Explain how Quality of Service (QoS) works.
What will be an ideal response?
QoS, a Layer 2 service, works with 802.1Q trunks to prioritize traffic, applying a Class of Service (CoS) priority to a certain physical port. As traffic passes through the port to a trunk line, it receives an allocated amount of bandwidth determined by the priority (the higher the value from 0 to 7, the more bandwidth).
