What kind of information is essential for the setup wizard in Tenable.sc?

The setup wizard in Tenable.sc requires network infrastructure information as it is crucial for configuring the system to effectively scan and manage the network environment. This information allows Tenable.sc to understand the layout and structure of the network, including IP ranges, subnets, and connected devices. By accurately capturing this data, the setup wizard ensures that the deployment aligns with the existing network architecture, enabling efficient vulnerability assessments and security management.

In the context of the other options, while data from past installations, system resource usage reports, and configuration data from Nessus may be useful for various administrative tasks or troubleshooting, they are not foundational elements needed during the initial setup process. The primary goal of the setup wizard is to establish a clear understanding of the network it will be monitoring.
