Q71. - (Topic 2)
You are developing an application that retrieves patient data from a web service. The application stores the JSON messages returned from the web service in a string variable named PatientAsJson. The variable is encoded as UTF-8. The application includes a class named Patient that is defined by the following code:
You need to populate the Patient class with the data returned from the web service. Which code segment should you use?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: A
Q72. - (Topic 2)
You need to create a method that can be called by using a varying number of parameters.
What should you use?
A. derived classes
B. interface
C. enumeration
D. method overloading
Answer: D
Explanation: Member overloading means creating two or more members on the same type that differ only in the number or type of parameters but have the same name. Overloading is one of the most important techniques for improving usability, productivity, and readability of reusable libraries. Overloading on the number of parameters makes it possible to provide simpler versions of constructors and methods. Overloading on the parameter type makes it possible to use the same member name for members performing identical operations on a selected set of different types.
Q73. DRAG DROP - (Topic 1)
You are developing an application by using C#. The application will output the text string "First Line" followed by the text string "Second Line".
You need to ensure that an empty line separates the text strings.
Which four code segments should you use in sequence? (To answer, move the appropriate code segments to the answer area and arrange them in the correct order.)
Answer:
Q74. - (Topic 2)
You are implementing a new method named ProcessData. The ProcessData() method calls a third-party component that performs a long-running operation to retrieve stock information from a web service.
The third-party component uses the IAsyncResult pattern to signal completion of the long-running operation so that the UI can be updated with the new values.
You need to ensure that the calling code handles the long-running operation as a System.Threading.Tasks.Task object to avoid blocking the UI thread.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
A. Create a TaskCompletionSource<T> object.
B. Call the component by using the TaskFactory.FromAsync() method.
C. Apply the following attribute to the ProcessData() method signature: [Methodlmpl(MethodlmplOptions.Synchronized)]
D. Apply the async modifier to the ProcessData() method signature.
Answer: A,B
Explanation: A: In many scenarios, it is useful to enable a Task<TResult> to represent an external asynchronous operation. TaskCompletionSource<TResult> is provided for this purpose. It enables the creation of a task that can be handed out to consumers, and those consumers can use the members of the task as they would any other. However, unlike most tasks, the state of a task created by a TaskCompletionSource is controlled explicitly by the methods on TaskCompletionSource. This enables the completion of the external asynchronous operation to be propagated to the underlying Task. The separation also ensures that consumers are not able to transition the state without access to the corresponding TaskCompletionSource.
B: TaskFactory.FromAsync Method
Creates a Task that represents a pair of begin and end methods that conform to the
Asynchronous Programming Model pattern. Overloaded.
Example:
TaskFactory.FromAsync Method (IAsyncResult, Action<IAsyncResult>)
Creates a Task that executes an end method action when a specified IAsyncResult completes.
Note:
* System.Threading.Tasks.Task Represents an asynchronous operation.
Q75. - (Topic 1)
You are developing an application. The application calls a method that returns an array of integers named customerIds. You define an integer variable named customerIdToRemove and assign a value to it. You declare an array named filteredCustomerIds.
You have the following requirements.
Remove duplicate integers from the customerIds array.
Sort the array in order from the highest value to the lowest value.
Remove the integer value stored in the customerIdToRemove variable from the
customerIds 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

Q76. DRAG DROP - (Topic 1)
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:
Q77. - (Topic 2)
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?
A. Configure the assembly metadata to use the pre-existing public key for the assembly identity by using the AssemblySignatureKeyAttribute attribute.
B. Disable the strong-name bypass feature of Microsoft .NET Framework in the registry.
C. Configure the Define DEBUG constant setting in Microsoft Visual Studio.
D. Decorate the code by using the [assembly:AssemblyDelaySignAttribute(true)] attribute.
Answer: C
Explanation: Use one debug version to connect to the development database, and a standard version to connect to the live database.
Q78. - (Topic 2)
You are developing an application that will be deployed to multiple computers. You set the assembly name.
You need to create a unique identity for the application assembly.
Which two assembly identity attributes should you include in the source code? (Each correct answer presents part of the solution. Choose two.)
A. AssemblyTitleAttribute
B. AssemblyCultureAttribute
C. AssemblyVersionAttribute
D. AssemblyKeyNameAttribute
E. AssemblyFileVersion
....
Answer: B,C
Explanation: The AssemblyName object contains information about an assembly, which you can use to bind to that assembly. An assembly's identity consists of the following:
Simple name
Version number
Cryptographic key pair
Supported culture
B: AssemblyCultureAttribute
Specifies which culture the assembly supports.
The attribute is used by compilers to distinguish between a main assembly and a satellite
assembly. A main assembly contains code and the neutral culture's resources. A satellite
assembly contains only resources for a particular culture, as in
[assembly:AssemblyCultureAttribute("de")]
C: AssemblyVersionAttribute
Specifies the version of the assembly being attributed.
The assembly version number is part of an assembly's identity and plays a key part in
binding to the assembly and in version policy.
Q79. - (Topic 1)
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
Explanation:
PerformanceCounterType.SampleBase - A base counter that stores the number of sampling interrupts taken and is used as a denominator in the sampling fraction. The sampling fraction is the number of samples that were 1 (or true) for a sample interrupt. Check that this value is greater than zero before using it as the denominator in a calculation of SampleFraction.
PerformanceCounterType.SampleFraction - A percentage counter that shows the average ratio of hits to all operations during the last two sample intervals. Formula: ((N 1 - N 0) / (D 1 - D 0)) x 100, where the numerator represents the number of successful operations during the last sample interval, and the denominator represents the change in the number of all operations (of the type measured) completed during the sample interval, using counters of type SampleBase. Counters of this type include Cache\Pin Read Hits %. http://msdn.microsoft.com/en-us/library/system.diagnostics.performancecountertype.aspx
