Consider using an automation tool of some kind (Terraform, Pulumi, Ansible, cli, etc) when studying for a cloud cert (Azure, AWS, GCP, etc.). This has many benefits: You get to learn a tool you’ve never had the chance to use before, so you’d effectively be learning two things at once. You’re getting yourself hands on troubleshooting experience. You’re almost guaranteed to delete all the resources you’ve created with them. I insist on ‘almost’: you still have to remember to run the destroy command at the end of the day (happened to me).
