Layered Architecture Quiz

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

In layered architecture, what is the primary role of the Data Layer?

• Manage user interface

• Handle business logic

• Provide data storage and management

• Perform encryption and decryption

What is a key benefit of separating concerns into different layers?

• Reduced performance overhead

• Simpler and more modular development

• Complexity in dependency management

• Reduced testability

Which layer is responsible for transforming structured data objects into physical SDOs?

• Presentation Layer

• Business Layer

• Persistence Layer

• Application Layer

What is the main advantage of modularity in layered architecture?

• Slower development

• Easier management and debugging

• Increased dependency issues

• Complex testing

Which element of layered architecture defines the rules for data exchange between layers?

• Service

• Protocol

• Interface

• Layer

A database abstraction layer (DBAL) enables:

• Direct user interface design

• Simplified communication with different databases

• Encryption of data for security

• Creation of business logic

Which feature of layered architecture allows testing each layer independently?

• Complexity

• Scalability

• Testability

• Security
