1. You are responsible for managing the OpenStack control plane and ensuring all core services are running without failure. A user reports that OpenStack Compute (Nova) is not responding. Your task is to check the status of all OpenStack services on the control plane, restart any failed services, and verify that they are running correctly.

How would you achieve this?

2. As part of routine maintenance, you need to check and confirm whether the OpenStack Identity (Keystone) service is functional and responding correctly.

How would you verify the Keystone service's status, check if it is accessible via API, and restart it if necessary?

3. Your OpenStack cloud is experiencing intermittent failures, and you suspect issues with the RabbitMQ messaging service, which is critical for communication between OpenStack components.

How would you check the RabbitMQ service status, troubleshoot issues, and restart it if necessary?

4. You need to back up the OpenStack database before applying a system update.

How would you create a full backup of the OpenStack MariaDB database while ensuring minimal downtime?

5. You need to restore the OpenStack database from a previously created backup due to data corruption.

How would you restore the MariaDB database while ensuring the OpenStack services can access it correctly?

6. Your OpenStack control plane is experiencing performance degradation, and you suspect that some services are consuming excessive memory and CPU resources.

How would you identify resource-heavy OpenStack services, analyze their impact, and take corrective action?

7. An OpenStack environment is failing to start due to database connection errors.

How would you troubleshoot and restore database connectivity to ensure all OpenStack services can function properly?

8. Your OpenStack services fail to start after a system reboot.

How would you identify the cause of the failure and restore OpenStack services to full functionality?

9. You need to configure OpenStack services to automatically restart upon failure.

How would you modify systemd settings to ensure services restart without manual intervention?

10. An OpenStack deployment is failing due to a misconfiguration in the nova.conf file.

How would you identify and fix the configuration issue without disrupting the environment?

11. You have modified OpenStack configurations and need to apply the changes without restarting the services.

How can you reload configuration files dynamically to minimize service disruption?

12. A critical OpenStack control plane service (e.g., Neutron) is failing frequently.

How would you configure

systemd to automatically restart the service after failures while implementing a backoff delay?

13. You need to upgrade OpenStack packages while minimizing downtime.

What are the necessary steps to upgrade OpenStack services safely without disrupting active workloads?

14. Your OpenStack environment is running out of disk space.

How would you clean up old logs and temporary files while ensuring essential logs remain intact for troubleshooting?

15. You need to create an OpenStack database backup without stopping services.

How would you take a consistent backup while ensuring minimal disruption?

16. Your OpenStack database was corrupted, and you need to restore it from the latest backup while ensuring minimal downtime for the environment.

How would you perform a full restoration of the OpenStack database and ensure all services are using the restored data correctly?

17. Your OpenStack control plane is experiencing high CPU usage, which is affecting system performance.

How would you identify and mitigate CPU-intensive processes while ensuring critical services remain unaffected?
