Security policy rules - ✔✔are applied to zones (not interfaces) to allow or deny traffic, apply QoS,
perform NAT, apply security profiles, or set logging parameters.



primary zone types - ✔✔Tap, Layer 2, Layer 3, Tunnel, and Virtual Wire are all



External zone - ✔✔only on some firewall models, allows traffic to pass between virtual systems when
multiple virtual systems are configured on the same firewall.



Ethernet interface types - ✔✔Tap, Virtual Wire, Layer 2, Layer 3, and HA are all



Decrypt Mirror - ✔✔traffic from a firewall to be copied and sent to a traffic collection tool that can
receive raw packet captures, sent to a data loss prevention (DLP) service.



Log card - ✔✔PA-7000 Firewalls only, port performs log forwarding for syslog, email, Simple Network

the traffic that the port receives



Layer 3 Interfaces - ✔✔routes traffic between multiple interfaces. A Virtual Router object must exist for
the firewall to route traffic between interfaces.

and duplex settings



Layer 3 Subinterfaces - ✔✔possess the same capabilities and features as Layer 3 interfaces, interfaces
are assigned to 802.1Q VLANs



Virtual routers - ✔✔routes to remote subnets either by the manual addition of static routes or the
