Your question is Post-Incident Actions After Peak Failure. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
A software update caused an application to fail during peak times. What would you do after the incident was analyzed?
Explain the practical steps you would take after root-cause analysis, including containment, rollback or remediation, validation, communication, monitoring, and prevention. Address both availability impact and the possibility that the update introduced a security weakness.
