Q52. - (Topic 1)
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
Answer: D
Explanation:
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 Additional info http://stackoverflow.com/questions/513412/how-does-regexoptions-compiled-work

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:
Q54. DRAG DROP - (Topic 1)
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.
How should you complete the relevant 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.)

Q56. - (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. WaitForFullGCApproach()
D. WaitForPendingFinalizers()
Answer: B
Q57. HOTSPOT - (Topic 1)
You are implementing a library method that accepts a character parameter and returns a string.
If the lookup succeeds, the method must return the corresponding string value. If the lookup fails, the method must return the value "invalid choice."
You need to implement the lookup algorithm.
How should you complete the relevant code? (To answer, select the correct keyword in each drop-down list in the answer area.)
Answer:
Q58. - (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.
Q59. - (Topic 1)
You are developing an application that includes the following code segment. (Line numbers are included for reference only.)
The GetAnimals() method must meet the following requirements:
Connect to a Microsoft SQL Server database.
Create Animal objects and populate them with data from the database.
Return a sequence of populated Animal objects.
You need to meet the requirements.

B. Insert the following code segment at line 13: sqlConnection.Open();
C. Insert the following code segment at line 13: sqlConnection.BeginTransaction();
D. Insert the following code segment at line 16: while(sqlDataReader.Read())
E. Insert the following code segment at line 16: while(sqlDataReader.GetValues())
Answer: B,D
Explanation:
