An administrator is creating a new Content Library. It will subscribe to another remote Content Library without authentication enabled. What information from the published library will they need in or

The Subscription URL uniquely identifies the remote published library endpoint and is the only mandatory field vCenter requires when creating a subscribed Content Library without authentication. vCenter uses this URL to discover and download the library's Items.json metadata and sync content automatically.

A security password is only prompted when the publishing library has authentication enabled; the scenario explicitly states authentication is not enabled, so no password is required or accepted.

The Items.json file is an internally generated metadata manifest that vCenter retrieves automatically from the publishing library via the Subscription URL; administrators do not manually obtain or supply this file during subscription setup.

A username credential is only required when the publishing library enforces authentication; because authentication is disabled on the publishing library in this scenario, no username needs to be provided.
