Claire is concerned about an attacker getting information regarding network devices and their configuration in her company. Which protocol should she implement that would be most helpful in mitigating this risk while providing management and reporting about network devices?

If Claire is using Simple Network Management Protocol (SNMP) to manage and monitor her network devices, she should make sure she is using SNMPv3 and that it is properly configured. SNMPv3 can provide information about the status and configuration of her network devices. Remote Authentication Dial-In User Service (RADIUS) might be used to authenticate to the network, but Transport Layer Security (TLS) and SSH File Transfer Protocol (SFTP) are not specifically used for the purposes described.
