How would you answer an interview scenario involving secrets in containers in Container Security?

For an interview scenario involving secrets, I would first clarify the business goal, scale, constraints, and the failure or quality attribute the interviewer wants to explore. In this scenario, a database password was accidentally added during docker build. Explain why deleting it in a later layer is insufficient. I would then explain the main alternatives and tradeoffs, identify likely failure modes, and describe how I would validate the solution through testing, observability, security controls, and recovery or rollback planning.
