You are developing an application that will process orders. The debug and release versions of the
application will display different logo images.
You need to ensure that the correct image path is set based on the build configuration.
Which code segment should you use?

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.
The following code implements the methods. (Line numbers are included for reference only.)

You have the following requirements:
The Calculatelnterest() method must run for all build configurations.
The LogLine() method must run only for debug builds.
You need to ensure that the methods run correctly.
What are two possible ways to achieve this goal? (Each correct answer presents a complete solution.
Choose two.)

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 Counter2 is available for use in Windows Performance Monitor (PerfMon).
Which code segment should you insert at line 16?

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?

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 implementing a method named FloorTemperature 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 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?

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

DRAG DROP
You are developing an application that will include a method named GetDat
a. 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 entire 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.)
