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?

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?

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.

You may not need all of the code snippets.)

HOTSPOT
You have the following code:

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

You have the following code:

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

HOTSPOT
You are reviewing the following code:

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

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.

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?

You are developing code for a class named Account. The Account class includes the following
method:

You need to ensure that overflow exceptions are thrown when there is an error.
Which type of block should you use?

You are developing an application that uses a .config file.
The relevant portion of the .config file is shown as follows:

You need to ensure that diagnostic data for the application writes to the event tog by using the
configuration specified in the .config file.
What should you include in the application code?
