How to Prepare For F5-201: TMOS Administration Exam
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.

NEW QUESTION 75
How should a BIG-IP Administrator control the amount of traffic that a newly enabled pool member receives.
- A. set the Priority Group Activation
- B. set a Health Monitor
- C. set a Connection Limit
- D. set the Slow Ramp Time
Answer: D
Explanation:
Explanation
Slow Ramp Time
Specifies the duration during which the system sends less traffic to a newly-enabled pool member. The amount of traffic is based on the ratio of how long the pool member has been available compared to the slow ramp time, in seconds. Once the pool member has been online for a time greater than the slow ramp time, the pool member receives a full proportion of the incoming traffic. Slow ramp time is particularly useful for the least connections load balancing mode.
Setting this to a nonzero value can cause unexpected Priority Group behavior, such as load balancing to a low-priority member even with enough high-priority servers.

- B. The first time the systems are synchronized the receiving system will be assigned the same self-IP addresses as the source system.
- C. When the administrator attempts to access the configuration utility using the host name, they will always connect to the active system.
- D. Host names do not matter in redundant pair communication.
