Which option names a firewall component associated with OpenBSD Packet Filter?

• A. PF: OpenBSD Packet Filter
• B. Netfilter
• C. Stunnel
• D. NMAP

Answer: (A)

OpenBSD's firewall component is PF, short for Packet Filter. This built-in firewall system filters traffic, supports NAT, and is configured with pf.conf. The option that names PF as OpenBSD Packet Filter is correct because it directly identifies OpenBSD’s firewall component. Netfilter is the Linux firewall framework, Stunnel is a TLS wrapper, and NMAP is a network scanner, none of which are part of OpenBSD Packet Filter.
