F5 Getting Started Series now on 11.x

Good news from F5! F5 refreshed his WBTs on F5 University using 11.x code. They called this the “F5 Getting Started Series” and each section has interactive questions to do a check up of your knowledge. This Series covers the following products:

  • BIG-IP LTM
  • BIG-IP GTM
  • BIG-IP APM
  • BIG-IP ASM

Just click on the product and that will open automatic a new window.

As before you can have hands-on on a virtual lab for 11.x code with the following topology. After you login on F5 University click on F5 Training Lab menu and get you Lab guide. Unfortunately you can´t play HA features on this lab but you can try the F5 BIG-IP LTM virtual edition (request a trial licence 90 days) for your own lab.

I took the F5 101v2-Application Delivery Fundamentals beta exam

I was a guinea pig for F5 101v2 beta and i did it well i guess. After answer 140 questions in 150 minutes + extension of 30 minutes (not english native, but was not necessary) the hard part of this was review all my answers, yes again 140! I didn´t find this hard as mention by other guys who did the 101v1. After you submit the exam you can comment the questions (no chance to change answers at this point), personally i did it to give the F5 Team my understanding of what they can improve! But they could give the cert away for the guys who passed this exam, yes it´s Christmas! :)

And yes, against other exams you can go back and forwarded!

All 5 sections have the same score, so i got 75%

I wrote a post about my Study Notes for this exam so check it out!

This exam is one of the pre-requirements for the Exam 201 – TMOS Administration to achieve the F5 BIG-IP Certified Administrator

Study Notes for F5 101v2-Application Delivery Fundamentals exam

As i said before i got an opportunity to test my knowledge (101v2 beta) and off course learn more about F5 ADC and other stuff. The information you need to learn is published in the official Blueprint Application Delivery Fundamentals. This new version will be available on Q1 2015.

F5 doesn´t have any guide (book,etc) like most of the vendors have, so you need to do it by your self. But i found a nice compilation did by Philip Jönsson (direct link) and another one by Rich Hill

A good tool is F5 University where you have free WBTs of LTM&APM (and more!!!), and hands-on on a virtual lab (code 10.x and 11.x). I think the most important are:

Getting Started with BIG-IP: Part 1 – Administration

Getting Started with BIG-IP: Part 2 – Application Delivery

Getting Started with BIG-IP Access Policy Manager (APM)

Getting Started with BIG-IP LTM: Part 1 – High Availability and Traffic Processing

Getting Started with BIG-IP LTM: Part 2 – iRules and Accelerating Traffic

Viprion Basics

HTTP Basics I

HTTP Basics II

A few facts:

  • The exam is based on 11.4.0 code
  • Exam cost 105 euros + VAT
  • The exam 101v2 will have 80 questions (70 scored and 10 unscored), and a minimum of 69% to pass it
  • Pre-requirement to go to the next level Exam 201 – TMOS Administration and be a F5 Certified BIG-IP Administrator (F5-CA)
  • All questions are scored equally
  • Passing the exam will be valid for 2 years
  • Most people agree that the v2 practice exam is much harder than the v1 production exam (mostly because of the number of questions).

I took the followed information from http://veritablenetworks.blogspot.pt/(Rich Hill) and change a few things for the renewed exam (101v2).

You can download my personal notes here.

Section 1 – OSI

Most of this information is common knowledge in the networking industry, but you probably don´t a few things especially when you get to the application layer protocols (sorry if i undervalue you!). The Wikipedia articles play a big role here, and yes Wikipedia Rulez!

In this section, we get into the actual F5 Solutions. Most engineers taking this exam will be experienced with LTM and iRules, but little else. Hopefully, the familiarity gained from the F5 datasheets and white papers shown below will help you to understand the breadth of the F5 offerings. Prepare to take the first step into a larger world.

Section 3 – Load Balancing Essentials

This section is a short one compared to the previous two. If you’re going after an F5 certification, you’re probably already familiar with much of this material, so you probably won’t have to study as much for this section. It never hurts to brush up on the algorithms and persistence methods.

  • Objective 3.01 – Discuss the purpose of, use cases for, and key considerations related to load balancing

Load Balancing Wiki
Load Balancing 101
Load Balancing Algorithms (Devcentral)
More on Load Balancing Algorithms

FREE 101-Application Delivery Fundamentals practice exam

I got this email on my inbox, it´s a good opportunity to test my knowledge :)

Dear 101 Candidate,

A few months ago, we surveyed the F5 Certified! candidates to find out what they were looking for to help them achieve their certification.  One of the top two items was exam-specific practice exams.  In response to that, we are pleased to announce that we are releasing our first “practice exam” opportunity for candidates eligible to take exam 101 – Application Delivery Fundamentals, but who have not yet done so. You are one of those eligible candidates.

Beginning October 20, 2014, qualified candidates will be able to register to take a FREE 101-Application Delivery Fundamentals practice exam, available at all F5-authorized Pearson VUE test centers. The practice exam will help you prepare for exam 101 by introducing you to the format of the questions, topics covered, and alert you to areas you might need to study. The FREE practice exam is 150 minutes long, features 140 questions, and will provide immediate performance results including per-objective scoring to help you better gauge your readiness to take a production exam. Your participation in taking a practice exam will provide you with the confidence to take the next step and help us to gauge the value in providing practice exams in the future.

HERE IS THE CATCH – we cannot offer free practice exams forever.  These exams will only be available from November 3, 2014 – November 24, 2014; furthermore, we can only accommodate a limited number of candidates.  Consequently, a LIMITED NUMBER OF SEATS are available for this exam and EARLY REGISTRATION is highly recommended to get a guaranteed spot. When we exceed the number seats, registration will cease.

Here is how to get started:

  • On October 20, 2014, log into the F5-CMS and visit your Home page. The exam will NOT be available before October 20th.
  • Click on the 101 Practice Exam ad box (it’s the black one).
  • Submit the 101 Practice Exam candidate agreement form.
  • In 24-48 hours, after receiving your authorized to test email, log into Pearson VUE and schedule your practice exam at the Pearson VUE test center near you.
  • Exam scheduling begins October 20, 2014 with the first exams available on November 3, 2014.
  • A LIMITED NUMBER of FREE practice exams are available; if you can’t schedule your exam after receiving your authorized to test email, you may be too late.

After login in F5-CMS sign up using the link “Take the 101 Practise Exam”
