What is the main difference between Docker and Kubernetes?
- Container Orchestration
- Containerization
- Microservices
- Virtualization
The main difference between Docker and Kubernetes lies in their primary roles. Docker is primarily a containerization platform, allowing you to package and distribute applications. Kubernetes, on the other hand, is a container orchestration platform, managing the deployment, scaling, and operation of application containers.
What is the purpose of error handling in software development?
- Design user interfaces
- Identify and manage unexpected issues during program execution
- Implement new features
- Optimize code for better performance
Error handling in software development is crucial to identify and manage unexpected issues during program execution. It ensures graceful handling of errors, preventing application crashes and providing a better user experience.
What is a conflict resolution strategy in Git?
- Git Pull
- Manual Resolution
- Merge and Commit
- Revert to Previous Commit
Conflict resolution in Git often involves manually resolving conflicts that arise when merging branches. Developers must review the conflicting changes and decide how to combine them, ensuring the integrity of the codebase. This manual resolution is a crucial step to prevent introducing errors during the merge.
How can you handle typography in responsive design effectively?
- Embedding fonts directly into the HTML document, using only pixel units for font sizes
- Using only fixed font sizes, relying on default browser settings, ignoring line heights
- Using only percentage-based font sizes, ignoring the importance of line lengths in responsive typography
- Using relative units like em or rem, setting flexible font sizes with viewport units, and testing typography across different screen sizes
Effective handling of typography in responsive design involves using relative units such as em or rem, setting flexible font sizes with viewport units, and thorough testing across various screen sizes.
What is the significance of using branches in a version control system like Git during the pull request process?
- Enhances Code Collaboration
- Facilitates Parallel Development
- Improves Code Organization
- Reduces Code Conflicts
Branches in Git allow parallel development, enabling different features or fixes to be worked on simultaneously without interfering with each other. This promotes collaboration and keeps the main codebase clean.
You're working on a project with multiple team members. Two developers have made conflicting changes to the same function in different branches. How would you approach resolving this merge conflict?
- Automatically accept one developer's changes and discard the other, prioritizing speed over collaboration.
- Escalate the conflict to higher management for resolution.
- Merge both changes as-is, and let the codebase adapt to the differences.
- Review the changes, communicate with the developers, and collaboratively decide on the best resolution.
Resolving a merge conflict involves collaboration and communication. Reviewing changes together allows developers to discuss the best solution, fostering teamwork and understanding.
