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. (Click the Exhibit button.)
Computer1 is configured to obtain an IP address automatically.
You notice that Computer1 is unable to obtain an IP address from DC1.
You need to ensure that Computer1 can receive an IP address from DC1.
What should you do?
A.
Disable the Allow filters.
B.
Disable the Deny filters.
C.
Authorize DC1.contoso.com.
D.
Activate Scope [10.1.1.0] Contoso.com.
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.
I think A is incorrect and correct answer should be C based on the provided explanation.
“A” is the correct answer. A red down arrow indicates that the filter is disabled. The Allow filter is active as shown in the exhibit and thus the Allow filter needs to be disabled otherwise only device in the Allow filter can obtain an IP.

From the icons you can see that the dhcp server is authorized, however as Ben above says: the Allow filter is enabled, This means that the systems mac adress must be added to be able to get the ip-adress. Hence disabling it will stop all filtering.
