1
00:00:00,000 --> 00:00:01,290
In this section of the course,

2
00:00:01,290 --> 00:00:03,210
we're going to discuss the official seven step

3
00:00:03,210 --> 00:00:06,240
troubleshooting methodology that's presented by CompTIA.

4
00:00:06,240 --> 00:00:07,740
Now, up until this point in the course,

5
00:00:07,740 --> 00:00:09,270
we have focused on building your knowledge

6
00:00:09,270 --> 00:00:11,250
of how networks are supposed to be designed,

7
00:00:11,250 --> 00:00:12,810
configured, and operated.

8
00:00:12,810 --> 00:00:15,450
But in this section, we're going to start laying the foundation

9
00:00:15,450 --> 00:00:16,530
for the rest of the course

10
00:00:16,530 --> 00:00:18,270
as we start worrying about what to do

11
00:00:18,270 --> 00:00:19,890
when something inevitably breaks down

12
00:00:19,890 --> 00:00:21,420
inside of your networks.

13
00:00:21,420 --> 00:00:23,340
Now, to help us with this, CompTIA has developed

14
00:00:23,340 --> 00:00:26,100
a standardized seven step troubleshooting process

15
00:00:26,100 --> 00:00:27,930
that they recommend that you use when you're working

16
00:00:27,930 --> 00:00:29,370
as a network technician.

17
00:00:29,370 --> 00:00:31,770
After all, much of your day as a network technician

18
00:00:31,770 --> 00:00:33,600
is going to be spent answering trouble tickets

19
00:00:33,600 --> 00:00:36,240
or fixing problems that are found inside of your networks.

20
00:00:36,240 --> 00:00:37,470
To help us with all of this,

21
00:00:37,470 --> 00:00:39,750
we have the seven step troubleshooting methodology

22
00:00:39,750 --> 00:00:41,430
that we're going to be able to use to solve any problem

23
00:00:41,430 --> 00:00:43,920
that comes our way when working on our networks.

24
00:00:43,920 --> 00:00:45,330
So in this section,

25
00:00:45,330 --> 00:00:47,280
we're going to be focused solely on domain 5

26
00:00:47,280 --> 00:00:50,130
network troubleshooting and objective 5.1.

27
00:00:50,130 --> 00:00:52,740
Objective 5.1 states that you must be able to explain

28
00:00:52,740 --> 00:00:54,510
the troubleshooting methodology.

29
00:00:54,510 --> 00:00:56,880
Now, if you use the standard troubleshooting methodology,

30
00:00:56,880 --> 00:00:58,560
it's really going to help ensure that you're thinking

31
00:00:58,560 --> 00:01:01,200
through all the possible issues, developing a theory,

32
00:01:01,200 --> 00:01:02,370
creating a plan of action,

33
00:01:02,370 --> 00:01:04,410
and implementing it to successfully solve

34
00:01:04,410 --> 00:01:07,140
any kind of challenges you may face out in the field.

35
00:01:07,140 --> 00:01:08,790
So in this section of the course,

36
00:01:08,790 --> 00:01:10,290
we're going to be spending time going through each

37
00:01:10,290 --> 00:01:12,240
of the different steps one at a time,

38
00:01:12,240 --> 00:01:14,880
so you can best understand how they can be applied.

39
00:01:14,880 --> 00:01:17,610
These steps are first to identify the problem,

40
00:01:17,610 --> 00:01:20,430
second, to establish a theory of probable cause,

41
00:01:20,430 --> 00:01:23,040
third, to test the theory to determine the cause,

42
00:01:23,040 --> 00:01:25,650
fourth, to establish a plan of action to resolve the problem

43
00:01:25,650 --> 00:01:27,570
and identify potential effects.

44
00:01:27,570 --> 00:01:30,690
Fifth, to implement the solution or escalate as necessary,

45
00:01:30,690 --> 00:01:33,030
six, to verify full system functionality

46
00:01:33,030 --> 00:01:36,150
and if applicable, implement preventative measures,

47
00:01:36,150 --> 00:01:38,520
and seventh, document findings, actions,

48
00:01:38,520 --> 00:01:40,530
outcomes, and lessons learned.

49
00:01:40,530 --> 00:01:41,820
After that, we're going to walk through

50
00:01:41,820 --> 00:01:43,320
all seven steps one more time,

51
00:01:43,320 --> 00:01:44,910
as we work through a real world issue

52
00:01:44,910 --> 00:01:46,140
that you might come across one day

53
00:01:46,140 --> 00:01:47,700
when you're working in the field.

54
00:01:47,700 --> 00:01:49,800
Finally, we'll take a short quiz to see what you learned

55
00:01:49,800 --> 00:01:52,170
during this section of the course and review your answers

56
00:01:52,170 --> 00:01:54,060
to ensure you know why the right answers were right

57
00:01:54,060 --> 00:01:55,650
and the wrong answers were wrong.

58
00:01:55,650 --> 00:01:58,050
So if you're ready, let's get started with our coverage

59
00:01:58,050 --> 00:02:00,330
of the CompTIA seven step troubleshooting methodology

60
00:02:00,330 --> 00:02:01,830
in this section of the course.
