350-701 Practice Question: Secure Network Access, Visibility and Enforcement
In a Cisco TrustSec deployment, you want to dynamically assign SGTs based on user authentication. Which mechanism should you use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
CTS identity-based networking (IBNS) with RADIUS CoA
Identity-Based Networking Services (IBNS) with RADIUS Change of Authorization (CoA) allows dynamic assignment of SGTs during authentication. Option A (CTS SXP) propagates SGTs but doesn't assign dynamically. Option B (CTS RBACL) is for role-based access control, not SGT assignment. Option C (CTS device classification) is for static assignment.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
CTS SXP
Why it's wrong here
SXP is used to propagate SGT mappings, not to assign them dynamically.
- ✗
CTS RBACL
Why it's wrong here
RBACLs enforce policies based on roles, not dynamically assign SGTs.
- ✗
CTS device classification
Why it's wrong here
Device classification assigns SGTs based on static criteria.
- ✓
CTS identity-based networking (IBNS) with RADIUS CoA
Why this is correct
IBNS with CoA can dynamically assign SGTs via RADIUS attributes.
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.
