I vaguely remember that the system-cpu-policer does aggregate traffic, but I’m not confident about how it interacts with line cards.

I feel like D could be the false statement, but I can't recall if both types of policers can actually be used together.

I think I came across a similar question in practice that mentioned hierarchical policing, so I’m leaning towards A being true.

I remember studying about CPM-filter policers, but I'm not entirely sure if the system-cpu-policer is hardware-based or not.
