You have an offline root certification authority (CA) named CA1. CA1 is hosted on a virtual machine.

You only turn on CA1 when the CA must be patched or you must generate a key for subordinat

e CAs.

You start CA1, and you discover that the filesystem is corrupted.

You resolve the filesystem corruption and discover that you must reload the CA root from a backup.

When you attempt to run the

R

estore-CARoleService

cmdlet, you receive the

following error message: -The process cannot access the file because it is being used by another process.-

You need to ensure that you can restore the CA.

What should you do first?

A. Stop the Active Directory Certificate Services (AD CS) service.

B. Ru

n the

Restore-CARoleService

cmdlet and specify the

-Force

parameter.

C. Stop the Active Directory Domain Services (AD DS) service.

D. Run the

Restore-CARoleService

cmdlet and specify the path to a valid CA key.
