QUESTION 1
You write the following method (line numbers are included for reference only):
You need to ensure that the method extracts a list of URLs that match the following pattern:
@http://(www\.)?([^\.]+)\.com;
Which code should you insert at line 07?
A. Option A
B. Option B
C. Option C
D. Option D
Correct Answer: C
Explanation: * MatchCollection
Represents the set of successful matches found by iteratively applying a regular expression pattern to the input string.
The collection is immutable (read-only) and has no public constructor. The Regex.Matches method returns a MatchCollection object.
* List.Add Method Adds an object to the end of the List. Incorrect: Not A: Gives groups array. Hence Tostring(0 method
mentioned above won\\’t give desird result Not D: ICollection.SyncRoot Property For collections whose underlying store
is not publicly available, the expected implementation is to return the current instance. Note that the pointer to the
current instance might not be sufficient for collections that wrap other collections; those should return the underlying
collection\\’s SyncRoot property.

QUESTION 2
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. ECDsa
B. RNGCryptoServiceProvider
C. Rfc2898DeriveBytes
D. HMACSHA512
Correct Answer: D
Explanation: The HMACSHA512 class computes a Hash-based Message Authentication Code (HMAC) using the
SHA512 hash function.
Reference: https://msdn.microsoft.com/enus/library/system.security.cryptography.hmacsha512(v=vs.110).aspx
QUESTION 3
You are developing code for an application that retrieves information about Microsoft .NET Framework assemblies.
The following code segment is part of the application (line numbers are included for reference only):
You need to insert code at line 04. The code must load the assembly. Once the assembly is loaded, the code must be
able to read the assembly metadata, but the code must be denied access from executing code from the assembly.
Which code segment should you insert at line 04?
A. Assembly.ReflectionOnlyLoadFrom(bytes);
B. Assembly.ReflectionOnlyLoad(bytes);
C. Assembly.Load(bytes);
D. Assembly.LoadFrom(bytes);
Correct Answer: B
Explanation: The Assembly.ReflectionOnlyLoad method (Byte[]) loads the assembly from a common object file format
(COFF)-based image containing an emitted assembly. The assembly is loaded into the reflection-only context of the
caller\\’s
application domain. You cannot execute code from an assembly loaded into the reflection-only context.
Incorrect:
Not A: The Assembly.ReflectionOnlyLoadFrom method (String) loads an assembly into the reflection-only context, given
its path.
Reference: Assembly.ReflectionOnlyLoad Method (Byte[]) https://msdn.microsoft.com/enus/library/h55she1h(v=vs.110).aspx
QUESTION 4
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
Correct Answer: D
RegexOptions.Compiled – Specifies that the regular expression is compiled to an assembly.This yields faster execution
but increases startup time.This value should not be assigned to the Options property when calling the
CompileToAssembly method. http://msdn.microsoft.com/en-us/library/system.text.regularexpressions.regexoptions.aspx

QUESTION 5
You are developing an application that uses multiple asynchronous tasks to optimize performance.
You need to retrieve the result of an asynchronous task.
Which code segment should you use?
A. Option A
B. Option B
C. Option C
D. Option D
Correct Answer: C
Explanation: Use the async modifier to specify that a method, lambda expression, or anonymous method is asynchronous. If you use this modifier on a method or expression, it\\’s referred to as an async method.
Example:
public async Task ExampleMethodAsync()
{
// . . . .
}
Reference: async (C# Reference)

QUESTION 6
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;
Correct Answer: A
direct cast. If object is not of the given type, an InvalidCastException is thrown.
Incorrect:
Not B: If obj is not of the given type, result is null. Not C: If obj is not of a given type, result is false. Not D: This simply
check the variable during runtime. It will not throw an exception.
Reference: http://msdn.microsoft.com/en-us/library/ms173105.aspx
QUESTION 7
You are creating an application that processes a list of numbers.
The application must define a method that queries the list and displays a subset of the numbers to the user. The method
must not update the list.
You need to create an extendable query by using LINQ.
What should you do?
A. Option A
B. Option B
C. Option C
D. Option D

Which code should you insert at line 03?
A. Option A
B. Option B
C. Option C
D. Option D
Correct Answer: C
Explanation: ^\d+(.\d\d)?$ only allows positive numbers.
Incorrect:
^(-)?\d+(.\d\d)?$ allows for negative numbers because of the (-) group
QUESTION 10
You are developing an application.
The application contains the following code segment (line numbers are included for reference only):
When you run the code, you receive the following error message: “Cannot implicitly convert type \\’object\\’\\’ to \\’int\\’.
An explicit conversion exists (are you missing a cast?).”
You need to ensure that the code can be compiled.
Which code should you use to replace line 05?
A. var2 = arrayl[0] is int;
B. var2 = ((List)arrayl) [0];
C. var2 = arrayl[0].Equals(typeof(int));
D. var2 = (int) arrayl [0];
Correct Answer: D
QUESTION 11
DRAG DROP
You are creating a method that saves information to a database.
You have a static class named LogHelper. LogHelper has a method named Log to log the exception.
You need to use the LogHelper Log method to log the exception raised by the database server. The solution must
ensure that the exception can be caught by the calling method, while preserving the original stack trace.
How should you write the catch block? (Develop the solution by selecting and ordering the required code snippets. You
may not need all of the code snippets.)

QUESTION 12
HOTSPOT
You plan to implement the following interfaces:
You have the following methods:
getCelsiusFromKelvin returns the temperature in Celsius. getFahrenheitFromKelvin returns the temperature in
Fahrenheit.
You need to implement both interfaces within a class named TempControl. The TempControl class must return the
Celsius temperature as the default temperature if the following code executes.
How should you implement the interfaces? To answer, select the appropriate options in the answer area. NOTE: Each
correct selection is worth one point.
Hot Area:
Correct Answer:
QUESTION 13
You are adding a public method named UpdateGrade to a public class named ReportCard.
The code region that updates the grade field must meet the following requirements:
It must be accessed by only one thread at a time. It must not be vulnerable to a deadlock situation.
You need to implement the UpdateGrade() method.
What should you do?
A. Option A
B. Option B
C. Option C
D. Option D
Correct Answer: A
Explanation: Because the class is public, you need a private lock Object.
Incorrect:
Not B, not C: Once the ReportCard is public, other process can lock on type or instance.
So, these options are leaning to a DEADLOCK.
Not D: [MethodImpl] attribute works locking on type (for static members) or on the instance(for instance members). It could cause a DEADLOCK.
