Free CSA Application Design & Development Questions and Answers

Question 1

Which of the following best describes a key responsibility of a system architect?

Accepted Answer

Designing the overall system architecture

Answer

A system architect's key responsibility is designing the overall system architecture, which involves defining the high-level structure, components, and interactions of a software system. This role makes critical decisions about technology, infrastructure, and design patterns to ensure the system meets functional and non-functional requirements. Other options like testing code or installing hardware are typically handled by different technical roles.

Question 2

What is the purpose of application layering in system design?

Accepted Answer

To improve scalability and maintainability

Answer

Application layering separates different concerns of an application (e.g., presentation, business logic, data access) into distinct, manageable layers. This modularity significantly improves scalability by allowing individual layers to be scaled independently based on demand. It also enhances maintainability, as changes in one layer have minimal impact on others, simplifying development and updates.

Question 3

Which environment is typically used for deploying tested and validated applications?

Accepted Answer

Production

Answer

The production environment is the live system where end-users interact with the application. It is the final stage for deploying applications that have successfully passed through development, testing, and staging environments. This ensures that only stable, validated, and fully functional software is made available to the public.

Question 4

In application development, what does MVC stand for?

Accepted Answer

Model-View-Controller

Answer

MVC stands for Model-View-Controller, an architectural pattern widely used for developing user interfaces. It separates an application into three distinct components: the Model (data and business logic), the View (user interface), and the Controller (handles user input). This separation of concerns enhances modularity, making applications easier to develop, maintain, and test.

Question 5

What is a key benefit of modular design in system architecture?

Accepted Answer

Improved code reuse and testing

Answer

Modular design breaks down a system into smaller, independent, and interchangeable components. This approach significantly improves code reuse, as modules can be utilized across different parts of an application or even in other projects. It also simplifies testing, as individual modules can be tested in isolation, leading to more robust and reliable software.
