Quiz: what a server exposes

One correct answer

You wrote the ruleset to /etc/nftables.conf and loaded it with sudo nft -f /etc/nftables.conf. The nftables service is disabled. What happens to the filter after a reboot?

• A The ruleset will be empty — nobody reads the file at boot.
• B The ruleset loads — nft -f enables the service by itself.
• C The ruleset stays — the kernel keeps rules between boots.
