You have a DHCP server named Server1.
Server1 has an IP address 192.168.1.2 is located on a subnet that has a network ID of 192.168.1.0/24.
On Server1, you create the scopes shown in the following table.

You need to ensure that Server1 can assign IP addresses from both scopes to the DHCP clients on the local subnet.
What should you create on Server1?

A.
A scope

B.
A superscope

C.
A split-scope

D.
A multicast scope

Explanation:
A)
A scope is an administrative grouping of IP addresses for computers on a subnet that use the Dynamic Host Configuration Protocol (DHCP) service. The
administrator first creates a scope for each physical subnet and then uses the scope to define the parameters used by clients.
B)
A superscope is an administrative feature of Dynamic Host Configuration Protocol (DHCP) servers running Windows Server 2008 that you can create and
manage by using the DHCP Microsoft Management Console (MMC) snap-in. By using a superscope, you can group multiple scopes as a single administrative
entity.
D)
Multicasting is the sending of network traffic to a group of endpointsdestination hosts.
Only those members in the group of endpoints hosts that are listening for the multicast traffic (the multicast group) process the multicast traffic
