Your network contains an Active Directory domain. The domain contains DNS servers that run Windows Server 2008 R2. The network has two external links. One link connects to the Internet.

The other link directly connects to the network of a partner company. The partner companys network is not connected to the Internet. You need to ensure that users on your network can access resources on the partner companys network. The solution must ensure that the users on your network can continue to access resources on the Internet. Which two actions should you perform on the DNS servers? (Each correct answer presents a complete solution. Choose two.)

Your company has a domain controller named Server1 that runs Windows Server 2008 R2 and the DNS Server server role. A server named Server2 runs a custom application. You need to configure DNS to include the following parameters for the custom application:

Service

Priority

Weight

Protocol

Port number

Host offering this service

Which record should you create?

Your company has a domain controller named Server1 that runs Windows Server 2008 R2 and the DNS server role. A server named Server2 runs Windows Server 2003 and Microsoft Exchange Server 2007.

The company wants to deploy a new Exchange server named Server3 to receive all inbound e- mail traffic.

You need to configure DNS to direct incoming e-mail traffic to the Exchange servers. You also need to ensure that higher priority is given to Server3.

What should you do?

Your company has a domain controller that runs Windows Server 2008 R2 and the DNS role. The DNS domain is named contoso.com.

You need to ensure that inquiries about contoso.com are sent to dnsadmin@contoso.com. What should you do?

You are building a test environment to evaluate DNS Security Extensions (DNSSEC). You have a domain controller named Server1 that runs Windows Server 2008 R2 in your test environment.

Server1 has the DNS Server server role installed.

You need to configure Server1 to support the DNSSEC evaluation. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

Your company has a server that runs Windows Server 2008 R2. You have a new application that locates remote resources by name. The new application requires IPv6.

You need to ensure that the application can locate remote resources by using IPv6. What should you do?

Your company has a single Active Directory domain. All servers run Windows Server 2008 R2. You install an additional DNS server that runs Windows Server 2008 R2. You need to delete the pointer record for the IP address 10.3.2.127.

What should you do?

Your network contains an Active Directory domain. The domain contains an enterprise certification authority (CA) named Server1 and a server named Server2. On Server2, you deploy Network Policy Server (NPS) and you configure a Network Access Protection (NAP) enforcement policy for IPSec. From the Health Registration Authority snap-in on Server2, you set the lifetime of health certificates to four hours. You discover that the validity period of the health certificates issued to client computers is one year.

You need to ensure that the health certificates are only valid for four hours. What should you do?

Your company has a main office and two branch offices that are connected by WAN links. The main office runs the DNS Server service on three domain controllers. The zone for your domain is configured as an Active Directory-integrated zone.

Each branch office has a single member server that hosts a secondary zone for the domain. The DNS servers in the branch offices use the main office DNS server as the DNS Master server for the zone. You need to minimize DNS zone transfer traffic over the WAN links.

What should you do?

Your network contains an Active Directory domain named contoso.com. All domain controllers run Windows Server 2008 R2 and are configured as DNS servers. All client computers run Windows

7. You create a new zone named secure.contoso.com and configure the zone to use DNSSEC. You need to ensure that all client computers verify whether the name and address information of secure.contoso.com is validated by the DNS servers. What should you configure from Group Policy?
