MCSD.NET - 70-330 Exam Interview Question:

Suppose You are an application developer for your company. You develop library assemblies that are
called by your main applications. These library assemblies access confidential data in the
applications. To ensure that this data is not accessed in an unauthorized and unsafe manner,
users must not be allowed to call the library assemblies from their own applications. You apply a
strong name to all assemblies to support versioning. You need to prevent users from writing
managed applications that make calls to your library assemblies. You need to achieve this goal
while minimizing the impact on response times for applications. What should you do?
A. Use the internal access modifier to declare all classes and structs in each library.
B. Use the protected internal access modifier to declare all classes and structs in each library.
C. Add the following attribute to each class and struct in each library assembly.
<StrongNameIdentityPermission(SecurityAction.Demand, PublicKey:="002400..bda4")>
D. Add the following attribute to each class and struct in each library assembly.
<StrongNameIdentityPermission(SecurityAction.LinkDemand, PublicKey:="002400..bda4")>
