Summary

Great! We just completed the Heat exam objective section of our COA prep. Remember that you can complete Horizon objectives on both the dashboard and CLI, but updating an existing stack is much easier on the CLI thanks to the --existing flag. Don't forget to always try to use UUIDs of virtual resources for Heat parameters. There may be multiple resources with the same name and UUIDS allow us to be specific. Do not be overly concerned with building Heat templates from scratch or overly complex Heat template scenarios. If you can kick a stack and provide the appropriate parameters, you'll be good to go! Now that we have completed all service-related objectives in the exam, let's move on to the final section: troubleshooting!
