Explanation:
Campus LAN QoS Considerations
For the access layer of the campus LAN, you can classify and mark frames or packets to apply
quality of service (QoS) policies in the distribution or at the enterprise edge. Classification is a
fundamental building block of QoS and involves recognizing and distinguishing between different
traffic streams. For example, you distinguish between HTTP/HTTPS, FTP, and VoIP traffic.
Without classification, all traffic is treated the same.
QoS Considerations for Voice and Video in the WAN
In addition to providing adequate bandwidth for all required applications, traffic classification, and voice priority queuing and scheduling, the WAN infrastructure typically requires additional mechanisms
