Q1. - (Topic 1)
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.
Answer: B,D
Q2. DRAG DROP - (Topic 2)
You have an application that accesses a Microsoft SQL Server database.
The database contains a stored procedure named Proc1. Proc1 accesses several rows of data across multiple tables.
You need to ensure that after Proc1 executes, the database is left in a consistent state. While Proc1 executes, no other operation can modify data already read or changed by Proc1. (Develop the solution by selecting and ordering the required code snippets.
You may not need all of the code snippets.)

Q3. - (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 have the following requirements:
. The debugger must break execution within the Calculatelnterest() method when the loanAmount variable is less than or equal to zero. . The release version of the code must not be impacted by any changes.
You need to meet the requirements.
What should you do?
A. Insert the following code segment at tine 05: Debug.Write(loanAmount > 0);
B. Insert the following code segment at line 05: Trace.Write(loanAmount > 0);
C. Insert the following code segment at line 03: Debug.Assert(loanAmount > 0);
D. Insert the following code segment at line 03: Trace.Assert(loanAmount > 0);
Answer: C
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
Q4. DRAG DROP - (Topic 1)
You are developing an application that implements a set of custom exception types. You declare the custom exception types by using the following code segments:
The application includes a function named DoWork that throws .NET Framework exceptions and custom exceptions. The application contains only the following logging methods:
The application must meet the following requirements:
. When ContosoValidationException exceptions are caught, log the information by using the static void Log (ContosoValidationException ex) method. . When ContosoDbException or other ContosoException exceptions are caught, log the information by using the static void Log(ContosoException ex) method.
You need to meet the requirements.
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.)

Q5. - (Topic 2)
You are developing a game that allows players to collect from 0 through 1000 coins. You are creating a method that will be used in the game. The method includes the following code. (Line numbers are included for reference only.)
01 public string FormatCoins(string name, int coins)
02 {
04 }
The method must meet the following requirements:
Return a string that includes the player name and the number of coins. Display the number of coins without leading zeros if the number is 1 or greater. Display the number of coins as a single 0 if the number is 0.
You need to ensure that the method meets the requirements.
Which code segment should you insert at line 03?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: D
Q6. - (Topic 2)
You are implementing a method named ProcessFile that retrieves data files from web servers and FTP servers. The ProcessFile () method has the following method signature:
Public void ProcessFile(Guid dataFileld, string dataFileUri)
Each time the ProcessFile() method is called, it must retrieve a unique data file and then save the data file to disk.
You need to complete the implementation of the ProcessFile() method. Which code segment should you use?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: D
Explanation: * WebRequest.Create Method (Uri)
Initializes a new WebRequest instance for the specified URI scheme.
* Example:
1. To request data from a host server
Create a WebRequest instance by calling Create with the URI of the resource.
C#
WebRequest request = WebRequest.Create("http://www.contoso.com/");
2. Set any property values that you need in the WebRequest. For example, to enable authentication, set the Credentials property to an instance of the NetworkCredential class.
C#
request.Credentials = CredentialCache.DefaultCredentials;
3. To send the request to the server, call GetResponse. The actual type of the returned WebResponse object is determined by the scheme of the requested URI.
C#
WebResponse response = request.GetResponse();
4. To get the stream containing response data sent by the server, use the GetResponseStream method of the WebResponse.
C#
Stream dataStream = response.GetResponseStream ();
Q7. DRAG DROP - (Topic 1)
An application serializes and deserializes XML from streams. The XML streams are in the following format:
The application reads the XML streams by using a DataContractSerializer object that is declared by the following code segment:
var ser = new DataContractSerializer(typeof(Name));
You need to ensure that the application preserves the element ordering as provided in the XML stream.
How should you complete the relevant code? (To answer, drag the appropriate attributes to the correct locations in the answer area-Each attribute 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:
Q8. - (Topic 2)
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<Customer> customersList = new List<Customer> () ;
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
Answer: A
Q9. - (Topic 2)
You are developing an application.
The application contains the following code:
When you compile the code, you receive the following syntax error message: "A previous catch clause already catches all exceptions of this or a super type ('System.Exception')."
You need to ensure that the code can be compiled. What should you do?

B. Throw a new exception in the second catch block.
C. Catch the ArgumentNullException exception first.
D. Re-throw the exception caught by the second catch block.

Q10. - (Topic 2)
You are developing an application by using C#. The application includes a method named SendMessage. The SendMessage() method requires a string input.
You need to replace "Hello" with "Goodbye" in the parameter that is passed to the SendMessage() 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: B,C
Explanation: * The first parameter should be Hello.
* String.Replace Method (String, String)
Returns a new string in which all occurrences of a specified string in the current instance are replaced with another specified string.
This method does not modify the value of the current instance. Instead, it returns a new string in which all occurrences of oldValue are replaced by newValue.
