Overview
This course gives networking professionals a functional understanding of the BIG-IP DNS system as it is commonly used. The course covers installation, configuration, and management of the BIG-IP DNS system, and includes a combination of lecture, discussion, and hands-on labs.
This course is intended for system and network administrators responsible for installation, setup, configuration, and administration of BIG-IP DNS systems.
Prerequisites
There are no F5-technology-specific prerequisites for this course: However, completing the following before attending would be helpful for students with limited BIG-IP administration and configuration experience:
- Administering BIG-IP instructor-led course
or
- F5 Certified BIG-IP Administrator
IMPORTANT INFORMATION:
F5 has brought out a BIG-IP Admin exam which can be taken before attending the LTM course. Indeed, this test should be taken by anyone wanting to attend any of the F5 specialist classes (DNS, APM, ASM, AFM etc.) if they have not attended the BIG-IP Admin or LTM class.
Although this is not mandatory, F5 would like to stress the importance of anyone attending F5 specialist classes if they have not attended an Admin class or passed the test below with 70% or greater. Obviously, a 201 BIG-IP Administrator exam certification is an instant prerequisite.
- Step 1: get an account on F5 University (https://university.f5.com)
- Step 2: goto: https://wbt.training.f5.com/wbt/go?id=2110
- Take the test. Pass mark is 70%.
- Step 3: take a screen shot as proof of your results.
Please note that if this prerequisite is not met, Arrow ECS reserves the right to refuse entry to the class without refund.
The following web-based courses, although optional, are helpful for any student with limited BIG-IP administration and configuration experience. These courses are available at F5 University (http://university.f5.com):
