On 1 February 2017 I passed my VMware VCAP6-DCV Deployment exam (3V0-623).
For the exam I studied for about two months. To exercise all the objectives I build in my Home Lab a vSphere 6.0 environment for passing all blueprint objectives.
There are two unofficial study guides available on the internet. These are based on the VMware Blueprint and they helped me a lot.
The guides are detailed and full of information.
