Which two actions should you perform?
Your company uses Active Directory-integrated DNS. Users require access to the Internet. You run a
network capture. You notice the DNS server is sending DNS name resolution queries to a server
named f.root-servers.net. You need to prevent the DNS server from sending queries to f.rootservers.net. The server must be able to resolve names for Internet hosts. Which two actions should
you perform? (Each correct answer presents part of the solution. Choose two.)
You need to ensure that the stale resource records are removed from na.contoso.com
Your company has a single Active Directory forest that has an Active Directory domain named
na.contoso.com. A server named Server1 runs the DNS Server server role. You notice stale resource
records in the na.contoso.com zone. You have enabled DNS scavenging on Server1. Three weeks
later, you notice that the stale resource records remain in na.contoso.com. You need to ensure that
the stale resource records are removed from na.contoso.com. What should you do?
You need to ensure that Server3 is able to immediately resolve the updated DNS record
Your company has two servers that run Windows Server 2008 R2 named Server2 and Server3. Both
servers have the DNS Server server role installed. Server3 is configured to forward all DNS requests
to Server2. You update a DNS record on Server2. You need to ensure that Server3 is able to
immediately resolve the updated DNS record. What should you do?
You need to restore name resolution in the branch office
Your company has a main office and a branch office. The company network has two WINS servers.
You have an application that requires NetBIOS name resolution. The WINS servers are configured as
shown in the following table.
You discover that the WINS addresses on all client computers in both offices are configured in the
following order of use:
10.1.0.23
10.6.0.254
You reconfigure the WINS addresses on all client computers in the branch office in the following
order of use:
10.6.0.254
10.1.0.23
After the reconfiguration, users in the branch office are unable to connect to the servers that are
located in the main office. You need to restore name resolution in the branch office. What should
you do?
You need to ensure name resolution for users in contoso.com to resources in partner.com
Your company has a single domain named contoso.com. The contoso.com DNS zone is Active
Directoryintegrated. Your partner company has a single domain named partner.com. The
partner.com DNS zone is Active Directoryintegrated. The IP addresses of the DNS servers in the
partner domain will change. You need to ensure name resolution for users in contoso.com to
resources in partner.com. What should you do?
Which tool should you use?
Your network contains a server that runs a Server Core installation of Windows Server 2008 R2. You
need to configure outbound firewall rules on the server. Which tool should you use?
You need to ensure that the DNS server in the branch office is able to query any DNS server in the main office
Your company has multiple DNS servers in the main office. You plan to install DNS on a member
server in a branch office. You need to ensure that the DNS server in the branch office is able to query
any DNS server in the main office, and you need to limit the number of DNS records that are
transferred to the DNS server in the branch office. What should you do?
You need to minimize DNS zone transfer traffic over the WAN links
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?
You need to ensure that users in the branch offices can access their local application server even if the WAN
Your company has a main office and two branch offices. Domain controllers in the main office host
an Active Directory-integrated zone. The DNS servers in the branch offices host a secondary zone for
the domain and use the main office DNS servers as the DNS Master servers for the zone. Each
branch office has an application server. Users access the application server by using its fully qualified
domain name. You need to ensure that users in the branch offices can access their local application
server even if the WAN links are down for three days. What should you do?
You need to ensure that the contoso.com zone is available on Server2
Your network contains two servers named Server1 and Server2 that run Windows Server 2008 R2.
Server1 and Server2 are configured as DNS servers. On Server1, you create a primary DNS zone
named contoso.com. You configure Server2 to host a secondary copy of contoso.com. On Server2,
you open DNS Manager as shown in the exhibit. (Click the Exhibit button.)
You need to ensure that the contoso.com zone is available on Server2. What should you do?
