D.

E.
when rate limiting is applied
Explanation:
Stateful inspection monitors incoming and outgoing packets over time, as well as the state of
the connection, and stores the data in dynamic state tables. This cumulative data is
evaluated, so that filtering decisions would not only be based on administrator-defined rules,
but also on context that has been built by previous connections as well as previous packets
belonging to the same connection.
Entries are created only for TCP connections or UDP streams that satisfy a defined security
policy.
In order to prevent the state table from filling up, sessions will time out if no traffic has passed
for a certain period. These stale connections are removed from the state table.
