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 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.
