All of the above.

Explanation:
An internal polling agent of a device does not have to be an SNMP agent. This essentially means that your hardware and software systems do not have to support SNMP if you want to implement internal polling. All you need for hardware and software systems that do not support SNMP is an internal polling program that is capable of obtaining the status information produced by the internal agent of the device, and feeding it into an SNMP trap.
