Exam 300-715 topic 1 question 282 discussion

When deploying Cisco ISE using a ZTP configuration file in Microsoft Hyper-V, the file extension used is .iso. This is because Hyper-V does not support the standard ".img" file format used for ZTP on other platforms, requiring the use of an ISO image instead.

The ZTP configuration file must be provided via a bootable medium that Hyper‑V can mount as a virtual CD/DVD drive. In Hyper-V, that medium is an ISO image. Even though the actual ZTP configuration content is typically stored in a text file (often named something like ztp.txt), the file must be packaged into an ISO image for Hyper‑V to recognize and attach it during the boot process

When deploying Cisco Identity Services Engine (ISE) using Zero-Touch Provisioning (ZTP) in Microsoft Hyper-V, the configuration file must have a .txt extension. This text file contains the necessary bootstrapping configurations for automating the deployment of Cisco ISE. iso file is needed if you want to deploy Cisco ISE without ztp
