JNCIA-Junos: Juniper Networks Certified Associate – Junos (2022) — Question 51

What is the default action for packets not matching a firewall filter?

Answer options

• A. The packet will be silently discarded.
• B. The packet will be accepted.
• C. The packet will be rejected.
• D. The packet will be ignored.

Correct answer: A

Explanation

The correct answer is A, as the default behavior for packets that do not match a firewall filter is to silently discard them without any notification. Options B and C indicate acceptance and rejection respectively, which do not represent the default behavior. Option D suggests the packets are ignored, which is not the correct terminology in firewall operations.
