[OSL | CCIE_RS] Shape vs Police question

[Derek Winchester]

Someone asked me a very good question yesterday and I am still
confused if I gave him the correct answer. He gave me a scenario that
states that he has to limit all IP Precedence 3 traffic out of an
interface to 256k, but he cannot use policing or rate-limiting. My
answer was to use shaping. But from my experience, doesn't the word
"limit" negates that as a possible answer? Even though you can use
shaping to limit, I was always under the impression when studying for
the CCIE that if they use the word limit that means no shaping. Can
someone help ease my conscience?
