About the course

The course is built to help you prepare to take the Red Hat Certified Specialist in Performance Tuning (EX442) exam. The course is based on Red Hat Enterprise Linux 8 and the lessons will focus on various standard tools used to analyze the performance of a Red Hat Enterprise Linux system as well as build and validate your knowledge of these tools so you can use them to update and tune the performance of a Red Hat Enterprise Linux system as well as the applications hosted on it.

Completing and passing the EX442 exam will provide you the Red Hat Certified Specialist in Performance Tuning certification. Additionally, this certification can be applied towards gaining the Red Hat Certified Architect (RHCA®) certification if that is a path you would like to follow.

This course is not approved or sponsored by Red Hat.
