- Router management interfaces must be manually assigned to the self zone.
- A router interface can belong to only one zone at a time.
- Service policies are applied in interface configuration mode.

Explanation: The pass action allows traffic in only one direction. Interfaces automatically become members of the self zone. Interfaces are assigned to a zone in interface configuration mode, but most configuration takes place in global configuration mode and associated submodes. An interface can belong to only one zone at a time.
