Preview Questions DevOps | Role Specific Skill

Question 1: You are deploying a containerized application to a production environment, but you want to minimize downtime and ensure a smooth rollout. What deployment strategy do you choose to achieve this?

Which action should you take?

Choose only one option

Blue-green deployment, where you deploy the new version alongside the old version and then switch traffic once the new version is validated.

Canary deployment, where you gradually roll out the new version to a small subset of users and monitor its performance before expanding the rollout.

Rolling deployment, where you update containers one by one, ensuring minimal downtime but potentially exposing users to intermediate states.

Recreate deployment, where you terminate all existing pods and create new ones with the updated container image, leading to a brief downtime.

Question 2: You are experiencing intermittent network latency issues between your application components deployed across multiple regions in the cloud. How do you diagnose and resolve this problem?

Which action should you take?

Choose only one option

Utilize network monitoring tools and services provided by your cloud provider to analyze network traffic patterns and identify potential bottlenecks or congestion points.

Implement a global load balancer or content delivery network (CDN) to distribute traffic across regions and optimize network routing for improved performance.

Leverage network peering or dedicated connections between regions to reduce latency and improve network throughput for inter-region communication.

Optimize application code and data access patterns to minimize network traffic and reduce dependencies on cross-region communication.

Question 3: 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.

All of the above.

Question 4: You are experiencing challenges managing the complexity and dependencies of a large IaC codebase. How do you improve code maintainability, reusability, and collaboration among team members?

Which action should you take?

Choose only one option

Break down monolithic IaC configurations into smaller, modular components, promoting reusability and separation of concerns.

Adopt a consistent coding style and naming conventions for IaC resources and variables to enhance readability and maintainability.

Implement a code review process with clear guidelines and checklists to ensure code quality and consistency.

Leverage collaboration tools and platforms to facilitate communication and knowledge sharing among team members working on the IaC codebase.

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 responsible for ensuring the security and compliance of your organization's cloud infrastructure. How do you implement continuous monitoring and auditing practices to proactively identify and address potential risks or misconfigurations?

Which action should you take?

Choose only one option

Utilize cloud security posture management (CSPM) tools to continuously monitor and assess your cloud infrastructure for misconfigurations, vulnerabilities, and compliance violations.

Implement automated security checks and controls within your CI/CD pipeline to identify and address security issues early in the development process.

Conduct regular security audits and penetration testing to proactively identify and remediate weaknesses in your cloud environment.

Leverage cloud-native logging and monitoring services to collect and analyze security-related events and logs, enabling threat detection and incident response.
