Preview Questions DevOps | Role Specific Skill

Question 1: You are responsible for managing secrets and sensitive configuration data within your configuration management system. How do you ensure the security and confidentiality of this information while maintaining ease of use and accessibility for authorized personnel?

Which action should you take?

Choose only one option

Encrypt sensitive data at rest and in transit using strong encryption algorithms and key management practices, ensuring that only authorized personnel have access to the decryption keys.

Utilize a secrets management solution to store and retrieve sensitive data securely, integrating it seamlessly with your configuration management tools and workflows.

Implement role-based access control and least privilege principles to restrict access to sensitive configuration data based on user roles and responsibilities.

Regularly audit and review access logs and configuration changes to detect any unauthorized access or suspicious activity related to sensitive data.

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'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 4: Your team is adopting a new CI/CD tool. How do you ensure security is integrated into the pipeline from the start?

Which action should you take?

Choose only one option

Configure the tool with default security settings and rely on its built-in security features.

Perform a security assessment of the tool before integrating it into the pipeline.

Implement security scanning and testing as part of the pipeline stages.

Train the team on secure coding practices and pipeline configuration.

Question 5: A new feature deployment caused a critical production outage. What is your immediate action?

Which action should you take?

Choose only one option

Roll back the deployment to the previous stable version.

Quickly try to identify and fix the issue in production.

Pause all further deployments until the issue is resolved.

Communicate the issue to stakeholders and provide an estimated time for resolution.

Question 6: You are building a Docker image for your application, but the image size is very large, impacting build and deployment times. How do you optimize the image size without sacrificing functionality?

Which action should you take?

Choose only one option

Utilize a smaller base image, such as Alpine Linux, to reduce the overall image size.

Leverage multi-stage builds to separate build-time dependencies from runtime dependencies, resulting in a smaller final image.

Minimize the number of layers in the Docker image by combining commands and optimizing the Dockerfile instructions.

Analyze the contents of the image using tools like dive to identify and remove any unnecessary files or dependencies.
