Hey, I surely did this just last year and not in 2020, didn’t I? Well, the Linux Foundation said otherwise and here is my re-take experience. I cleared the CKA exam with a score of 91%, so I feel rather confident to write about it.https://www.why-did-it.fail/blog/2019-03-vcdx-design-requirements/Tue, 15 Jan 2019 00:00:00 +0000https://www.why-did-it.fail/blog/2019-03-vcdx-design-requirements/This blog post has not the intend to define what a requirement/constraint is, there are already very good posts out there. Lately I pointed a lot of people over to Jeffrey Kusters who did an excellent job of summarizing it but I included also two other good links: https://www.jeffreykusters.nl/2018/06/25/breaking-down-the-conceptual-design-rcars-and-amprs-vcdx-style/ http://www.i-1.nl/blog/?p=58016 https://blog.jgriffiths.org/advice-to-vcdx-candidates-from-a-double-vcdx/ What is this about?

However, some basic training got me from “zero” to at least one step further - more or less readable handwriting. We all take it for granted - there is a whiteboard in the room and we all know how it works, right?

Easily the longest supporter of my efforts has been Bilal Ahmed. In his always good natured way he managed to guide me since VCAP design-days with solid advice and motivation.
