問題文
A PB-TNC session runs over a half-duplex PT connection and now sits in the Decided state, reached when the Posture Broker Server sent its RESULT batch. The policy on the server has changed since then, and the Posture Broker Server wants a fresh exchange with the same endpoint. Which pair fits the standing that a CLOSE batch sent ahead of the connection going down holds and the step that the Posture Broker Server takes from here?
