Congrats and good job!
A few questions from someone who is just starting to study for it:
How many years experience do you have from working with Aruba?
For how long did you study?
Without breaking NDA or rules:
Does the exam guide (http://www.arubanetworks.com/assets/training/ERG_ACDX.pdf) correspond correctly with the questons on the test?
Two of the recommended traning is about 802.11n, is it better to study the documents about .11ac?
Regards
Philip
