Preview Questions DevOps | Role Specific Skill

Question 1: Your organization is experiencing significant cost overruns in its cloud infrastructure spending. You are tasked with identifying and implementing cost optimization strategies while maintaining performance and reliability. What approach do you take?

Which action should you take?

Choose only one option

Conduct a thorough cost analysis, leveraging cloud provider billing data and resource utilization metrics, to identify areas of inefficiency and potential cost savings.

Implement cost optimization techniques, such as rightsizing instances, utilizing spot instances, and scheduling resource scaling based on demand patterns.

Review and refactor IaC templates and automation scripts to optimize resource provisioning and eliminate any unnecessary or underutilized resources.

Negotiate with cloud providers for better pricing and discounts, exploring options like reserved instances or committed use discounts for predictable workloads.

Question 2: You are leading a team that is adopting a shift-left security approach, integrating security practices earlier in the development lifecycle. How do you empower developers to take ownership of security and proactively address potential risks during the development process?

Which action should you take?

Choose only one option

Provide developers with training and resources on secure coding practices, threat modeling, and vulnerability management.

Integrate security testing tools and frameworks into the development environment, enabling developers to identify and fix security issues as they code.

Foster a culture of collaboration and open communication between development, operations, and security teams, encouraging them to work together to address security concerns.

Implement automated security checks and feedback loops within the CI/CD pipeline, providing developers with real-time insights into the security posture of their code.

Question 3: A critical vulnerability is discovered in a core component of your production infrastructure. The vendor has not yet released a patch, but there's a potential workaround available. What is your course of action?

Which action should you take?

Choose only one option

Immediately implement the workaround in production, accepting the potential risks and closely monitoring for any side effects.

Isolate the vulnerable component as much as possible, implementing compensating controls like network segmentation and additional monitoring.

Reach out to the vendor to inquire about the patch release timeline and explore potential mitigation strategies.

Halt all deployments and new feature development until a patch is available, prioritizing stability over agility.

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: You've deployed an application to AWS using EC2 instances. You're now seeing intermittent spikes in traffic that cause performance issues. What service could you use to automatically scale your application based on demand?

Which action should you take?

Choose only one option

AWS Elastic Beanstalk

AWS Auto Scaling

AWS Lambda

AWS Elastic Load Balancing

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.
