Q: Which header field in the Internet Protocol (IP) v6 is used to identify a datagram’s quality of service level?
- Flow label
- Payload length
- Next header
- Version
Explanation: The “Traffic Class” field is the component of an Internet Protocol version 6 (IPv6) header that is responsible for determining the quality of service level associated with a datagram. The “Flow Label” field and the “Traffic Class” field are both components of the IPv6 header’s methods for controlling traffic flow and managing traffic, respectively. It is possible to prioritize and discriminate between several classes or levels of service for IPv6 datagrams via the Traffic Class field.
