Now I really am able to introduce you now to the Linux+ exam. When we go
through and take a look at Linux+, originally CompTIA had teamed up and were
working with the Linux Professional Institute. The Linux Professional Institute
had two separate exams to be certified as LPIC‑1, and it was these exams that
were also used by CompTIA. However, in the last release of the exam,
XKO‑004, CompTIA released their own independent single exam.
Now this was really quite critical because they wanted the
certification to go in a different path.
So we're still keeping with the idea that we were working with more
than one distribution, and they work with CentOS, Ubuntu, and SUSE
looking at topics such as system management,
security, automation, and troubleshooting.
But keeping as an independent exam themselves,
then they don't just have to issue multiple choice
questions. They can start adding in a little bit of
performance or practical element to it.
We're also seeing this summer is the launch of the new exam,
XKO‑005, and this includes a new focus on the DevOps toolset.
When we start looking in more detail at the content of the different courses,
and these courses are available to you now on Pluralsight, we have the System
Management course. And with this, we look at files, archiving, our file
systems, our different types of file systems,
including those stored on RAID and NAS devices,
management of our services the, Linux boot process,
network configuration, as well as software management.
As we then start moving into the automation, this really has a lot of really,
really new and valuable content.
So we're looking at scripting, containers, and automation, and this is then
going to include using Git, the version control system,
creating shell scripts, but then working with computer management systems,
configuration management systems such as Ansible, Puppet,
SaltStack, and Chef.
Now these are also part of what's called Infrastructure as Code,
but that includes then provisioning of systems, and we can look at
things such as Vagrant, as well as Terraform for provisioning your
virtual machines. Along with this, we also throw in a little bit
of Docker and Kubernetes,
so we're really going to make sure that you are really
well prepared for the modern environment.
Most of these products are installable on Linux, and we're going to make
sure that you don't just know Linux, but you're able to work with the
tools that are used in conjunction with Linux.
Moving on to the next course,
we can take a look at managing security, and this then
includes managing the basic file permissions,
special permissions, and access control lists; a mandatory access control
list, which includes SELinux and AppArmor; managing Secure Shell, or SSH,
keys and certificate servers; privilege escalation, so looking at how we can
use sudo and configure sudo, as well as other methods such as the su command;
managing our local users and groups; setting up web servers to be able to use
HTTPS and looking at OpenSSL certificate servers; OpenLDAP, our directory
service; as well as they're looking at firewalls, and firewalls being things
like our UFW on Ubuntu and firewalld on our Red Hat‑based systems.
The troubleshooting course, well, of course, looks at troubleshooting,
but it's looking at troubleshooting your networks,
troubleshooting memory and CPU bottlenecks, taking a look at storage and some
of the issues that we might have with our storage devices,
problems with our users and user access, and we can look at other things such as
then making sure that our users don't take up all of our disk storage by
implementing quotas before we take a look at some of the troubleshooting tools
that we can use that are built into systemd.
So that then gives you an idea of what you're going to get in the exam.
And of course,
in this very short module, we've introduced to you the Pluralsight CompTIA
Linux+ certification, so CompTIA themselves, Linux+, DevOps, or at least
the DevOps toolsets that we are looking at now included in our CompTIA
Linux+ exam. Coming up next though, we're going to be taking a look at studying for and taking the exam.
