Your network contains an Active Directory domain named contoso.com. The domain
contains a domain controller named DC1 that runs Windows Server 2012 R2. DC1 has the
DHCP Server server role installed.
DHCP is configured as shown in the exhibit. (Click the Exhibit button.)
You discover that client computers cannot obtain IPv4 addresses from DC1.
You need to ensure that the client computers can obtain IPv4 addresses from DC1.
What should you do?
A.
Activate the scope.
B.
Authorize DC1.
C.
Disable the Allow filters.
D.
Disable the Deny filters.
Explanation:
There is no items in the deny List. So it means that client computers MAC addresses is not
listed in the allow list. So we have to disable the “Allow Filters”

I think it’s C.
The scope is activated, DC1 ia authorized and the Deny filters is empty.
Answer = C

Before you can configure MAC address filtering, you must do the following:
* Enable and define an explicit allow list. The DHCP server provides DHCP services only to clients whose MAC addresses are in the allow list. Any client that previously received IP addresses is denied address renewal if its MAC address isn’t on the allow list.
Enable and define an explicit deny list. The DHCP server denies DHCP services only to clients whose MAC addresses are in the deny list. Any client that previously received IP addresses is denied address renewal if its MAC address is on the deny list.
Enable and define an allow list and a block list. The block list has precedence over the allow list. This means that the DHCP server provides DHCP services only to clients whose MAC addresses are in the allow list, provided that no corresponding matches are in the deny list. If a MAC address has been denied, the address is always blocked even if the address is on the allow list.

By enabling the allow list, you automatically deny access to the DHCP server addresses to any client computer not on the list.
So answer is C:
The server is authorised and the scope is activated, also there are no users in the deny filter.
Therefore you have to assume that there are no users in the allow filter and as a result no users allowed to login. So the answer is C
Correct, the exhibit should show the Allow node, or both Allow and Deny to really make a decision. Answer is C
The Deny option is highlighted and the right pane is empty. So no computer is being denied. Yet “You discover that client computers cannot obtain IPv4 addresses from DC1.” The only possible thing that could be preventing this is that the Allow list is empty, which would result in disallowing every computer. So C is correct: Disable the Allow filters. And then all will now be allowed.
