ABOUT THE 201-TMOS ADMINISTRATION EXAM.

The 201-TMOS Administration exam is the second exam required to achieve Certified F5 BIG-IP Administrator status. Successful completion of the BIG-IP Administrator exam acknowledges the skills and understanding necessary for day-to-day management of Application Delivery Networks (ADNs).

WHAT IS THE 201-TMOS ADMINISTRATION EXAM BLUEPRINT?

F5 Certified Exam Blueprints list all the objectives an exam has to measure, much like a syllabus for the exam itself. The blueprint provides the detailed breakdown of the skills and knowledge a candidate should have to pass the exam. Blueprints can be used to identify areas for additional study, and are best used in conjunction with the Exam Study Guides.
