Your question is Linux Process Termination. 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 what the command kill -9 does on Linux and when you would use it in a QA automation context at NVIDIA.
Keep your answer focused on what signal 9 means, what the kernel does, and what it does not allow the target process to do. Then explain when force-killing is acceptable in test automation versus when it can hide a real defect.
Assume Linux-based test runners and automation jobs only.
