CompTIA Linux+ XK0-006 (V8) Practice Question

A CentOS Stream 9 host is protected by firewalld. You have temporarily opened TCP port 8080 in the current ruleset to test a new micro-service. The test is successful, and you now need the rule to survive future reboots without replacing the active rules in the kernel (that is, you do not want to reload or restart firewalld). Which pair of commands satisfies these requirements?

  • firewall-cmd --add-port=8080/tcp --permanent

  • firewall-cmd --add-port=8080/tcp ; firewall-cmd --runtime-to-permanent

  • firewall-cmd --add-port=8080/tcp --permanent && firewall-cmd --reload

  • firewall-cmd --add-port=8080/tcp && systemctl restart firewalld
