What is a characteristic of a ZTP Day 0 provisioning method?

Zero Touch Provisioning (ZTP) is inherently designed for high scalability. It automates the initial configuration and onboarding of numerous network devices, enabling large-scale deployments without requiring human intervention for each device, significantly speeding up network expansion and setup.

Enabling Guest Shell is a specific feature of some Cisco IOS XE devices for running Linux applications, but it is not a defining characteristic or a primary goal of the ZTP provisioning method itself.

Enabling an Admin Shell, like Guest Shell, is a specific feature or configuration option, not a universal characteristic of ZTP's core functionality, which focuses on automated initial setup.

While ZTP aims to be secure, security is usually implemented within the ZTP process (e.g., using secure boot, signed images, authentication), but "highly secure" is not its defining characteristic compared to its core purpose of automation and scalability.
