https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/qos_dfsrv/configuration/15-mt/qos-dfsrv-15-mt-book/qos-dfsrv.htmlDifferentiated Services (DiffServ) is a protocol used to prioritize network traffic and manage Quality of Service (QoS) for network applications, including voice and video. DiffServ uses a set of codepoints to mark traffic and prioritize it based on its importance.
Each codepoint corresponds to a specific class of service (CoS) and has a different level of priority. The AF codepoints (Assured Forwarding) are commonly used for marking voice and video traffic in enterprise networks.
The AF codepoints are further divided into four sub-groups, AF11, AF12, AF13, and AF14, each with a different level of priority. The AF13 codepoint corresponds to the lowest priority among the AF codepoints and is the most likely to drop packets in a congested network.
Therefore, the answer to the question is A. AF13. If packets marked with the AF13 codepoint encounter network congestion, they are more likely to be dropped than packets marked with other AF codepoints.
