NSE 7 – SD-WAN 7.0 — Question 43

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

Answer options

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

Correct answer: B, C

Explanation

The correct answers are B and C because FEC enhances reliability on noisy links by correcting errors and it transmits parity packets that allow for the reconstruction of lost data. Options A and D are incorrect as they do not directly relate to the primary functions of FEC in improving data integrity and reliability.
