A Linux administrator needs to ensure that a custom monitoring agent starts after the network is up and before the main application service on a systemd-based server. The agent is not required during emergency maintenance. Which approach best satisfies these requirements?

Add the agent startup command to /etc/rc.local and ensure the script runs at boot.

Create a systemd service unit with After=network-online.target and Before=app.service, then enable it.

Use a cron @reboot entry to start the agent after boot.

Place the agent binary in /etc/init.d/ and set the runlevel to 5.
