In which configuration would an outbound ACL placement be preferred over an inbound ACL placement?
when a router has more than one ACL
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
when an outbound ACL is closer to the source of the traffic flow
when the ACL is applied to an outbound interface to filter packets coming from multiple inbound interfaces before the packets exit the interface
