this is a new Microsoft exam which is currently under development, but it alot of interesting points which Microsoft should have focus on a long time ago in terms of training! Security!
The exam is of course based upon a training course –> https://www.microsoft.com/en-us/learning/course.aspx?cid=20744
But the exam it self focuses on Securing network traffic, DNSSEC, Microsoft ATA, Breach detection using SysInternal tools, Credential Guard, JEA (Just enough administration) AppLocker, Use of OMS, BitLocker, Containers and so on.

And oh, a study guide is in the making!
