Click the Exhibit button. You have configured and applied the policer shown in the exhibit to your Junos device. Which statement is true in this scenario?
A.
Traffic exceeding the committed-burst size will be marked with a loss priority of high.
B.
Traffic exceeding the excess-burst size will be discarded.
C.
Traffic exceeding the committed-information-rate will be rate limited.
D.
Traffic exceeding the committed-burst size will be discarded.
actually, PLP is set to high, it does not guaranty that the packets would definitely be discarded. Hence the safest answer is C, anything beyond CIR is rate limited.
Answer is B. https://www.juniper.net/documentation/us/en/software/junos/routing-policy/topics/topic-map/policer-single-rate-three-color.html
"Red—Traffic that exceeds the burst size for peak traffic (EBS), single-rate marks packets with an implicit loss priority of high and, optionally, discards the packets." As in the question, this discard option is used, so B is the correct answer.
B is correct:
Red—Traffic that exceeds the burst size for peak traffic (EBS), single-rate marks packets with an implicit loss priority of high and, optionally, discards the packets.
B.

Because the optional action statement is included, it will take the more severe action of discarding packets in a red traffic flow.
The action configured is to discard the high queue, it is optional but dicard has been configured, so I still think B
