What two fields are available in IPv4 and IPv6 headers to mark packets for QoS? (Choose two.)

  • Class of Service
  • Traffic Class
  • Type of Service
  • Priority
  • VLAN ID
    Answers Explanation & Hints:

    IPv4 uses an 8-bit Type of Service field to mark packets at Layer 3 and IPv6 uses an 8-bit Traffic Class field to mark packets at Layer 3. The fields are used by receiving devices to forward the packets based on the appropriate assigned QoS policy.
