Recently I set my sights on Juniper Networks‘ Design track as I am working with customers on an almost daily basis with regards to Data Center design. As such the Juniper Network Design – Data Center curriculum and associated JNCDS-DC certification looked very appealing. To top that off, according to Certification Magazine, the JNCDA and the JNCDS-DC certifications are two of the top six design related certifications at the moment, as of October 2016.
Data Centers and the Cloud are all the rage right now, and Juniper has been at the forefront of the Data Center revolution from the very beginning – early on with their introduction of the QFX and the much maligned QFabric, and more recently with the addition of Virtual Chassis Fabric (VCF), various open architectures for creating IP Clos Fabrics, and even advanced features such as Junos Fusion for the Data Center which collapse and simplify the deployment and management of a large number of Ethernet switches.
The JNCIP-DC is currently rated as the fifth hottest Data Center certification by Tom’s IT Pro, an online resource tracking the demand of various industry certifications.
Juniper QFX5100 Series: A Comprehensive Guide to Building Next-Generation Networks
by Douglas Richard Hanks, Jr.
Paperback: 310 pages
Publisher: O’Reilly Media
Much more than just a book about the QFX5100
This was an easy weekend read, and quite honestly I’d never thought I’d say this about a technical book but I literally could not put the book down. Doug has amassed a wealth of great information, approaching the subject matter from a standpoint of brevity, applying the Goldilocks principle — not too much and not too little — but rather just the right amount of information.
Juniper took a big step forward in rounding out their certification programs by announcing a new Design Training and Certification curriculum, focusing on best practices and techniques that can be used across the spectrum of network architecture and design. Slated to be included in this program are also technologies around software-defined networking (SDN) and network functions virtualization (NFV).
Not a day that goes by since having passed the JNCIE-SEC exam that I don’t receive an inquiry in one form or another regarding how I prepared for the exam. It seems that there is an incredible amount of interest in this exam, especially from all those die-hard ScreenOS folks that are now converting to Junos. So instead of constantly repeating myself, I figured I’d just put it up on the blog so others can benefit (leaving me more time to do other things, ‘heh).
Today we’ll start with a series of articles covering tips and techniques that might be utilized by JNCIE candidates, whether pursuing the JNCIE-SP, JNCIE-ENT, or even the JNCIE-SEC. The tips and techniques I will be covering might prove to be useful during a lab attempt but could also be used in real-world scenarios to save time and minimize configuration burden in addition to eliminating mistakes that might otherwise be made. I want everyone to understand that what I am about to write is simply a technique. I am not divulging any materials or topics which are covered under NDA.
As many of you know, Juniper is currently undergoing a massive effort to update their certification program. The previous track in ‘Enterprise Routing’ is now changing to ‘Enterprise Routing and Switching’ incorporating elements from the previous certification track in addition to some new elements essential to Enterprise switching such as Spanning-Tree, VLANs, Layer 2 Security, as well as High Availability features like Virtual Chassis. We can expect that a lot of the topics like Firewalling and NAT will be removed from this exam as these topics will more properly appear in the Security track.
Although the new JNCIE-ENT certification is planned to be released in August 2011, there are many of you who are currently pursuing the existing JNCIE-ER before time runs out. The good news is that Juniper plans to continue offering the existing JNCIE-ER exam until October 2011 so there is still quite a bit of time for those who are interested in attaining this certification.
