301b - LTM TECHNOLOGY SPECIALISTEXAM BLUEPRINTABOUT THE 301B-LTM SPECIALIST: MAINTAIN & TROUBLESHOOT EXAM.The 301b-LTM Specialist exam is the second exam required to achieve F5Certified Technology Specialist, Local Traffic Manager (F5-CTS, LTM) status.This exam identifies individuals qualified to design, implement, maintain, andtroubleshoot advanced F5 product features to enhance the effectiveness of anApplication Delivery Network. They possess understanding of underlyingprinciples – from SSL-based VPN implementation to symmetric and asymmetricacceleration – and can draw on that insight to integrate Local Traffic Manager(LTM) into existing networks as well as new implementations.WHAT IS THE 301B-LTM SPECIALIST 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 detailedbreakdown of candidate skills and knowledge. Blueprints can be used to identifyadditional study, and are best used in conjunction with the Exam Study Guides.PREREQUISITE:301a-LTM Specialist: Architect, Set-up & DeployCREDENTIAL AWARDED:F5 Certified Technology Specialist, Local Traffic Manager (F5-CTS, LTM)THIS EXAM IS BASED ON V11.2.V1 2013
