What does SNMPv3 enhance compared to earlier versions?

1. Speed of data transfer

2. Message integrity and encryption

3. Device compatibility

4. User interface design

The correct answer is: Message integrity and encryption

SNMPv3 enhances message integrity and encryption compared to earlier versions of the Simple Network Management Protocol (SNMP). This version was developed to address significant security vulnerabilities that were present in its predecessors, SNMPv1 and SNMPv2c. With the introduction of SNMPv3, features such as authentication and encryption were established to ensure that the data being transmitted is secure and tamper-proof. Message integrity guarantees that the data sent between network devices has not been altered during transmission. Encryption protects sensitive information from being intercepted by unauthorized users. This level of security is essential in network management, particularly in environments where sensitive data or critical infrastructure needs protection from potential threats. In contrast, earlier versions did not inherently support these security features, which made them more susceptible to various attacks. While some of the other options may seem relevant, they do not directly reflect the core enhancements that SNMPv3 provides in terms of security and integrity.
