I am currently working with NSX as part of the NSX ICM Course roll out in the EMEA. This is a great course for an amazing product.
As with most products within the VMware portfolio there has been a series of exams announced.
The VCP-NV has been announced but is not available yet. While prepping to deliver the course I have created a series of practice tests to help me work with the technical material.
Here is the link to the first – Hope it is useful.
