What should you create on Server1?

Your network contains three servers that run Windows Server 2012. The servers are configured as shown in
the following table.

Server3 is configured to obtain an IP address automatically.
You need to prevent Server3 from receiving an IP address from Server1.
What should you create on Server1?

A.
A reservation

B.
A filter

C.
A scope option

D.
An exclusion

Explanation:
A: For clients that require a constant IP address
B: Filter to exclude MAC address of Server3
C: Range of allowed IP’s to be assigned
D: Exclude range of IP’s
MAC address based filtering ensure that only a known set of devices in the system are able to obtain an
IPAddress from the DHCP

Reservation and Exclusion, two incredibly differentconcepts. An exclusion is an address or range of addresses
taken from a DHCP scope that the DHCP server is notallowed to hand out. For example, if you have set a
DHCP server to exclude the address range 192.168.0.1-192.168.0.10 then the only way a computer on your
network would get an address of 192.168.0.4 would be ifyou assigned it statically on that machine. This is
because DHCP knows NOT to give this range of IPaddresses out.
A reservation is a specific IP addresses that is tied to a certain device through its MAC address. Forexample, if
we have a workstation on the network that requires a certain IP address, but we don’t want to gothrough to
trouble of assigning it statically, then we can create a reservation for it. So if the MAC address of theNIC on the
computer is AA-BB-00- FF-CC-AA and we want it to maintain the IP address of 192.168.0.100 thenwe would
create a DHCP reservation under that particular scope saying that the IP address 192.168.0.100 isreserved
only for the MAC address AA-BB-00-FF-CC-AA.
