What are two benefits of using forward error correction (FEC) in IPsec VPNs? (Choose two.)
Forward Error Correction (FEC) in IPsec VPNs is beneficial as it transmits parity packets that can be used to reconstruct packet loss, thereby improving the reliability of the VPN connection. Additionally, FEC improves the reliability of noisy links by correcting errors without the need for retransmission, ensuring a more robust and stable connection in environments with high error rates.

A. wrong - doesn't make sense B. correct - that is the main reason of using FEC on ipsec overlays C. correct - that is the main reason of using FEC on ipsec overlays D. wrong - once you enable FEC on a policy offloading is automatically disabled
Underlay: Refers to the physical infrastructure of the network Overlay: Refers to a virtual network layer that is built on top of the underlay infrastructure. R=>D= Therefore there are 4 virtual overlay interfaces
