Explanation
The QoS profile assigns different classes and guaranteed bandwidth percentages to different applications. The QoS policy rules apply the QoS profile to the traffic based on the source and destination zones. The priority of a class is determined by its number, with lower numbers having higher priority. The bandwidth of a class is determined by its guaranteed percentage, with higher percentages having more bandwidth. Based on this information, DNS belongs to class 1 which has the highest priority (1) and the most bandwidth (40%). SSH belongs to class 4 which has the lowest priority (4) and the least bandwidth (5%). Therefore, DNS has a higher priority and more bandwidth than SSH. Similarly, Google-video belongs to class 2 which has the second highest priority (2) and the second most bandwidth (30%). WebEx belongs to class 3 which has the third highest priority (3) and the third most bandwidth (25%). Therefore, Google-video has a higher priority and more bandwidth than WebEx. References: :
