>> Hello, Cybrarians.
00:00
>> Welcome to the Linux plus Course here at Cybrary.
00:00
>> I'm your instructor, Rob Goelz.
00:00
In today's lesson, we're going to talk
00:00
about why you might want to take this course.
00:00
The CompTIA Linux plus exam and certification,
00:00
the prerequisites and target audience
00:00
for this particular course.
00:00
We'll discuss the structure of the course.
00:00
I'll introduce myself a little bit and finally,
00:00
you'll determine whether or not you're ready to take
00:00
the course by taking an exam
00:00
pre-assessment at the end of the lesson.
00:00
Why should you take the course?
00:00
This course will put you on the path to
00:00
becoming a Linux systems administrator.
00:00
The content in the course focuses on
00:00
foundational Linux system administration
00:00
as well as modern and emerging concepts.
00:00
We'll talk about containers,
00:00
version control with Git and infrastructure as code.
00:00
All of the material that is on
00:00
the Linux plus exam blueprint is covered in
00:00
the course and we will go through
00:00
this content using lecture and video demonstrations.
00:00
This will make you a more well-versed systems
00:00
administrator and give you
00:00
a better understanding of Linux in general.
00:00
The Linux XK0-004 exam
00:00
is a 90 minute test with a maximum of 90 questions.
00:00
That means that there may be less than 90 questions,
00:00
but there will never be more.
00:00
These questions are multiple choice
00:00
and performance-based questions,
00:00
which means that they may be drag and
00:00
drop or fill in the blanks type of questions.
00:00
The passing score for this exam is 720 out of 900 points.
00:00
Prerequisites, strictly speaking,
00:00
and according to CompTIA's Linux plus exam blueprint,
00:00
the candidate taking this exam should have
00:00
nine to 12 months of hands-on experience.
00:00
That doesn't mean that you have the support
00:00
Linux professionally.
00:00
You can be a hobbyist,
00:00
but experience running any Linux OS
00:00
is going to be important here.
00:00
For the purposes of this course,
00:00
we're going to be using CentOS and Ubuntu as
00:00
R2 Linux distributions for doing the demonstrations.
00:00
However, all that being said,
00:00
you should have an understanding of a lot
00:00
of the material that is covered in
00:00
the CompTIA plus a Network Plus
00:00
Certifications because a lot of the content
00:00
that we're going to cover here is going to overlap or
00:00
expand upon the content that is
00:00
covered for those certifications.
00:00
The target audience, as I said,
00:00
this is for professionals with
00:00
six to nine months of experience in Linux
00:00
so generally that means a Linux systems administrator
00:00
who doesn't hold the certification.
00:00
We could also be looking at
00:00
existing Linux plus holders who are looking to refresh
00:00
their skills or a systems administrator
00:00
with one to two years of experience,
00:00
systems administrators doing
00:00
Windows systems administration for example.
00:00
We'd also love to have
00:00
security professionals who are looking to
00:00
specialize and get more well-versed in Linux.
00:00
As I said before,
00:00
Linux enthusiasts or hobbyists are welcome as well.
00:00
Let's go a little bit over the course outline here.
00:00
Our domain one is going to
00:00
cover hardware and system configuration.
00:00
That is 21 percent of the entire content that is
00:00
covered on the exam and that's going to
00:00
take us from Modules 1 through 6.
00:00
In domain two, we're going to talk about
00:00
systems operations and maintenance,
00:00
26 percent of the content on
00:00
the exam and Module 7 through 14.
00:00
From there, we're going to get into security in domain 3,
00:00
that's Modules 15 through 20,
00:00
and that is 19 percent of the exam.
00:00
Then domains 4 and 5,
00:00
more or less expand upon,
00:00
will be covered in the first three domains and they cover
00:00
20 percent and 14 percent of
00:00
the content on the exam respectively.
00:00
It's going to take us for Module 21 all the
00:00
way through the end to Module 27.
00:00
There are quite a bit of sub-objectives on this exam,
00:00
and I won't call all of these as we go through
00:00
here but a couple of these are important
00:00
are working with kernel modules,
00:00
working with and configuring storage and
00:00
networking, setting time zones,
00:00
controlling services with systemd and
00:00
SysVinit and learning how devices operate in Linux.
00:00
As we move on throughout the course,
00:00
where else can learn a lot about
00:00
file and directory permissions.
