Cisco NX-OS Software supports SNMPv1， SNMPv2c， and SNMPv3. Both SNMPv1 and SNMPv2c use a community-based form of security. SNMPv3 provides secure access to devices by a combination of authenticating and encrypting frames over the network. Which security features are provided in Cisco NX-OS SNMPv3？ （）A、 encryption—scrambles the packet contents to prevent them from being seen by unauthorized sourcesB、 password—a password （community string） sent in clear text between a manager and agent for added protectionC、 authentication—determines that the message is from a valid sourceD、 message integrity—ensures that a packet has not been tampered with while it was in transit E、 user—to determine if user authentication is used instead of community strings
