You need to ensure that when you right-click DC2, you see the option to run DNS Manager

Your network contains an Active Directory domain named contoso.com. The domain contains a member server
named Server1 and a domain controller named DC2. All servers run Windows Server 2012. All domain
controllers are configured as DNS servers. On Server1, you open Server Manager and you add DC2 as another
server to manage.
From Server Manager on Server2, you right-click DC2as shown in the exhibit. (Refer to the Exhibit.)
You need to ensure that when you right-click DC2, you see the option to run DNS Manager.
What should you do?

A.
In the domain, add Server1 to the DNS Admins group.

B.
On DC2 and Server1, run winrmquickconfig.

C.
On DC2, install the Feature Administration Tools.

D.
On Server1, install the Role Administration Tools.

Explanation:
If you have installed Windows Server 2012 Roles andFeatures using PowerShell or remote server admin
toolsor new multi server manager console, you will see that the management tools are missing from the server
onwhich you just have enabled the role or feature. This is because Microsoft has provided more granular
controlon what is installed on the Windows Server 2012. As an administrator we have choice to include or not
toinclude management tools while installing the Roles and Features we choose.
The goal for Windows Server 2012 administration is to manage remotely from Windows Server 2012 box
thatwill act as the management host for all serversand will be accessed by all the IT administrators.
Typically, when a role is installed, the associatedadministration tools are also installed. However, sometimes
you simply need to add additional administrative tools.
