CIT v Summary A troubleshooter using the bottom-up approach starts with the physical layer and works up toward the application layer until the cause of the problem is located. A troubleshooter using the top-down approach starts with the application layer and works down toward the physical layer until the cause of the problem is located. A troubleshooter implementing a divide and conquer approach starts at a layer in the middle of the logical model and works up and down the layers. When a troubleshooter selects an effective troubleshooting approach to solve a network problem, the problem is resolved in a quicker and more cost-effective manner.
