On January 22 2021, I successfully passed the 2V0-41.20 exam based on NSX-T 3.0 which made me a new happy VCP-NV. I thought it would be nice to share with you my experience with this exam.
How to prepare for the exam
For the record, I was initially going for the NSX-T 2.4 exam before it expires but I found myself pretty busy so I preferred to wait a little bit and get prepared for version 3.0.
I sat a while back for the NSX-T 2.4 ICM class that helped me a lot to understand the product. I have to say that this was one of the best course I ever had and I’d like to thank again the instructor Christian Regent who became later on my VCI mentor 🙂
Recently I was in charge of designing and implementing a new vSphere and vSAN infrastructure for a customer.
Everything went just fine, except that we all have experienced many network outages due to misconfiguration of some Firewall Virtual Appliances where the whole infrastructure relies on.
As a result, all ESXi got disconnected from the vCenter and this happened many times!
Anyway, the network team in the end fixed the issue and the network was finally stable but I have to say that I’m not a fan of firewall virtual appliance as it brings some limitations and complexity. Unfortunately, those outages had a bad impact on the virtualization network as some warnings appeared showing some ESXi hosts out of sync with the distributed switch.
This could not be a big deal at the beginning but this kind of issue definitely needs to be addressed to avoid any network problem in the future.
