Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
In the Policy Set Authentication rule
Why it's wrong here
Authentication rules only handle login verification.
- ✗
In the Authorization Profile
Why it's wrong here
Authorization Profiles are for RADIUS, not TACACS+ command sets.
- ✓
In the Command Set Policy Element
Why this is correct
Command Sets are where specific CLI commands are permitted or denied.
- ✗
In the User Identity Group
Why it's wrong here
Groups organize users but do not define command permissions.
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.
