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? (Choose three.)

A.
encryption—scrambles the packet contents to prevent them from being seen by unauthorized
sources

B.
password—a password (community string) sent in clear text between a manager and agent for
added protection

C.
authentication—determines that the message is from a valid source

D.
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
