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.
What should you do?

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.)
