So friends, in this particular video, what I want to do is to discuss with you
some exam strategies and just some general tips for taking your RHC examination
.
So with that said, let's just talk about it.
Okay, so the very first tip might seem obvious, but it is very, very important.
You really want to ensure that you are very comfortable with all of the exam
topics as set out in the exam blueprint.
So where can you find this? Well, you can find this directly on the red hat
page.
So if you just search for the RHC exam, go to the red hat documentation and in WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
So if you just search for the RHC exam, go to the red hat documentation and in
the objectives here, pretty much we can see what we should actually understand
in order to be able to take this examination.
We should be comfortable with performing all of the typical RHCSA tasks.
These are things like configuring local storage, creating configure file
systems, that type of thing, and understand that these core components of
answerable things like a loop and answerable.
How do we use variables, different modules, inventories, handling failures,
that type of thing?
All of this is within the actual documentation. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
All of this is within the actual documentation.
Also, be aware that we want to have a good grasp of how to actually use roles
and answerable content collections.
So realistically, what we want to do is to look through all of the information
within this page and you should really honestly assess yourself on just how
comfortable you are with these particular tasks.
Now say for example, you have a little bit of hesitation with respect to roles,
then a good idea would be to revisit the particular skill within this course
that actually deals with that particular subject.
Now eventually, once you give it enough practice and time, you will become WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
Now eventually, once you give it enough practice and time, you will become
comfortable with everything you see within this particular objective blueprint.
Now if we look at the what you need to know tab right here, if you scroll on
down, we can see the actual exam format right here.
So very, very crucial, here's what it says, it says, "During the exam, you will
be provided a list of tasks to accomplish related to the exam objectives, no
surprises there."
Now here's the important part, it says here, in most cases, the task will be
described in the terms of a specific end state that you must achieve.
So this is actually mean, well with respect to the examination, when it comes WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
So this is actually mean, well with respect to the examination, when it comes
to being graded, they're not actually concerned with how you actually got that
particular answer.
Maybe you use a very unique way to solve the problem, but ultimately, if your
solution provides the desired end state, then you will get the points for that
particular question, very, very important.
So quite simply, what I'm saying is that there may be multiple ways to solve a
particular problem, and if you happen to use any one of those valid ways, you
still will get the points for the question.
And this is what I'm trying to emphasize, the exam is going to judge what you WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
And this is what I'm trying to emphasize, the exam is going to judge what you
did, not exactly how you did it.
Now it's very possible that maybe you get to your examination and things become
quite tricky, and you may in fact panic and think, "Hey, I don't know how to do
this particular task."
Now hopefully, this is not going to be you, you will have prepared so well that
all of this will become pretty second nature, but nevertheless, if you do
happen to panic and you can't think what perhaps, maybe what module you should
be using for a particular task,
then a little tip that you should remember is that if you can't remember the WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
then a little tip that you should remember is that if you can't remember the
exact module, what you can potentially do is just rely on the Ansible built-in
command module, and effectively just send the regular Linux CLI commands just
using Ansible.
Now the problem with this is that it's not exactly the most elegant solution,
and recall within the course where you actually identified that this particular
module is not idempotence, this is a very, very important concept within
automation.
So, what I'm seeing here is that the command module might not be able to solve
all of your problems if you run into an issue, but as a fail-safe, just in case WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
all of your problems if you run into an issue, but as a fail-safe, just in case
you don't have any working solution, then this can be a good backup that may
help you get some of those very valuable points that you can use to pass the
examination.
Now let me just highlight how the exam is going to operate. You will have an
Ansible control mode, okay, and then you will have a number of managed devices
which are going to control with Ansible.
So let's just say in another example here, we've got one device, and let's say
we've also got a second device which is going to be managed.
Now effectively, you're going to be graded upon what you actually do on this
particular machine here, the Ansible control mode. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
particular machine here, the Ansible control mode.
Now that might sound a little bit strange because ultimately you're managing
these two devices here, but realistically, these devices are actually going to
be deleted and effectively destroyed.
So here's what the implication is, what I'm saying is you can't just manually
log into these devices and just configure the desired end state that you wish
to achieve if you can't figure out how to do it with an Ansible playbook.
Say for example, the exam tells you to create a file called nugget.txt on both
managed devices.
What you can't do is just manually SSH in and type the command touch nugget.txt WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
What you can't do is just manually SSH in and type the command touch nugget.txt
and then log into the next one and do touch nugget.txt.
That is not going to work because like I say, at the end of the examination,
effectively these two machines get destroyed and everything that you have
manually created on them is also going to be lost.
What will then happen is that the examiners are effectively going to spin up
the same type of environments, but with fresh machines and they're just going
to use the playbooks that you crafted on the control node to attempt to push WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
to use the playbooks that you crafted on the control node to attempt to push
out those changes to those devices and if those devices have the desired end
state,
then your Ansible control node did what it was supposed to do.
So really what I'm saying here is all of the desired end state really has to be
controlled via your Ansible playbooks.
So like I say, if you do get stuck, you can use the Ansible command module
within a playbook.
Just don't try to take the commands manually by logging in to the managed
devices directly.
That will get you no points and certainly will not work at all.
Now very, very important point to note here is that with respect to the WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
Now very, very important point to note here is that with respect to the
examination, you're not going to have internet access provided during the exam.
Also, you're not going to be able to bring any hard copy or electronic
documentation into the exam, so no little cheat sheets for yourself, but what
you can use and what you should use is that you're not going to have internet
access provided during the exam.
So you can bring in your own custom electronic documentation with all your
little cheat sheets.
You can still make use of things like say for example Ansible Doc.
And in fact, this is a type of thing that you really should be relying on in
the examination.
This is going to cut down a lot of your, what could potentially be, waste the
time so that you can ultimately make the best use of your time. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
time so that you can ultimately make the best use of your time.
This is a timed examination after all.
Now another point that you're going to do is you're going to be able to make
the best use of your time.
This is a timed examination after all.
Now another point I want to highlight here, if you look at the actual
objectives here and we go down, what it says in the objectives is that you
should be able to run playbooks with the automation content navigator.
This is Ansible Navigator.
Now because of this, we certainly covered this as part of the course.
This is something that all RHC certified engineers should understand after all, WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
This is something that all RHC certified engineers should understand after all,
but just understand that in the actual examination, you don't actually have to
run your playbooks with the Ansible Navigator.
You can effectively choose to run them if you so wish, but in my opinion, this
just adds another level of complexity that you shouldn't have to worry about in
a timed examination.
So whilst I'm not going to say to you, absolutely do not use Ansible Navigator,
just understand that you don't have to use it.
And at least in my recommendation, I would personally avoid it for the exam
itself.
For me, when it comes to actually run a playbook, I would just rather use the WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
For me, when it comes to actually run a playbook, I would just rather use the
Ansible High from Playbook command directly on its own.
Now one final point, I just want to impress upon you.
Make sure you really, really, really read all the information provided very
carefully.
Don't go making assumptions and then begin configuring your tasks based on
those assumptions.
That is how you effectively lose points and you might end up feeling the
examination.
If you read the questions carefully and you tailor your solution towards those
objectives, then by all means, if you are well prepared, you will be in a great
place to pass the examination. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
place to pass the examination.
