You want to view all messages in the journal related to the Linux fi rewall. Which of the following commands could you use to view the fi rewall information? journalctl fi rewalld journalctl -b fi rewalld journalctl -f fi rewalld journalctl -u fi rewalld Explanation The journalctl -u fi rewalld command would display all messages in the journal related to the Linux fi rewall. The -u option displays only log entries related to a speci fi c service running on the system. The journalctrl command by itself displays the contents of the entire journal, starting with the oldest entries. Adding fi rewalld to the command would return an error message. The journalctrl -f command displays the last few entries in the journal and then prints new entries as they are added. There is no option for viewing only information related to a speci fi c daemon (such as fi rewalld ). The journalctrl -b command displays messages from the most recent system boot. You can add a number to display messages from a speci fi c boot (such as journalctrl -b 2 ), but there is no option for fi ltering by a speci fi c daemon.

Which of the following daemons is used on newer system-based distributions to provide a local system log fi le? journald syslog systemctl rsyslog Explanation Newer Linux distributions do not use SysVinit (init) and syslogd anymore. Instead, they use the journald daemon to provide a local system log fi le. Older init-based Linux distributions use the syslog daemon to manage system logging. rsyslog is a lightweight daemon that provides centralized logs. systemctl manages network services on systemd-based distributions. (journalctl is used to view the entire journal on a system running journald.) References  1.1.4 Server Roles Facts 
