Question 571 · 856 in bank
While troubleshooting a firewall configuration, a technician determines that a "deny any" policy should be added to the bottom of the ACL. The technician updates the policy, but the new policy causes several company servers to become unreachable. Which of the following actions would prevent this issue?
Show answer
Answer: A
Explanation
At first I thought B but I realize how impractical that would be in the real world. Unlike applications, you cannot deploy firewall policies in a test environment as the rules are declarative (you know something is getting blocked even if you don't know what exactly that will be). So, I'd go with A because the Change Advisory Board needs to go through the request, gauge the risks, rollback actions and points etc.
