In which configuration would an outbound ACL placement be preferred over an inbound ACL placement?
- when the ACL is applied to an outbound interface to filter packets coming from multiple inbound interfaces before the packets exit the interface
- when a router has more than one ACL
- when an outbound ACL is closer to the source of the traffic flow
- when an interface is filtered by an outbound ACL and the network attached to the interface is the source network being filtered within the ACL
Explanation: An outbound ACL should be utilized when the same ACL filtering rules will be applied to packets coming from more than one inbound interface before exiting a single outbound interface. The outbound ACL will be applied on the single outbound interface.
