Q121. - (Topic 2)
You are developing an application that will read data from a text file and display the file contents.
You need to read data from the file, display it, and correctly release the file resources.
Which code segment should you use?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: A
Q122. - (Topic 1)
You are developing an application that includes the following code segment. (Line numbers are included for reference only.)
You need to ensure that the application accepts only integer input and prompts the user each time non-integer input is entered.
Which code segment should you add at line 19?
A. If (!int.TryParse(sLine, out number))
B. If ((number = Int32.Parse(sLine)) == Single.NaN)
C. If ((number = int.Parse(sLine)) > Int32.MaxValue)
D. If (Int32.TryParse(sLine, out number))
Answer: A
Explanation:
B and C will throw exception when user enters non-integer value. D is exactly the opposite what we want to achieve.
Int32.TryParse - Converts the string representation of a number to its 32-bit signed integer equivalent. A return value indicates whether the conversion succeeded. http://msdn.microsoft.com/en-us/library/f02979c7.aspx
Q123. - (Topic 2)
You are developing a method named GenerateHash that will create the hash value for a file. The method includes the following code. (Line numbers are included for reference only.)
You need to return the cryptographic hash of the bytes contained in the fileBuffer variable. Which code segment should you insert at line 05?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: D
Q124. - (Topic 1)
An application includes a class named Person. The Person class includes a method named GetData.
You need to ensure that the GetData() from the Person class.
Which access modifier should you use for the GetData() method?
A. Internal
B. Protected
C. Private
D. Protected internal
E. Public
Answer: B
Explanation:
Protected - The type or member can be accessed only by code in the same class or structure, or in a class that is derived from that class. http://msdn.microsoft.com/en-us/library/ms173121.aspx The protected keyword is a member access modifier. A protected member is accessible within its class and by derived class instances.
Q125. DRAG DROP - (Topic 2)
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:
You need to ensure that the application preserves the element ordering as provided in the XML stream.
You have the following code:
Which attributes should you include in Target 1, Target 2 and Target 3 to complete the code? (To answer, drag the appropriate attributes to the correct targets 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.)

Q126. - (Topic 1)
You are developing an application that includes the following code segment. (Line numbers are included for reference only.)
The GetAnimals() method must meet the following requirements:
Connect to a Microsoft SQL Server database.
Create Animal objects and populate them with data from the database.
Return a sequence of populated Animal objects.
You need to meet the requirements.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
A. Insert the following code segment at line 16: while(sqlDataReader.NextResult())
B. Insert the following code segment at line 13: sqlConnection.Open();
C. Insert the following code segment at line 13: sqlConnection.BeginTransaction();
D. Insert the following code segment at line 16: while(sqlDataReader.Read())
E. Insert the following code segment at line 16: while(sqlDataReader.GetValues())
Answer: B,D
Explanation:
SqlConnection.Open - Opens a database connection with the property settings specified by the ConnectionString. http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlconnection.open.aspx SqlDataReader.Read - Advances the SqlDataReader to the next record. http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqldatareader.read.aspx
Q127. - (Topic 1)
You are developing an application that will convert data into multiple output formats.
The application includes the following code. (Line numbers are included for reference only.)
You are developing a code segment that will produce tab-delimited output. All output routines implement the following interface:
You need to minimize the completion time of the GetOutput() method. Which code segment should you insert at line 06?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: B
Explanation:
A String object concatenation operation always creates a new object from the existing string and the new data. A StringBuilder object maintains a buffer to accommodate the concatenation of new data. New data is appended to the buffer if room is available; otherwise, a new, larger buffer is allocated, data from the original buffer is copied to the new buffer, and the new data is then appended to the new buffer. The performance of a concatenation operation for a String or StringBuilder object depends on the frequency of memory allocations. A String concatenation operation always allocates memory, whereas a StringBuilder concatenation operation allocates memory only if the StringBuilder object buffer is too small to accommodate the new data. Use the String class if you are concatenating a fixed number of String objects. In that case, the compiler may even combine individual concatenation operations into a single operation. Use a StringBuilder object if you are concatenating an arbitrary number of strings; for example, if you're using a loop to concatenate a random number of strings of user input.

Q128. 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.)

Q129. - (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.
Q130. DRAG DROP - (Topic 1)
You are developing a class named Temperature.
You need to ensure that collections of Temperature objects are sortable.
How should you complete the relevant code segment? (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.)
