An IPv4 ACL applied to an interface appears to allow all incoming traffic. Which two misconfigurations could cause this behavior? (Choose two.)

An IPv4 ACL processes statements sequentially and stops at the first match. If a permit statement is too broadly defined (e.g., permit ip any any), it will match all traffic and allow it, effectively bypassing subsequent, more specific deny statements. Similarly, if a specific permit statement is placed too high in the access list, it might match traffic that a later, more restrictive deny statement was intended to block. The packets failing to match any permit statement would result in all traffic being denied due to the implicit deny any at the end of every ACL, not all traffic being allowed. A matching deny statement being too high would block traffic, not allow it. An empty ACL also implicitly denies all traffic.
