Which statement describes the default network access control on an ASA firewall device?
- Inbound traffic from the DMZ network to the inside network is allowed.
- Inbound traffic from the outside network to the DMZ network is allowed.
- Returning traffic from the outside network to the inside network is allowed.
- Outbound traffic from the inside network to the outside network is allowed without inspection.
Explanation: With the security levels properly configured on the inside, outside, and DMZ networks, outbound traffic is allowed and inspected by default. Hosts on the higher security interface can access hosts on a lower security interface. However, traffic that is initiated from a lower level security interface and going into a higher security level interface, is denied by default. Returning traffic is allowed because of stateful packet inspection.
