Which three statements about the features of SNMPv2 and SNMPv3 are true? (Choose three.)
Click on the arrows to vote for the correct answerA. B. C. D. E. F.
SNMP (Simple Network Management Protocol) is an application layer protocol used to manage and monitor network devices. SNMP has gone through several versions, with the most widely used being SNMPv2 and SNMPv3.
The three statements about the features of SNMPv2 and SNMPv3 that are true are:
A. SNMPv3 enhanced SNMPv2 security features SNMPv3 added several security features that were not present in SNMPv2. These include message integrity, authentication, and encryption. SNMPv3 also introduced the use of User-based Security Model (USM) to provide secure access control.
B. SNMPv3 added the Inform protocol message to SNMP. The Inform protocol message is used by SNMP managers to notify other managers of changes in the network. SNMPv3 added this protocol message to the SNMP protocol.
E. SNMPv2 added the GetBulk protocol message to SNMP. The GetBulk protocol message was introduced in SNMPv2 to reduce the number of protocol exchanges needed to retrieve a large amount of data. With the GetBulk message, multiple values can be retrieved in a single exchange.
Therefore, options A, B, and E are the correct answers.
Option C is incorrect because the Inform protocol message was added to SNMP in SNMPv3 and not in SNMPv2.
Option D is also incorrect because the GetBulk protocol message was introduced in SNMPv2 and not in SNMPv3.
Option F is incorrect because the GetNext protocol message was added in SNMPv1 and not in SNMPv2.
