)
Q32. - (Topic 1)
You are developing an application that includes a class named Order. The application will store a collection of Order objects.
The collection must meet the following requirements:
Internally store a key and a value for each collection item. Provide objects to iterators in ascending order based on the key. Ensure that item are accessible by zero-based index or by key.
You need to use a collection type that meets the requirements.
Which collection type should you use?
A. LinkedList
B. Queue
C. Array
D. HashTable
E. SortedList
Answer: E
Explanation:
SortedList<TKey, TValue> - Represents a collection of key/value pairs that are sorted by key based on the associated IComparer<T> implementation. http://msdn.microsoft.com/en-us/library/ms132319.aspx
Q33. - (Topic 1)
You are developing an application that includes a class named Order. The application will store a collection of Order objects.
The collection must meet the following requirements:
Use strongly typed members.
Process Order objects in first-in-first-out order.
Store values for each Order object.
. Use zero-based indices.
You need to use a collection type that meets the requirements.
Which collection type should you use?
A. Queue<T>
B. SortedList
C. LinkedList<T>
D. HashTable
E. Array<T>
Answer: A
Explanation:
Queues are useful for storing messages in the order they were received for sequential processing. Objects stored in a Queue<T> are inserted at one end and removed from the other. http://msdn.microsoft.com/en-us/library/7977ey2c.aspx
Q34. - (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.
Q35. - (Topic 1)
You are developing an application that includes the following code segment. (Line numbers are included for reference only.)
The GetCustomers() method must meet the following requirements:
Connect to a Microsoft SQL Server database.
Populate Customer objects with data from the database.
Return an IEnumerable<Customer> collection that contains the populated
Customer objects.
You need to meet the requirements.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
A. Insert the following code segment at line 17: while (sqlDataReader.GetValues())
B. Insert the following code segment at line 14: sqlConnection.Open();
C. Insert the following code segment at line 14: sqlConnection.BeginTransaction();
D. Insert the following code segment at line 17: while (sqlDataReader.Read())
E. Insert the following code segment at line 17: while (sqlDataReader.NextResult())
Answer: B,D
Explanation:
SqlConnection.Open - Opens a database connection with the property settings specified by the ConnectionString.
http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlconnection.open.aspx SqlDataReader.Read - Advances the SqlDataReader to the next record. http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqldatareader.read.aspx
Q36. DRAG DROP - (Topic 2)
You are developing a class named Temperature.
You need to ensure that collections of Temperature objects are sortable.
You have the following code:
Which code segments should you include in Target 1, Target 2 and Target 3 to complete the code? (To answer, drag the appropriate code segments to the correct targets 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:
Q37. - (Topic 2)
You are modifying an existing application.
The application includes a Loan class and a Customer class. The following code segment defines the classes.
You populate a collection named customer-Collection with Customer and Loan objects by using the following code segment:
You create a largeCustomerLoans collection to store the Loan objects by using the following code segment:
Collection<Loan> largeCustomerLoans = new Collection<Loan>();
All loans with an Amount value greater than or equal to 4000 must be tracked.
You need to populate the largeCustomerLoans collection with Loan objects.
Which code segment should you use?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: D
Explanation: Must add to the largeCustomerLoans collection, not the customerLoanCollection.
We iterate through each customer in customerCollection and check each loan belonging to this customer.
Q38. - (Topic 2)
You are developing an application that will process personnel records.

Which class should you use?
A. System.Security.Cryptography.DES
B. System.Security.Cryptography.Aes
C. System.Security.Cryptography.TripleDES
D. System.Security.Cryptography.RC2
Answer: B
Q39. - (Topic 1)
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 throw an InvalidCastException exception if the obj object is not of type IDataContainer when accessing the Data property.
You need to meet the requirements. Which code segment should you insert at line 07?
A. var dataContainer = (IDataContainer) obj;
B. var dataContainer = obj as IDataContainer;
C. var dataContainer = obj is IDataContainer;
D. dynamic dataContainer = obj;
Answer: A

Q40. - (Topic 2)
You are developing an application that produces an executable named MyApp.exe and an assembly named MyApp.dll.

B. Produce program database (PDB) information when you compile the code.
C. Compile MyApp.exe by using the /unsafe compiler option.
D. Initializes a new instance of the AssemblyDelaySignAttribute class in the MyApp.dll constructor.
Answer: B
