Which two features introduced in SNMPv2 provide the ability to retrieve large amounts of data...

Answer D,E is correct: D. GetBulk; E. Inform. SNMPv2 added operational improvements beyond basic SNMPv1 polling. GetBulk allows a manager to retrieve large blocks of management data efficiently, reducing repeated GetNext operations when walking tables. Inform messages are also associated with SNMPv2 and provide acknowledged notifications between SNMP entities. Basic Get and Set operations are not the distinguishing SNMPv2 features in this option set. Cisco CCNA 200-301 v1.1 IP Services expects engineers to recognize how SNMP versions differ: SNMPv1 and v2c use community-based access, SNMPv2 adds GetBulk and Inform, and SNMPv3 adds authentication and encryption. The corrected answer pair is GetBulk and Inform, with GetBulk being the feature directly tied to large data retrieval.
