Preview Questions DevOps | Role Specific Skill

Question 1: You are onboarding a new team member who is unfamiliar with your organization's CI/CD pipeline. How do you ensure their successful integration and contribution to the team?

Which action should you take?

Choose only one option

Provide comprehensive documentation and training materials on the pipeline's architecture and processes.

Assign them a mentor or buddy to guide them through the pipeline and answer their questions.

Encourage them to shadow experienced team members during pipeline execution and troubleshooting.

All of the above.

Question 2: You're using Prometheus to monitor your Kubernetes cluster. You want to create an alert when the number of pods in a deployment drops below a certain threshold. How would you do this?

Which action should you take?

Choose only one option

Write a PromQL query to track the number of pods and configure an alert rule in Alertmanager.

Use Kubernetes events to trigger alerts when pods are terminated or fail to start.

Set up a custom script to periodically check the number of pods and send alerts if necessary.

Rely on Kubernetes' built-in health checks to detect pod failures and trigger alerts.

Question 3: During a security audit, it is found that some sensitive data is stored in plain text in a configuration file. How do you rectify this?

Which action should you take?

Choose only one option

Encrypt the sensitive data and store the encryption key securely.

Restrict access to the configuration file to authorized personnel only.

Move the sensitive data to a more secure location, like a secrets management tool.

Obfuscate the sensitive data using a simple encoding scheme.

Question 4: You are leading a team that is adopting a serverless computing model for new application development. How do you ensure that your monitoring and observability strategies are adapted to effectively monitor and troubleshoot serverless functions and workflows?

Which action should you take?

Choose only one option

Rely on cloud provider-specific monitoring and logging tools to gather metrics and events related to your serverless functions, such as invocation counts, execution times, and error rates.

Instrument your serverless functions with custom metrics and distributed tracing capabilities to gain deeper insights into their behavior and performance.

Utilize third-party monitoring and observability platforms that offer specialized support for serverless architectures, providing features like function-level tracing and cold start analysis.

Implement a combination of cloud-native monitoring, custom instrumentation, and third-party tools to achieve comprehensive observability of your serverless environment.

Question 5: You are tasked with implementing a continuous deployment strategy for your organization. What key considerations do you take into account?

Which action should you take?

Choose only one option

Ensure comprehensive test coverage across all stages of the pipeline to minimize the risk of production failures.

Establish clear rollback procedures to quickly revert deployments in case of unexpected issues.

Implement monitoring and alerting mechanisms to track application performance and identify potential problems in real-time.

All of the above.

Question 6: You are leading a large-scale containerization initiative involving the migration of hundreds of legacy applications to a containerized environment. How do you ensure a smooth and efficient migration process while minimizing disruption to existing services?

Which action should you take?

Choose only one option

Conduct a thorough assessment of each application's dependencies, configurations, and potential compatibility issues with containerization technologies.

Develop a phased migration plan, prioritizing applications based on their criticality and complexity, and gradually transitioning them to containers.

Implement automated testing and validation procedures to ensure that containerized applications function correctly and meet performance requirements before deployment.

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