next several months.
You need to plan the most efficient method for activating all of the computers.
What should you do?

Use Multiple Activation Key (MAK) Independent forthe first 200 computers, and then use Multiple Activation
Key (MAK) Proxy for the remaining computers.

B.
Use the Key Management Service (KMS) for all the computers.

C.

D.

Explanation:
MAK
If users install a MAK using the user interface (UI), the MAK client attempts to activate itself over the Internet
one time. If the users install a MAK using the Slmgr.vbs script, the MAK client does not try to activate itself
automatically.
