How to Prepare For F5-201: TMOS Administration Exam

F5-201

Preparation Guide for F5-201: TMOS Administration Exam

Introduction

An F5 Certified BIG-IP Administrator can manage application delivery networks (ADNs) and perform routine management and troubleshooting of F5 Traffic Management Operating System (TMOS) devices. Two exams are required to achieve the F5-CA certification:

• Exam 101 - Application Delivery Fundamentals
• Exam 201 - TMOS Administration

A F5 Certified BIG-IP Administrator manages preexisting BIG-IP installations and preliminary fault isolations. They must have the ability to make necessary configuration changes and modify BIG-IP objects. They are also responsible for application delivery networks (ADNs) and for conducting routine management and troubleshooting of F5 Traffic Management Operating System (TMOS) devices.

These Certified Experts use TMSH as well as a configuration utility to monitor BIG-IP resources such as virtual servers, pools, pool members, nodes, profiles and monitors. They also create, restore from and manage BIG-IP archives. Certified BIG-IP Administrators are further responsible for checking a resource’s status, availability and statistics, in order to understand how BIG-IP systems are currently processing traffic.

Administrators define the role of BIG-IP systems as a proxy device within an ADN. They set up, license and provision BIG-IP systems. A Certified BIG-IP Administrator uses profiles to control the way BIG-IP systems process traffic through virtual servers. They are also responsible for troubleshooting and determining problems using various diagnostic tools.

Passing this exam shows independence in performing day-to-day operations and basic troubleshooting of TMOS-based devices in various application environments after it has been installed, configured, and implemented. Individuals may choose to complete their certification journey here or move on to pursue the Technical Professional, Technical Specialist, Cloud, or Security Solutions certification tracks.

Introduction to F5-201: TMOS Administration Exam

The qualified candidate is capable of performing day-to-day operations of TMOS-based devices which have already been installed. They are also capable of basic troubleshooting of a TMOS-based device in order to provide full, accurate, and appropriate information to senior engineers and/or F5 Support.

They can do any of the following without assistance:

• Able to access and manage the BIG-IP through multiple paths (management IP, Self IP)
• Perform administrative tasks using the GUI
• Understand the relationship and differentiation between virtual servers, virtual server types, virtual addresses, pools, pool members, nodes, profiles, iRules, and address translation (NAT/SNAT)
