- Welcome to module five,
hardware and network troubleshooting.
This is without a doubt, the most important piece
of the A+ 220-1101 puzzle.
Coming in at 29%,
it is the largest domain of the Core 1 Exam.
And I can guarantee you that you will see
plenty of troubleshooting scenario-oriented questions
on the exam.
Study this domain carefully.
This module consists of eight lessons.
We begin with the CompTIA six-step
troubleshooting methodology,
and apply that throughout the rest of the course.
Within these lessons,
you'll also learn about ESD prevention, testing tools,
how to troubleshoot desktop and mobile systems,
storage drive troubleshooting,
and how to solve problems related to video and printers,
plus wired and wireless network troubleshooting.
To close out the module,
we cover some exam tips and techniques,
and some sample questions.
I really can't stress how important this module is.
Not only for the exam, but for the IT field.
Most of what we do as tech support people
and help desk technicians is solve problems.
So get your brain in gear and let's get troubleshooting.
