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.

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.

Your company has a main office and two branch offices. The main office is located in London. The branch offices are located in New York and Paris. Your network consists of an Active Directory forest that contains three domains named contoso.com， paris.contoso.com， and newyork.contoso.com. All domain controllers run Windows Server 2008 R2 and have the DNS Server server role installed. The domain controllers for contoso.com are located in the London office. The domain controllers for paris.contoso.com are located in the Paris office. The domain controllers for newyork.contoso.com are located in the New York office. A domain controller in the contoso.com domain has a standard primary DNS zone for contoso.com. Adomain controller in the paris.contoso.com domain has a standard primary DNS zone for paris.contoso.com. A domain controller in the newyork.contoso.com domain has a standard primary DNS zone for newyork.contoso.com. You need to plan a name resolution strategy for the Paris office that meets the following requirements： èIf a WAN link fails， clients must be able to resolve hostnames for contoso.com. èIf a WAN link fails， clients must be able to resolve hostnames for newyork.contoso.com. èThe DNS servers in Paris must be updated when new authoritative DNS servers are added tonewyork.contoso.com. What should you include in your plan？（）
A.Configure conditional forwarding for contoso.com. Configure conditional forwarding for newyork.contoso.com.
B.Create a standard secondary zone for contoso.com. Create a standard secondary zone for newyork.contoso.com.
C.Convert the standard zone into an Active Directory-integrated zone. Add all DNS servers in the forest to the root hints list.
D.Create an Active Directory-integrated stub zone for contoso.com. Create an Active Directory-integrated stub zone for newyork.contoso.com.
