You are creating a class named Data that includes a dictionary object named _data. 

You need to allow the garbage collection process to collect the references of the _data object. 

You have the following code: 

Which code segments should you include in Target 1 and Target 2 to complete the code? (To answer, drag the appropriate code segments to the correct locations in the answer area. Each code segment 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.)

Q113. - (Topic 1) 

You are creating a class named Game. 

The Game class must meet the following requirements: 

Include a member that represents the score for a Game instance. 

Allow external code to assign a value to the score member. 

Restrict the range of values that can be assigned to the score member. 

You need to implement the score member to meet the requirements. 

In which form should you implement the score member? 

A. protected field 

B. public static field 

C. public static property 

D. public property 

Answer: D 

Q114. - (Topic 2) 

You need to create a method that can be called by using a varying number of parameters. 

What should you use? 

A. Method overloading 

B. Interface 

C. Named parameters 

D. Lambda expressions 

Answer: A 

Explanation: 

Member overloading means creating two or more members on the same type that differ only in the number or type of parameters but have the same name. Overloading is one of the most important techniques for improving usability, productivity, and readability of reusable libraries. Overloading on the number of parameters makes it possible to provide simpler versions of constructors and methods. Overloading on the parameter type makes it possible to use the same member name for members performing identical operations on a selected set of different types. 

Q115. DRAG DROP - (Topic 2) 

You have a method that will evaluate a parameter of type Int32 named Status. You need to ensure that the method meets the following requirements: 

If Status is set to Active, the method must return 1. 

If Status is set to Inactive, the method must return 0. 

If Status is any other value, the method must return -1. 

What should you do? (To answer, drag the appropriate statement to the correct location 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.)

Which code should you use? 

A. Option A 

B. Option B 

C. Option C 

D. Option D 

Answer: D 

Explanation: Programmatically detecting Release/Debug mode (.NET) 

Boolean isDebugMode = false; 

#if DEBUG 

isDebugMode = true; 

#endif

Q117. - (Topic 2) 

You need to store the values in a collection. 

The solution must meet the following requirements: 

. The values must be stored in the order that they were added to the collection. . The values must be accessed in a first-in, first-out order. 

Which type of collection should you use? 

A. SortedList 

B. Queue 

C. ArrayList 

D. Hashtable 

Answer: B 

Q118. DRAG DROP - (Topic 2) 

You are developing an application that will write string values to a file. The application includes the following code segment. (Line numbers are included for reference only.) 

01 protected void ProcessFile(string fileName, string value) 02 { 

04 } 

You need to ensure that the ProcessFile() method will write string values to a file. 

Which four code segments should you insert in sequence at line 03? (To answer, move the appropriate code segments from the list of code segments to the answer area and arrange them in the correct order.) 

Answer: 

Q119. - (Topic 2) 

You are implementing a method named GetValidPhoneNumbers. The GetValidPhoneNumbers() method processes a list of string values that represent phone numbers. 

The GetValidPhoneNumbers() method must return only phone numbers that are in a valid format. 

You need to implement the GetValidPhoneNumbers() method. 

Which two code segments can you use 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,B 

Explanation: * Regex.Matches Searches an input string for all occurrences of a regular expression and returns all the matches. 

* MatchCollection 

Represents the set of successful matches found by iteratively applying a regular 

expression pattern to the input string. 

The collection is immutable (read-only) and has no public constructor. The Regex.Matches 

method returns a MatchCollection object. 

* List<T>.Add Method 

Adds an object to the end of the List<T>. 

Q120. - (Topic 1) 

You are debugging an application that calculates loan interest. The application includes the following code. (Line numbers are included for reference only.) 

You need to ensure that the debugger breaks execution within the CalculateInterest() method when the loanAmount variable is less than or equal to zero in all builds of the application. 

What should you do? 

A. Insert the following code segment at line 03: Trace.Assert(loanAmount > 0); 

B. Insert the following code segment at line 03: Debug.Assert(loanAmount > 0); 

C. Insert the following code segment at line 05: Debug.Write(loanAmount > 0); 

D. Insert the following code segment at line 05: Trace.Write(loanAmount > 0); 

Answer: A 

Explanation: 

By default, the Debug.Assert method works only in debug builds. Use the Trace.Assert method if you want to do assertions in release builds. For more information, see Assertions in Managed Code. http://msdn.microsoft.com/en-us/library/kssw4w7z.aspx
