You are the systems administrator for your company. The company’s network consists of a single Active Directory domain with five domain controllers. The network contains Windows Essential Business Server (EBS) 2008. The network also contains a Domain Name System (DNS) server and a Dynamic Host Configuration Protocol (DHCP) server.

The Security Server fails due to a hardware failure. You want to replace the server with a new server.

Which two servers will be required during the replacement process? (Choose two. Each correct answer presents part of the solution.)

A.
a domain controller

B.
the DNS server

C.
the DHCP server

D.
the Management Server

Explanation:
A domain controller and the DNS server will be required during the replacement process. You can replace a server for Windows EBS in the event a hardware failure occurs or if you want to upgrade any of the servers to a new computer. The Windows EBS Installation Wizard allows you to replace the servers running Windows EBS. You should use the appropriate DVD for the server that you want to replace. For example, to replace the Security Server, you should use the DVD for installing the Security Server. Both DNS and Active Directory Domain Services (AD DS) are required during the replacement process. Therefore, before starting the replacement process, you must ensure that the primary or the alternate DNS server is running and you can connect to it. You must also ensure that an AD DS domain controller is running and you can connect to it.

The options stating the DHCP server and the Management Server are incorrect because these servers are not required while replacing the Security Server for Windows EBS.
