单项选择题

Your network contains two DHCP servers. The DHCP servers are named DHCP1 and DHCP2. The
internal network contains 1，000 DHCP client computers that are located on a single subnet. A routerseparates the internal network from the Internet. The router has a single IP address on the internal interface. DHCP1 has the following scope information.
èStarting IP address： 172.16.0.1
èEnding IP address： 172.16.7.255
èSubnet mask： 255.255.240.0
You need to provide a fault-tolerant DHCP infrastructure that supports the client computers on the internal network. In the event that a DHCP server fails， all client computers must be able to obtain a valid IP address.
How should you configure DHCP2？（）

A.Create a scope for the subnet 172.16.0.0/20. Configure the scope to use a starting IP address of 172.16.8.1 and an ending IP address of 172.16.15.254.
B.Create a scope for the subnet 172.16.0.0/21. Configure the scope to use a starting IP address of 172.16.0.1 and an ending IP address of 172.16.15.254.
C.Create a scope for the subnet 172.16.8.0/21. Configure the scope to use a starting IP address of 172.16.8.1 and an ending IP address of 172.16.10.254.
D.Create a scope for the subnet 172.17.0.0/16. Configure the scope to use a starting IP address of 172.17.0.1 and an ending IP address of 172.17.255.254.

单项选择题

Your network contains an Active Directory forest named contoso.com.
You plan to deploy a new child domain named branch.contoso.com. The child domain will contain two domain controllers. Both domain controllers will have the DNS Server server role installed.All users and computers in the branch office will be members of the branch.contoso.com domain.You need to plan the DNS infrastructure for the child domain to meet the following requirements： èEnsure resources in the root domain are accessible by fully qualified domain names.
èEnsure resources in the child domain are accessible by fully qualified domain names.
èProvide name resolution services in the event that a single server fails for a prolonged period of time.
èAutomatically recognize when new DNS servers are added to or removed from the contoso.com domain.
What should you include in your plan？（）

A.On both domain controllers， add a conditional forwarder for contoso.com and create a standard primary zone for branch.contoso.com.
B.On both domain controllers， modify the root hints to include the domain controllers for contoso.com. On one domain controller， create an Active Directory-integrated zone for branch.contoso.com.
C.On one domain controller create an Active Directory-integrated zone for branch.contoso.com and create an Active Directory-integrated stub zone for contoso.com.
D.On one domain controller， create a standard primary zone for contoso.com. On the other domain controller， create a standard secondary zone for contoso.com.
