What should you do?
You are currently in the process of developing a business logic component that requires long calculations.
You have identified numerous tasks within this application that can be done asynchronously.
You notice that these tasks are mutually dependent and require complex synchronization techniques so that it can manage efficiently.
You decide to use Microsoft .NET 2.0 to take advantage of its new thread management features.
You need to create and start the application threads.

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.

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.

Which two actions should you perform?
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.)
Choose the code segment which you should use.
You work as the application developer at Domain.com.
You are developing a new application named Certkiller App06.
Certkiller App06 will be used to transmit confidential financial information over the network.
To secure the confidential data, you create an X509 Certificate object named certificate and create a TcpClient object named client.
You must now create the code segment that creates an SslStream for communication by applying the Transport Layer Security 1.0 protocol.
Choose the code segment which you should use.
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.root-servers.net. The server must be able to resolve names for Internet hosts.

Choose the code segment that will do this.
You work as the application developer at Domain.com.
You are writing a method that will run through the credentials of the end user. Microsoft Windows groups must be used to authorize the user.
You must develop the code segment which will recognize if the user exists in the local group named Sales.
Choose the code segment that will do this.
What should you do?
Your network consists of a single Active Directory domain. The domain contains a server named Server1 that runs Windows Server 2008 R2. All client computers run Windows 7. All computers are members of the Active Directory domain.
You assign the Secure Server (Require Security) IPsec policy to Server1 by using a Group Policy object (GPO).
Users report that they fail to connect to Server1.
You need to ensure that users can connect to Server1. All connections to Server1 must be encrypted.
