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:
Red down arrow indicates an unauthorized DHCP server
by default Allow filters is disabled to let every PC on the network get IP address from the DHCP server. The image above show that Allow filter was enabled causing some PC on the network not able to get ip address.
Thanks for the reply drin!
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.
