A network administrator is configuring an ACL to restrict access to certain servers in the data center. The intent is to apply the ACL to the interface connected to the data center LAN. What happens if the ACL is incorrectly applied to an interface in the inbound direction instead of the outbound direction?

  1. All traffic is denied.
  2. All traffic is permitted.
  3. The ACL does not perform as designed.*
  4. The ACL will analyze traffic after it is routed to the outbound interface.

Explanation:
Always test an ACL to ensure that it performs as it was designed. Applying an ACL that is applied using the ip access-group in command instead of using the ip access-group out command is not going to work as designed.
