Just updated Just updated my almost outdated EX342 Red Hat Certified Specialist in Linux Diagnostics and Troubleshooting certification…

Just updated my 11 years old EX442 Red Hat Certified Specialist in Linux Performance Tuning certification. First I did it on RHEL 5 in 2009 when I finished my RHCA certification. Now updated it on RHEL 8. It is still one of the hardest exams I ever passed.

Just updated my EX280 Red Hat Certified Specialist in OpenShift Administration certification with OCP 4.2. My previous EX280 certification was done five years ago on OpenShift 2.1.
