You are developing an application that uses multiple asynchronous tasks to optimize performance.
The application will be deployed in a distributed environment.
You need to retrieve the result of an asynchronous task that retrieves data from a web service.
The data will later be parsed by a separate task.
Which code segment should you use?

You are implementing a method named GetValidPhoneNumbers. The GetValidPhoneNumbers()
method processes a list of string values that represent phone numbers.
The GetValidPhoneNumbers() method must return only phone numbers that are in a valid format.
You need to implement the GetValidPhoneNumbers() method.
Which two code segments can you use to achieve this goal? (Each correct answer presents a
complete solution. Choose two.)

You need to create a method that can be called by using a varying number of parameters.
What should you use?

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 class library that will be used in a web application.
You need to ensure that the class library assembly is strongly named.
What should you do?

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.
