Which of the following statements about systemd-journald are true? (Choose three.)
Systemd-journald can indeed pass log messages to syslog for further processing, maintains metadata such as _UID or _PID for each message, and supports syslog facilities such as kern, user, and auth. This makes options C, D, and E the correct statements about systemd-journald.
