These are just a small sample from our library of 10,000+ questions. The actual questions on this VB.NET Online Test will be non-googleable.

🧐 Question


AppDomain Resource Scoping
Configuration Management
Resource Scoping
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:
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
Consider the following .NET C# code snippet implementing IDisposable pattern:
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
In a .NET application, you are using .NET Remoting to communicate between different application domains. You have the following server-side code:
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.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment VB.NET Online Test in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.

Read more about the proctoring features.

How do I interpret test scores?

The primary thing to keep in mind is that an assessment is an elimination tool, not a selection tool. A skills assessment is optimized to help you eliminate candidates who are not technically qualified for the role, it is not optimized to help you find the best candidate for the role. So the ideal way to use an assessment is to decide a threshold score (typically 55%, we help you benchmark) and invite all candidates who score above the threshold for the next rounds of interview.

What experience level can I use this test for?

Each Adaface assessment is customized to your job description/ ideal candidate persona (our subject matter experts will pick the right questions for your assessment from our library of 10000+ questions). This assessment can be customized for any experience level.

Does every candidate get the same questions?

Yes, it makes it much easier for you to compare candidates. Options for MCQ questions and the order of questions are randomized. We have anti-cheating/ proctoring features in place. In our enterprise plan, we also have the option to create multiple versions of the same assessment with questions of similar difficulty levels.

I'm a candidate. Can I try a practice test?

No. Unfortunately, we do not support practice tests at the moment. However, you can use our sample questions for practice.

What is the cost of using this test?

You can check out our pricing plans.
