Red Hat Certified System Administrator (RHCSA) exam ex200
 

Hi, I'm planning to do the Red Hat System Administrator exam in some time.
To do studying and exercise examples I found some pdf. I found the pdf here: https://access.redhat.com/documentat...uide-en-US.pdf which looks like an official resource.

Now I just check the table of content I see some many chapters (ptp, ntp etc).
If I check the page wich describes the exam I see less things to know than there are in the pdf:

https://www.redhat.com/en/services/t...tor-rhcsa-exam

Understand and use essential tools

Access a shell prompt and issue commands with correct syntax
Use input-output redirection (>, >>, |, 2>, etc.)
Use grep and regular expressions to analyze text
Access remote systems using ssh
Log in and switch users in multiuser targets
Archive, compress, unpack, and uncompress files using tar, star, gzip, and bzip2
Create and edit text files
Create, delete, copy, and move files and directories
Create hard and soft links
List, set, and change standard ugo/rwx permissions
Locate, read, and use system documentation including man, info, and files in /usr/share/doc

Note: Red Hat may use applications during the exam that are not included in Red Hat Enterprise Linux for the purpose of evaluating candidate's abilities to meet this objective.

Operate running systems

Boot, reboot, and shut down a system normally
Boot systems into different targets manually
Interrupt the boot process in order to gain access to a system
Identify CPU/memory intensive processes, adjust process priority with renice, and kill processes
Locate and interpret system log files and journals
Access a virtual machine's console
Start and stop virtual machines
Start, stop, and check the status of network services
Securely transfer files between systems

Configure local storage

List, create, delete partitions on MBR and GPT disks
Create and remove physical volumes, assign physical volumes to volume groups, and create and delete logical volumes
...


So my question is: Do I have to learn (+ exercise) the stuff which is described on the ex200-red-hat-certified-system-administrator-rhcsa-exam URL or can it be more abroad? (stuff from the pdf like the ntp stuff for example?)

You will need to learn everything that is in the Red_Hat_Enterprise_Linux-7-System_Administrators_Guide-en-US.pdf.

If you can you really should get the RHCSA Study Guide book to help you study.
There are 2 Exams, EX 200 and EX 300 and they may have changed that since RH became 7:-

If you already have the skills from running Linux for a long length of time you can save the money that you would have to pay to take the exams and still get hired without the certification. And, in some cases a new employer will give you favor and pay for you to take the exams.

Good luck and Best Regards

Vendors are constantly producing new products to sell you, and they'll always try to "up-sell" their existing customers with one new certification after another. :rolleyes:

The one thing that I think is good about certifications is ... the study materials. Especially if you come in knowing very little about Linux, and perhaps about (say ...) "systems administration" in general, these guides are written by professional education designers and so they will provide you with a great introduction. (And, most of the material actually isn't that release-specific.)

If you want to go that route, study the materials that are provided for several different Linux distros, not just (any) one. Notice how they are both the same and different.

Definitely set up virtual machines, e.g. using VirtualBox®, obtain a copy of the distro in question, and do the things that you are studying. Set up scenarios of your own devising and practice them. Look for, not only the distro-specific detail, but the proverbial "big picture."

Whether you want to "get a piece of paper to hang on your wall and throw darts at" is entirely up to you.
