Hi,
A problem with your question is that people that took the ACMX exam are not allowed to talk about it or share any of its content.
What would probably help you is reading the ACMX reference guide that is available on the Aruba website (direct link: http://www.arubanetworks.com/assets/training/ERG_ACMX.pdf). In this document, you can read things like:
"Note that you are not expected to provision any third party components. Your responsibility is to successfully deploy the Aruba system to support the features in your exam. For example, this may involve the usage of third party elements such as Voice Phones. But you will not be required to provision the phones."
.. and...
"We use AirWave version 8.0 in the exam. You are expected to be able to provision the Aruba network to be seen and monitored by the AirWave server."
It also mentions what areas are tested.
Success in preparing for your exam!
Herman
