You are developing an application that will populate an extensive XML tree from a Microsoft
SQL Server 2008 R2 database table named Contacts.
You are creating the XML tree. The solution must meet the following requirements:
Minimize memory requirements.
Maximize data processing speed.
You open the database connection.
You need to create the XML tree.
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.)

DRAG DROP
You are creating a class named Data that includes a dictionary object named _data.
You need to allow the garbage collection process to collect the references of the _data
object.
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

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 uses several objects. The application includes the
following code segment. (Line numbers are included for reference only.)

You need to evaluate whether an object is null.
Which code segment should you insert at line 03?

You are developing an application.
The application contains the following code segment (line numbers are included for
reference only):

When you run the code, you receive the following error message: “Cannot implicitly convert
type ‘object” to ‘int’. An explicit conversion exists (are you missing a cast?).”
You need to ensure that the code can be compiled. Which code should you use to replace
line 05?

You need to write a method that retrieves data from a Microsoft Access 2013 database. The
method must meet the following requirements:
Be read-only.
Be able to use the data before the entire data set is retrieved.
Minimize the amount of system overhead and the amount of memory usage.
Which type of object should you use in the method?

You have the following code:

You need to retrieve all of the numbers from the items variable that are greater than 80.
Which code should you use?

DRAG DROP

You are adding a function to a membership tracking application- The function uses an
integer named memberCode as an input parameter and returns the membership type as a
string.
The function must meet the following requirements:
Return “Non-Member” if the memberCode is 0.
Return “Member” if the memberCode is 1.
Return “Invalid” if the memberCode is any value other than 0 or 1.
You need to implement the function to meet the requirements.
How should you complete the relevant code? (To answer, drag the appropriate statements
to the correct locations in the answer area. Each statement 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.)

HOTSPOT
You are developing the following classes named:
Class1
Class2
Class3
All of the classes will be part of a single assembly named Assembly.dll. Assembly.dll will be
used by multiple applications.
All of the classes will implement the following interface, which is also part ofAssembly.dll:
<code>
public interface Interface1
{
void Method1(decimal amount);
void Method2(decimal amount);
}
</code>
You need to ensure that the Method2 method for the Class3 class can be executed only
when instances of the class are accessed through the Interface1 interface. The solution
must ensure that calls to the Method1 method can be made either through the interface or
through an instance of the class.
Which signature should you use for each method? (To answer, select the appropriate
signature for each method in the answer area.)

DRAG DROP
You are creating a method that will split a single input file into two smaller output files.
The method must perform the following actions:
Create a file named header.dat that contains the first 20 bytes of the input file.
Create a file named body.dat that contains the remainder of the input file.
You need to create the method.
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