00:00
We're going to learn about things
00:00
like SELinux and AppArmor.
00:00
We're going to identify and
00:00
configure security best practices.
00:00
We're going to work a little bit with Linux firewalls.
00:00
You're going to learn how to do backups and compression.
00:00
Beyond that we are also going to work with
00:00
common user application and hardware issues.
00:00
Then as I said towards the end of this course,
00:00
we're going to learn a lot about
00:00
BASH scripting working with
00:00
Git an orchestration concepts and processes.
00:00
As you go through this course,
00:00
we've also provided some content and resources here,
00:00
course materials that you can use
00:00
to assist you in your studies.
00:00
There's a study guide, a syllabus,
00:00
glossary, and we'll also provide references to you.
00:00
These can be found on the resources tab
00:00
of the course in Cybrary.
00:00
A little bit about myself.
00:00
My name is Rob Goelz.
00:00
I am a systems engineer.
00:00
I've been in IT for 17 years.
00:00
I hold a Linux Plus Certification.
00:00
I'm also Red Hat LPIC and SUSE certified.
00:00
You can find me on LinkedIn
00:00
and my email address is below.
00:00
I am coffee addict and you
00:00
can see there are a bunch of pour-over be made.
00:00
A few years ago I ran the tough mater
00:00
and I'm not sure that that was the greatest idea,
00:00
but it was a lot of fun.
00:00
I support the Pittsburgh Penguins,
00:00
which of course is appropriate because
00:00
Lennox as mascot pucks is a penguin.
00:00
Let's go through these assessment questions.
00:00
What command would you use to
00:00
list the contents of a directory?
00:00
The answer here is ls, the list command.
00:00
Question 2, which command would you
00:00
use to determine the current directory that you're in?
00:00
The answer here is pwd,
00:00
the present working directory.
00:00
Question 3, the blank is the main component of
00:00
the Linux operating system and is the interface
00:00
between computer hardware and processes.
00:00
This of course, is the kernel.
00:00
Which of the following are package managers?
00:00
There are two correct answers to this question.
00:00
APT and YUM are
00:00
the package managers in question after apt,
00:00
Git is what we're going to use when we work
00:00
with a Ubuntu and YUM is what is
00:00
used for CentOS and RPM based distributions.
00:00
What are the most common methods
00:00
to connect to a Linux server?
00:00
Again, this is a multiple answers here.
00:00
The answers are SSH and VNC.
00:00
Which commands can be used to run
00:00
with elevated privileges in Linux.
00:00
The answer here are sudo and the su dash command.
00:00
Sudo allows you to temporarily
00:00
escalate privileges under normal user account.
00:00
Whereas su dash allows you to become the root user.
00:00
Question 7, which of the following commands is most
00:00
likely to be used to verify network connectivity?
00:00
The answer to this question is
00:00
the ping command. Question 8.
00:00
Which of the following commands can be used to
00:00
display the current time on a Linux system.
00:00
The answer to this question is date, the date command.
00:00
Which of the following file systems are known as
00:00
virtual or pseudo file systems?
00:00
Multiple answers here as well, /sys,
00:00
/dev and /proc are all virtual file systems.
00:00
Question 10, final question here.
00:00
Which of the following commands can be used
00:00
for name resolution and Linux?
00:00
Here again we have three answers dig, host,
00:00
and nslookup can all be
00:00
used for name resolution in Linux.
00:00
Let's look at how you did.
00:00
If you correctly answered 10 out of 10 questions,
00:00
you're going to do great in the course.
00:00
No worries. Now if you've got somewhere between
00:00
five and nine questions, correct congratulations.
00:00
Make sure as you go through the course
00:00
to watch lessons as many times as
00:00
necessary to make sure that you're
00:00
staying on top of the content.
00:00
However, if you've got less than five questions correct,
00:00
please take the cybrary course,
00:00
fundamental Linux administration before this course.
00:00
It's a great course and it'll get you
00:00
set up for success as we go forward.
00:00
With that being said in this lesson,
00:00
we talked about how the course will benefit you.
00:00
We had an overview of
00:00
the CompTIA Linux Plus Certification.
00:00
We cover the prerequisites and
00:00
target audience for this course.
00:00
We discussed the structure of this course.
00:00
We met the instructor
00:00
myself and we took a course assessment.
00:00
Thank you so much for being here and I look
00:00
forward to seeing you in the next lesson.
