This episode explains the importance of verifying that a system is fully functional after implementing a fix. We discuss running validation tests, confirming service availability, and ensuring performance metrics are within acceptable ranges. Functional verification also involves checking related systems that may have been indirectly affected by the change.

Practical examples include confirming that all nodes in a cluster are online after maintenance or validating database queries after a storage reconfiguration. Troubleshooting considerations involve re-running baseline tests, gathering user feedback, and reviewing monitoring tools for anomalies. Mastery of post-fix verification ensures candidates can confirm the problem is resolved and that the system is stable for production use.
