Your question is Manage a Critical Security Incident. 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).
You are responding to a critical security incident that is actively affecting a production system, and senior leaders are asking for frequent updates while the technical picture is still changing. You need to contain the issue, coordinate the response, and keep stakeholders informed without creating panic or overcommitting before facts are confirmed.
Tell me about a time you had to manage a critical incident while keeping stakeholders calm.
