DRAG DROP 
You are developing an application that will include a method named GetData. The GetData() method will retrieve several lines of data from a web service by using a System.IO.StreamReader object. 
You have the following requirements: 
• The GetData() method must return a string value that contains the first line of the response from the web service. 
• The application must remain responsive while the GetData() method runs. 
You need to implement the GetData() method. 
How should you complete the relevant code? (To answer, drag the appropriate objects to the correct locations in the answer area. Each object 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.) 



Answer: 




You are implementing a method named Calculate that performs conversions between value types and reference types. 
The following code segment implements the method. (Line numbers are included for reference only.) 



You need to ensure that the application does not throw exceptions on invalid conversions. 
Which code segment should you insert at line 04? 
A. int balance = (int) (float)amountRef; 
B. int balance = (int)amountRef; 
C. int balance = amountRef; 
D. int balance = (int) (double) amountRef; 
Answer: A

You are developing a C# application that has a requirement to validate some string input data by using the Regex class. The application includes a method named ContainsHyperlink. The ContainsHyperlink() method will verify the presence of a URI and surrounding markup. 
The following code segment defines the ContainsHyperlink() method. (Line numbers are included for reference only.) 



The expression patterns used for each validation function are constant. You need to ensure that the expression syntax is evaluated only once when the Regex object is initially instantiated. 
Which code segment should you insert at line 04? 



A. Option A 
B. Option B 
C. Option C 
D. Option D 
Answer: D 


You are developing an application. The application calls a method that returns an array of integers named employeeIds. You define an integer variable named employeeIdToRemove and assign a value to it. You declare an array named filteredEmployeeIds. 
You have the following requirements: 
• Remove duplicate integers from the employeeIds array. 
• Sort the array in order from the highest value to the lowest value. 
• Remove the integer value stored in the employeeIdToRemove variable from the employeeIds array. 
You need to create a LINQ query to meet the requirements. 
Which code segment should you use? 



A. Option A 
B. Option B 
C. Option C 
D. Option D 
Answer: C

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.) 



A. Option A 
B. Option B 
C. Option C 
D. Option D 
Answer: B, D 


You are developing a method named CreateCounters that will create performance counters for an application. 
The method includes the following code. (Line numbers are included for reference only.) 



You need to ensure that Counter1 is available for use in Windows Performance Monitor (PerfMon). 
Which code segment should you insert at line 16? 
A. CounterType = PerformanccCounterType.RawBase 
B. CounterType = PerformanceCounterType.AverageBase 
C. CounterType = PerformanceCounterType.SampleBase 
D. CounterType = PerformanceCounterType.CounterMultiBase 
Answer: C 


You are modifying an application that processes leases. 
The following code defines the Lease class. (Line numbers are included for reference only.) 



Leases are restricted to a maximum term of 5 years. The application must send a notification message if a lease request exceeds 5 years. You need to implement the notification mechanism. 
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.) 



A. Option A 
B. Option B 
C. Option C 
D. Option D 
E. Option E 
F. Option F 
Answer: A, B

DRAG DROP 
You are developing an application that includes a class named Kiosk. The Kiosk class includes a static property named Catalog. 
The Kiosk class is defined by the following code segment. (Line numbers are included for reference only.) 



You have the following requirements: 
• Initialize the _catalog field to a Catalog instance. 
• Initialize the _catalog field only once. 
• Ensure that the application code acquires a lock only when the _catalog object must be instantiated. 
You need to meet the requirements. 
Which three code segments should you insert in sequence at line 09? (To answer, move the appropriate code segments from the list of code segments to the answer area and arrange them in the correct order.) 



Answer: 





DRAG DROP 
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 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.) 



Answer:
