Preview Questions DevOps | Role Specific Skill

Question 1: 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 2: You're building a CI/CD pipeline on Google Cloud Platform (GCP). You need a service to automate the build, test, and deployment of your application code. Which service would you choose?

Which action should you take?

Choose only one option

Google Cloud Build

Google App Engine

Google Kubernetes Engine

Google Compute Engine

Question 3: You're deploying a new application version using Ansible, but the deployment is failing on some servers due to incompatible operating system versions. How do you handle this?

Which action should you take?

Choose only one option

Modify the Ansible playbook to check the operating system version and skip deployment on incompatible servers.

Update the operating system on the affected servers to a compatible version before proceeding with the deployment.

Create separate Ansible playbooks for different operating system versions to ensure compatibility.

Roll back the deployment and investigate the root cause of the incompatible operating system versions.

Question 4: 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 5: You are troubleshooting a production issue where a containerized application is experiencing high memory usage and frequent OutOfMemory (OOM) errors. How do you diagnose and resolve this problem?

Which action should you take?

Choose only one option

Increase the memory limits allocated to the container to provide more resources and prevent OOM errors.

Profile the application's memory usage inside the container to identify memory leaks or inefficient memory management practices.

Optimize the application code to reduce memory footprint and improve memory utilization.

Implement resource monitoring and alerting to proactively detect and address potential memory issues before they cause OOM errors.

Question 6: Your team is experiencing frequent pipeline failures due to inconsistent environment configurations between development, staging, and production. How do you address this?

Which action should you take?

Choose only one option

Implement configuration management tools to enforce consistency across all environments.

Standardize environment setup scripts and configurations to minimize variations.

Utilize containerization to package applications with their dependencies, ensuring consistent execution across environments.

Introduce automated environment provisioning and configuration tools to eliminate manual errors.
