The main intent of the Masters is (from my experience) is for pre-sales people.
Be able to produce coherent and relevant demos and sales pitches (not my strong point.)
Ensure that sales and design teams are selling workable Meraki solutions and designs to customers.
Be a company representative that is aware of new and upcoming Meraki features and products.
Lets say that I can't say too much about the coherent design business but most design teams try to treat Meraki (and other cloud based solutions) in the same manner as regular Wi-Fi solutions (controllers located in a DC) and that route leads to some big and very avoidable issues.
I did ask if there could be another purely technical qualification created and the suggestion was noted and I hope that something turns up.
