NSE 7 – SD-WAN 7.2 — Question 29

What are two benefits of using forward error correction (FEC) in IPsec VPNs? (Choose two.)

Answer options

• A. FEC can leverage multiple IPsec tunnels for parity packets transmission.
• B. FEC transmits parity packets that can be used to reconstruct packet loss.
• C. FEC improves reliability of noisy links.
• D. FEC supports hardware offloading.

Correct answer: B, C

Explanation

The correct answers are B and C because FEC provides a method for recovery by sending parity packets that help reconstruct lost data (B), and it also enhances the reliability of connections that are prone to noise (C). Options A and D are incorrect as they do not directly relate to the primary functions and benefits of FEC.
