The correct answer is A: SNMPv3 enhanced SNMPv2 security features.. Three true statements are: (A) SNMPv3 enhanced SNMPv2 security features - SNMPv3 added message integrity, authentication (HMAC-MD5/SHA), and encryption (DES/AES) to address SNMPv2's reliance on plaintext community strings. (C) SNMPv2 added the Inform protocol message to SNMP - In

Question

Which three statements about the features of SNMPv2 and SNMPv3 are true? (Choose three.)

Options

ASNMPv3 enhanced SNMPv2 security features.
BSNMPv3 added the Inform protocol message to SNMP.
CSNMPv2 added the Inform protocol message to SNMP.
DSNMPv3 added the GetBulk protocol messages to SNMP.
ESNMPv2 added the GetBulk protocol message to SNMP.
FSNMPv2 added the GetNext protocol message to SNMP.

Explanation

Three true statements are: (A) SNMPv3 enhanced SNMPv2 security features - SNMPv3 added message integrity, authentication (HMAC-MD5/SHA), and encryption (DES/AES) to address SNMPv2's reliance on plaintext community strings. (C) SNMPv2 added the Inform protocol message to SNMP - Inform was introduced in SNMPv2 as a reliable, acknowledged alternative to traps; SNMPv3 inherited it. (E) SNMPv2 added the GetBulk protocol message to SNMP - GetBulk was introduced in SNMPv2 to efficiently retrieve large blocks of MIB data in a single request. The false statements: B and D are wrong because Inform and GetBulk were SNMPv2 additions, not SNMPv3. F is wrong because GetNext was part of SNMPv1, not a new feature of SNMPv2.
