Whilst this isn’t an objective on the VCAP-DTD exam blueprint, It’s a requirement in any design to understand the maximums of a product you are designing.
Andre Leibovici over at myvirtualcloud.net has already blogged about this (thanks Andre!) so to save re-inventing the wheel here is a link to his post http://myvirtualcloud.net/?p=2455
I appreciate this Horizon 5.2 is now available, however the VCAP-DTD exam is based on View 5.0. Andre has also blogged about Horizon View 5.2 Maximums and limits here http://myvirtualcloud.net/?p=4432
