Layered Architecture

What is the main purpose of layered architecture in software design?

• To add complexity

• To enhance system speed

• To divide applications into distinct layers for modularity

• To reduce the number of functions in an application

Which of the following layers handles user interactions in layered architecture?

• Presentation Layer

• Application Layer

• Business Layer

• Data Layer

The Business Logic Layer (BLL) primarily deals with:

• User interface elements

• Core business rules and processes

• Database storage

• Data encryption

What makes layered architecture easier to update or modify?

• Each layer's independence and separation

• The addition of unnecessary layers

• Lower testability

• Increased data redundancy

What is a common challenge associated with dependencies in layered architecture?

• Reduced modularity

• Complex dependency management as the application grows

• Limited reusability

• Reduced testability
