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 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 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 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 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.)

HOTSPOT
You define a class by using the following code:

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

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 need to write a method that retrieves data from a Microsoft Access 2013 database. The method
must meet the following requirements:
Be read-only.
Be able to use the data before the entire data set is retrieved.
Minimize the amount of system overhead and the amount of memory usage.
Which type of object should you use in the method?
