Correct answer & explanation
pxGrid: Enables real-time context sharing between DNA Center and ISE
ISE integration: pxGrid shares context data; TrustSec enforces segmentation; RADIUS provides authentication; SGT carries security group tags.
Quick reference
| Protocol | Port(s) | Encryption | Transport | Primary Use |
|---|---|---|---|---|
| RADIUS | 1812 / 1813 | Password only | UDP | Network access control |
| TACACS+ | 49 | Full packet | TCP | Device administration |
| Diameter | 3868 | Full session | TCP / SCTP | Carrier / mobile networks |
| 802.1X | — | EAP-based | Layer 2 | Port-based access control |
TACACS+ encrypts the entire packet; RADIUS only encrypts the password field — a key exam distinction.
