NSE 7 – Network Security Technologies 7.2 — Question 59

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

Answer options

• A. A UDP session with only one packet received
• B. A UDP session with packets sent and received
• C. A TCP session waiting for the SYN ACK
• D. A TCP session waiting for FIN ACK

Correct answer: A, C

Explanation

An ephemeral session is characterized by its temporary nature. A UDP session with only one packet received (A) is considered ephemeral since it does not establish a long-term connection, while a TCP session waiting for SYN ACK (C) is also transient as it indicates the connection establishment phase. The other options (B and D) involve more established connections or ongoing sessions.
