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 ofIP 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 anadministrative 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 asingle administrative entity.
D:
