Which mechanism is often configured on the edges of a network to control the maximum rate of traffic that is sent or received on an interface and to classify the traffic into priority levels or class of service?

1. The answer is linked to he question “sent or received”

   Shaping implies the existence of a queue and of sufficient memory to buffer delayed packets, while policing does not. Queueing is an outbound concept; packets going out an interface get queued and can be shaped. ** Only policing can be applied to inbound traffic on an interface **

2. Quote out of CIPTV1 book, page 313
   “Shaping usually occurs at the edge of a network and can be applied to an interface in an output direction”
   So based on the above, answer is C

3. traffic policing limits traffic transmission by dropping packets, it is more suitable for high-speed links such as LAN or Multiprotocol Label Switching (MPLS) links.
   Traffic shaping is more suitable for lower-speed links such as Multilink PPP (MLP) and Frame Relay, as it buffers excess traffic.

   1. but looks like the answer must be B (shaping)
