Which two statements about traffic policing are true?

Policing should be performed as close to the source as possible to prevent excess traffic from consuming bandwidth unnecessarily across the network. If policing is done closer to the destination, the excess traffic has already traversed a significant portion of the network, potentially impacting other services. Policing drops traffic that exceeds the configured rate, rather than queuing or delaying it. This is a key distinction from traffic shaping, which buffers and delays excess traffic to smooth out the traffic flow. Policing does not adapt to network congestion by queuing; it strictly enforces the rate and discards non-conforming packets.
