What is the primary focus of the MVC architecture pattern?
A User interaction
B Code testing
C Data storage
D Separating concerns
The Model View Controller (MVC) architecture separates an application into three components: Model (data), View (user interface), and Controller (logic). This separation helps organize code, making it easier to maintain, test, and extend.
In the MVVM pattern, what role does the ViewModel play?
A Bind data to View
B Manage database
C Handle business logic
D Display data
In the MVVM (Model View ViewModel) pattern, the ViewModel binds data from the Model to the View. It acts as an intermediary, transforming data into a format suitable for display, allowing the View to focus only on rendering.
Which of the following best describes “Clean Architecture”?
A Single point control
B Layered and independent components
C Focusing on UI design
D Fast deployment process
Clean Architecture advocates for organizing software into layers with independent, reusable components. It promotes separation of concerns, making it easier to test, maintain, and scale, while ensuring flexibility and adaptability to changes.
What is the main purpose of security in software development?
A Managing UI components
B Writing more code
C Ensuring data protection
D Improving performance
Security in software development focuses on protecting data from unauthorized access, preventing breaches, and ensuring that systems remain secure. This involves techniques like encryption, authentication, and authorization to safeguard sensitive information.
What is the key feature of Full Stack Development?
A Involvement in both front end and back end
B Back end management
C Single technology use
D Focus on front end only
Full Stack Development involves both the front end (UI) and back end (server, database) aspects of web development. A full stack developer is proficient in multiple technologies, enabling them to build complete web applications.
In MVC, what does the “Model” represent?
A Business rules
B Data and logic
C Code structure
D UI design
In the MVC pattern, the “Model” represents the data and the business logic of the application. It handles data retrieval, processing, and storage, ensuring that the application’s functionality aligns with the user’s needs.
What is the role of the “Controller” in the MVC architecture?
A Display content
B Define database structure
C Manage data
D Handle user input
The Controller in MVC manages user input, processes it (often interacting with the Model), and updates the View accordingly. It acts as an intermediary between the user interface and the underlying logic or data.
In software architecture, what does “separation of concerns” aim to achieve?
A Clear division of responsibilities
B Simplified UI
C Faster development
D Single point configuration
Separation of concerns ensures that different aspects of a software application (e.g., data, UI, logic) are handled independently. This improves maintainability, scalability, and reduces complexity by allowing each part of the system to focus on a specific task.
Which security measure is essential to protect sensitive data in a system?
A Logging
B Authentication
C Caching
D Compression
Authentication ensures that only authorized users can access the system. It involves verifying user identities through methods like passwords, biometrics, or multi factor authentication, thus protecting sensitive data from unauthorized access.
What is the advantage of using MVC in software development?
A Enhances team collaboration
B Decreases user interaction
C Simplifies database design
D Reduces code complexity
MVC simplifies the development process by separating the application into three layers: Model, View, and Controller. This separation reduces code complexity, making it easier to manage and test individual components independently.
What is a major drawback of using monolithic software architecture?
A Limited scalability
B Centralized management
C Easier to maintain
D Faster development
Monolithic software architecture often faces limitations in scalability because all components are tightly coupled. As the system grows, scaling requires scaling the entire application, which can lead to performance bottlenecks and complex management.
Which of the following is NOT typically part of software security practices?
A Data masking
B Code encryption
C Code comments
D Penetration testing
Code comments are helpful for developers but are not part of security practices. Security practices focus on protecting data, preventing unauthorized access, and ensuring that vulnerabilities are addressed through techniques like encryption and penetration testing.
What is the main benefit of using Cloud Native development?
A Better cloud scalability
B Simpler code
C Static resource usage
D Faster debugging
Cloud Native development leverages cloud infrastructure to enable applications to scale easily. It allows for dynamic allocation of resources based on demand, improving performance and reliability while reducing the overhead associated with scaling traditional systems.
In Clean Architecture, which layer should depend on the outer layers?
A Only the database layer
B Inner layers
C All layers equally
D Outer layers
Clean Architecture follows the rule that inner layers (e.g., business logic) should not depend on outer layers (e.g., UI, databases). This ensures that core logic remains decoupled from external changes, improving flexibility and testability.
What does a “microservices architecture” primarily focus on?
A Centralized processing
B Single database use
C Scalability and flexibility
D Simple structure
Microservices architecture focuses on breaking down an application into small, independent services that can be developed, deployed, and scaled separately. This approach allows for greater scalability and flexibility, as each service can be independently managed and optimized.
