Which file extension is required when deploying Cisco ISE using a ZTP configuration file in Microsoft Hyper-V?

A .txt file is a plain text file and cannot be directly used as a ZTP configuration file for Cisco ISE on Hyper-V; it must be part of an ISO.

An .img file is typically a disk image and is not the required file type for embedding a ZTP configuration file for Cisco ISE on Hyper-V.

A .tar file is an archive format and is not the required file type for embedding a ZTP configuration file for Cisco ISE deployment on Hyper-V.

For Cisco ISE Zero Touch Provisioning (ZTP) in a Hyper-V environment, the ZTP configuration file needs to be part of an ISO image. The Hyper-V virtual machine is then configured to boot from this ISO, allowing the ISE installer to automatically retrieve and apply the configuration during setup.
