Which two messages does SNMP version 2 add to the existing message types?

Acknowledgment and Confirmation
INFORM and GETBULK
Checkpoint and Report
START and STOP

The correct answer is: INFORM and GETBULK

SNMP version 2 introduced new message types to enhance the protocol's capabilities. Among these, the INFORM message allows for the sending of notifications that require acknowledgment from the receiving party. This feature offers enhanced reliability since the sender can be informed when the message is received, which is particularly useful in network management scenarios. The GETBULK message is another significant addition that facilitates the retrieval of large amounts of data in a more efficient manner than its predecessor. This is especially advantageous when dealing with devices that contain a lot of information, as it reduces the number of requests needed to gather large data sets. Both of these messages together help to improve the functionality and efficiency of SNMP, making it more suitable for managing larger and more complex networks. This advancement over SNMP version 1 indicates a significant step forward in network management capabilities. Other options listed do not correspond to message types introduced in SNMP version 2.
