Preview Questions DevOps | Role Specific Skill

Question 1: 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 2: You are responsible for monitoring a critical production system that handles sensitive customer data. How do you balance the need for comprehensive monitoring with the importance of data privacy and security?

Which action should you take?

Choose only one option

Implement data anonymization and masking techniques to protect sensitive customer information while still enabling effective monitoring and troubleshooting.

Utilize security-focused monitoring tools that can detect and alert on potential data breaches or unauthorized access attempts.

Enforce strict access controls and encryption for monitoring data to prevent unauthorized access or disclosure.

Conduct regular security audits and vulnerability assessments of your monitoring infrastructure to identify and address potential weaknesses.

Question 3: You are tasked with improving the performance and efficiency of your monitoring infrastructure, which is struggling to keep up with the increasing volume and complexity of data generated by your systems. What strategies do you employ to address this challenge?

Which action should you take?

Choose only one option

Upgrade your monitoring infrastructure's hardware and software components to handle the increased load and data volume, ensuring sufficient processing power and storage capacity.

Optimize data collection and aggregation processes, leveraging techniques such as sampling, filtering, and compression to reduce the amount of data transmitted and stored.

Implement a distributed monitoring architecture, partitioning data collection and analysis across multiple nodes or regions to improve scalability and fault tolerance.

Evaluate and potentially adopt a cloud-native monitoring solution that can leverage the elasticity and scalability of the cloud to handle fluctuating workloads.

Question 4: You are tasked with optimizing the cost of your cloud infrastructure while maintaining performance and reliability. What approach do you take?

Which action should you take?

Choose only one option

Right-size instances based on actual usage patterns and leverage auto-scaling to adjust resources based on demand.

Utilize reserved instances or savings plans for predictable workloads to get significant discounts on compute costs.

Identify and eliminate unused or underutilized resources, such as idle instances or unattached storage volumes.

Implement a cost allocation and chargeback model to increase cost awareness and accountability among teams and projects.

Question 5: You notice a significant increase in build times. What's your approach to investigate?

Which action should you take?

Choose only one option

Analyze the build logs to identify any bottlenecks or performance issues.

Profile the build process to pinpoint the most time-consuming steps.

Optimize the build scripts and configurations to improve efficiency.

Upgrade the build infrastructure to handle the increased load.

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.
