You need to create a sender policy framework (SPF) record for the e-mail servers on your network.
Which type of resource record should you create?

Your network contains an Active Directory forest named fabrikam.com. The forest contains a DNS
server named Server1. You need to configure Server1 to resolve single-label names. What should
you do?

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.)

Your company has a single Active Directory forest that has six domains. All DNS servers in the forest
run Windows Server 2008 R2. You need to ensure that all public DNS queries are channeled through
a single-caching-only DNS server. Which two actions should you perform? (Each correct answer
presents part of the solution. Choose two.)

Contoso Ltd. has a single Active Directory forest that has five domains. Each domain has two DNS
servers. Each DNS server hosts Active Directory-integrated zones for all five domains. All domain
controllers run Windows Server 2008 R2. Contoso acquires a company named Tailspin Toys. Tailspin
Toys has a single Active Directory forest that contains a single domain. You need to configure the
DNS system in the Contoso forest to provide name resolution for resources in both forests. What
should you do?

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?

Your network contains an Active Directory domain named contoso.com. From DNS Manager, you
open the properties of contoso.com as shown in the exhibit. (Click the Exhibit button)

You need to ensure that you can modify the start of authority (SOA) record for contoso.com.
What should you do?

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?

Your company has a server named Server1 that runs a Server Core installation of Windows Server
2008 R2, and the DNS Server server role. Server1 has one network interface named Local Area
Connection. The static IP address of the network interface is configured as 10.0.0.1. You need to
create a DNS zone named local.contoso.com on Server1. Which command should you use?

Your network contains a server named Server1 that runs Windows Server 2008 R2. Server1 has the
Network_Policy Server (NPS) role installed. You need to ensure that the NPS log files on Server1
contain information of client connections. What should you do?
