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?

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.

You are required to dynamically load assemblies into a custom child application domain.
You need to ensure that the assemblies loaded into the child application domain have the same permissions as the applications that are accessed across the local intranet.
What should you do?

You work as the application developer at Domain.com. Domain.com uses Visual Studio.NET 2005 as its application development platform.
You use a Windwos XP Professional client computer named Certkiller -WS554 as your development computer.
You are developing a .NET Framework 2.0 application on a Certkiller -WS554.
The application will be used globally and must be able to represent characters in the following languages: English, Chinese Traditional, Hebrew and Tamil.
Your application is required to provide error detection for invalid sequences of characters whilst your application must also optimize storage.

You are developing a .NET Framework 2.0 banking Windows Forms application and are busy working on a function that retrieves the images of cancelled checks and displays them on the from. You currently have access to a method that reads the images from Microsoft SQL server as a series of bytes.
You are required to select a class that allows you to transfer the image from SQL Server to the Windows Forms application whilst your solution reduces the need of a temporary buffers and files

You use a Windwos XP Professional client computer named Certkiller -WS554 as your development computer.
You are developing a .NET Framework 2.0 application on Certkiller -WS554.
The application’s assembly is named Certkiller App and is stored in Certkiller App.exe.
You are busy using .NET Framework’s Strong Name tool to generate a pair for Certkiller App.exe shown below:
Sn.exe -k Certkiller AppKey
You are required to use the key pair to build the Certkiller App.exe as a strong named assembly.

You use a Windwos XP Professional client computer named Certkiller -WS554 as your development computer.
You are developing a .NET Framework 2.0 application on Certkiller -WS554.
You are trying to port an old Domain.com management application that was written in unmanaged Windows code with no COM interfaces.
The application you are developing makes calls to the old Domain.com management unmanaged library namedBillPerformance.dll.
You are required to make a call to the GetPerformaceScore method of the unmanaged Performance.dll library.

You work as the application developer at Domain.com. Domain.com uses Visual Studio.NET 2005 as its application development platform.
You are developing a .NET Framework 2.0 application that will be deployed throughout the network on all workstations which are all networked as part of a Microsoft Windows domain.
The application you wrote requires certain permissions in order to run.
As the domain administrator you configure the enterprise policy to grant the required permissions to the application which may be part of one or more code group.
You must ensure that your application receives the sufficient permissions to run at
all times whilst you override any policy changes made by the end users that lower the permissions required by the application to run.

You are developing a .NET Framework 2.0 application on Certkiller -WS536. The application will be used to send data over the internet.
You are required to ensure that the sent data is not modified or tampered with during transmission, the secrecy of the data transmission is not considered important.
You recently decided to implement a hash value for the data by using a secret key and transmit the data along with the hash value.
The receiver of the data should be able to detect whether the data or the hash value has been modified whilst the receiver should have access to the secret key that was used for computing the hash value.
You must additionally ensure that a key sequence of 160 bits should be acceptable.
