An Administrator Sets Up a Network Scan Set in AirWave

An administrator sets up a network scan set in AirWave to scan a subnet to identify devices for a firmware upgrade. The scan completes and AirWave successfully uses the SNMP credentials to validate SNMP access.

A) Monitor the devices for needed firmware upgrades.
B) Define a scan credentials set for the devices.
C) Change the default credentials of the devices.
D) Manually upgrade the firmware of the devices.
