A standard access control list has been configured on a router and applied to interface Serial 0 in an outbound direction. No ACL is applied to Interface Serial 1 on the same router.
What will happen when traffic being filtered by the access list does not match the configured ACL statements for Serial 0?
A.
The source IP address is checked, and, if a match is not found, traffic is routed out interface Serial 1.
B.
The resulting action is determined by the destination IP address.
C.
The resulting action is determined by the destination IP address and port number.
D.
The traffic is dropped.
Explanation:
Tricky one, this one. Just remember that the ACL identifies any traffic that is either
Permitted or Denied. If nothing matches, then the implicit DENY included in every ACL
kicks in, and the traffic is dropped.
