Which statement describes a difference between the operation of inbound and outbound ACLs?

  • In contrast to outbound ALCs, inbound ACLs can be used to filter packets with multiple criteria.
  • Inbound ACLs can be used in both routers and switches but outbound ACLs can be used only on routers.
  • Inbound ACLs are processed before the packets are routed while outbound ACLs are processed after the routing is completed.
  • On a network interface, more than one inbound ACL can be configured but only one outbound ACL can be configured.
    Answers Explanation & Hints:

    With an inbound ACL, incoming packets are processed before they are routed. With an outbound ACL, packets are first routed to the outbound interface, then they are processed. Thus processing inbound is more efficient from the router perspective. The structure, filtering methods, and limitations (on an interface, only one inbound and one outbound ACL can be configured) are the same for both types of ACLs.
