Q1. - (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

Q2. - (Topic 1)

You are developing an application that will transmit large amounts of data between a client computer and a server. You need to ensure the validity of the data by using a cryptographic hashing algorithm. Which algorithm should you use?

A. DES

B. HMACSHA512

C. RNGCryptoServiceProvider

D. ECDsa

Answer: B

Q3. HOTSPOT - (Topic 1)

You are reviewing the following code:

For each of the following statements, select Yes if the statement is true. Otherwise, select No.

Answer:

Q4. - (Topic 2)

You are developing an application that uses a .config file.

The relevant portion of the .config file is shown as follows:

You need to ensure that diagnostic data for the application writes to the event log by using the configuration specified in the .config file.

What should you include in the application code?

A. Option A

B. Option B

C. Option C

D. Option D

Answer: A

Explanation: Explanation

http://msdn.microsoft.com/en-us/library/vstudio/system.diagnostics.eventlogtracelistener

Public static void Main(string[] args) {

Create a trace listener for the event log.

EventLogTraceListener myTraceListener = new

EventLogTraceListener("myEventLogSource");

Add the event log trace listener to the collection.

Trace.Listeners.Add(myTraceListener);

// Write output to the event log.

Trace.WriteLine("Test output");

}

Q5. - (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

Q6. - (Topic 1)

You are developing an application by using C#.

The application includes an object that performs a long running process.

You need to ensure that the garbage collector does not release the object's resources until the process completes.

Which garbage collector method should you use?

A. WaitForFullGCComplete()

B. SuppressFinalize()

C. collect()

D. RemoveMemoryPressure()

Answer: B

Q7. - (Topic 1)

You are developing an application by using C#. You provide a public key to the

development team during development.

You need to specify that the assembly is not fully signed when it is built.

Which two assembly attributes should you include in the source code? (Each correct

answer presents part of the solution. Choose two.)

A. AssemblyFlagsAttribute

B. AssemblyKeyFileAttribute

C. AssemblyConfigurationAttribute

D. AssemblyDelaySignAttribute

Answer: B,D

Q8. - (Topic 2)

You need to write a method that combines an unknown number of strings. The solution must minimize the amount of memory used by the method when the method executes.

What should you include in the code?

A. The String.Concat method

B. The StringBuilder.Append method

C. The + operator

D. The += operator

Answer: A

Explanation: A: String.Concat Method Concatenates one or more instances of String, or the String representations of the values of one or more instances of Object.

Q9. - (Topic 1)

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?

A. Option A

B. Option B

C. Option C

D. Option D

Answer: C

Explanation:

When you define a generic class, you can apply restrictions to the kinds of types that client code can use for type arguments when it instantiates your class. If client code tries to instantiate your class by using a type that is not allowed by a constraint, the result is a compile-time error. These restrictions are called constraints. Constraints are specified by using the where contextual keyword. http://msdn.microsoft.com/en-us/library/d5x73970.aspx

Q10. DRAG DROP - (Topic 2)

You are creating a class named Data that includes a dictionary object named _data.

You need to allow the garbage collection process to collect the references of the _data object.

You have the following code:

Which code segments should you include in Target 1 and Target 2 to complete the 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.)
