Exam JN0-104 topic 1 question 78 discussion

A and D are correct - remove the "15" at the end of D

A and D are the right answer

The correct statements about firewall filters are: A. Firewall filters provide stateless security. D. Firewall filters are applied to interfaces. Firewall filters are used to apply security rules to network traffic based on specific criteria, such as source/destination addresses, protocols, ports, etc. They provide stateless security, meaning each packet is evaluated individually without considering the context of previous packets. Firewall filters are typically applied directly to interfaces to control the traffic flowing through them. They can be applied to both ingress (incoming) and egress (outgoing) traffic on an interface. They can be used to filter traffic before it reaches the security policies, which are higher-level constructs used for policy enforcement.

AD is correct. Firewall filter should be applied to interfaces

I believe it is a typo, the original sentence should be - "Firewall filters are applied to interfaces." So the answers are correct.

What does this mean: Firewall filters are applied to interfaces 15. why the 15?
