Microsoft 70-483 Online Questions & Answers

• Question 161:

  You are developing an application by using C#.

  The application includes an object that performs a long running process.

  You need to ensure that the garbage collector does not release the object's resources until the process completes.

  Which garbage collector method should you use?

  A. WaitForFullGCComplete()
  B. SuppressFinalize()
  C. collect()
  D. RemoveMemoryPressure()
  B. SuppressFinalize()

  ---

  You can use the SuppressFinalize method in a resource class to prevent a redundant garbage collection from being called. Reference: GC.SuppressFinalize Method (Object) https://msdn.microsoft.com/en-us/library/system.gc.suppressfinalize(v=vs.110).aspx

• Question 162:

  DRAG DROP

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

  You need to ensure that the WriteData() method will write data 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.)

• Question 163:

  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
  A. Option A
  B. Option B

  *

  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.Add Method

  Adds an object to the end of the List.

• Question 164:

  DRAG DROP

  You are developing an application by using C#. The application includes an array of decimal values named loanAmounts. You are developing a LINQ query to return the values from the array.

  The query must return decimal values that are evenly divisible by two. The values must be sorted from the lowest value to the highest value.

  You need to ensure that the query correctly returns the decimal values.

  How should you complete the relevant 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.)

• Question 165:

  HOTSPOT

  You have an existing order processing system that accepts .xml files,

  The following code shows an example of a properly formatted order in XML:

  

  You create the following class that will be serialized:

  

  For each of the following properties, select Yes if the property is serialized according to the defined schema. Otherwise, select No.

  Hot Area:

  

  

• Question 166:

  You are developing an application that includes a class named Customer and a generic list of customers. The following code segment declares the list of customers:

  List customersList = new List () ;

  You populate the customersList object with several hundred Customer objects.

  The application must display the data for five Customer objects at a time.

  You need to create a method that will return the correct number of Customer objects.

  Which code segment should you use?

  

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

  Note: Something wrong with question as the question is about LINQ, while the answers are about class definitions (and not LINQ method definitions).

• Question 167:

  You are developing an application. The application calls a method that returns an array of integers named employeeIds. You define an integer variable named employeeIdToRemove and assign a value to it. You declare an array named

  filteredEmployeeIds.

  You have the following requirements:

  Remove duplicate integers from the employeeIds array. Sort the array in order from the highest value to the lowest value. Remove the integer value stored in the employeeIdToRemove variable from the employeeIds array.

  You need to create a LINQ query to meet the requirements.

  Which code segment should you use?

  

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

  ---

  The Distinct keyword avoids duplicates, and OrderByDescending provides the proper ordering from highest to lowest.

• Question 168:

  DRAG DROP

  You are developing a C# console application that outputs information to the screen. The following code segments implement the two classes responsible for making calls to the Console object:

  

  When the application is run, the console output must be the following text:

  Log started

  Base: Log continuing

  Finished

  You need to ensure that the application outputs the correct text.

  Which four lines of code should you use in sequence? (To answer, move the appropriate classes from the list of classes to the answer area and arrange them in the correct order.)

  Select and Place:

  

  

• Question 169:

  You are creating an application that reads from a database.

  You need to use different databases during the development phase and the testing phase by using conditional compilation techniques. What should you do?

  A. Configure the assembly metadata to use the pre-existing public key for the assembly identity by using the AssemblySignatureKeyAttribute attribute.
  B. Disable the strong-name bypass feature of Microsoft .NET Framework in the registry.
  C. Configure the Define DEBUG constant setting in Microsoft Visual Studio.
  D. Decorate the code by using the [assembly:AssemblyDelaySignAttribute(true)] attribute.
  C. Configure the Define DEBUG constant setting in Microsoft Visual Studio.

  ---

  Use one debug version to connect to the development database, and a standard version to connect to the live database.

• Question 170:

  You have an assembly named Assembly named Assembly1 that is written in C#.

  Your company plans to sell Assembly =1 to customers. The customers might debug Assembly1.

  You need to minimize the amount of information contained within the debug symbols that are shipped with Assembly1.

  How should you create the debug symbols for Assembly1?

  A. Create a new PDB file by running pdbcopy.exe.
  B. Build Assembly1 by using a Debug configuration.
  C. On the Build page of the project properties for Assembly1, click Define TRACE constant and clear Define DEBUG constant.
  D. Build Assembly1 by using a Release configuration.
  C. On the Build page of the project properties for Assembly1, click Define TRACE constant and clear Define DEBUG constant.
