Which feature supported by SNMPv3 provides an advantage over SNMPv2c?

• A. Transport mapping
• B. Community strings
• C. GetBulk
• D. Encryption

Answer: (D)

Encryption is the feature that SNMPv3 brings to the table to protect management data in transit. It provides privacy by encrypting the SNMP payload, so someone sniffing the network can’t read the values, credentials, or sensitive information. SNMPv2c relies on community strings for authentication and does not encrypt traffic, leaving data exposed. Other options aren’t security enhancements unique to SNMPv3: GetBulk is just a way to retrieve multiple items and is available in older versions; transport mapping is about how messages are carried and isn’t a security feature by itself; community strings are the old, insecure authentication method used in earlier versions. So encryption directly delivers confidentiality, making it the best advantage of SNMPv3 over SNMPv2c.
