What is the effect of configuring an ACL with only ACEs that deny traffic?

Question:
What is the effect of configuring an ACL with only ACEs that deny traffic?

• The ACL will permit any traffic that is not specifically denied.
• The ACL will block all traffic.
• The ACL must be applied inbound only.
• The ACL must be applied outbound only.

Explanation: Because there is a deny any ACE at the end of every standard ACL, the effect of having all deny statements is that all traffic will be denied regardless of the direction in which the ACL is applied.
