Your company uses Office 365 and has an Enterprise E3 license plan. Employees are issued laptop computers that are configured with a standard image. The
image includes an installation of Office 365 ProPlus that must be activated by the employees.
An employee recently received a new laptop computer to replace an older laptop. The older laptop will be reimaged. When the employee attempts to start Word for
the first time, she receives a message saying that she cannot activate it because she has already activated five devices.
You need to help the employee activate Office on her new laptop computer.
What should you do?

A.
Assign a second E3 license to the employee.

B.
Remove the employee’s E3 license and then assign a new E3 license.

C.
Sign in to the Office 365 portal as the employee and deactivate the old laptop.

D.
Sign in to the Office 365 portal by using your Global Admin account and then deactivate the old laptop

Explanation:

The question states “You need to help the employee activate Office on her new laptop computer.” Deactivating Office on a particular device for a specific user can
be done with either C or D, but the main difference is that with D you are deactivating it for the user. Sure you could walk the user through doing it themselves or
have them login for you and then deactivate it, or you could be a bad ass and just do it for them from your Global Administrator account 🙂
Sign into the Office 365 Portal -> Users -> Active Users -> Select User Name -> Edit Office Installations and pick the device you want to remove.
