An administrator wants to be alerted when the 'sshd' service stops running. They want to use a simple, built-in method that does not require a third-party monitoring tool. What is the most appropriate way to achieve this?

Monitor the /var/log/secure log file

Use the watch command to monitor the process

Configure a systemd service to restart sshd automatically

Create a cron job that checks the service status and sends an email if it is not active

An administrator needs to be notified when the disk usage on the root filesystem exceeds 90%. The administrator wants a simple, built-in solution that does not require installing additional packages. What should the administrator configure?

An entry in /etc/fstab to remount the filesystem read-only

A systemd timer that runs journalctl and triggers a service

A cron job that runs df -h and sends an email if usage is above 90%

A logrotate configuration to compress old logs
