DRAG DROP
You are developing an application that will write data to a file. The application includes the
following code segment. (Line numbers are included for reference only.)
You need to ensure that the WriteData() method will write data to a file.
Which four code segments should you insert in sequence at line 03? (To answer, move the
appropriate code segments from the list of code segments to the answer area and arrange
them in the correct order.)

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?

You are creating a class named Loan.
The Loan class must meet the following requirements:
Include a member that represents the rate for a Loan instance.
Allow external code to assign a value to the rate member.
Restrict the range of values that can be assigned to the rate member.
You need to implement the rate member to meet the requirements.
In which form should you implement the rate member?

You are creating a console application named App1.
App1 retrieves data from the Internet by using JavaScript Object Notation (JSON).
You are developing the following code segment (line numbers are included for reference only):

You need to ensure that the code validates the JSON string.
Which code should you insert at line 03?

You are developing an application that includes methods named EvaluateLoan,
ProcessLoan, and FundLoan. The application defines build configurations named TRIAL,
BASIC, and ADVANCED.
You have the following requirements:
The TRIAL build configuration must run only the EvaluateLoan() method.
The BASIC build configuration must run all three methods.
The ADVANCED build configuration must run only the EvaluateLoan() and ProcessLoan() methods.
You need to meet the requirements. Which code segment should you use?

You are creating an application that processes a list of numbers.
The application must define a method that queries the list and displays a subset of the
numbers to the user. The method must not update the list.
You need to create an extendable query by using LINQ.
What should you do?

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 order in which they are placed into the collection.
You need to meet the requirements.
What should you do?

You are debugging a 64-bit C# application.
Users report System.OutOfMemoryException exceptions. The system is attempting to use
arrays larger than 2 GB in size.
You need to ensure that the application can use arrays larger than 2 GB.
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.
Which code segment should you insert at line 23?

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.
