EX442 Practice Exam Lab

This hands-on lab is built around the objectives identified by Red Hat for the `Red Hat Certified Specialist in Performance Tuning (EX442)` exam. The EX442 exam is a practical, scenario-based exam. This lab is not an exact copy of the exam; it is designed to provide possible tasks and situations that you might encounter when taking the exam. The lab will have a 4-hour time limit, matching the actual `EX442` exam duration, and will serve as a summary of the some of the lessons and materials covered during this course. Good luck with your studies! *This course is not approved or sponsored by Red Hat.*
