Welcome to this course
on the CompTIA Linux+ Certification.
This certification is designed for IT professionals
who need to configure, operate, maintain,
and troubleshoot servers and workstations
that are running the Linux operating system.
After all,
Linux is the dominant server operating system in the world
and it hosts most of the web servers on the internet
and it became the backbone of cloud-based services
all over the globe.
For this reason,
Linux+ is an essential part of your education
and it's going to provide you
with a great foundation of knowledge
to build upon throughout your career
whether that takes you into the world of server management
or into the world of cybersecurity
in the future as well.
This certification is designed for beginners
who have less than one year of IT operations
or administration experience,
or for those students who have already completed
the A+, Network+, and Security+ exams.
On the Linux+ exam,
knowledge from these other exams
is considered assumed knowledge
so we're not going to be reteaching all that content
in this course.
Instead,
we're going to be building upon that foundational knowledge
of hardware, software,
networks, and security throughout this course,
but don't worry,
we're also going to review any area specific to the Linux+ exam
that you may need to know for this exam
inside of this course as well.
Now, if you haven't done your CompTIA+, Network+,
or Security+ exams yet,
that's okay.
We're still going to get you through preparing
for the entire Linux+ exam
without any issues,
but there may be some parts
where you feel like don't go into enough depth
and if that's the case,
I ask that you go back and find a good A+, Network+,
or Security+ textbook or video course
and review those topic areas
that are specific to the areas you're getting confused on.
The CompTIA Linux+ exam does consist of four domains
or areas of knowledge
that you're going to receive questions on
when you sit for your certification exam:
domain 1 is System Management,
and it makes up 32% of your exam questions.
This domain is focused on configuring kernel modules,
network parameters,
software and services,
managing files and directories,
and configuring storage devices
on your Linux systems properly.
Domain 2 is Security,
and it makes up 21% of your exam questions.
This domain is focused on your ability
to understand the best practices
for permissions and authentication,
firewalls, and file management
on your Linux servers.
Domain 3 is Scripting, Containers, and Automation,
and it makes up 19% of your exam questions.
This domain is focused on your ability
to execute basic batch scripts,
conduct version control using get,
and your understanding of cloud
and virtualization technologies
and how to implement orchestration
in your systems and networks.
Domain 4 is Troubleshooting,
and it makes up 28% of your exam questions.
This domain is focused on your ability
to analyze system properties and processes
and troubleshoot users, applications,
and hardware issues
that may come up when you're using Linux systems.
Each of these four domains contain several objectives,
they'll make up all the topics
that you're going to learn about in this course.
Note though,
we're not going to be teaching these domains
or their objectives
in the order presented
in the CompTIA official exam objectives
which you can download from lesson 2 of this course,
but we are going to cover each and every one of them
throughout our time together in this course.
This is because the order presented
in the exam objectives list
isn't really appropriate to teach
in that particular order.
So I've created a better order
to teach you all of the material
so you can learn it easier.
At the beginning of each section of the course,
I'm going to tell you which objectives
we're going to be covering
in that specific section of the course,
and I've also titled each lesson
with the appropriate objective number
in parentheses after its name
for easy reference if you need to go back
and study a single objective
as you do your last minute review for your exam.
On test day,
when you sit down to take the exam,
you're going to get a mixture of questions
from across all four domains
and all of their objectives.
Also, some questions on the exam
may combine objectives from different domains
into a single question
to test your knowledge more in depth.
Speaking of the exam,
when you sit down
to take the CompTIA Linux+ certification exam
at the testing center or online
using the web proctoring service,
you're going to be getting 90 minutes
to answer up to 90 questions.
For the most part,
you're going to be answering multiple choice questions
but you'll also have a few multiple select questions
where you pick two or three correct answers
for a single question
and a few performance-based questions too.
These PBQs or simulations,
as most students like to call them,
require you to perform some kind of job function
in a simulated environment.
For example,
the exam might ask you to create a new user account
on a Linux system
or to change the permissions on a file or folder,
then you're going to use the mouse and keyboard
to perform those actions.
Don't worry too much
about the simulations just yet though,
I'm going to make sure you are well prepared for them
before you sit down for the real certification exam.
Now as far as the number of questions
you're going to get on exam day,
you might have noticed that I said up to 90 questions.
Well, in truth,
you're going to get somewhere between 70 and 90 questions.
If you get more simulations,
then you're going to have less multiple choice,
and vice versa.
Now, most candidates are going to see
between three and five simulations on the exam
and about 80 multiple choice questions
come test day.
Also, when you take the exam,
the simulations are going to be
the first three to five questions that you receive
on the exam,
and the rest of the exam is going to be done
through multiple choice or multiple select questions.
To pass the Linux+ exam,
you have to score at least a 720 out of 900 possible points
on the exam.
This equates to roughly an 80% or higher
on the certification.
Now to take the exam,
you do have to pay an exam fee
to cover the cost of testing,
and you do that by buying an exam voucher.
You can do this by going to store.comptia.org
and buying it from their web store.
In the CompTIA Store,
you're going to see the vouchers cost
around $350 in the United States,
but this does vary
depending on where you live in the world.
If you'd like to save a little bit of money
on your exam voucher though,
you can visit diontraining.com/vouchers
to purchase your exam voucher directly from us.
Because we are a certified Platinum level
CompTIA Delivery Partner
and we help tens of thousands of students
pass their CompTIA exams every year,
they give us a discount rate for these exam vouchers
and we pass the savings onto our students.
So if you take that one extra step
of going to diontraining.com/vouchers
and you purchase your exam voucher from us,
you're going to save about 10% or so
off the regular CompTIA price
and you'll also receive access
to our searchable video library
that you can use for your last minute studies
before test day.
Now, before we begin studying for the exam,
I want to give you my four tips for success
in this course
that are going to help you better study for your exam.
First, we provide closed captions
for every video in this course
that's caption by a real human
to ensure a higher level of accuracy for you.
Many of my students
who speak English as their second language
really love having these captions available
so they can read along while I'm teaching.
To turn them on,
simply click the CC button
in the bottom of the video player.
There's also a transcript available here,
with each video,
that you can access and search
for specific keywords or phrases
within that video too if you need to.
Also, when it comes to speaking,
some students say that I speak too fast
and others say I speak too slow.
Either way though,
you can control the speed of instruction
by adjusting my playback speed.
If I happen to be talking too fast for you,
you can slow me down by taking me down to .75 or 75%.
If I'm talking too slowly for you,
you can speed me up by putting me at 1.5x or 150%.
Either way, faster or slower,
the choice is yours
so you can learn most efficiently.
Next, I want to point out
that all the information I'm going to teach you
in this course
is also available as a downloadable study guide
in PDF format.
You can download this in lesson 2 of the course.
Here, you can download it,
print it out, and then use it and take notes,
or highlight and circle important information
as we go through the course together.
This PDF is a great tool for offline studying
before you take your final exam as well
because you'll have all of your notes in one place.
Finally,
I want you to know that we have a Facebook group
set up specifically to help you succeed with this
and your other certification exams.
If you have any questions or get stuck on something,
or you just want to talk to other students
who are studying for the same exam,
you can do all of that
by going to facebook.com/groups/diontraining.
If you join the group on Facebook,
we have people ready to answer any questions you might have
as well as having other students helping you as well.
Currently, we have over 35,000 students in this group,
so if you have a question about the Linux+ exam
or any of the course content,
I guarantee somebody there has the answer for you
really quickly.
Now with all the basics out of the way,
let's get started learning all about Linux
in our CompTIA Linux+ Certification Course.
