Important Note : 

Objectives of RHCSA exam have been updated by RedHat with new topics related to Containers and simple shell scripts.

People who purchased RHCSA exam on 1st October and afterwards will have to cover these additional topics to pass the exam.

These recently added Objectives to this Exam have been updated in this Course!

Course Description

The Main Objective of this course is to help you to succeed at First Attempt!!! and enable you perform different tasks independently at your Job.

In this course , All Objectives of RHEL-8 based RHCSA exam are explained with the help of different practical tasks( Which mimic real exam tasks) on each objective covering complete syllabus as mentioned on Red Hat official Website.

Tasks are explained through video lectures explaining tasks in details but you must know theory part which is prerequisite for this course.

After completing this course , You will be confident enough to pass the exam at first attempt but you must practice all tasks before taking the exam.

Without practice, It is not possible to pass exam ! but there is nothing to worry too much, if you understood all objectives and practiced all tasks, You will pass the exam at first attempt.

You will find tasks on exam from these Objectives only!!

Also PDF document is uploaded for each section at end of each section briefing all tasks and different steps to perform each task. This will help you to practice tasks after you complete the section.  You don't need to watch the lectures again and again in case you forget something while practicing.

LAB SETUP

For LAB Setup, Two VM's are setup using Oracle VirtualBox Manager, One VM (named IPA Server) just to provide required services e.g. DNS,LDAP,NTP,NFS and SAMBA to other machine and you don't need to know how to configure these services for RHCSA Exam because this is not part of RHCSA Objectives.

Other Linux VM (named System) will be used to practice all Objectives of RHCSA Exam.

IPA Server machine is preconfigured to provide all required services and you will be able to download .ova file for this VM to import the machine in Oracle Virtual Box in 5-10 minutes.

You don't need to configure this Machine and only in few minutes you will have machine up and running.

However one extra section is included to describe how to configure IPA Server machine to provide different services needed to practice RHCSA Objectives. You can install & configure IPA Sever machine yourself if you want to do it yourself.

Last but not least ,I would expect positive or negative ratings/reviews depending on your experience ,expectations and outcome. Both positive and negative reviews are most Welcome.  This will help me to produce better content in future!

Many Thanks,

Prince Bajaj

Description 
My training consist in 10 lessons. The duration of each one is between 60 and 90 minutes. 

This is the ULTIMATE RHCSA Preparation Course. 30% of all first time RHCSA fail to pass the test on their first try. Be part of the 70% who pass RHCSA on their first try. 

Classroom training cost anywhere from 3500 to 7500 for a week worth of training. Who has that type of money, or time, take advantage of the discount price of this exam.

This is an engaging self-paced video course that provides learners with real world examples and how they may be tested in the RHCSA course. 

  • ALL THE VIDEOS ARE FROM MY PREVIOUS TRAINING COURSE, WHERE AT SOME POINTS OF THE VIDEOS YOU WILL SEE THAT I ASK FOR QUESTIONS. 

  • THE VIDEOS HAS NOT ANY KIND OF EDITION 

  • THE VIDEOS QUALITY IS GOOD 

  • I DO NOT EXPLAIN HOW TO CREATE THE SERVER NOR THE CLIENT VIRTUAL MACHINE TO PRACTICE ALL THE OBJECTIVES - BUT I WILL UPDATE THE COURSE WITH THIS EXPLANATION.

  • NO PRACTICE EXAM PROVIDED... But I will update the course with one practice exam.


I GUARANTEE YOU
if you practice every objective as I show on the videos, you will absolutely ACE the real exam. I focus more in the practice and less on the theory. Because the key to pass the exam at first try is "practice and more practice". 

What is different about my training from the rest of the courses? 
The course I give is based on the key points to pass the EX200 (RHCSA) exam on your first try. It is worth clarifying that I do not waste time into basic topics such as: moving through the file system, creating directories and files, as these points are practiced during of my training.  
I expose each goal by the easiest way in which you can memorize how to do it, it is worth clarifying that there are several ways to achieve the same result. 

During my training, I mention several tips that will help you during the exam.  

Guaranteed to pass the exam? 
No one can give you the guarantee that after take the training, you will pass the exam. Since the key to everything is practice. Even official partner courses do not guarantee that you pass the exam. 

Books or documentation to use  
On the internet you can find much documentation of each topic related to the exam, it is only know how to search and put it into practice.  
Example: How to extend a logical volume. If this same question puts it on the internet, you will get many answers on how to achieve it. Now you need to know how to apply it to your system. 

What distribution should you use in training? 
You can use any distribution, but I recommend using a Red Hat based distribution (Fedora, CentOS, RHEL) Preferably using RHEL, you can enroll in developers at redhat and get a free copy of the software, or you can go and register on redhat where you can have updates for 30 days. 

In my course I use Red Hat Enterprise Linux 7.3

How to use this subscription of 30 days, on the same page explain you how to do it.

There are two exams here for you to practice the RHCSA version 8. Exam 1 is extremely thorough in providing the answers to the questions. Not only that, I show you how to do the setup for your home lab to simulate what a real RHCSA exam is like. For example, setting up an NFS server yourself is not required for the actual exam, but you do have to know how connect an NFS client to an NFS server, so these exams are very practical. You will create two nodes (similar to the exam), so you don't have to guess how a task might work. You'll actually be doing all the tasks and seeing the results :)

Also, Exam 1 covers the new October 2020 update for the exam providing 3 Tasks for podman containers.

Exam 2 offers hints for each task and each task number is directly related to the same task from Exam1 (with some added curveballs). Exam 2 does not provide the answers.  I do this not only to encourage participation and for students to ask questions, but also as a way for you to learn the material.

Happy practicing!

Please be aware, I am not an official Red Hat instructor, nor am I affiliated with the Red Hat team or organization in any way. Please use these exams for your own practice.
