Which device information is required on PNP/ZTP to support the zero touch onboarding process?
The correct answer is A. serial and chassis numbers. For zero-touch onboarding via Plug and Play (PNP) or Zero Touch Provisioning (ZTP), the device's unique serial number and chassis number are essential for identification and authentication.

Why each option
For zero-touch onboarding via Plug and Play (PNP) or Zero Touch Provisioning (ZTP), the device's unique serial number and chassis number are essential for identification and authentication.
The serial number and chassis number uniquely identify a device in the network infrastructure and are critical for the ZTP or PNP process to match the physical device with its pre-configured entry in the controller, enabling automated configuration and onboarding. This information is typically pre-loaded into the ZTP server or controller to validate the device requesting to join the overlay network.
An interface IP address is assigned during the onboarding process, not required for initial device identification by PNP/ZTP.
A public DNS entry is not a piece of device information required for the initial identification and onboarding process itself.
The system IP address is assigned or learned during the onboarding process, not a prerequisite for ZTP/PNP identification.
