Refer to the Exhibit.
Traffic is flowing through the policer as shown in the exhibit. The traffic has a throughput rate of 3
Mbps, and the burst size counter is at 1.5 MB. How is traffic affected?
A.
Traffic has its PLP set to low.
B.
Traffic has its PLP set to medium-low.
C.
Traffic has its PLP set to medium-high.
D.
Traffic has its PLP set to high.

D is correct
Red—Traffic that exceeds the bandwidth limit and burst size for peak traffic (PIR and PBS). For a red traffic flow, two-rate TCM marks packets with an implicit loss priority of high and, optionally, discards the packets.
Mody, the PIR is 5Mb/s so it is not exceeded since the traffic throughput is 3Mb/s
Green—Traffic that conforms to the bandwidth limit and burst size for guaranteed traffic (CIR and CBS). For a green traffic flow, two-rate TCM marks the packets with an implicit loss priority of low and transmits the packets.
Yellow—Traffic that exceeds the bandwidth limit or burst size for guaranteed traffic (CIR or CBS) but not the bandwidth limit and burst size for peak traffic (PIR and PBS). For a yellow traffic flow, two-rate TCM marks packets with an implicit loss priority of medium-high and transmits the packets.
Red—Traffic that exceeds the bandwidth limit and burst size for peak traffic (PIR and PBS). For a red traffic flow, two-rate TCM marks packets with an implicit loss priority of high and, optionally, discards the packets.
