Question 112
Which of the following statements about sytemd-journald are true? (Choose three.)
Correct Answer: C,D,E
systemd-journald is a system service that collects and stores logging data from various sources, such as kernel, user-mode programs, and services1. It creates and maintains structured, indexed journals that include metadata and binary data where necessary1. The journal format is secure and unfakeable1. systemd-journald is not incompatible with syslog and can coexist with it. It can forward log messages to a syslog daemon for further processing, filtering, or storage2. This can be enabled by setting the ForwardToSyslog option to yes in the /etc/systemd/journald.conf file2. systemd-journalddoes not only process messages of systemd, but also messages of any other tools that use the standard logging interfaces, such as syslog(3), sd_journal_print(3), or systemd-cat(1)1. systemd-journald also supports syslog facilities, such as kern, user, and auth, which are used to specify the type of program that is logging the message3. These facilities can be used to filter the journal entries by using the -p or --priority option of the journalctl command4. For example, to show only kernel messages, we can use journalctl -p kern4.
