You are developing an application that includes a class named Customer and a generic list
of customers. The following code segment declares the list of customers:
List<Customer> customersList = new List<Customer> () ;
You populate the customersList object with several hundred Customer objects.
The application must display the data for five Customer objects at a time.
You need to create a method that will return the correct number of Customer objects.
Which code segment should you use?

You are developing an application that will use multiple asynchronous tasks to optimize
performance.
You create three tasks by using the following code segment. (Line numbers are included for
reference only.)

You need to ensure that the ProcessTasks() method waits until all three tasks complete
before continuing.
Which code segment should you insert at line 09?

You are developing a C# application. The application includes the following code segment,
(Line numbers are included for reference only.)

The application fails at line 17 with the following error message: “An item with the same key
has already been added.”
You need to resolve the error.
Which code segment should you insert at line 16?

You are developing an application by using C#. The application includes a method named
SendMessage. The SendMessage() method requires a string input.
You need to replace “Hello” with “Goodbye” in the parameter that is passed to the
SendMessage() method.
Which two code segments can you use to achieve this goal? (Each correct answer presents
a complete solution. Choose two.)

You are developing an application that includes the following code segment:

You need to implement both Start() methods in a derived class named UseStart that uses
the Start() method of each interface.
Which two code segments should you use? (Each correct answer presents part of the
solution. Choose two.)

You need to write a console application that meets the following requirements:
If the application is compiled in Debug mode, the console output must display Entering
debug mode.
If the application is compiled in Release mode, the console output must display Entering
release mode.
Which code should you use?

You are developing an application by using C#. The application will write events to an event
log. You plan to deploy the application to a server.
You create an event source named AppSource and a custom log named AppLog on the server.
You need to write events to the custom log.
Which code segment should you use?

DRAG DROP
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.
How should you complete the relevant code? (To answer, drag the appropriate code
segments to the correct locations in the answer area. 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.)

You are implementing a method named ProcessFile that retrieves data files from web
servers and FTP servers. The ProcessFile () method has the following method signature:
Public void ProcessFile(Guid dataFileld, string dataFileUri)
Each time the ProcessFile() method is called, it must retrieve a unique data file and then
save the data file to disk.

You need to complete the implementation of the ProcessFile() method. Which code segment
should you use?

You are developing an application that will manage customer records. The application
includes a method named FindCustomer.

Users must be able to locate customer records by using the customer identifier or customer
name.
You need to implement the FindCustomer() method to meet the requirement.
Which two sets of method signatures can you use to achieve this goal? (Each correct
answer presents a complete solution. Choose two.)
