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?

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.)

You are developing an application. The application calls a method that returns an array of
integers named customerIds. You define an integer variable named customerIdToRemove
and assign a value to it. You declare an array named filteredCustomerIds.
You have the following requirements.
Remove duplicate integers from the customerIds array.
Sort the array in order from the highest value to the lowest value.
Remove the integer value stored in the customerIdToRemove variable from the customerIds
array.
You need to create a LINQ query to meet the requirements.
Which code segment should you use?

You are developing a C# application that includes a class named Product. The following
code segment defines the Product class:

You implement System.ComponentModel.DataAnnotations.IValidateableObject interface to
provide a way to validate the Product object.
The Product object has the following requirements:
The Id property must have a value greater than zero.
The Name property must have a value other than empty or null.
You need to validate the Product object. Which code segment should you use?

DRAG DROP
You have the following class:

You need to implement IEquatable. The Equals method must return true if both ID and
Name are set to the identical values. Otherwise, the method must return false. Equals must
not throw an exception.
What should you do? (Develop the solution by selecting and ordering the required code
snippets. You may not need all of the code snippets.)

HOTSPOT
You are reviewing the following code:

For each of the following statements, select Yes if the statement is true. Otherwise, select No.

HOTSPOT
You have the following code:

To answer, complete each statement according to the information presented in the code.
