There are two main things that are likely to cause problems for you on this exam. One is the lack of study materials. The other is the variety of products that you will need to be familiar with in order to pass this exam.
The exam focuses primarily around Microsoft Forefront Endpoint Protection, but you will also need to know how to deploy and configure the various Forefront Application Protection products. The exam places an especially heavy emphasis on Forefront Protection for SharePoint, but you will also need some knowledge of Forefront Protection for Exchange as well. This means that you will have to have some Exchange and SharePoint knowledge. For instance, you will have to be familiar with the Exchange Server roles (mailbox, hub transport, client access, edge transport, and unified messaging) and you will need to know how an Exchange server’s role impacts the way that Forefront has to be installed.
You will also have to be familiar with the way that Forefront ties in with your management servers. This primarily involves WSUS and System Center Configuration Manager.
