1. The ASP.NET Core Module is a native IIS module that plugs into the IIS pipeline to either _______.
- create IIS code the server needs in a file with the extension required, or run the IIS server in a mode compatible for ASP.NET Core
- host an ASP.NET Core app inside of the IIS worker process, called the out-of-process hosting model, or forward web requests to a backend
ASP.NET Core app running the Kestrel server, called the in-process hosting model - host an ASP.NET Core app inside of the IIS worker process, called the in-process hosting model, or forward web requests to a backend ASP.NET
Core app running the Kestrel server, called the out-of-process hosting model - package up your C# application and C# packages into .NET modules, or specify which of its packages should be visible to other .NET modules
2. You want to encapsulate a command request as an object. Which design pattern best fits this objective?
- Command
- Observer
- Iterator
- Facade
3. In the code below, what is the difference between RenderPartial and RenderAction?
@{
Html. RenderAction("Add");
Html. RenderPartial ("Add");
}
- RenderPartial will call an action method of the current controller and render a result inline. RenderAction will render the specified view inline
without calling any action method. - RenderPartial will call an action method of the current model and render a result inline. RenderAction will render the specified view inline without
calling any action method. - RenderAction will call an action method of the current model and render a result inline. RenderPartial will render the specified view inline without
calling any action method. - RenderAction will call an action method of the current controller and render a result inline. RenderPartial will render the specified view inline
without calling any action method.
4. What is the difference between a heap and a stack?
- The heap is stored value types; the stack is stored reference types.
- The stack contains stored value types; the heap contains stored reference types.
- The stack is stored object types; the heap is stored class types.
- The heap is stored object types; the stack is stored class types.
5. What is the Liskov substitution principle?
- Aclass should have only a single responsibility—that is, only changes to one part of the software’s specification should be able to affect the specification of the class.
- Many client-specific interfaces are better than one general-purpose interface.
- Obiects in a program should be replaceable with instances of their subtypes without altering the correctness of that program.
- Software entities should be open for extension, but closed for modification.
6. What is an interface in .NET?
- An interface is responsible for keeping track of what is actually executing and where each executing thread is.
- An interface declares a contract or behavior that implementing classes require. It may declare only properties, methods, and events with no
access modifiers. All the declared members must be implemented. - An interface allows developers to create new classes that reuse, extend, and modify the behavior defined in other classes
- An interface provides a partial implementation for functionality and some abstract or virtual members that must be implemented by the
inheriting entities. It can declare fields too.
7. How can you receive form data without a model binder in a controller action?
- public IFormResult ReceivedDataByRequest()
{string theName= Request.Forms/”theName” I:
return View() ;} - public IFormResult ReceivedDataByRequest()
{string theName= Request.Form| “theName”];
return View);} - public IActionResult ReceivedDataByRequest()
{string theName= Request.Form[“theName”] ;
return View() ;} - publie IActionResult ReceivedDataByRequest()
{string theName= Request.Forms[“theName”] ;
return view:}
8. You want to create an instance of several families of classes. Which design pattern best fits this objective?
- Abstract Factory
- Decorator
- Bridge
- Singleton
9. You want to create a class of which only a single instance can exist. Which design pattern best fits this objective?
- Decorator
- Singleton
- Bridge
- Adapter
10. What does CIL stand for?
- Commonly Interpreted Language
- Common Intermediate Language
- C# Intermediate Language
- C# Interpreted Language
11. What is the dependency inversion principle?
- Software entities should be open for extension, but closed for modification.
- A class should have only a single responsibility-that is, only changes to one part of the software’s specification should be able to affect the
specification of the class. - Objects in a program should be replaceable with instances of their subtypes without altering the correctness of that program
- Entities must depend on abstractions, not on concrete implementations
12. What is a thread?
- a series of related tasks or methods that together turn inputs into outputs
- a program that is running on your computer
- the basic unit to which an operating system allocates processor time
- a single operation that does not return a value and that usually executes asynchronously
13. What is a tuple?
- a group of classes designed specifically for grouping together objects and performing tasks on them
- a data structure that has a specific number and sequence of elements
- an object to store multiple variables of the same type in an array data structure
- an array whose elements are jagged
14. Which statement about a read-only variable is not true?
- It can be initialized at declaration onlv.
- At run time, its value is evaluated
- It can be initialized in either the constructor or the declaration
- It can be either static or an instance member.
15. What is a namespace?
- a group of generic collections-in a logical hierarchy by function–that enable you to access the core functionality you need in your applications
- a group of classes, structures, interfaces, enumerations, and delegates-organized in a logical hierarchy by function- that enable you to access
the core functionality you need in your applications - a group of methods-in a logical hierarchy by class–that enable you to access the core functionality you need in .NET
- a group of assemblies-in a logical hierarchy by function-that enable you to access the core functionality you need in your applications
