Domain.com has employed you as a network administrator. The Domain.com network consists of a single Active Directory domain named Domain.com. All servers on the Domain.com network run Windows Server 2008. Half the client computers run Windows XP Professional, and the rest run Windows Vista.
The Domain.com network contains two domain controllers named CERTKILLER-DC01 and CERTKILLER-DC02. CERTKILLER-DC01 is configured to host the Schema Master Role. During
the course of the day you discover that CERTKILLER-DC01 has failed. In order to rectify the problem you log on to the Active Directory using the administrator account. You attempt to transfer the Schema Master Operations role but are unsuccessful in accomplishing this task. Management wants you to make sure that CERTKILLER-DC02 is configured to host the Schema Masters Role.
What should you do?

A.
Your best option would be to configure CERTKILLER-DC02 as a Primary domain controller.

B.
Your best option would be to seize the Schema Master role on CERTKILLER-DC02.

C.
Your best option would be to register Schemamt.dll on the Active Directory domain.

D.
Your best option would be to join the Schema Administrators group.

Explanation:
Thereafter the Active Directory Schema snap-in can be started.
Thereafter the Schema settings should be modified to save records on CERTKILLER-DC02.
To ensure that CERTKILLER-DC02 holds the Schema Master role you need to seize the Schema Master role on CERTKILLER-DC02. Seizing the schema master role is a drastic step that should be considered only if the current operations master will never be available again. So to transfer the schema master operations role, you have to seize it on CERTKILLER-DC02.
