https://www.cisco.com/c/en/us/td/docs/ios/12_2sb/feature/guide/cpp.html exceed-action action: Specifies the action to take on packets that exceed the rate limit violate-action action: Specifies the action to take on packets that continuously exceed the police rate limit. "continuously exceeds" -> Hence, option C,E.

R1(config)#policy-map POLICY-CoPP R1(config-pmap)#class CLASS-CoPP-Management R1(config-pmap-c)#police 320000 conform-action transmit exceed-action transmit violate-action drop E. R1(config)#control-plane R1(config-cp)# service-policy input POLICY-CoPP One thing to take in mind , this is only half right. We here difine only CIR no PIR (Peak information rate), without PIR our violate-action drop means nothing. Command should look like this police 320000(CIR) 640000(PIR) conform-action transmit exceed-action transmit violate-action drop CIR= Committed Information Rate , PIR =Peak information Rate . This is what policing does , ensues speed under <CIR is guaranteed , values <PIR (sometimes transmit, short period) Values over PIR DROP .

consider "when it continuously exceeds", the word continuously mean there could be some extra buffer, but the extra buffer is limited.

Selected Answer: BE
With B.: When the traffic rate is below 320 Kbps the conform-action is to transmit the packet, when it exceeds 128 Kbps we will drop the packet. violate-action specifies the action to take on packets that violate the normal and maximum burst sizes (default normal burst size is 1500 bytes; maximum burst size in bytes depends on the platform) >> in our case drop for B and C. >>> It's not asking for bursts it's asking for continious....

not sure but CE my choise; cisco(config-pmap-c)#police 320000 conform-action transmit exceed-action tra cisco(config-pmap-c)#$00 conform-action transmit exceed-action transmit ? violate-action action when rate is greater than conform + exceed burst <cr> cisco(config-pmap-c)#$00 conform-action transmit exceed-action transmit v cisco(config-pmap-c)#$-action transmit exceed-action transmit violate-action ? drop drop packet

"continuously" would imply that occasionally exceeding 320kbps is ok. "exceed drop" will not allow it to ever go above it.

Not sure if the answer is BE or CE. The phrase in the question to watch for is: "continuously exceed". Does the phrase mean violate?

Continuously exceeding leads to violation. The answer is CE.

The question only refers to a conform CIR of 320Kbps, no PIR is mentioned so are you just assuming this is a dual bucket?
