Which two SNMPv2 features allow retrieving large datasets in one request and acknowledging traps? (Choose two.)

GetBulk and Inform are key features introduced in SNMPv2. GetBulk allows a Network Management System (NMS) to retrieve large amounts of data from an SNMP agent with a single request, significantly reducing network overhead compared to multiple GetNext requests. Inform messages enable an SNMP manager to send acknowledged traps to another SNMP manager, ensuring reliable delivery of critical event notifications. Get and GetNext are fundamental SNMP operations for retrieving individual or sequential MIB object values, but they are not designed for large dataset retrieval in a single request like GetBulk. Set is used for modifying MIB object values, not for data retrieval or acknowledged traps.
