Which statement correctly 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.
Explanation: While the provided sources emphasize the importance of applying ACLs in the correct direction to achieve desired results,, they do not explicitly define the routing-to-filtering sequence.
However, in standard networking (which you may wish to verify independently), inbound ACLs filter packets immediately as they enter an interface before a routing lookup is performed. Conversely, outbound ACLs filter packets after the routing decision has determined the exit interface but before the packet is actually transmitted.
