You are troubleshooting an application that uses a class named FullName. The class is decorated with the
DataContractAttribute attribute. The application includes the following code. (Line numbers are included for
reference only.)

You need to ensure that the entire FullName object is serialized to the memory stream object.
Which code segment should you insert at line 09?

You are creating an application that reads from a database.
You need to use different databases during the development phase and the testing phase by using conditional
compilation techniques.
What should you do?

DRAG DROP
You are developing a C# console application that outputs information to the screen. The following code
segments implement the two classes responsible for making calls to the Console object:

When the application is run, the console output must be the following text:
Log started
Base: Log continuing
Finished
You need to ensure that the application outputs the correct text.
Which four lines of code should you use in sequence? (To answer, move the appropriate classes from the list
of classes to the answer area and arrange them in the correct order.)
Select and Place:

HOTSPOT
You define a class by using the following code:

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

You are implementing a method named GetValidEmailAddresses. The GetValidEmailAddresses() method
processes a list of string values that represent email addresses.
The GetValidEmailAddresses() method must return only email addresses that are in a valid format.
You need to implement the GetValidEmailAddresses() method.
Which two code segments can you use to achieve this goal? (Each correct answer presents a complete
solution. Choose two.)

You are modifying an existing banking application.
The application includes an Account class and a Customer class. The following code segment defines the
classes.

You populate a collection named customerCollection with Customer and Account objects by using the following
code segment:

You create a largeCustomerAccounts collection to store the Account objects by using the following code
segment:Collection<Account> largeCustomerAccounts = new Collection<Account> ();
All accounts with a Balance value greater than or equal to 1,000,000 must be tracked.
You need to populate the largeCustomerAccounts collection with Account objects.
Which code segment should you use?

You are developing an application that produces an executable named MyApp.exe and an assembly named
MyApp.dll.
The application will be sold to several customers.
You need to ensure that enough debugging information is available for MyApp.exe, so that if the application
throws an error in a customer’s environment, you can debug the error in your own development environment.
What should you do?

You are developing a class named EmployeeRoster. The following code implements the EmployeeRoster
class. (Line numbers are included for reference only.)

You create the following unit test method to test the EmployeeRoster class implementation:

You need to ensure that the unit test will pass.
What should you do?

You have an application that will send confidential information to a Web server.
You need to ensure that the data is encrypted when it is sent across the network.
Which class should you use?

You are developing a game that allows players to collect from 0 through 1000 coins. You are creating a method
that will be used in the game. The method includes the following code. (Line numbers are included for
reference only.)
01 public string FormatCoins(string name, int coins)
02 {
03
04 }
The method must meet the following requirements:
Return a string that includes the player name and the number of coins.
Display the number of coins without leading zeros if the number is 1 or greater.
Display the number of coins as a single 0 if the number is 0.
You need to ensure that the method meets the requirements.
Which code segment should you insert at line 03?
