Summary

So there we have it! In this section, we covered some general OpenStack troubleshooting skills that will prepare you for the COA exam. Remember that the troubleshooting domain covers only about 13% of the exam, so don't expect many questions on this content.

And lastly, we ended the chapter with some very basic MySQL/MariaDB skills, including showing tables of specific databases, backing up, and restoring databases.
