Hello and welcome to Red Hat certified system and the straighter course.
My name is Java bar and I will be your instructor in this course.
I've been teaching online for over two years.
No I have several courses online that include quite a few links courses and some networking courses
as well.
And I've recently started doing some virtualization courses also.
I have over 15 years in Linux and working.
So why are CSA it's one of the most sought after certification in general in I.T. and just like if you
have heard of CCMA for Cisco certifications this certification also stands out because it has retained
its value from the time that it was offered by Redhat till now.
And if you were to talk about strictly Linux then is definitely one off the top model all this the top
sought after our design certification designed by their employers.
If you have the certification you get a higher level off consideration for promotions for job interviews.
It doesn't stand up.
And the fact that I understand is because it's a performance based exam.
Although the trend is most of the exam these days are becoming sort of becoming performance based.
And the days are gone pretty much.
When examinations used certification examinations used to be memorization of things.
But since Linux itself is a subject where it requires you to do tasks all by hand so it makes sense
for the exam to be hands on instead of just something verbal that you memorize and then go ahead and
put it down on a piece of paper on the computer that you know this and thus the employer wants to know
if you actually can do it online.
So it's a certification based exam and it's always changing.
So that's another thing it's not like a certification that we're going to go stale or you just took
the certification today and even 10 years from now is still good.
No it's not because the certification itself is changing.
The technology is changing more and more new things get it added to Red Hat and that's why the certification
has to be redone as well.
Talk about the exam at the number for this exam.
Yes two hundred for our CSA.
It consists of hands on assignments 10 to 15 times that you're given passing a score although it's kind
of vague.
Red Hat kind of keeps it to themselves.
Holiday great things.
But in general people think if you've got one in 10 out of 300 then you should be passing a lot of time
is two and a half hours exam cost as of March of 2018 is 400 USD and the certification validation is
for three years.
After that you have to be certified because in three years I can assure you that there will be new things
added to the operating system itself far ahead.
And some of the things might have changed since the last time you got the certification.
So it makes sense for you to stay up to date on the other operating system.
Now let's talk a little bit about the domains.
Meaning what the exam is going to cover.
It's going to cover a lot of stuff.
They don't want to get you depressed or anything but it has seven different domains and begin to go
briefly over each one of.
First one is understanding and use all the central tools how to access a shell prompt an issue commands
with correct syntax hard use input output redirection use a grab and regular expression access remote
systems using S-sh log in and switch users in multi-user targets archive compress and pack and compressed
files.
So these are some of the tasks and I've read only half of them in the first domain and you've got 7
domains.
So it is quite a bit.
It's very extensive because they are going to cover quite a bit index there.
So they want to make sure that you understand that the second domain is Zerkin domain is operator running
system which will include how to boo how to reboot how to shut down a normal system and hog indirect
causes in order to get access to a system how to locate and system lock files in general and how to
start and stop virtual machines.
Again there are more items in this domain as well.
I just read about half of them to the next one is going to be how to configure local storage.
This is going to include a list create delete partitions or BRG P-T dust's create and remove physical
volumes configure systems to mount file systems at boot kill the next item is going to be create and
configure file system so hard to create mount unmount and use the fat ex-chief for it.
SFX file systems Extel existing logical volumes create and manage access control lists diagnose and
correct file permission problems.
Next one is deploy configure and maintain system.
This will include tasks like a start and stop services and configure services to start automatically
at boot time.
Install Redhat Enterprise Linux systems as Wortzel guests configure systems to use time services update
the kernel package appropriately to ensure a bootable system modify the system bootloader
kit the next one is going to be how to manage users and groups create delete and modify local users
or their accounts change passwords and or just passwords a local user account create delete and modify
local groups and group and bishops configure system to use an existing authentication service for user
user and group information.
Next one is Bendit security.
We've got to learn how to configure firewall settings using firewall dash config firewall ACMD or IP
tables.
We can set enforcing and permissive mode as far as Linux.
We get to the store default file contacts get a diagnose and address routine as the Linux policy violations.
So these are all the domains are loaded the description description of each of the domains.
What are you going to cover.
It's going to be a fairly long course but hang in there and we're going to get a dud.
And by the time we are done with that you're going to feel really confident going into the exam.
I'll make sure that I cover everything that I can think of that could be asked during the test.
The main thing is to get hands on experience so in the next lecture we get to talk about how to get
hands on experience especially if you don't have access to a Linux server.
