Preview Questions DevOps | Role Specific Skill

Question 1: 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 2: You are tasked with optimizing the performance and scalability of your configuration management system to handle a rapidly growing infrastructure. What strategies do you employ?

Which action should you take?

Choose only one option

Upgrade the configuration management server's hardware and software to accommodate increased load and improve processing capabilities.

Implement caching mechanisms and data compression techniques to reduce network traffic and improve response times.

Distribute configuration management workloads across multiple servers to achieve horizontal scalability.

Optimize configuration scripts and modules to minimize execution time and resource consumption.

Question 3: Your team is adopting infrastructure as code (IaC) principles. You're tasked with converting existing server configurations into code. What's your approach?

Which action should you take?

Choose only one option

Manually recreate the configurations in your chosen IaC tool, ensuring accuracy and completeness.

Use configuration management tools to extract the existing configurations and convert them into code.

Collaborate with experienced team members to develop a standardized IaC structure and best practices.

Research and evaluate different IaC tools to find the one that best suits your team's needs and workflow.

Question 4: You are tasked with scaling your containerized application to handle increased traffic during peak hours. How do you leverage container orchestration capabilities to achieve this?

Which action should you take?

Choose only one option

Manually scale up the number of replicas for your application's deployment in the Kubernetes cluster.

Configure Horizontal Pod Autoscaler (HPA) to automatically scale the number of replicas based on CPU or memory utilization.

Utilize a service mesh like Istio to implement traffic splitting and gradually roll out new versions of your application to handle increased load.

Implement a combination of manual scaling, HPA, and service mesh capabilities to achieve optimal scalability and flexibility.

Question 5: You're responsible for monitoring a critical production system with high availability requirements. What metrics would you focus on to ensure system health and performance?

Which action should you take?

Choose only one option

Application uptime and availability.

Response times and latency for key user interactions.

Error rates and exception counts.

All of the above.

Question 6: You are tasked with improving the security posture of your IaC infrastructure and preventing potential breaches or misconfigurations. What strategies do you implement to achieve this goal?

Which action should you take?

Choose only one option

Integrate security scanning and vulnerability assessment tools into your CI/CD pipeline to identify and address security issues early in the development process.

Utilize policy-as-code frameworks to enforce security best practices and compliance standards during infrastructure provisioning and configuration changes.

Implement secrets management solutions to securely store and manage sensitive configuration data, such as API keys, passwords, and certificates.

Regularly conduct security audits and penetration testing to identify and remediate vulnerabilities in your IaC infrastructure.
