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 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 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.

HOTSPOT
You have the following code:

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

DRAG DROP
You have a method named GetCustomerIDs that returns a list of integers. Each entry in the list
represents a customer ID that is retrieved from a list named Customers. The Customers list contains
1,000 rows.
Another developer creates a method named ValidateCustomer that accepts an integer parameter
and returns a Boolean value. ValidateCustomer returns true if the integer provided references a
valid customer. ValidateCustomer can take up to one second to run.
You need to create a method that returns a list of valid customer IDs. The code must execute in the
shortest amount of time.
What should you do? (Develop the solution by selecting and ordering the required code snippets.
You may not need all of the code snippets.)

You are creating a class named Game.
The Game class must meet the following requirements:
Include a member that represents the score for a Game instance.
Allow external code to assign a value to the score member.
Restrict the range of values that can be assigned to the score member.
You need to implement the score member to meet the requirements.
In which form should you implement the score member?

You have a List object that is generated by executing the following code:

You have a method that contains the following code (line numbers are included for reference only):

You need to alter the method to use a lambda statement.
How should you rewrite lines 03 through 06 of the method?
