Which four (4) factors does a stateless firewall look at to determine if a packet should be allowed pass?

• if the packet belongs to an open session

• the destination port

• the destination IP address

• the source IP address

• the service or protocol used

Can a single firewall conduct both a stateless and stateful inspection?

• Yes but not on the same packet. A decision is made which type of inspection will be most effective on a packet-by-packet bases.

• No, stateless and stateful firewalls are distinctly different and used for different purposes.

• No, the latency created by a double inspection is too great to be practical.

• Yes, the stateless inspection is conducted first and then a stateful inspection is done.
