If the application is compiled in Release mode, the console output must display Entering release
mode.
Which code should you use?

You need to ensure that the method extracts a list of URLs that match the following pattern:
@http://(www\\.)?([^\\.]+)\\.com;
Which code should you insert at line 07?

You are creating an application that reads from a database.
You need to use different databases during the development phase and the testing phase by using
conditional compilation techniques.
What should you do?

You are creating a console application named Appl.
App1 retrieves data from the Internet by using JavaScript Object Notation (JSON).
You are developing the following code segment (line numbers are included for reference only):

You need to ensure that the code validates the JSON string.
Which code should you insert at line 03?

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 CalculateInterest() 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 have a class named Customer and a variable named customers.
You need to test whether the customers’ variable is a generic list of Customer objects.
