1
00:00:06,960 --> 00:00:08,550
- Welcome to module five,

2
00:00:08,550 --> 00:00:10,890
hardware and network troubleshooting.

3
00:00:10,890 --> 00:00:13,650
This is without a doubt,
the most important piece

4
00:00:13,650 --> 00:00:17,790
of the A+ 220-1101 puzzle.

5
00:00:17,790 --> 00:00:20,040
Coming in at 29%,

6
00:00:20,040 --> 00:00:23,640
it is the largest domain
of the Core 1 Exam.

7
00:00:23,640 --> 00:00:25,650
And I can guarantee you that you will see

8
00:00:25,650 --> 00:00:29,640
plenty of troubleshooting
scenario-oriented questions

9
00:00:29,640 --> 00:00:31,170
on the exam.

10
00:00:31,170 --> 00:00:34,260
Study this domain carefully.

11
00:00:34,260 --> 00:00:36,930
This module consists of eight lessons.

12
00:00:36,930 --> 00:00:39,150
We begin with the CompTIA six-step

13
00:00:39,150 --> 00:00:41,160
troubleshooting methodology,

14
00:00:41,160 --> 00:00:44,670
and apply that throughout
the rest of the course.

15
00:00:44,670 --> 00:00:45,660
Within these lessons,

16
00:00:45,660 --> 00:00:49,980
you'll also learn about ESD
prevention, testing tools,

17
00:00:49,980 --> 00:00:52,890
how to troubleshoot
desktop and mobile systems,

18
00:00:52,890 --> 00:00:55,020
storage drive troubleshooting,

19
00:00:55,020 --> 00:00:59,280
and how to solve problems
related to video and printers,

20
00:00:59,280 --> 00:01:02,583
plus wired and wireless
network troubleshooting.

21
00:01:03,480 --> 00:01:04,680
To close out the module,

22
00:01:04,680 --> 00:01:07,500
we cover some exam tips and techniques,

23
00:01:07,500 --> 00:01:09,363
and some sample questions.

24
00:01:10,470 --> 00:01:13,590
I really can't stress how
important this module is.

25
00:01:13,590 --> 00:01:17,790
Not only for the exam,
but for the IT field.

26
00:01:17,790 --> 00:01:20,130
Most of what we do as tech support people

27
00:01:20,130 --> 00:01:24,900
and help desk technicians
is solve problems.

28
00:01:24,900 --> 00:01:28,533
So get your brain in gear and
let's get troubleshooting.
