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

Answer options

• A. "Discard" is the default action of packets that are not explicitly allowed.
• B. There can be only one firewall filter.
• C. There can be multiple firewall filters.
• D. "Accept" is the default action of packets that are not explicitly allowed.

Correct answer: A, C

Explanation

The statement in option A is correct because firewall filters typically discard any packets that are not explicitly allowed. Option C is also correct as multiple firewall filters can be implemented. Options B and D are incorrect because it is possible to have more than one firewall filter and the default action is not 'Accept'.
