Which SNMP message is used by a manager to modify or assign values to the agents?

SNMP GET
SNMP SET
SNMP GET-NEXT
SNMP TRAP

The correct answer is: SNMP SET

The SNMP SET message is utilized by a manager to modify or assign values to the agents. This command allows the network management system to change configuration settings or operational parameters on devices being monitored. When a manager sends an SNMP SET request, it specifies the object identifiers (OIDs) for the data it wishes to modify along with the new values for those data points. In the context of network management, the ability to change settings via SNMP SET commands is vital for maintaining and optimizing the performance of network devices. It allows administrators to remotely manage configurations and adapt device settings as necessary without requiring physical access to the hardware. The other types of SNMP messages have different functions: SNMP GET is used to retrieve values from the agents without changing them, SNMP GET-NEXT allows the manager to iterate through a collection of OIDs, and SNMP TRAP provides a way for agents to inform the manager of significant events or changes, rather than the manager initiating changes.
