Preview Questions DevOps | Role Specific Skill

Question 1: Your team is adopting IaC principles, and you're tasked with converting existing manual infrastructure provisioning processes into code. What's your approach?

Which action should you take?

Choose only one option

Carefully document the existing manual processes and translate them into IaC code, ensuring accuracy and completeness.

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

Utilize IaC tools to generate code snippets based on existing infrastructure configurations, and then refine them.

Research and experiment with different IaC approaches and patterns to find the most suitable solution for your team's needs.

Question 2: You receive an alert about suspicious activity on one of your production servers. What is your initial response?

Which action should you take?

Choose only one option

Immediately isolate the server from the network to prevent further compromise.

Review the logs and system activity to understand the nature of the suspicious activity.

Contact the security team to report the incident and request assistance.

Restart the server to clear any potential malicious processes.

Question 3: You've deployed an application to multiple regions on AWS to improve performance and availability for users around the world. You now need a way to distribute traffic to the closest region for each user. What service would you use?

Which action should you take?

Choose only one option

AWS Global Accelerator

AWS CloudFront

AWS Route 53

AWS Elastic Load Balancing

Question 4: You have containerized an application, but it's running slower inside the container compared to its performance on a bare-metal server. How do you troubleshoot and improve its performance within the container?

Which action should you take?

Choose only one option

Increase the resource limits (CPU and memory) allocated to the container to provide more processing power.

Profile the application's performance inside the container to identify potential bottlenecks or resource contention issues.

Optimize the container image by reducing its size and minimizing unnecessary layers or dependencies.

Investigate potential network latency or I/O bottlenecks that might be affecting the container's performance.

Question 5: Your organization is experiencing a high rate of false-positive alerts, leading to alert fatigue and delayed response to critical issues. How do you improve alert accuracy and reduce noise in your monitoring system without compromising on critical issue detection?

Which action should you take?

Choose only one option

Fine-tune alert thresholds and sensitivity based on historical data and baseline performance, ensuring that alerts are triggered only for significant deviations from expected behavior.

Implement alert correlation and suppression rules to group related alerts and avoid redundant notifications, focusing on the root cause of issues rather than individual symptoms.

Leverage machine learning and anomaly detection techniques to identify patterns and filter out false positives, while still being able to detect new or unexpected anomalies.

Conduct regular reviews and audits of your alerting rules and thresholds, involving subject matter experts from different teams to ensure their effectiveness and relevance.

Question 6: The deployment process is taking too long, impacting the team's agility. How do you address this?

Which action should you take?

Choose only one option

Break down the monolithic application into smaller, independently deployable microservices.

Optimize the deployment scripts and configurations to streamline the process.

Implement parallel deployment strategies to deploy multiple components simultaneously.

Invest in a more robust deployment infrastructure to handle larger deployments.
