Where do you start to achieve true network visibility?

The correct answer is D. Fabric Level. True network visibility begins at the fabric level, where the underlying network infrastructure provides comprehensive, pervasive insight into all traffic and connected entities.

Why each option

True network visibility begins at the fabric level, where the underlying network infrastructure provides comprehensive, pervasive insight into all traffic and connected entities.

AOT

OT (Operational Technology) is a specialized domain that benefits from network visibility but is not the foundational starting point for achieving true network-wide visibility.

BBranches

Branches are network segments that feed into the broader infrastructure; starting visibility efforts at the branch level yields only partial, siloed insight rather than true end-to-end coverage.

CIT

IT encompasses a broad set of systems and services, but true network visibility must begin at the fabric layer that underlies and interconnects all IT components, not at the application or service layer.

DFabric LevelCorrect

Starting at the fabric level means leveraging the network infrastructure itself - switches, routers, and fabric components - as distributed sensors that generate telemetry across the entire environment. This foundational layer provides the end-to-end context required before meaningful visibility can be extended to branches, IT systems, or OT domains, making it the correct starting point for comprehensive network awareness.
