Which two statements describe appropriate general guidelines for configuring and applying ACLs? (Choose two.)

  • Standard ACLS are placed closest to the source, whereas extended ACLS are placed closest to the destination.
  • If an ACL contains no permit statements, all traffic is denied by default.
  • The most specific ACL statements should be entered first because of the top-down sequential nature of ACLs.
  • If a single ACL is to be applied to multiple interfaces, it must be configured with a unique number for each interface.
  • Multiple ACLS per protocol and per direction can be applied to an interface.

Explanation: An interface can only have one ACL per direction. Standard ACLs filter only on the source address, so they are normally placed closest to the destination. Extended ACLs filter on source and destination addresses and port numbers. They are commonly placed closest to the source to reduce traffic across the network or networks. A single ACL can be applied to multiple interfaces.
