What is the effect of adding a permit any statement to Access List 11?

• A. Allows all traffic not restricted by the list
• B. Denies all traffic
• C. Allows only specified hosts
• D. Blocks all traffic

Answer: (A)

Access Control Lists are processed from top to bottom, and the first rule that matches a packet decides whether it’s allowed or blocked. If no rule matches, there’s an implicit deny at the end. Adding a catch-all statement like “permit any” means any traffic that hasn’t been matched by earlier rules will be allowed. So it effectively lets through all traffic that isn’t already restricted by the previous statements. It doesn’t override explicit denies above it—those still apply—but anything not previously matched is now permitted. This is why the best description is that it allows all traffic not restricted by the list.
