Demo Questions

Question 1
You develop an application that displays information from log files when errors occur. The application will prompt the user to create an error report that sends details about the error and the session to the administrator. 
When a user opens a log file by using the application, the application throws an exception and closes. 
The application must preserve the original stack trace information when an exception occurs during this process. 
You need to implement the method that reads the log files. 
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 2
You are developing an application that includes a class named Kiosk. The Kiosk class includes a static property named Catalog. The Kiosk class is defined by the following code segment. (Line numbers are included for reference only.) 

  

You have the following requirements:
Initialize the _catalog field to a Catalog instance. 
Initialize the _catalog field only once. 
Ensure that the application code acquires a lock only when the _catalog object must be instantiated. 
You need to meet the requirements. 
Which three code segments should you insert in sequence at line 09? (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 3
You are developing an application that will include a method named GetData. The GetData() method will retrieve several lines of data from a web service by using a System.IO.StreamReader object. 
You have the following requirements:
The GetData() method must return a string value that contains the first line of the response from the web service. 
The application must remain responsive while the GetData() method runs. 
You need to implement the GetData() method. 
How should you complete the relevant code? (To answer, drag the appropriate objects to the correct locations in the answer area. Each object 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 4
You are adding a public method named UpdateScore to a public class named ScoreCard. 
The code region that updates the score field must meet the following requirements:
It must be accessed by only one thread at a time. 
It must not be vulnerable to a deadlock situation. 
You need to implement the UpdateScore() method. 
What should you do? 

  

  • A: Option A
  • B: Option B
  • C: Option C
  • D: Option D



Question 5
You are developing a C# application that has a requirement to validate some string input data by using the Regex class. 
The application includes a method named ContainsHyperlink. The ContainsHyperlink() method will verify the presence of a URI and surrounding markup. 
The following code segment defines the ContainsHyperlink() method. (Line numbers are included for reference only.) 

  

The expression patterns used for each validation function are constant. 
You need to ensure that the expression syntax is evaluated only once when the Regex object is initially instantiated. 
Which code segment should you insert at line 04?

  • A:
      
  • B:
      
  • C:
      
  • D:
      



Question 6
You are developing an application by using C#. 
You have the following requirements:
Support 32-bit and 64-bit system configurations. 
Include pre-processor directives that are specific to the system configuration. 
Deploy an application version that includes both system configurations to testers. 
Ensure that stack traces include accurate line numbers. 
You need to configure the project to avoid changing individual configuration settings every time you deploy the application to testers. 
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

  • A: Update the platform target and conditional compilation symbols for each application configuration.
  • B: Create two application configurations based on the default Release configuration.
  • C: Optimize the application through address rebasing in the 64-bit configuration.
  • D: Create two application configurations based on the default Debug configuration.



Question 7
You are developing a method named CreateCounters that will create performance counters for an application. 
The method includes the following code. (Line numbers are included for reference only.) 

 
 
You need to ensure that Counter1 is available for use in Windows Performance Monitor (PerfMon). 
Which code segment should you insert at line 16?

  • A: CounterType = PerformanccCounterType.RawBase
  • B: CounterType = PerformanceCounterType.AverageBase
  • C: CounterType = PerformanceCounterType.SampleBase
  • D: CounterType = PerformanceCounterType.CounterMultiBase



Question 8
You are developing an application that will transmit large amounts of data between a client computer and a server. 
You need to ensure the validity of the data by using a cryptographic hashing algorithm. 
Which algorithm should you use?

  • A: HMACSHA256
  • B: RNGCryptoServiceProvider
  • C: DES
  • D: Aes



Question 9
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. 
You have the following requirements:
The CalculateInterest() method must run for all build configurations. 
The LogLine() method must be called only for debug builds. 
You need to ensure that the methods run correctly. 
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 10
You are developing an assembly that will be used by multiple applications. 
You need to install the assembly in the Global Assembly Cache (GAC). 
Which two actions can you perform to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

  • A: Use the Assembly Registration tool (regasm.exe) to register the assembly and to copy the assembly to the GAC.
  • B: Use the Strong Name tool (sn.exe) to copy the assembly into the GAC.
  • C: Use Microsoft Register Server (regsvr32.exe) to add the assembly to the GAC.
  • D: Use the Global Assembly Cache tool (gacutil.exe) to add the assembly to the GAC.
  • E: Use Windows Installer 2.0 to add the assembly to the GAC.
