What cannot be discovered by Discovery technology?

The correct choice is that the network fabric and its relationships with consumers cannot be discovered by Discovery technology. ServiceNow Discovery is primarily designed to identify and map various devices and applications within an IT infrastructure. It can effectively discover components such as virtual machines in environments like VMware, network devices like routers and switches, and database servers.

However, the concept of a "network fabric" typically refers to a more abstract and holistic view of the network's architecture and the interconnected relationships between the various consumers of network services. While ServiceNow Discovery can identify individual devices, it may not fully capture the intricate relationships and operational context of a network fabric as a whole. This level of discovery often requires specialized tools or integrations that go beyond the standard Discovery capabilities, which is why it stands out as something that cannot be fully encompassed by Discovery technology.
