Question 1: You are leading a team that is adopting a GitOps approach to configuration management. You encounter resistance from some team members who are accustomed to traditional configuration management practices. How do you overcome this resistance and ensure a successful transition?

Which action should you take?

Choose only one option

Conduct comprehensive training sessions and workshops to educate team members on the benefits and principles of GitOps, emphasizing its advantages in terms of collaboration, auditability, and reproducibility.

Organize hands-on exercises and simulations to provide practical experience with GitOps tools and workflows, allowing team members to gain confidence and familiarity with the new approach.

Foster open communication and address concerns raised by team members, highlighting the potential benefits of GitOps in terms of improved productivity, reduced errors, and increased agility.

Gradually introduce GitOps practices, starting with smaller, less critical components and expanding its adoption as the team gains experience and confidence.

Question 2: Your team is experiencing frequent pipeline failures due to inconsistent environment configurations between development, staging, and production. How do you address this?

Which action should you take?

Choose only one option

Implement configuration management tools to enforce consistency across all environments.

Standardize environment setup scripts and configurations to minimize variations.

Utilize containerization to package applications with their dependencies, ensuring consistent execution across environments.

Introduce automated environment provisioning and configuration tools to eliminate manual errors.

Question 3: A critical bug is discovered in production, but the tests didn't catch it. What's your next step?

Which action should you take?

Choose only one option

Add a new test case to the pipeline to prevent similar bugs in the future.

Review and enhance the existing test suite to improve its coverage.

Conduct a root cause analysis to understand why the bug wasn't detected.

Implement stricter code review processes to catch potential issues earlier.

Question 4: You notice a vulnerability in a third-party library used by your application. The library maintainers have released a patch. What's your next step?

Which action should you take?

Choose only one option

Immediately apply the patch to production systems to mitigate the risk.

Test the patch in a staging environment before applying it to production.

Inform the security team about the vulnerability and await further instructions.

Research workarounds or alternative libraries that don't have the vulnerability.

Question 5: Your team is adopting a new configuration management tool to replace an existing legacy system. How do you ensure a smooth transition and minimize disruption to ongoing operations?

Which action should you take?

Choose only one option

Conduct a thorough evaluation of the new tool's capabilities and compatibility with existing infrastructure and processes.

Develop a detailed migration plan, including data migration, configuration conversion, and testing procedures.

Provide comprehensive training and support to team members on the new tool and its workflows.

Gradually phase out the legacy system, starting with non-critical components and closely monitoring the impact.

Question 6: You are tasked with migrating a large, complex, and tightly coupled legacy application to a cloud-native microservices architecture using IaC. What is your primary focus during this transformation to minimize disruption and ensure a successful migration?

Which action should you take?

Choose only one option

Break down the monolithic application into smaller, loosely coupled microservices, each with its own IaC configuration, to enable independent development and deployment.

Implement a strangler fig pattern, gradually replacing legacy components with new microservices while maintaining compatibility and minimizing downtime.

Design a comprehensive testing and validation strategy to ensure functional and performance parity between the legacy and new architectures before cutover.

Establish a robust rollback plan to quickly revert to the previous state in case of unexpected issues during the migration process.
