The LinuxAcademy and the LinuxFoundation courses were very helpful in my preparation. Would like to specially thank LinuxAcademy for their cloud servers which saved me a lot of time rather than having to keep creating VM's on my system, I could quickly deploy LinuxAcademy servers for practice. Also would like to thank LinuxAcademy and Course Instructor, Terrence Cox for excellent course content and delivery, did the LFCE course and the Ansible, Docker quickstart courses and they were great.
Advice for those giving the exam; read the preparation guide and syllabus carefully and practice and document tasks, use your documentation to repeat and further streamline tasks, document and repeat. Also system documentation is very helpful if you need reference for configuration and parameters, so be familiar with system documentation before you give the exam. If you have a multiple attempt exam, give at least a months time between the first and second attempt to revise and practice.
