DNA Center provides intent-based policy orchestration while Cisco ISE supplies identity and posture enforcement; integrating the two lets policies adapt to user and device context. Mobile-device-management (MDM) connectors in ISE supply detailed posture attributes. Cisco Spaces ingests AP telemetry from Catalyst 9800/9100 to deliver real-time and historical location analytics. Combining these three platforms gives dynamic identity/posture-aware network access plus granular visibility into device activity and location.

B. Lacks ISE and Spaces, so no identity, posture, or location visibility.

C. Static VLAN assignments ignore identity‐based policy and device posture; Spaces is absent.

D. Omits MDM and Spaces, so no posture assessment and no location analytics.
