Your company has an Active Directory domain. The main office has a DNS server named DNS1 that is configured with Active Directory-integrated DNS. The branch office has a DNS server named DNS2 that contains a secondary copy of the zone from DNS1. The two offices are connected with an unreliable WAN link.
You add a new server to the main office. Five minutes after adding the server, a user from the branch office reports that he is unable to connect to the new server. You need to ensure that the user is able to connect to the new server.
What should you do?

Your network consists of a single Active Directory domain. You have a domain controller and a member server that run Windows Server 2008 R2. Both servers are configured as DNS servers. Client computers run either Windows XP Service Pack 3 or Windows 7. You have a standard primary zone on the domain controller. The member server hosts a secondary copy of the zone.
You need to ensure that only authenticated users are allowed to update host (A) records in the DNS zone.
What should you do first?

Your network consists of a single Active Directory domain. The domain contains 10 domain controllers. The domain controllers run Windows Server 2008 R2 and are configured as DNS servers. You plan to create a new Active Directory-integrated zone. You need to ensure that the new zone is only replicated to four of your domain controllers.
What should you do first?

Your network consists of a single Active Directory domain. All domain controllers run Windows Server 2008 R2 and are configured as DNS servers. A domain controller named DC1 has a standard primary zone for contoso.com. A domain controller named DC2 has a standard secondary zone for contoso.com.
You need to ensure that the replication of the contoso.com zone is encrypted. You must not lose any zone data.
What should you do?

You have a domain controller named DC1 that runs Windows Server 2008 R2. DC1 is configured as a DNS server for contoso.com.
You install the DNS Server server role on a member server named Server1 and then you create a standard secondary zone for contoso.com. You configure DC1 as the master server for the zone. You need to ensure that Server1 receives zone updates from DC1.
What should you do?

Your network consists of an Active Directory forest that contains one domain. All domain controllers run Windows Server 2008 R2 and are configured as DNS servers. You have an Active Directory- integrated zone.
You have two Active Directory sites. Each site contains five domain controllers.
You add a new NS record to the zone.
You need to ensure that all domain controllers immediately receive the new NS record.
What should you do?

Your company has an Active Directory domain named ad.contoso.com. The domain has two domain controllers named DC1 and DC2. Both domain controllers have the DNS Server server role installed. You install a new DNS server named DNS1.contoso.com on the perimeter network. You configure DC1 to forward all unresolved name requests to DNS1.contoso.com. You discover that the DNS forwarding option is unavailable on DC2. You need to configure DNS forwarding on the DC2 server to point to the DNS1.contoso.com server. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

Contoso, Ltd. has an Active Directory domain named ad.contoso.com. Fabrikam, Inc. has an Active Directory domain named intranet.fabrikam.com.
Fabrikam’s security policy prohibits the transfer of internal DNS zone data outside the Fabrikam network.
You need to ensure that the Contoso users are able to resolve names from the intranet.fabrikam.com domain.
What should you do?

Your network consists of an Active Directory forest that contains one domain named contoso.com. All domain controllers run Windows Server 2008 R2 and are configured as DNS servers. You have two Active Directory-integrated zones: contoso.com and nwtraders.com. You need to ensure a user is able to modify records in the contoso.com zone. You must prevent the user from modifying the SOA record in the nwtraders.com zone.
What should you do?

Your network contains an Active Directory forest. All domain controllers run Windows Server 2008 R2 and are configured as DNS servers. You have an Active Directory-integrated zone for contoso.com.
You have a UNIX-based DNS server.
You need to configure your Windows Server 2008 R2 environment to allow zone transfers of the contoso.com zone to the UNIX-based DNS server.
