A server's firewall is managed by firewalld. The admin adds a rule to allow HTTPS traffic to the public zone, but clients still cannot connect. What is the most likely cause?
2After configuring sudo, a user reports: 'sudo: unable to open /etc/sudoers: Permission denied'. The admin checks the file permissions and sees '-rw-r-----' owned by root:root. What is the most likely cause?
3A server uses firewalld with the default zone set to 'drop'. SSH is allowed only for the 192.168.1.0/24 subnet via a rich rule in the 'internal' zone. After a reboot, SSH connections from that subnet are refused. What is the most likely cause?
4Which command sets the password maximum age for user 'bob' to 30 days?
5A file has been assigned an incorrect SELinux context, preventing a service from accessing it. Which command restores the default SELinux context for that file?
6A systems administrator needs to list all currently defined firewall rules in firewalld, including rules for all zones. Which TWO commands can be used to accomplish this? (Choose exactly two.)
