AppDomain Resource Scoping
Configuration Management
AppDomain
Resource Scoping
Solve
Consider a scenario where you have a .NET application that needs to load different configurations for different components running in separate AppDomains. You have the following code structure:
 image
The `ConfigManager` class is designed to load and store configurations for different domains. What will be the output of this program, assuming `ConfigA.xml` and `ConfigB.xml` contain distinct settings?
A: Config in DomainA: [Settings from ConfigA.xml], Config in DomainB: [Settings from ConfigB.xml]
            B: Config in DomainA: null, Config in DomainB: null
            C: Config in DomainA: [Settings from ConfigB.xml], Config in DomainB: [Settings from ConfigA.xml]
            D: A runtime exception is thrown due to cross-domain operation.
            E: Config in DomainA: [Settings from ConfigA.xml], Config in DomainB: [Settings from ConfigA.xml]
            F: The output is unpredictable and depends on the runtime environment.

IDisposable Pattern
Garbage Collection
IDisposable Pattern
Memory Management
Solve
Consider the following .NET C# code snippet implementing IDisposable pattern:
 image
What is true about the garbage collection and resource management in this code?
A: The finalizer will always be called when the object is garbage collected.
            B: The `Dispose` method is only called when explicitly invoked.
            C: Managed resources will be freed in the finalizer.
            D: Unmanaged resources are only freed if `Dispose` is called with `true`.
            E: The `GC.SuppressFinalize` method prevents the finalizer from being called.
            F: The `using` statement ensures that unmanaged resources are always freed.

Remoting and Object Lifetime
.NET Remoting
Object Lifetime
MarshalByRefObject
Solve
In a .NET application, you are using .NET Remoting to communicate between different application domains. You have the following server-side code:
 image
This `RemoteObject` class is hosted in one application domain and accessed from another. Considering the lease settings (InitialLeaseTime, SponsorshipTimeout, RenewOnCallTime), what will happen if a client accesses the `GetData` method every 3 seconds?
A: The object will be disconnected after 5 seconds, regardless of the calls.
            B: The lease will be renewed, and the object remains accessible as long as it's called every 3 seconds.
            C: The object will be disconnected after 7 seconds, even with the regular calls.
            D: An exception will be thrown due to lease timeout.
            E: The lease will be renewed indefinitely without disconnection.
            F: The object will be disconnected only if there is a call after 5 seconds but within 7 seconds.
