Correct answer & explanation
✓
Default login authentication: local, line
The default method list for login authentication tries local first, then fallback to line password. The default for enable authentication uses enable password, then none. The default for PPP authentication uses local, then none. The default for command authorization uses local, then if-authenticated. The default for exec authorization uses local, then none.
Quick reference
AAA Protocol Comparison
| 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.

Same concept, more angles
1 more way this is tested on 350-401
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Drag and drop each AAA method list on the left to its correct fallback order on the right.
medium- ✓ P1.default login authentication: local case (no server defined): local
- ✓ P2.login authentication RADIUS-FIRST: RADIUS then local
- ✓ P3.login authentication TACACS-FIRST: TACACS+ then local
- ✓ P4.login authentication LOCAL-ONLY: local (no fallback)
- ✓ P5.login authentication NONE: none (no authentication required)
Why P1: Method lists define the order of authentication sources. The default login method uses local as fallback; a common RADIUS-first list uses local; a TACACS+-first list uses local; a local-only list uses no fallback; and a none list allows access without authentication.
