You are designing a DNS implementing strategy to meet the business and technical requirement. Which type of zone should you use?（）

A.Configure each server running Routing and Remote Access as a RADIUS Client.  
B.Add a Remote Access policy to each server running Routing and Remote Access. Configure the Access method as VPN access.  
C.Add a Remote Access policy to each server running Routing and Remote Access. Configure the Access method as dialup access.  
D.Add a Remote Access policy to each server running Routing and Remote Access. Configure the Access method as wireless access.  

A.Create a Stub Zone in each domain of the root zone.  
B.Create a _msdcs subdomain in a new zone on the root domain. 
C.Replicate the _msdcs subdomain across the roor domain.  
D.Replicate the _msdcs subdomain to the ForestDNS zone applciation partition.  
E.Configure a zone transfer of the _msdcs subdomain to secondary zone on all DNS servers in the forest.

A.Create a reverse lookup zone in DNS for each new Domain.
B.Add a WINS lookup record to the DNS forward lookup zone.
C.Add a WINS reverse record to the DNS reverse lookup zone.
D.Enable Dynamic updates for DownLevel client computers on each DHCP server.
E.Install the Active Directory Client on All Computers in the Customer service department.
