A branch office has to carry RADIUS traffic to a data center over a shared circuit and the security team wants the transport itself protected rather than a separate tunnel built around it. The team turns on RADIUS over TLS at both ends. Which statement describes how the two ends now exchange traffic?

- Two UDP ports stay in use for authentication and accounting traffic while a third port carries the dynamic authorization traffic and the shared secrets stay separate
- A single TCP port carries all three kinds of traffic and the shared secret is dropped because the transport already proves who each end is
- A single UDP port carries all three kinds of traffic and the shared secret is agreed inside the handshake before any RADIUS packet is sent at all
- A single TCP port carries all of authentication and accounting and dynamic authorization and the shared secret left for the older integrity checks becomes a fixed word
