Preview Questions DevOps | Role Specific Skill

Question 1: You've just joined a team where the CI/CD pipeline is frequently failing due to flaky tests. How do you address this?

Which action should you take?

Choose only one option

Temporarily disable the flaky tests to unblock the pipeline and investigate later.

Prioritize identifying and fixing the root cause of the flaky tests.

Implement retries for the flaky tests to see if they pass on subsequent attempts.

Add more logging and monitoring to the pipeline to better understand the test failures.

Question 2: You receive an alert about suspicious activity on one of your production servers. What is your initial response?

Which action should you take?

Choose only one option

Immediately isolate the server from the network to prevent further compromise.

Review the logs and system activity to understand the nature of the suspicious activity.

Contact the security team to report the incident and request assistance.

Restart the server to clear any potential malicious processes.

Question 3: You need to securely store and manage sensitive configuration data, such as database credentials or API keys, for your containerized applications. What is the best practice for handling this information?

Which action should you take?

Choose only one option

Store sensitive data as environment variables within the container, ensuring they are not exposed in container logs or configuration files.

Utilize Kubernetes Secrets or similar mechanisms to store sensitive data securely and make them accessible to containers at runtime.

Encrypt sensitive data and store it in a separate configuration file mounted as a volume within the container.

Hardcode sensitive data directly into the application code, ensuring it's obfuscated or encrypted to prevent unauthorized access.

Question 4: Your team is adopting a new CI/CD tool. How do you ensure a smooth transition?

Which action should you take?

Choose only one option

Set up a parallel pipeline with the new tool and gradually migrate projects.

Conduct thorough training sessions for the team on the new tool.

Create detailed documentation and guides for using the new tool.

Assign a dedicated team member to champion the adoption of the new tool.

Question 5: You are responsible for managing secrets and sensitive configuration data within your configuration management system. How do you ensure the security and confidentiality of this information while maintaining ease of use and accessibility for authorized personnel?

Which action should you take?

Choose only one option

Encrypt sensitive data at rest and in transit using strong encryption algorithms and key management practices, ensuring that only authorized personnel have access to the decryption keys.

Utilize a secrets management solution to store and retrieve sensitive data securely, integrating it seamlessly with your configuration management tools and workflows.

Implement role-based access control and least privilege principles to restrict access to sensitive configuration data based on user roles and responsibilities.

Regularly audit and review access logs and configuration changes to detect any unauthorized access or suspicious activity related to sensitive data.

Question 6: You observe a growing trend of configuration drift across your infrastructure, leading to inconsistencies and potential issues. How do you address this challenge?

Which action should you take?

Choose only one option

Implement configuration management tools to enforce desired state configurations across all environments.

Utilize infrastructure as code (IaC) practices to codify and automate infrastructure provisioning and configuration.

Introduce regular audits and reconciliation processes to identify and rectify configuration drift.

Strengthen change management processes to track and control modifications to infrastructure configurations.
