You are developing a C# application. The application includes a class named Rate. The following code
segment implements the Rate class:

You define a collection of rates named rateCollection by using the following code segment:
Collection<Rate> rateCollection = new Collection<Rate>() ;
The application receives an XML file that contains rate information in the following format:

You need to parse the XML file and populate the rateCollection collection with Rate objects.
You have the following code:

Which code segments should you include in Target 1, Target 2, Target 3 and Target 4 to complete
the code? (To answer, drag the appropriate code segments to the correct targets in the answer are
a Each code segment may be used once, more than once, or not at all. You may need to drag the
split bar between panes or scroll to view content.)

split bar between panes or scroll to view content.

You have the following code:

You need to retrieve all of the numbers from the items variable that are greater than 80.
Which code should you use?

You have the following code. (Line numbers are included for reference only).

You need to complete the WriteTextAsync method. The solution must ensure that the code is not
blocked while the file is being written.

DRAG DROP
An application serializes and deserializes XML from streams. The XML streams are in the following
format:

The application reads the XML streams by using a DataContractSerializer object that is declared by
the following code segment:

You need to ensure that the application preserves the element ordering as provided in the XML
stream.

You have the following code:
Which attributes should you include in Target 1, Target 2 and Target 3 to complete the code? (To
answer, drag the appropriate attributes to the correct targets in the answer are
a Each attribute may be used once, more than once, or not at all. You may need to drag the split bar

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?

You are developing an application that contains a class named TheaterCustomer and a method
named ProcessTheaterCustomer. The ProcessTheaterCustomer() method accepts a
TheaterCustomer object as the input parameter.
You have the following requirements:
Store the TheaterCustomer objects in a collection.
Ensure that the ProcessTheaterCustomer() method processes the TheaterCustomer objects in the
reverse order in which they are placed into the collection.
You need to meet the requirements.
What should you do?

You have the following code (line numbers are included for reference only):

You need to ensure that new instances of Connection can be created only by other classes by calling
the Create method. The solution must allow classes to inherit from Connection.
What should you do?
