Question:
Which three statements describe ACL processing of packets? (Choose three.)

  • An implicit deny any rejects any packet that does not match any ACE.
  • A packet can either be rejected or forwarded as directed by the ACE that is matched.
  • A packet that has been denied by one ACE can be permitted by a subsequent ACE.
  • A packet that does not match the conditions of any ACE will be forwarded by default.
  • Each statement is checked only until a match is detected or until the end of the ACE list.
  • Each packet is compared to the conditions of every ACE in the ACL before a forwarding decision is made.

Explanation: When a packet comes into a router that has an ACL configured on the interface, the router compares the condition of each ACE to determine if the defined criteria has been met. If met, the router takes the action defined in the ACE (allows the packet through or discards it). If the defined criteria has not been met, the router proceeds to the next ACE. An implicit deny any statement is at the end of every standard ACL.
