UDP session with packets sent and received.
• D. A UDP session with only one packet received.

Correct answer: B, D

Explanation

A TCP session waiting to complete the three-way handshake is considered ephemeral because it is not fully established yet. Additionally, a UDP session with only one packet received is also ephemeral since it does not maintain a stateful connection like TCP does. The other options describe more stable or completed session states.
