Roughly a 7 years ago, my boss offered to me a Red Hat Learning Subscription. Because continuous education belongs to the habits of a good software practitioner, I appreciated this opportunity to deepen my knowledge of Red Hat technologies. At that time I didn’t have an idea about how much fun I was going to have on my journey to become a Red Hat Certified Engineer . Read more, if you want to find out!
In Wikipedia, you can find a great ideas of the Red Hat certification program. To achieve the Red Hat Certified Engineervlevel, you have to pass three exams in total. The certification path starts with the RHCSA exams. After becoming RHCE, you will have to pass one more exams to become RHCE based on your choice to obtain the ultimate RHCA certificate.
Starting off with RHCSA and RHCE
The certification path begins with an entry-level certification – Red Hat Certified System Administrator (RHCSA). In the exam, I had to demonstrate basic Linux administration skills like creating users and groups, managing file system permissions including POSIX access control lists (ACLs), creating cron jobs, basics of SELinux, managing software packages with yum, creating and mounting local file systems, working with LVM, network configuration, mounting NFS and SMB file systems and firewall configuration. I had plenty of time to complete all the exam tasks. Overall, RHCSA didn’t seem too difficult to me.
About two weeks after passing the RHCSA, I took the next exam – the Red Hat Certified Engineer (RHCE) exam. The main focus of this exam was configuration of a caching DNS server (unbound), SMTP nullclient (Postfix), configuration of an iSCSI target and initiator, configuration of Apache web server including HTTPS, running MariaDB, configuration of NFS and SMB servers and basic shell scripting. Based on the experience from the RHCSA exam, I thought that I would have more than enough of time again to complete my tasks and perhaps make myself a coffee, too. How wrong I was! The RHCE exam is loaded with so many tasks that you will be very busy for the entire 3.5 hours. Due to my rather slow and relaxed approach at the beginning of the exam, I was not able to complete all the tasks in time. In the end, I was very happy that I still passed
