## Question Bank

- [Answer these in your notebook. Do not rush.  What is the difference between a symptom and a root cause?  List the 6 steps of the evidence-first workflow.  Name 3 daily DBA checks.  Why is rollback planning mandatory?  What does “validate” mean after a change?  Why is changing 10 settings at once risky?  What should a professional incident update include?
