You are developing an application that includes a class named BookTracker for tracking library
books. The application includes the following code segment. (Line numbers are included for
reference only.)

You need to add a book to the BookTracker instance.
What should you do?

You use the Task.Run() method to launch a long-running data processing operation. The data
processing operation often fails in times of heavy network congestion.
If the data processing operation fails, a second operation must clean up any results of the first
operation.
You need to ensure that the second operation is invoked only if the data processing operation
throws an unhandled exception.
What should you do?

You are developing an application by using C#. You provide a public key to the development team
during development.
You need to specify that the assembly is not fully signed when it is built.
Which two assembly attributes should you include in the source code? (Each correct answer
presents part of the solution. Choose two.)

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 that uses the Microsoft ADO.NET Entity Framework to retrieve
order information from a Microsoft SQL Server database. The application includes the following
code. (Line numbers are included for reference only.)

The application must meet the following requirements:
Return only orders that have an OrderDate value other than null.
Return only orders that were placed in the year specified in the year parameter.
You need to ensure that the application meets the requirements. Which code segment should you
insert at line 08?

You are creating an application that manages information about your company’s products. The
application includes a class named Product and a method named Save.
The Save() method must be strongly typed. It must allow only types inherited from the Product class
that use a constructor that accepts no parameters.
You need to implement the Save() method.
Which code segment 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 meet the following requirements:
The value must be accessed only by code within the Employee class or within a class derived from
the Employee class.
The value must be modified only by code within 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 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 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?

DRAG DROP
You are developing an application by using C#. The application will process several objects per
second.
You need to create a performance counter to analyze the object processing.
Which three actions should you perform in sequence? (To answer, move the appropriate actions
from the list of actions to the answer area and arrange them in the correct order.)
