You administer computers that run Windows 10 Enterprise and are members of an Active Directory domain.
The computers are encrypted with BitLocker and are configured to store BitLocker encryption passwords in
Active Directory.
A user reports that he has forgotten the BitLocker encryption password for volume E on his computer. You
need to provide the user a BitLocker recovery key to unlock the protected volume.

Ask the user for his computer name.

B.
Ask the user to run the manage-bde-unlock E:-pw command.

C.
Ask the user for his logon name.

D.
Ask the user for a recovery keyID for the protected volume.

In Active Directory Users and Computers, locate and then click the container in which the computer is
located.
Right-click the computer object, and then click Properties.
In the Properties dialog box, click the BitLocker Recovery tab to view the BitLocker recovery passwords that
