A company plans to deploy Windows 8.1 to 100 client computers. Each client computer has
8 GB of memory.
You have the following requirements:
Ensure that the operating system fully utilizes the available memory.
Ensure that the operating system can be activated by using a Key Management Service
(KMS) client setup key.
Minimize the operating system space requirements.
You need to identify the appropriate edition of Windows 8.1 to install on the client computers.
Which edition should you install?
A.
Windows 8.1 Enterprise 32-bit
B.
Windows 8.1 64-bit
C.
Windows 8.1 Pro 32-bit
D.
Windows 8.1 Enterprise 64-bit
E.
Windows 8.1 Pro 64-bit
F.
Windows 8.1 32-bit
Windows 8.1 pro x64 utilizes KMS & memory above 4 GB

Windows 8.1 Ent x64 has the additional features: Windows To Go, DirectAccess, BranchCache, AppLocker, Virtual Desktop Infrastructure (VDI), and Windows 8 app deployment

You would think that these additional feature consume disk space.
To meet the requirement “Minimize the operating system space requirements”, I would go for “Windows 8.1 Pro 64-bit”
