Your question is PCB Ground Plane Cutout Reasoning. 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).
Explain why the ground plane of a PCB has a cutout where a trace enters a connector at Hp Iq.
Treat this as a practical PCB review question. Explain the electrical reasons a designer might introduce the cutout, the risks if it is too large or misplaced, and how you would validate the design with simulation and lab measurements. State clearly that the correct explanation depends on the connector geometry, signal speed, stackup, and whether the signal is single-ended or differential.
