Exam SY0-601 topic 1 question 533 discussion

C. Configure SNMPv3. In this scenario, the security analyst discovered a network device with cleartext authentication and a default credential. To secure the device, the best recommendation is to configure SNMPv3. SNMP (Simple Network Management Protocol) is commonly used for network monitoring and management. SNMPv1 and SNMPv2c use cleartext authentication, which means that the credentials are transmitted without encryption, making them vulnerable to eavesdropping and potential credential theft. SNMPv3 is the most secure version of SNMP and provides several security features, including data encryption, message integrity, and authentication. It uses technologies such as HMAC (Hash-based Message Authentication Code) and encryption algorithms to protect sensitive information, making it the preferred choice when securing network devices and preventing unauthorized access or misuse.

Similar question from Darril Gibson's book Chapter 3 practice questions, but the answer there is SSH. However he provides the answer still for this question as below. "9. Network administrators manage network devices remotely. However, a recent security audit discovered they are using a protocol that allows them to send credentials over the network in cleartext. Which of the following methods should be adopted to eliminate this vulnerability? The scenario indicates that administrators are likely using Simple Network Management Protocol v1 (SNMPv1), SNMPv2, or SNMPv2c. These protocols all send a community string over the network in cleartext. SNMPv3 encrypts the credentials before sending them over the network."

Going with SNMPv3, is the most secure. Answer D makes no sense

What a strange set of answers, but just going with the most secure answer
