Which of the following best describes the Presentation Layer in a typical 3-layer architecture?. The layer that processes business logic and makes calculations. The layer that acts as an interface between users and the system. The layer that stores data permanently.

The Presentation Layer can exist in both frontend (like web or mobile UI) and backend (like API endpoints) contexts. True. False.

In the context of backend development, which of the following components usually belong to the Presentation Layer?. Controllers and routes. Database models. Business services.

Which statement correctly describes the responsibility of the Presentation Layer?. It coordinates database connections and ensures data consistency. It provides a bridge between user actions and backend processes. It defines how business logic is executed in the system.

Which of the following best represents the typical structure of the Presentation Layer?. Controllers, Views, Templates, and Routes. Entities, Repositories, and Data Access Objects. Services, Business Logic, and Database Connections.

Controllers in the Presentation Layer are responsible for implementing business logic. True. False.

In an MVC (Model–View–Controller) architecture, which component of the Presentation Layer defines how the data is displayed to users?. View. Model. Controller.

Which of the following best describes the role of templates in the Presentation Layer?. They define reusable structures for displaying dynamic content. They store data retrieved from the database. They handle routing logic and input validation.

APIs such as REST or GraphQL can also be part of the Presentation Layer. True. False.

What is the primary function of routing within the Presentation Layer?. To define how the application connects to the database. To map incoming requests (URLs/endpoints) to specific controllers or actions. To perform data validation and sanitization.

Which of the following statements best describes the implementation of the Presentation Layer in backend frameworks?. It’s implemented using controllers, routes, and view engines or APIs. It’s implemented using database connectors and query builders. It’s implemented using background services and schedulers.

In Express.js, the Presentation Layer is implemented using middleware only. True. False.

In Spring Boot, which component is primarily responsible for the Presentation Layer?. @RestController or @Controller classes. @Service classes. @Repository interfaces.

In Django, how is the Presentation Layer commonly implemented?. Through models and migrations. Through views, templates, and URL configurations. Through serializers and managers.

True or False: When implementing the Presentation Layer, one key goal is to keep it independent from business and data logic. True. False.

When building an API-based Presentation Layer, which of the following steps is part of the implementation?. Designing endpoints and defining response formats (JSON, XML, etc.). Managing database indexes and queries. Configuring server hardware and networking.
