You are developing an application. The application includes a method named ReadFile that reads
data from a file.
The ReadFile() method must meet the following requirements:
It must not make changes to the data file.
It must allow other processes to access the data file.
It must not throw an exception if the application attempts to open a data file that does not exist.
You need to implement the ReadFile() method.
Which code segment should you use?

You are developing an application by using C#. The application includes an array of decimal values
named loanAmounts. You are developing a LINQ query to return the values from the array.
The query must return decimal values that are evenly divisible by two. The values must be sorted
from the lowest value to the highest value.
You need to ensure that the query correctly returns the decimal values.
How should you complete the relevant code? (To answer, drag the appropriate code segments to
the correct locations in the answer are
a. 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.)

An application receives JSON data in the following format:

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

You need to ensure that the ConvertToName() method returns the JSON input string as a Name
object.
Which code segment should you insert at line 10?

You are developing an application. The application converts a Location object to a string by using a
method named WriteObject. The WriteObject() method accepts two parameters, a Location object
and an XmlObjectSerializer object.
The application includes the following code. (Line numbers are included for reference only.)

You need to serialize the Location object as a JSON object.
Which code segment should you insert at line 20?

DRAG DROP
An application serializes and deserializes XML from streams. The XML streams are in the following
format:

The application reads the XML streams by using a DataContractSerializer object that is declared by
the following code segment:
var ser = new DataContractSerializer(typeof(Name));
You need to ensure that the application preserves the element ordering as provided in the XML
stream.
How should you complete the relevant code? (To answer, drag the appropriate attributes to the
correct locations in the answer area-Each attribute 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.)

An application includes a class named Person. The Person class includes a method named GetData.
You need to ensure that the GetData() from the Person class.
Which access modifier should you use for the GetData() method?

You are developing an application by using C#. The application includes the following code segment.
(Line numbers are included for reference only.)

The DoWork() method must not throw any exceptions when converting the obj object to the
IDataContainer interface or when accessing the Data property.
You need to meet the requirements. Which code segment should you insert at line 07?

You are creating an application that manages information about zoo animals. The application
includes a class named Animal and a method named Save.
The Save() method must be strongly typed. It must allow only types inherited from the Animal class
that uses a constructor that accepts no parameters.
You need to implement the Save() method.
Which code segment should you use?

You are developing an application. The application includes classes named Employee and Person and
an interface named IPerson.
The Employee class must meet the following requirements:
It must either inherit from the Person class or implement the IPerson interface.
It must be inheritable by other classes in the application.
You need to ensure that the Employee class meets the requirements.
Which two code segments can you use to achieve this goal? (Each correct answer presents a
complete solution. Choose two.)

DRAG DROP
You are developing a class named ExtensionMethods.
You need to ensure that the ExtensionMethods class implements the IsEmail() method on string
objects.
How should you complete the relevant code? (To answer, drag the appropriate code segments to
the correct locations in the answer are
a. 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.)
