After nearly a year I have completed my CompTIA A + Essentials and CompTIA A+ Depot (220-604) Technician with 785 out of 900. The Depot technician is one of the two hardest electives on the A + because it deals with the difficult tasks of a bench technician which in clued configuring network infrastructure and Installation and configuration of both clients and servers as well as maintaining and feature proofing network infrastructure.
