Which feature will require the use of a named standard ACL rather than a numbered standard ACL?

Question:
Which feature will require the use of a named standard ACL rather than a numbered standard ACL?

• the ability to filter traffic based on a specific protocol
• the ability to filter traffic based on an entire protocol suite and destination
• the ability to specify source and destination addresses to use when identifying traffic
• the ability to add additional ACEs in the middle of the ACL without deleting and re-creating the list

Explanation: Standard ACLs (whether numbered or named) only filter on the source IP address. Having a named ACL makes it easier at times to identify the purpose as well as modify the ACL.
