Concept

Grouping data by the part of the estate it comes from is what makes a dashboard readable. The network domain is about the path traffic takes rather than about what happens at either end.

Why B

Splunk documents the Network Protection domain as covering the network and network-based devices, including routers, switches, firewalls and IDS devices.

Source

The Network Protection domain provides insight into the network and network-based devices, including routers, switches, firewalls, and IDS devices.
