Question: You are creating an application that performs time-consuming calculations. You create a method named Calc that performs the calculations. You need to provide two integer values to Calc. What should you do? (Each answer forms part of the complete solution. Choose all that apply.) - VB.NET
A
Call ThreadPool.GetAvailableThreads to retrieve a handle to the thread.

B
Create a custom class that contains two integer members and create an instance of that class containing the values that you need to pass to the method.

C
Create a custom class that contains two integer members and a delegate for the Calc method and create an instance of that class containing the values you need to pass to the method.

D
Call ThreadPool.QueueUserWorkItem and pass the Calc method and the instance of the custom class.

E
Call ThreadPool.QueueUserWorkItem and pass only the instance of the custom class.

Question: You will create an application that starts a new Thread object to run a method. You want the Thread to run as quickly as possible, even if that means it receives more processor time than the foreground thread. Which code sample does this correctly? - VB.NET
A
Dim DoWorkThread As New Thread(New ThreadStart(AddressOf DoWork))
DoWorkThread.ThreadState = ThreadState.Running
DoWorkThread.Start()

B
Dim DoWorkThread As New Thread(New ThreadStart(AddressOf DoWork))
DoWorkThread.Priority = ThreadPriority.Highest
DoWorkThread.Start()

C
Dim DoWorkThread As New Thread(New ThreadStart(AddressOf DoWork))
DoWorkThread.Priority = ThreadPriority.Lowest
DoWorkThread.Start()

D
Dim DoWorkThread As New Thread(New ThreadStart(AddressOf DoWork))
DoWorkThread.ThreadState = ThreadState.WaitSleepJoin
DoWorkThread.Start()

Question: You are creating a method that is part of a custom class. The method might be run simultaneously within multiple threads. You need to ensure that no thread writes to the file while any thread is reading from the file. You want to provide the highest level of efficiency when multiple threads are reading from the file simultaneously. Which code sample should you use? - VB.NET
A
SyncLock file
' Read file
End SyncLock

B
SyncLock
' Read file
End SyncLock

C
Dim rwl As New ReaderWriterLock()
rwl.AcquireReaderLock()
' Read file
rwl.ReleaseReaderLock()

D
Dim rwl As New ReaderWriterLock()
rwl.AcquireReaderLock(10000)
' Read file
rwl.ReleaseReaderLock()

A
orders += 1

B
SyncLock orders
orders += 1
End SyncLock

C
Interlocked.Increment(orders)

D
