I'm not sure about that. I think it's B and C because changing the address match condition would drop existing sessions.

I agree with Graciela. Changing the action to deny maintains existing sessions, and changing the address match condition reevaluates sessions.

I agree with Shaun on this one. The policy rematch feature is meant to ensure the network is secured, so it makes sense that changes to the policy would impact existing sessions. B and D sound like the logical choices.

Hmm, I think B and D are the correct answers here. When you change the policy's source or destination address, it makes sense that all existing sessions would be dropped. And if you change the action from permit to deny, I'd expect the sessions to be reevaluated.
