Your network contains an Active Directory domain named contoso.com. The domain
contains five servers. The servers are configured as shown in the following table.
All desktop computers in contoso.com run Windows 8 and are configured to use BitLocker
Drive Encryption (BitLocker) on all local disk drives.
You need to deploy the Network Unlock feature. The solution must minimize the number of
features and server roles installed on the network.
To which server should you deploy the feature?
A.
Server1
B.
Server2
C.
Server3
D.
Server4
E.
Server5
Explanation:
The BitLocker Network Unlock feature will install the WDS role if it is not already installed. If
you want to install it separately before you install BitLocker Network Unlock you can use
Server Manager or Windows PowerShell. To install the role using Server Manager, select
the Windows Deployment Services role in Server Manager.
