Your network contains an Active Directory domain named contoso.com. The domain contains a domain
controller named DC1 that runs Windows Server 2012 R2 and a client computer named Computer1 that runs
Windows 8. DC1 is configured as a DHCP server as shown in the exhibit. Computer1 is configured to obtain an
IP address automatically.

Explanation:
A red down arrow indicates an unauthorized DHCP server. A DHCP server that is a domain controller or a
member of an Active Directory domain queries Active Directory for the list of authorized servers (identified by IP
address). If its own IP address is not in the list of authorized DHCP servers, the DHCP Server service does not
complete its startup sequence and automatically shuts down.
