What are two characteristics of a stateful firewall? (Choose two.)

  • uses connection information maintained in a state table
  • uses static packet filtering techniques
  • analyzes traffic at Layers 3, 4 and 5 of the OSI model
  • uses complex ACLs which can be difficult to configure
  • prevents Layer 7 attacks

Explanation: Stateful firewalls are the most versatile and the most common firewall technologies in use. Stateful firewalls provide stateful packet filtering by using connection information maintained in a state table. Stateful filtering is a firewall architecture that is classified at the network layer. It also analyzes traffic at OSI Layers 4 and 5.​ Stateful firewalls cannot prevent application layer attacks because they do not examine the actual contents of an HTTP connection.
