What are the potential risks of ignoring or poorly resolving merge conflicts in a project?
- All of the Above
- Code Quality Degradation
- Integration Issues
- Loss of Data
Ignoring or poorly resolving merge conflicts can lead to integration issues, where incompatible changes clash, causing errors in the project. This can result in a loss of data and a decline in overall code quality.
What does a 404 HTTP status code indicate in web development?
- Authentication Required

What is the role of Kubernetes in a microservices architecture?
- Handling frontend development
- Managing DNS configurations
- Orchestrating and managing containers
- Running SQL queries
Kubernetes plays a crucial role in a microservices architecture by orchestrating and managing containers. It automates the deployment, scaling, and operation of application containers, making it easier to manage complex, distributed systems.
The practice of automatically testing code changes before merging them into the main branch is known as Continuous _______.
- Delivery
- Deployment
- Integration
- Testing
The correct term is Continuous Integration (CI). This practice involves automatically testing code changes as they are integrated into the main codebase, ensuring that the new code does not break existing functionality.
Explain the difference between logging and monitoring in the context of software systems.
- Logging captures application events and messages for debugging and analysis. Monitoring involves observing and measuring system behavior and performance in real-time.
- Logging is the process of tracking events within an application, while monitoring involves assessing the overall system health and performance.
- Logging focuses on security-related events, while monitoring tracks resource utilization.
- Monitoring is only relevant for large-scale applications, whereas logging is essential for all applications.
Logging and monitoring serve distinct purposes. Logging captures events for analysis and debugging, while monitoring observes real-time system behavior and performance. The correct option defines the difference accurately.

What is denormalization in database design, and when might it be appropriate to use?
- Adding Redundancy
- Increasing Normalization
- Reducing Normalization
- Removing Data Duplication
Denormalization in database design involves introducing redundancy by adding redundant data. It may be appropriate when read performance is a priority, and the cost of increased storage and potential update anomalies can be justified.
