The Juniper offices are closed because of COVID-19 and the lab exam is conducted remotely. Taking the labĪs I took the lab in March of 2021. To brush up on all the knobs and features I read parts of the Juniper documentation which has excellent sample configurations explaining what’s needed and why. I did not read books as a preparation, but you do need a solid understanding of routing protocols, MPLS and EVPN. The performance was amazing and I could spin up as much virtual resources as I wanted to test various topologies.

My Dell R730 server running bare-metal EVE-NG Pro was a life saver during the preparation. Then it really helps by taking the documentation and checking it by yourself to know if your variant is just as right as the configuration in the workbook is. Sometimes this made me doubt my own solution of which I was sure was correct as well.
When working through the labs of the workbook you will find that some solutions will not have much explanation other than the correct configuration. Again a feature only supported on QFX5100 (and QFX5110/EX4300), not on the vQFX. The same goes for Virtual Chassis Fabric. This means you really have to be aware of the physical limitations of the platform when applying Class of Service configuration. Note that it does not cover 100% of the topics and you will need to read documentation and have a deep understanding of the technologies on the blueprint of the test.Įxamples of this are working with Class of Service configuration on QFX5100 platforms, as the lab only works on vQFX devices which are based on a virtual Q5 PFE rather than a Trident2 chip as used in the QFX5100. This will prepare you for 95% of the test. The Juniper Education self-study workbook for the JNCIE-DC lab is by far my most used resource for the lab.
After committing to the goal of passing the test in Q1 of 2021 I really picked up the pace and started studying multiple nights a week and came into the flow I like to be when preparing for a lab exam. I was also a champion in delaying my actual start of preparation. Being exposed to the platforms and technologies used gave me a head start, but after really starting to lab the different topics I really felt I had a long way to go. ResourcesĪs I’m working with different cloud provider customers in my daily job it really helped in preparing for this test. In this conclusion of the previous JNCIE-DC blogs about my lab setup and about the remote lab environment, I will talk about my experience of taking the lab and how I’ve prepared. After plenty of hours of studying and labbing the wide ranging topics on the JNCIE-DC blueprint, I took the JNCIE-DC lab exam and passed! I can proudly say I’m JNCIE-DC #389.
