You are developing the following classes named:
* Class1
* Class2
* Class3
All of the classes will be part of a single assembly named Assembly.dll. Assembly.dll will be used by multiple applications.
All of the classes will implement the following interface, which is also part ofAssembly.dll:
public interface Interface1
{
void Method1(decimal amount);
void Method2(decimal amount);
}
You need to ensure that the Method2 method for the Class3 class can be executed only when instances of the class are accessed through the Interface1 interface. The solution must ensure that calls to the Method1 method can be made either through the interface or through an instance of the class.
Which signature should you use for each method? (To answer, select the appropriate signature for each method in the answer area.)

An application receives JSON data in the following format:

The application includes the following code segment. (Line numbers are included for reference only.)

You need to ensure that the ConvertToName() method returns the JSON input string as a Name object.
Which code segment should you insert at line 10?

• A. Return (Name)ser.Serialize(json);
• B. Return ser.ConvertToType<Name>(json);
• C. Return ser.DeserializeObject(json);
• D. Return ser.Deserialize<Name>(json);

You are developing a method named GenerateHash that will create the hash value for a file. The method includes the following code. (Line numbers are included for reference only.)

You need to return the cryptographic hash of the bytes contained in the fileBuffer variable.
Which code segment should you insert at line 05?

• A. Option A
• B. Option C
• C. Option B
• D. Option D

You are implementing a method named ProcessData that performs a long-running task. The ProcessData() method has the following method signature:
public void ProcessData(List<decimal> values, CancellationTokenSource source, CancellationToken token) If the calling code requests cancellation, the method must perform the following actions:
Cancel the long-running task.
Set the task status to TaskStatus.Canceled.
You need to ensure that the ProcessData() method performs the required actions.
Which code segment should you use in the method body?

• A. source.Cancel();
• B. token.ThrowIfCancellationRequested();
• C. throw new AggregateException();
• D. if (token.IsCancellationRequested)
  return;
