Juniper Networks Certified Expert Data Center (JNCIE-DC) Open for Registration

At the pinnacle of the Data Center certification track is the 1-day JNCIE-DC practical exam. This exam is designed to validate the networking professionals’ ability to deploy, configure, manage, and troubleshoot Junos-based platforms. Throughout this 8-hour practical exam, candidates will build a data center network consisting of multiple MX Series and QFX Series devices. Successful candidates will perform system configuration on all devices including management capabilities, a Clos IP fabric, EVPN/VXVLAN, DCI, and CoS features.

The JNCIE-DC is valid for three years. Recertification is achieved by passing the current version of the JNCIP-DC exam or by attending a corresponding course.

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!

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)
