Which two of the following requirements must be met to detect duplex mismatches?

Comprehensive and Detailed Explanation From Exact Extract:

To detect duplex mismatches:

The node must be monitored (i.e., managed in SolarWinds).

The node must be in "up" status, so SNMP data about interface status, speed, and errors can be polled and compared.

Description in MIB (A) is not necessary if the device is already SNMP-capable, and "warning" status (C) is a result, not a requirement.
