Which two conditions would cause a router to drop a packet? (Choose two.)

  • The ACL that is affecting the packet does not contain at least one deny ACE.

  • No routing table entry exists for the packet destination, but the packet matches a permitted address in an outbound ACL.

  • No outbound ACL exists on the interface where the packet exits the router.

  • No inbound ACL exists on the interface where the packet enters the router.

  • The packet source address does not match the source as permitted in a standard inbound ACE.

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

  • Multiple ACLs per protocol and per direction can be applied to an interface.

  • If a single ACL is to be applied to multiple interfaces, it must be configured with a unique number for each interface.

  • The most specific ACL statements should be entered first because of the top-down sequential nature of ACLs.

  • If an ACL contains no permit statements, all traffic is denied by default.

  • Standard ACLs are placed closest to the source, whereas extended ACLs are placed closest to the destination.

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

  • A packet can either be rejected or forwarded as directed by the ACE that is matched.

  • 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.

  • An implicit deny any rejects any packet that does not match any ACE.

  • All traffic is denied.

  • All traffic is permitted.

  • The ACL does not perform as designed.

  • The ACL will analyze traffic after it is routed to the outbound interface.
