Your network contains a DNS server named DC1 that runs Windows Server 2008 R2. The network
uses a network ID of 10.1.1.0/24. You open the DNS console on Server1 as shown in the exhibit.
(Click the Exhibit button.)

You need to ensure that all client computers can resolve the IPv4 addresses of computers on the
network to fully qualified domain names (FQDNs). What should you do?

Your network contains a DNS server named Server1 that runs Windows Server 2008 R2.
Root hints for Server1 are configured as shown in the exhibit. (Click the Exhibit button.)

You need to add root hints to Server1. What should you do first?

Your network contains an Active Directory domain named contoso.com. The domain contains two
domain controllers named DC1 and DC2 that run Windows Server 2008 R2. DC1 hosts a primary zone
for contoso.com. DC2 hosts a secondary zone for contosto.com. You need to ensure that DNS zone
data is encrypted when the data replicates across the network. DC2 must provide authoritative
responses to client computers. What should you do?

Your network contains a DNS server named DNS1 that runs Windows Server 2008 R2. DNS1 hosts a
zone named contoso.com. Dynamic updates are enabled on the zone. The network contains a server
named Web1.contoso.com. All computers on the network are configured to use DNS1 as their DNS
server. You need to ensure that users can connect to Web1.contoso.com by using the name
portal.contoso.com. The solution must ensure that the users can connect by using
portal.contoso.com if the IP address of Web1.contoso.com changes. Which type of resource record
should you create?

Your network contains a DNS server named Server1 that runs Windows Server 2008 R2. You need to
ensure that client computers can resolve IPv6 addresses to fully qualified domain names (FQDNs).
Which type of resource record should you create?

Your company has a main office and a branch office. The network contains two DNS servers named
DNS1 and DNS2. DNS1 is located in the main office. DNS1 hosts a primary standard zone named
contoso.com. The contoso.com zone is configured to use DNSSEC. DNS2 is located in the branch
office. DNS2 is a caching-only DNS server. You need to ensure that client computers in the branch
office can receive authoritative responses to queries for contoso.com if a WAN link fails. DNSSEC
security must be maintained. What should you configure on DNS2 for contoso.com?

Your network contains an Active Directory domain named contoso.com. The domain contains two
sites named Site1 and Site2. The servers for the sites are configured as shown in the following table.

Server1 hosts a standard primary zone for contoso.com. Server2 hosts a secondary zone for
contoso.com. You need to ensure that all DNS replication traffic between Server1 and Server2 is
encrypted. What should you do?

Your network contains a single Active Directory domain named contoso.com. The domain contains a
DNS server named Server1 that hosts the contoso.com zone. The network is connected to the
network of a partner company. The partner company’s network contains a DNS server that hosts a
zone named nwtraders.com. You need to ensure that computers in contoso.com can resolve the
names of computers in nwtraders.com. The solution must not require any changes to the zone
configuration of nwtraders.com. What should you configure on Server1?

Your network contains an Active Directory forest. The forest contains three domain trees. Each
domain tree contains multiple domains. You have an Active Directory-integrated DNS zone. You
install a Web server named Web1. All of the users in the company will use Web1. You need to
ensure that the users can access Web1 by using the URL http://web1. You want to achieve this goal
by using the minimum amount of administrative effort. What should you do?

Your network contains an Active Directory forest. The forest contains two domains named
contoso.com and nwtraders.com. You have a DNS server named DNS1. DNS1 hosts Active Directoryintegrated zones for contoso.com and nwtraders.com. You discover that client computers in
contoso.com cannot use single-label names to access servers in nwtraders.com. You need to ensure
that contoso.com computers can access nwtraders.com servers by using singlelabel names. What
should you modify?
