You need to declare a delegate for a method that accepts an integer as a parameter, and then returns an integer.
Which type of delegate should you use?
A. Action<int>
B. Action<int, int>
C. Func<int, int>

Q22. - (Topic 2)
You have the following code:
You need to retrieve all of the numbers from the items variable that are greater than 80. Which code should you use?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: A
Q23. - (Topic 1)
You are creating a console application by using C#.
You need to access the application assembly.
Which code segment should you use?
A. Assembly.GetAssembly(this);
B. this.GetType();
C. Assembly.Load();
D. Assembly.GetExecutingAssembly();
Answer: D
Explanation:
Assembly.GetExecutingAssembly - Gets the assembly that contains the code that is currently executing. http://msdn.microsoft.com/en-us/library/system.reflection.assembly.getexecutingassembly(v=vs.110).aspx
Assembly.GetAssembly - Gets the currently loaded assembly in which the specified class is defined. http://msdn.microsoft.com/en-us/library/system.reflection.assembly.getassembly.aspx
Q24. DRAG DROP - (Topic 2)
You create an assembly named Assembly1.dll.
You need to ensure that Assembly1.dll can be deployed to the global assembly cache (GAC).
Which commands should you run? (To answer, drag the appropriate programs to the correct locations. Each program may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)
Answer:
Q25. - (Topic 1)
You are testing an application. The application includes methods named CalculateInterest and LogLine. The CalculateInterest() method calculates loan interest. The LogLine() method sends diagnostic messages to a console window.
The following code implements the methods. (Line numbers are included for reference only.)
You have the following requirements:
. The Calculatelnterest() method must run for all build configurations. . The LogLine() method must run only for debug builds.
You need to ensure that the methods run correctly.
What are two possible ways to achieve this goal? (Each correct answer presents a complete solution. Choose two.)
A. Insert the following code segment at line 01:
#region DEBUG
Insert the following code segment at line 10:
#endregion
B. Insert the following code segment at line 10:
[Conditional(MDEBUG")]
C. Insert the following code segment at line 05:
#region DEBUG
Insert the following code segment at line 07:
#endregion
D. Insert the following code segment at line 01:
#if DE30G
Insert the following code segment at line 10:
#endif
E. Insert the following code segment at line 01:
[Conditional(MDEBUG")]
F. Insert the following code segment at line 05:
#if DEBUG
Insert the following code segment at line 07:
#endif
G. Insert the following code segment at line 10: [Conditional("RELEASE")]
Answer: B,F
Explanation:
#if DEBUG: The code in here won't even reach the IL on release. [Conditional("DEBUG")]: This code will reach the IL, however the calls to the method will not execute unless DEBUG is on. http://stackoverflow.com/questions/3788605/if-debug-vs-conditionaldebug
Q26. - (Topic 2)
You are developing an application that generates code. The application includes the following code segment. (Line numbers are included for reference only.)
You need to ensure that code generated by the GenerateCode() method represents a class that can be accessed by all objects in its application domain.
Which two code segments can you insert at line 05 to achieve this goal? (Each correct answer presents a complete solution. Choose two.)
A. Option A
B. Option B
C. Option C
D. Option D
Answer: A,C
Q27. DRAG DROP - (Topic 2)
You are adding a function to a membership tracking application- The function uses an integer named memberCode as an input parameter and returns the membership type as a string.
The function must meet the following requirements:
Return "Non-Member" if the memberCode is 0.
Return "Member" if the memberCode is 1.
Return "Invalid" if the memberCode is any value other than 0 or 1.
You need to implement the function to meet the requirements.
How should you complete the relevant code? (To answer, drag the appropriate statements to the correct locations in the answer area. Each statement may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)

Q28. - (Topic 2)
You have the following code. (Line numbers are included for reference only).
You need to complete the WriteTextAsync method. The solution must ensure that the code is not blocked while the file is being written.
Which code should you insert at line 12?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: D
Explanation: await sourceStream.WriteAsync(encodedText, 0, encodedText.Length);
The following example has the statement await sourceStream.WriteAsync(encodedText, 0,
encodedText.Length);, which is a contraction of the following two statements:
Task theTask = sourceStream.WriteAsync(encodedText, 0, encodedText.Length);
await theTask;
Example: The following example writes text to a file. At each await statement, the method immediately exits. When the file I/O is complete, the method resumes at the statement that follows the await statement. Note that the async modifier is in the definition of methods that use the await statement.
public async void ProcessWrite()
{
string filePath = @"temp2.txt";
string text = "Hello Worldrn";
await WriteTextAsync(filePath, text);
}
private async Task WriteTextAsync(string filePath, string text)
{
byte[] encodedText = Encoding.Unicode.GetBytes(text);
using (FileStream sourceStream = new FileStream(filePath,
FileMode.Append, FileAccess.Write, FileShare.None,
bufferSize: 4096, useAsync: true))
{
await sourceStream.WriteAsync(encodedText, 0, encodedText.Length);
};
}

Q29. DRAG DROP - (Topic 2)
You are creating a method that saves information to a database.
You have a static class named LogHelper. LogHelper has a method named Log to log the exception.
You need to use the LogHelper Log method to log the exception raised by the database server. The solution must ensure that the exception can be caught by the calling method, while preserving the original stack trace.
How should you write the catch block? (Develop the solution by selecting and ordering the required code snippets. You may not need all of the code snippets.)
