Refer to the exhibit. A network administrator wants to enhance the security for SNMP for this configuration. Which action can the network administrator implement?

While SNMPv2 with MD5 authentication provides message integrity and authentication, it does not offer encryption (privacy) for the SNMP data itself, making it less secure than SNMPv3.

Adding a community string to an existing entry is part of the basic configuration for SNMPv1/v2c and does not enhance security beyond what these versions inherently provide, which is sending community strings in clear text or with minimal security.

SNMPv3 offers significant security enhancements over SNMPv1 and SNMPv2c by providing message integrity, authentication, and encryption (privacy). It uses usernames with authentication protocols (like MD5 or SHA) and encryption protocols (like DES or AES) to secure SNMP communications, making it the most secure option for SNMP management.

Switching to an encrypted password for device access through SSH enhances the security of management access to the device but does not improve the security of SNMP communication itself.
