Your question is On-Prem Security Architecture. 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).
Describe the architecture of an on-premises solution you have built, including how you handle security controls and access.
Explain the major components, trust boundaries, identity and authorization model, network controls, secrets handling, logging, and how you verified the controls worked. Be prepared to discuss one failure mode or security incident and how access was contained and restored.
