JNCIA-Junos: Juniper Networks Certified Associate – Junos (2024) — Question 82

Which two statements about firewall filters are correct? (Choose two.)

Answer options

• A. Firewall filters can match Layer 7 parameters.
• B. Firewall filters are stateless.
• C. Firewall filters are stateful.
• D. Firewall filters can match Layer 4 parameters.

Correct answer: B, D

Explanation

The correct answers are B and D. Firewall filters are stateless, meaning they do not keep track of the state of connections, and they can match Layer 4 parameters, which include TCP and UDP ports. Options A and C are incorrect because they suggest capabilities that firewall filters do not possess; they do not match Layer 7 parameters and are not stateful.
