I'm not so sure about that. Wouldn't C) Slow Start be a better option? It could help reduce the number of connections by gradually increasing the connection rate.

I'm not sure, but I think Reset on timeout could also be a good option to consider.

I agree with Gearldine, setting an idle timeout can help clear stale TCP connections and reduce memory utilization.

Hmm, I think the answer is B) Reset on timeout. This option will forcefully close stale TCP connections, which should help reduce memory utilization on the LTM device.
