The Road to RHCA: In the Trenches

Posted on January 18, 2019 by TazBrownTazBrown

The RHCA is not easy

My friends, the road to the RHCA is by no means a straight line. If I told you it was, I would be lying. In previous blog posts I have written about the bumps and bruises I got along the way to getting certified, and I’m a believer in what does not kill you, makes you stronger. I have always learned the most through failing, and this experience has been no different. The new year brings renewed energy and spirit for me, and an eye toward accomplishing goals. Maybe I will even, dare I say it, make some New Year’s resolutions. Well, you know how those often turn out, so I won’t bother.

These days, I am more about the journey than just sprinting to the finish line. I have learned so much in my successes and my failures, but the journey is what taught the most either way.

Making RHCA a goal

With 2019 still fresh, I find myself reflecting on where I was a year ago, five years ago, and even 10 years ago. I am definitely further along than I have ever been. My life looks like success. And I feel like I’m truly where I have always wanted to be. But my goal for 2018 was to obtain my RHCA, and it did not happen. I won’t make excuses, whether I think they are justified or not. I just didn’t get it done.

I have analyzed my 2018 year, studied what obstacles got in the way, and have a strategy for addressing any that may come up in 2019. Obviously, I don’t have control over everything that happens in my life, but I definitely have the drive to obtain the RHCA, and I will get it in 2019!

I passed the Red Hat Specialist in Virtualization exam on 1/10/2019 and have three more to go before having a full RHCA certification. I used two resources to prepare for the exam: Linux Academy’s EX318 Red Hat Specialist in Virtualization course, and Red Hat’s RH318 course. I’d like to share here about the Linux Academy coursework specifically.
There are different concentrations available in getting to the RHCA. I am aiming for a hybrid of Data Center and Cloud.

The EX318 exam covers these objectives:

  • Installing Red Hat Virtualization Manager
  • Creating datacenters, clusters, pools, and templates in Red Hat Virtualization Manager
  • Installing and configuring Red Hat Virtualization Hypervisors to support Linux, and managing them using Red Hat Virtualization Manager
  • Performing essential management tasksTraining for RHCA

Training for RHCA with Linux Academy

The course and training provided by Linux Academy teaches how to install virtual machines, how to start and stop them, and how to configure automatic migration for them. The course further requires students to learn the theory behind cloud and virtualization, as well as topics like high availability and scalability.

The Linux Academy curriculum also covers creating snapshots, creating virtual machines from snapshots, and importing existing virtual machine images into Red Hat Virtualization Manager. There are lessons about creating internal and external users too, as well as configuring roles, assigning users to those roles, and configuring access using roles. If that wasn’t enough, there are also instructions and labs that let students practice creating virtual machine templates, deploying virtual machines using templates, configuring virtual machines using Cloud-init, creating logical networks, assigning hosts to logical networks, and backing up and restoring the Virtualization Manager.

Linux Academy lets me utilize Red Hat Enterprise Linux 7 cloud servers to practice installing and configuring Red Hat Enterprise Virtualization Manager (RHEVM), along with the hypervisors. It also allowed me to access the customer portal and administration, which are accessible via the web browser. I did have to register RHVM (Red Hat Virtualization Manager) and subscribe to all the entitlements before I could do anything else, like installing RHEL 7 and RHVH (Red Hat Virtual Hypervisors).

Parting words

Compared to some of the other tests, the RH318 exam is relatively easy. But I never underestimate Red Hat exams, and I know I’ve got my work cut out for me. Linux Academy will help get me there. Wish me luck! I will follow up in my next blog, letting you all know the results of my exam and what my next focus will be. I wish all of you continued success, and I hope 2019 proves to be your best year yet!
