For many years computing devices were built with two tiers. Consumer grade and Enterprise grade. Enterprise grade delivered high availability, quality components, redundant part and circuits and as a result came with a price tag that reflected this. This applies to routers, switches, machinery, servers and many facets of infrastructure. Consumer grade on the other hand was made for a function to a price point.

It can be summarised as the following: Consumer – best effort, low quality, minimal testing Enterprise – guarantees, high quality, extensive testing This was expected and if anything what was mandated for decades. Enterprise were the cutting edge and required the absolute best to do business. Reverse polarity? Yet there seems to be a slight paradigm shift … Continue reading

Whilst I have a great design being fleshed out for VCDX the VCP and VCIX are pre-requisite exams. Being an NSBU SE at VMware I took the exam without studying. At the PearsonVUE test center I clicked begin. 120 questions in 120 minutes is what they give you. I was travelling the week of the exam and had a customer meeting move so I booked in. I had 120 questions to do in 80 minutes by the time I started as I had a customer meeting in 95 minutes time. Eep! The Quality This ain’t the first rodeo for myself when it comes to exam certifications. I have … Continue reading
