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?

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?

You are creating a class named Employee. The class exposes a string property named EmployeeType.
The following code segment defines the Employee class. (Line numbers are included for reference
only.)

The EmployeeType property value must be accessed and modified only by code within the Employee
class or within a class derived from the Employee class.
You need to ensure that the implementation of the EmployeeType property meets the
requirements.
Which two actions should you perform? (Each correct answer represents part of the complete
solution. Choose two.)

You are implementing a method named Calculate that performs conversions between value types
and reference types. The following code segment implements the method. (Line numbers are
included for reference only.)

You need to ensure that the application does not throw exceptions on invalid conversions.
Which code segment should you insert at line 04?

You are creating a console application by using C#.
You need to access the application assembly.
Which code segment should you use?

HOTSPOT
You are implementing a library method that accepts a character parameter and returns a string.
If the lookup succeeds, the method must return the corresponding string value. If the lookup fails,
the method must return the value “invalid choice.”
You need to implement the lookup algorithm.
How should you complete the relevant code? (To answer, select the correct keyword in each dropdown list in the answer area.)

You use the Task.Run() method to launch a long-running data processing operation. The data
processing operation often fails in times of heavy network congestion.
If the data processing operation fails, a second operation must clean up any results of the first
operation.
You need to ensure that the second operation is invoked only if the data processing operation
throws an unhandled exception.
What should you do?

You are modifying an application that processes leases. The following code defines the Lease class.
(Line numbers are included for reference only.)

Leases are restricted to a maximum term of 5 years. The application must send a notification
message if a lease request exceeds 5 years.
You need to implement the notification mechanism.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose
two.)

You are developing an application that uses structured exception handling. The application includes
a class named ExceptionLogger.
The ExceptionLogger class implements a method named LogException by using the following code
segment:
public static void LogException(Exception ex)
You have the following requirements:
Log all exceptions by using the LogException() method of the ExceptionLogger class.
Rethrow the original exception, including the entire exception stack.
You need to meet the requirements.
Which code segment should you use?

You are developing an application that includes a class named UserTracker. The application includes
the following code segment. (Line numbers are included for reference only.)

You need to add a user to the UserTracker instance.
What should you do?
