An application-aware firewall inspects network traffic at the highest level of the OSI model, including application layer protocols, compared to a traditional stateful packet inspection firewall that only inspects up to the transport layer. The other options, DMZ firewall and stateless firewall, do not necessarily inspect at a higher level than traditional firewalls. Upper-layer firewall is not a commonly used term in the industry.
