F5-Networks 301b Exam (BIG-IP Local Traffic Manager (LTM) Specialist : Maintain & Troubleshoot) Detailed Information
301b - BIG-IP Local Traffic Manager (LTM) Specialist Exam: Maintain & Troubleshoot
Exam Summary:
This exam identifies individuals qualified to design, implement, maintain, and troubleshoot advanced F5 product features to enhance the effectiveness of an Application Delivery Network. They possess understanding of underlying principles – from SSL-based VPN implementation to symmetric and asymmetric acceleration – and can draw on that insight to integrate Local Traffic Manager (LTM) into existing networks as well as new implementations.
This is exam 2 of 2. Candidates must have passed the 301a exam in order to be eligible for the
301b exam.
Minimally Qualified Candidate for the
301b Exam:
The minimally qualified candidate (MQC) for the BIG-IP LTM Specialist candidate is able to describe and explain how the applications work through OSI layer 7. The MQC is able to design, implement, maintain, optimize, and troubleshoot advanced LTM product features to enhance the effectiveness of an Application Delivery Network. The MQC understands the underlying principles of the BIG-IP LTM and can integrate specific LTM technologies with other platforms and products.
The MQC Can Do the Following and More Without Assistance:
Create an LTM configuration/design to deliver applications in a scalable, highly available and redundant environment to meet customer specifications.
Create application specific monitors.
Select and configure the most appropriate LB method based upon the application requirements and server capabilities.
Determine when to SNAT and when not to SNAT.
