An admin needs to find all log entries from the last hour that contain 'error' or 'failed' for a specific service. Which command is most efficient?

journalctl --since '1 hour ago' | grep service

journalctl -u service --since '1 hour ago' | grep -E 'error|failed'

grep -E 'error|failed' /var/log/syslog | grep service

A service is in a 'failed' state. The admin runs systemctl status and sees 'Active: failed'. The admin needs to determine if the failure is due to a configuration error or a missing dependency. Which approach is most effective?

Check systemctl list-dependencies service

Check the service's journal with journalctl -u service -p err and review the error messages

Review /var/log/messages for the service name
