One of the new topics on the new CCNA R/S v3 exam is Quality of Service (QoS). Having taught QoS for many years, I’ve noticed that one of the topics students find most challenging is QoS Traffic Markings.
This topic is all about how the binary math works behind the scenes to mark our traffic with specific levels of priority. So, to help demystify this topic, I created a new video (which is part of my upcoming CCNA R/S v3 Complete Video Course), and I wanted to share it with you. Enjoy!
