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

  • Traffic Class
  • Class of Service

Explanation: 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.
