An application includes a class named Person. The Person class includes a method named
GetData.
You need to ensure that the GetData() method can be used only by the Person class or a
class derived from the Person class.
Which access modifier should you use for the GetData() method?

You are developing an application by using C#. The application includes the following code
segment. (Line numbers are included for reference only.)

The DoWork() method must not throw any exceptions when converting the obj object to the
IDataContainer interface or when accessing the Data property.
You need to meet the requirements. Which code segment should you insert at line 07?

You are creating an application that manages information about zoo animals. The
application includes a class named Animal and a method named Save.
The Save() method must be strongly typed. It must allow only types inherited from the
Animal class that uses a constructor that accepts no parameters.
You need to implement the Save() method.
Which code segment should you use?

DRAG DROP
You are developing a class named ExtensionMethods
You need to ensure that the ExtensionMethods class implements the IsUrl() method on
string objects.
How should you complete the relevant code? (To answer, drag the appropriate code
segments to the correct locations in the answer area. 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. The application includes classes named Employee and
Person and an interface named IPerson.
The Employee class must meet the following requirements:
It must either inherit from the Person class or implement the IPerson interface.
It must be inheritable by other classes in the application.
You need to ensure that the Employee class meets the requirements.
Which two code segments can you use to achieve this goal? (Each correct answer presents
a complete solution. Choose two.)

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?
