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.
You have the following code:

Which code segments should you include in Target 1, Target 2 and Target 3 to complete the code?
(To answer, drag the appropriate code segments to the correct targets 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 write the following method (line numbers are included for reference only):

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 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.
Which line of code should you use?
