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 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?

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 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 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 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 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 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 evaluating a method that calculates loan interest. The application includes the following code segment.
(Line numbers are included for reference only.)

When the loanTerm value is 5 and the loanAmount value is 4500, the loanRate must be set to 6.5 percent.
You need to adjust the loanRate value to meet the requirements.
What should you do?

You develop an application by using C#. The application counts the number of times a specific word appears
within a set of text files. The application includes the following code. (Line numbers are included for reference
only.)

You have the following requirements:
Populate the _wordCounts object with a list of words and the number of occurrences of each word.
Ensure that updates to the ConcurrentDictionary object can happen in parallel.
You need to complete the relevant code.
