Preview Questions DevOps | Role Specific Skill

Question 1: Your team is adopting a new configuration management tool to replace an existing legacy system. You are concerned about potential compatibility issues and the impact on existing configurations and workflows. How do you mitigate these risks and ensure a smooth transition?

Which action should you take?

Choose only one option

Conduct a thorough evaluation of the new tool's capabilities and compatibility with existing infrastructure, applications, and processes, identifying potential challenges and risks.

Develop a detailed migration plan, including data migration, configuration conversion, and testing procedures, with clear timelines and milestones.

Establish a dedicated migration team with expertise in both the legacy and new configuration management tools to facilitate the transition and address any issues that arise.

Implement a phased migration approach, starting with non-critical components and gradually expanding to more critical systems, closely monitoring the impact and addressing any issues before proceeding.

Question 2: You are tasked with improving the observability and monitoring of your CI/CD pipeline. How do you achieve this goal?

Which action should you take?

Choose only one option

Integrate logging and monitoring tools into the pipeline to collect and analyze pipeline execution data.

Implement real-time dashboards and visualizations to track pipeline health and performance metrics.

Set up alerting mechanisms to notify relevant stakeholders of pipeline failures or anomalies.

Correlate pipeline metrics with application performance data to identify potential bottlenecks and areas for improvement.

Question 3: You've made a change to a Terraform configuration file, but after applying it, you realize it introduced an unintended side effect. How do you quickly and safely revert the change?

Which action should you take?

Choose only one option

Use Terraform's terraform destroy command to destroy the affected resources and then reapply the previous configuration.

Manually revert the change in the Terraform configuration file and then run terraform apply to apply the corrected configuration.

Utilize Terraform's state file to identify the specific changes made and then use terraform taint and terraform apply to force recreation of the affected resources.

Temporarily comment out the problematic part of the Terraform configuration and reapply it to see if the issue is resolved.

Question 4: You're using CloudFormation to manage your AWS infrastructure. You notice that some resources are not being updated after you make changes to the CloudFormation template. What could be the cause?

Which action should you take?

Choose only one option

The CloudFormation stack might be in a failed state due to previous errors, preventing further updates.

The changes you made to the template might not trigger an update for the specific resources.

There might be a dependency issue in the template that's preventing the resources from being updated in the correct order.

The CloudFormation service might be experiencing temporary issues or outages.

Question 5: You are leading a team that is responsible for managing a complex and rapidly evolving cloud infrastructure. How do you stay ahead of emerging security threats and ensure that your security practices remain effective in this dynamic environment?

Which action should you take?

Choose only one option

Stay informed about the latest security trends, vulnerabilities, and attack vectors through continuous learning and research.

Participate in industry forums, conferences, and communities to exchange knowledge and best practices with other security professionals.

Conduct regular threat modeling exercises to identify and assess potential risks to your cloud infrastructure and applications.

Proactively evaluate and adopt new security tools and technologies to enhance your defenses and address emerging threats.

Question 6: You observe a growing trend of configuration drift across your infrastructure, leading to inconsistencies and potential security risks. How do you proactively address this issue and maintain configuration integrity?

Which action should you take?

Choose only one option

Implement automated configuration drift detection and remediation mechanisms to identify and rectify deviations from desired state configurations.

Strengthen change management processes, requiring thorough reviews and approvals before applying configuration changes.

Utilize configuration version control and rollback capabilities to track changes and revert to previous states if necessary.

Implement continuous compliance monitoring to ensure adherence to security policies and industry regulations.
