What must be enabled in a scan to allow assets that are turned off to be powered on?

To enable assets that are turned off to be powered on during a scan, the Wake On LAN configuration must be utilized. This feature allows the scanning tool to send a special packet known as a "magic packet" over the network to a powered-off device, prompting it to power on. This functionality is crucial in environments where asset tracking and vulnerability assessment need to include devices that are not always powered on.

When Wake On LAN is correctly configured, it enables the scanning system to increase its coverage and ensure comprehensive data collection. The configuration requires that the target devices support Wake On LAN, which typically necessitates specific settings in both the BIOS/UEFI firmware and the network interface card.

Regarding the other choices, Host Discovery settings handle identification of active hosts on the network, while the Network Scanning feature pertains to how the scanner interacts with the network itself. Custom Scan Policy options allow for specific adjustments to scan parameters but do not inherently include the capability to wake devices.
