2.1. Domain 1.0 - Operating Systems

What happens when you choose the wrong filesystem for a server? Think of it like building a house on the wrong foundation—NTFS supports permissions and encryption that FAT32 simply can't provide. Without the right OS and filesystem choices, you'll face limitations that no amount of troubleshooting can fix.

This domain covers 28% of the exam. You'll need to understand not just what each OS does, but when to use each one and why certain configurations matter. Consider: when would you recommend Windows Pro over Home? What breaks if you format a boot drive as FAT32 instead of NTFS?
