Q112. 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.)

Q114. - (Topic 1)
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. Option A
B. Option B
C. Option C
D. Option D
Answer: D
Explanation:
RegexOptions.Compiled - Specifies that the regular expression is compiled to an assembly.This yields faster execution but increases startup time.This value should not be assigned to the Options property when calling the CompileToAssembly method. http://msdn.microsoft.com/en-us/library/system.text.regularexpressions.regexoptions.aspx Additional info http://stackoverflow.com/questions/513412/how-does-regexoptions-compiled-work
Q115. DRAG DROP - (Topic 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.)

You are developing an application for a bank. The application includes a method named ProcessLoan that processes loan applications. The ProcessLoan() method uses a method named CalculateInterest. The application includes the following code:
You need to declare a delegate to support the ProcessLoan() method. Which code segment should you use?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: C
Q117. - (Topic 1)
You are developing an application that includes a class named Order. The application will store a collection of Order objects.
The collection must meet the following requirements:
Use strongly typed members.
Process Order objects in first-in-first-out order.
Store values for each Order object.
. Use zero-based indices.
You need to use a collection type that meets the requirements.
Which collection type should you use?
A. Queue<T>
B. SortedList
C. LinkedList<T>
D. HashTable
E. Array<T>
Answer: A
Explanation:
Queues are useful for storing messages in the order they were received for sequential processing. Objects stored in a Queue<T> are inserted at one end and removed from the other. http://msdn.microsoft.com/en-us/library/7977ey2c.aspx
