You have a DHCP server named Server1. Server1 has one network adapter. Server1 is located on a subnet
named Subnet1. Server1 has scope named Scope1. Scope1 contains IP addresses for the 192.168.1.0/24
network. Your company is migrating the IP addresses on Subnet1 to use a network ID of 10.10.0.0/16. On
Server11 you create a scope named Scope2.
Scope2 contains IP addresses for the 10.10.0.0/16 network.
You need to ensure that clients on Subnet1 can receive IP addresses from either scope.
What should you create on Server1?

A.
A multicast scope

B.
A scope

C.
A superscope

D.
A split-scope

Explanation:
A:
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
B:
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.
C:
A superscope is an administrative feature of Dynamic Host ConfigurationProtocol (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.
