In this section of the course,
we're going to discuss the official seven step
troubleshooting methodology that's presented by CompTIA.
Now, up until this point in the course,
we have focused on building your knowledge
of how networks are supposed to be designed,
configured, and operated.
But in this section, we're going to start laying the foundation
for the rest of the course
as we start worrying about what to do
when something inevitably breaks down
inside of your networks.
Now, to help us with this, CompTIA has developed
a standardized seven step troubleshooting process
that they recommend that you use when you're working
as a network technician.
After all, much of your day as a network technician
is going to be spent answering trouble tickets
or fixing problems that are found inside of your networks.
To help us with all of this,
we have the seven step troubleshooting methodology
that we're going to be able to use to solve any problem
that comes our way when working on our networks.
So in this section,
we're going to be focused solely on domain 5
network troubleshooting and objective 5.1.
Objective 5.1 states that you must be able to explain
the troubleshooting methodology.
Now, if you use the standard troubleshooting methodology,
it's really going to help ensure that you're thinking
through all the possible issues, developing a theory,
creating a plan of action,
and implementing it to successfully solve
any kind of challenges you may face out in the field.
So in this section of the course,
we're going to be spending time going through each
of the different steps one at a time,
so you can best understand how they can be applied.
These steps are first to identify the problem,
second, to establish a theory of probable cause,
third, to test the theory to determine the cause,
fourth, to establish a plan of action to resolve the problem
and identify potential effects.
Fifth, to implement the solution or escalate as necessary,
six, to verify full system functionality
and if applicable, implement preventative measures,
and seventh, document findings, actions,
outcomes, and lessons learned.
After that, we're going to walk through
all seven steps one more time,
as we work through a real world issue
that you might come across one day
when you're working in the field.
Finally, we'll take a short quiz to see what you learned
during this section of the course and review your answers
to ensure you know why the right answers were right
and the wrong answers were wrong.
So if you're ready, let's get started with our coverage
of the CompTIA seven step troubleshooting methodology
in this section of the course.
