The QoS design and implementation process comprises of the following steps:
1. characterize network
2. implement policy
3. determine customer priorities/QoS policy
4. monitor network
What is the correct order for these steps?
A.
4, 1, 3, 2
B.
1, 3, 2, 4
C.
3, 1, 2, 4
D.
1, 2, 3, 4
E.
4, 3, 1, 2
Explanation:
The process begins with determining priorities – what traffic should get more bandwidth? Less loss, jitter, and delay? The policies, however, typically define classes of traffic in general terms; you need to know the specific of the traffic patterns so that you can configure the QoS tools to classify the traffic correctly. At Step 2, you characterize the traffic, which enables you to know how to configure the various classification features of the QoS tools. Then you can proceed with Step3, where you actually configure the QoS tools. Finally, you ceed to monitor the network (Step 4) to determine whether you met the stated policy goals you determined in Step 1. The process continues over time, with the quality of the QoS implementation improving with each cycle.
