Which two statements about distributed automatic radio resource provisioning (DARRP) are correct?

DARRP performs continuous spectrum analysis to detect sources of interference. It uses this information to allow the AP to select the optimum channel.

DARRP performs measurements of the number of BSSIDs and their signal strength (RSSI). The controller then uses this information to select the optimum channel for the AP.

DARRP measurements can be scheduled to occur at specific times.

DARRP requires that wireless intrusion detection (WIDS) be enabled to detect neighboring devices.
