You need to retrieve the result of an asynchronous task.
Which code segment should you use?

You are developing an application.
The application contains the following code:

When you compile the code, you receive the following syntax error message: “A previous catch
clause already catches all exceptions of this or a super type (‘System.Exception’).”
You need to ensure that the code can be compiled. What should you do?

You are developing an application that includes a method named SendMessage.
You need to ensure that the SendMessage() method is called with the required parameters.
Which two code segments can you use to achieve this goal? (Each correct answer presents a
complete solution. Choose two.)

You have an application that accesses a Web server named Server1.
You need to download an image named Imagel.jpg from Server1 and store the image locally as
Filel.jpg.
Which code should you use?

You are developing a C# application. The application references and calls a RESTful web service
named EmployeeService. The EmployeeService web service includes a method named GetEmployee,
which accepts an employee ID as a parameter. The web service returns the following JSON data from
the method.
{“Id”:1,”Name”:”David Jones”>
The following code segment invokes the service and stores the result:

You need to convert the returned JSON data to an Employee object for use in the application.
Which code segment should you use?

You are developing an assembly.
You plan to sign the assembly when the assembly is developed.
You need to reserve space in the assembly for the signature.
What should you do?

You have the following code (line numbers are included for reference only):

You need to ensure that if an exception occurs, the exception will be logged.
Which code should you insert at line 28?

You are troubleshooting an application that uses a class named FullName. The class is decorated
with the DataContractAttribute attribute. The application includes the following code. (Line numbers
are included for reference only.)

You need to ensure that the entire FullName object is serialized to the memory stream object.
Which code segment should you insert at line 09?

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?
