QUESTION 1
You work as the application developer at Certkiller .com. Certkiller .com uses Visual
Studio.NET 2005 as its application development platform. You use a Windwos XP
Professional client computer named Certkiller -WS554 as your development
computer.
You are developing a .NET Framework 2.0 application on Certkiller -WS554. You
are trying to port an old Certkiller .com management application that was written in
unmanaged Windows code with no COM interfaces. The application you are
developing makes calls to the old Certkiller .com management unmanaged library
namedBillPerformance.dll.
You are required to make a call to the GetPerformaceScore method of the
unmanaged Performance.dll library.
What should you do?
A. The Type Library Exporter tool (tlbexp.exe) should be used.
B. The Type Library Importer tool (tlbimp.exe) should be used.
C. The Assembly Registration tool (regasm.exe) should be used.
D. The Platform Invoke (DllImportAttribute) should be used.
Answer: D
Explanation: The feature Platform Invoke is used to allow you to call methods that
are in unmanaged libraries but you need to declare the unmanaged method in the
managed code using the extern and static keywords with the DllImport attribute
which is used to specify the unmanaged library.
Incorrect Answers:
A, B, C: The tool should not be considered for usage in the scenario because the
unmanaged dll file is not in COM and it only processes COM type libraries.
QUESTION 2
You work as the application developer at Certkiller .com. Certkiller .com uses Visual
Studio.NET 2005 as its application development platform. You use a Windwos XP
Professional client computer named Certkiller -WS536 as your development
computer.
You are developing a .NET Framework 2.0 Windows application on
Certkiller -WS536. Your application needs to call the GetComputerName method
in the library named kernel32.dll to display the computer name. You write the code
below:
Public Shared Function GetComputerNamer( _
ByVal IpBuffer As StringBuilder, ByRef IpnSize As Integer) As Boolean
End Function
You are required to call the method as ComputerName based on your coding
standards whilst you ensure that your code can be cancelled on any Windows
operating system. You need to know how to modify the DllImport attribute to call
the GetComputerName method.
What should you do?

A. The Entrypoint property must be set to “ComputerName”.
B. The CharSet property must be set to CharSet.Unicode.
C. The CharSet property must be set to CharSet.Ansi.
D. The EntryPoint property must be set to “GetComputerName”.
E. The CharSet property must be set to CharSet.Auto.
Answer: D, E
Explanation: The correct method to use in the scenario is to modify the DllImport
attribute and set the EntryPoint property to “GetComputerName” which is the
name of the method invoked in kernel32.dll but the .NET method should be
declared as ComputerName.
Incorrect Answers:
A, B, C: The methods used in the options could be used but require that the code be
changed significantly and you should not consider using the options in the scenario as
they are bound to fail.
QUESTION 3
You work as the application developer at Certkiller .com. Certkiller .com uses Visual
Studio.NET 2005 as its application development platform. You use a Windwos XP
Professional client computer named Certkiller -WS536 as your development
computer.
You are developing a .NET Framework 2.0 application on Certkiller -WS536. The
application will be used to list the available public types and methods in the
Certkiller .com assembly. You named the assembly strongly and it is installed in the
global assembly cache (GAL) and an assembly with the same identity is stored at
c:\ Certkiller \assemb\ Certkiller .com.dll.
You are required to dynamically load the Certkiller .com assembly into your
application whilst you ensure that the assembly is loaded from
c:\ Certkiller \assemb\ Certkiller .com.dll rather than the global assembly cache (GAL).
What code segment should you use?
A. Dim assemb As Assembly =
Assembly.LoadFrom(“c:\ Certkiller \assemb\ Certkiller .com.dll”)
B. Dim assemb As Assembly =
Assembly.LoadFile(“c:\ Certkiller \assemb\ Certkiller .com.dll”)
C. Dim assemb As Assembly = Assembly.ReflectionOnlyLoad(” Certkiller .com”)
D. Dim assemb As Assembly = Assembly.Load(” Certkiller .com”)
E. Dim assemb As Assembly = _
Assembly.ReflectionOnlyLoadFrom(“c:\ Certkiller \assemb\ Certkiller .com.dll”)
Answer: E
Explanation: To correctly load the Assembly class from the location
c:\ Certkiller \assemb\ Certkiller .com.dll you should make used of the method used in

Actualtests.org – The Power of Knowing
the option of the scenario.
Incorrect Answers:
A, B, C, D: The other methods of the assembly class will request the common language
runtime (CLR) to resolve the location of the assembly based on its identity therefore
these options should not be used in the scenario even though you provide the full
absolute path as a parameter.
