Exploring DevOps Fundamentals

What are the core principles of DevOps?

• Isolation, Manual Processes, Waterfall Development

• Limited Communication, Static Testing, Documentation Focus

• Single Responsibility, No Feedback Loops, Risk Aversion

• Collaboration, Automation, CI/CD, Monitoring, Culture of Experimentation.

How does Continuous Integration improve software quality?

• Continuous Integration improves software quality by facilitating early bug detection, ensuring code stability through automated testing, and enhancing team collaboration.

• Continuous Integration is only beneficial for large teams.

• Continuous Integration eliminates the need for testing.

• Continuous Integration slows down the development process.

What is Infrastructure as Code and why is it important?

• Infrastructure as Code is a method of managing infrastructure through code, which is important for automation, consistency, and version control.

• Infrastructure as Code is only useful for small projects.

• Infrastructure as Code eliminates the need for any documentation.

• Infrastructure as Code is a physical server management technique.

What tools are commonly used for monitoring applications?

• Prometheus, Grafana, New Relic, Datadog, Splunk, AppDynamics

• Jira

• Slack

• Trello

How does logging contribute to effective DevOps practices?

• Logging has no impact on team communication.

• Logging enhances visibility, troubleshooting, and collaboration in DevOps practices.

• Logging slows down deployment processes.

• Logging is only useful for security audits.

What role do collaboration tools play in DevOps?

• Collaboration tools hinder communication in DevOps.

• Collaboration tools are primarily for documentation purposes.

• Collaboration tools enhance communication, streamline workflows, and promote teamwork in DevOps.

• Collaboration tools are only used for project management.

Can you explain the Agile methodology in the context of DevOps?

• Agile methodology discourages team collaboration and communication.

• Agile methodology is solely focused on documentation and reporting.

• Agile methodology emphasizes strict adherence to a predefined plan.

• Agile methodology in DevOps focuses on iterative development, collaboration, and continuous delivery, enhancing software quality and speed.

What is the significance of automated testing in Continuous Integration?

• Automated testing is crucial in Continuous Integration as it enables early bug detection, enhances code quality, and speeds up the development process.

• Automated testing is not necessary in Continuous Integration.

• Automated testing is only useful for large teams.

• Automated testing slows down the development process.

How do version control systems support DevOps practices?

• They are used solely for project management tasks.

• Version control systems support collaboration, track changes, enable code reviews, and integrate with CI/CD pipelines.

• They prevent any collaboration between team members.

• They only store the final version of the code.

What are the benefits of using containers in DevOps?

• Increased complexity in deployment

• Benefits of using containers in DevOps include consistency across environments, isolation of applications and dependencies, improved resource efficiency, and enhanced CI/CD capabilities.

• Limited scalability of services

• Reduced security for applications
