Your question is Rolling Back a Failed Deployment. 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).
Tell me about a time you had to roll back a failed infrastructure deployment in production. Walk me through how you detected the issue, decided to roll back, communicated during the incident, and what you changed afterward to reduce the chance of it happening again.
