   What does forward error correction addresses in Cisco SD-WAN?

   • Areduced application performance degradation related to service degradation
   • Bapplications with occasional invalid data input and poor performance
   • Ctraffic flows with increased delay over a particular transport
   • Dinefficient traffic forwarding caused by inbound shapers

   Show answer

   Answer: A

   Explanation

   A Forward Error Correction (FEC) is a mechanism to recover lost packets on a link by sending extra “parity” packets for every group of 4 packets. As long as the receiver receives a subset of packets in the group (at-least N-1) and the parity packet, up to a single lost packet in the group can be recovered
