A router has been configured as a classic firewall and an inbound ACL applied to the external interface. Which action does the router take after inbound-to-outbound traffic is inspected and a new entry is created in the state table?

  • When traffic returns from its destination, it is reinspected, and a new entry is added to the state table.
  • The internal interface ACL is reconfigured to allow the host IP address access to the Internet.
  • The entry remains in the state table after the session is terminated so that it can be reused by the host.
  • A dynamic ACL entry is added to the external interface in the inbound direction.

Explanation: The traffic flow from the internal network to the public network is commonly inspected. The traffic flows cause dynamic entries to be added to the external interface for inbound traffic so that traffic that originates from the internal network going to the public network is allowed to return to the internal source.
