In which situation is it acceptable for an IT professional to access corporate secrets?

when she or she is the last hope of the surveillance or the intelligence

The correct answer is - continental slope.

The ocean floor is divided into multiple parts. One of those parts is the continental slope. The continental slope is the zone between the continental shelf, and the abyssal plain. The continental shelf is a relatively flat part of the ocean, shallow, and it is the closest to the shores, while the abyssal plain is a relatively flat zone of the ocean, but it is very deep and far away from the shores. The zone/part that separates them both, or rather transitions from the one to the another, is the continental slope, which is a very steep part of the ocean, that descends very sharply, and goes from very shallow waters to very deep waters in a very small space.
