# L2- L3 Service and Support

Troubleshooting individual machines in the environment falls to the front-line soldiers of the Help Desk or Call Center. In this learning path, we will use a series of use case examples, inspired by true stories, to illustrate key concepts that are common to Service and Support professionals, Field Technicians, and other hands-on L2 and L3 information technology workers.

By the end of this course, you will be able to use SysTrack tools to investigate the root cause of complex computer issues on end-user machines.
