A network administrator is deploying SNMPv3 across a network. The administrator needs to configure authentication and encryption for SNMP traffic. However, some legacy devices only support SNMPv2c. The administrator must ensure that all devices are monitored securely. Which approach best meets the requirement?

Use SNMPv3 with authNoPriv on all devices.

Configure SNMPv3 on devices that support it and use SNMPv2c with strong community strings on legacy devices.

Replace all legacy devices with new ones that support SNMPv3.

Use SNMPv2c on all devices with complex community strings.

Why are community strings considered a security risk in SNMPv1/v2c?

They are sent in plaintext and can be intercepted.

They are only supported on UDP port 161.

They are too short to be secure.

They are automatically shared with all devices on the network.
