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.
According to picture the DHCP service is already authorized. There are green hooks on both the IPv4 and IPv6 server icons. So the answer cannot be Authorized
Under the Filters folder there is Allow subfolder. This is now enabled because there is no red downward-pointing arrow. When one disables the Allow filtering feature the DHCP server will be able to distribute ip addresses.
So I think the answer is A.
Note: Do not Enable the Allow list! Doing so will cause DCHP to operate on a “Whilelist” which require you to create an Allow List entry for every MAC address that should be given an IP address. By default, DHCP operates on a “Blacklist” which allows all MAC’s to be given an IP except for ones explicitly defined on the Deny List.

this is the actual picture
if you look in detail you’ll see that scope is 10.0.0.0 and it must be 10.1.1.0
if so then the answer in A
no?

I reproduce the situation in my lab, with this picture the answer for sure is A. chaserZX explain it correctly.

I agreed with chaserZX . Tried this on my lab. Based on the pic DC1.contoso.com was already authorized. Since allow filter doesnt have a red down arrow on it. it needs to be disabled.
