What is the primary purpose of software maintenance?
A Updating documentation
B Fixing bugs
C Writing new features
D Improving design
Software maintenance involves fixing defects, making minor improvements, and ensuring the system continues to operate correctly. It includes correcting bugs, updating components, and adapting the system to changes in its environment.
What does code refactoring aim to achieve?
A Increase complexity
B Add features
C Optimize speed
D Improve readability
Code refactoring focuses on improving the structure and readability of the code without changing its functionality. It reduces technical debt, making the codebase easier to maintain and extend by other developers.
What is a key benefit of cloud native development?
A Easier deployment
B Simplified architecture
C Reduced security
D Faster manual testing
Cloud native development uses cloud platforms to build and deploy applications. It allows for greater scalability, flexibility, and easier deployment, as applications are designed to take full advantage of cloud infrastructure and services.
What does “technical debt” refer to in software development?
A Unoptimized code
B Outdated hardware
C Unused features
D Excessive documentation
Technical debt refers to the cost of maintaining suboptimal code or shortcuts taken during development. While these shortcuts may speed up initial development, they can lead to maintenance challenges and require refactoring in the future.
Which of the following is a common challenge in software maintenance?
A Writing documentation
B Reducing hardware costs
C Maintaining code quality
D Adding new features
Maintaining code quality during software maintenance is challenging due to the continuous changes and updates. Over time, the codebase may become harder to manage, requiring careful refactoring to avoid technical debt.
What is the goal of cloud native applications?
A Speed
B Scalability
C Redundancy
D Simplicity
Cloud native applications are designed to take advantage of cloud environments, offering scalability, resilience, and flexibility. They can automatically scale up or down based on demand, providing efficient resource usage and high availability.
What does “continuous integration” (CI) focus on in software development?
A Merging code changes
B Writing new features
C Automating deployment
D Generating reports
Continuous Integration (CI) focuses on merging code changes frequently into a shared repository. It automates the process of building, testing, and validating changes, which helps detect bugs early and ensures the code remains functional.
Which of the following is a part of software maintenance?
A Debugging existing code
B Managing version control
C Writing user documentation
D Designing new modules
Software maintenance includes activities like debugging, improving code, and adapting the software to changes in the environment or requirements. It ensures that the software continues to function correctly and meets evolving needs.
What is the primary advantage of microservices architecture in cloud native development?
A Centralized database
B Complexity management
C Scalability and flexibility
D Redundancy
Microservices architecture allows applications to be divided into small, independently deployable services. This approach enables greater scalability and flexibility, as each service can be scaled or updated without affecting the entire system.
What does code refactoring improve in software systems?
A Feature development
B Code maintainability
C Code duplication
D System architecture
Code refactoring improves the internal structure of code without altering its external behavior. It makes the code easier to maintain, understand, and extend, which helps prevent the system from becoming too rigid or difficult to modify.
What is a key benefit of using cloud native platforms for development?
A Improved scalability
B Lower development costs
C Simplified debugging
D Reduced code complexity
Cloud native platforms allow applications to scale easily based on demand. Resources can be dynamically allocated, making it possible to handle large scale traffic and ensure that the application remains performant even during peak usage periods.
What is the main goal of cloud native development in terms of infrastructure?
A Simpler architecture
B Centralized control
C Reduced deployment time
D Flexible and scalable resources
Cloud native development leverages cloud infrastructure to create flexible, scalable systems that can automatically adjust to changing demands. This flexibility ensures that the application can grow without significant manual intervention or overhauling the infrastructure.
What is typically the first step in the software maintenance process?
A Updating requirements
B Bug fixing
C Refactoring code
D Performance monitoring
The first step in software maintenance is often to update the software’s requirements based on user feedback or changes in the environment. This ensures that the software continues to meet its objectives after deployment.
Which of the following is essential in software maintenance?
A Adding new databases
B Enhancing system security
C Creating new features
D Ignoring legacy code
Enhancing security is a key part of software maintenance. As new vulnerabilities are discovered, maintaining a system’s security by applying patches and updates is critical to prevent potential threats and ensure continued safety.
What is the main focus of “cloud native” development?
A User interface design
B Cloud infrastructure use
C Reduced deployment time
D Simplified architecture
Cloud native development focuses on building applications that fully leverage cloud infrastructure. It involves using cloud services to enable faster scaling, high availability, and more resilient applications that are well suited for dynamic cloud environments.
