An administrator with ID123456789 is getting complaints about pixelation, smearing, and pulsing in video calls between two offices connected through a WAN.

Assuming QoS is configured on the WAN connection, which classification marks the video traffic according to the Cisco QoS baseline?

  • A AF41
  • B CS3
  • C EF
  • D AF31
