Your question is Camera Degrees of Freedom. 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).
If you had a camera that needed to track or follow the motion of an object, what is the minimum number of degrees of freedom you should have, and what changes if the camera also needs to match the object's orientation?
