Does SNMP v. 3 introduce any new message types?

  1. No

  2. Yes, it introduces two new types

  3. Yes, but only for security enhancements

  4. No, it only enhances existing types

The correct answer is: No

The correct answer indicates that SNMPv3 does not introduce any new message types compared to its predecessors. Instead, it enhances existing functionalities and focuses on improving security and administration of the protocol. SNMPv3 retains the same message types that were available in SNMPv1 and SNMPv2, which include GetRequest, GetNextRequest, SetRequest, GetResponse, and Trap. The enhancements in SNMPv3 primarily revolve around security features, including authentication, encryption, and role-based access control. Therefore, while the capabilities of SNMP have been significantly improved, the fundamental set of message types has remained unchanged. This focus on security and access control is what distinguishes SNMPv3, rather than the introduction of new message types.
