350-701 Practice Question: Secure Network Access, Visibility and Enforcement
Which THREE are valid methods to obtain security group tags (SGTs) on a Cisco switch? (Choose three.)
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
✓
IP-to-SGT mapping via RADIUS
Options A, B, and E are correct. IP-to-SGT mapping via RADIUS (A) dynamically assigns SGTs based on authentication results. CTS manual configuration (B) allows static SGT assignment per interface or port. SXP (E) propagates SGTs between devices. Option C (Cisco ISE pxGrid subscription) is used for data sharing, not for a switch to obtain SGTs. Option D (VLAN-to-SGT mapping) is not a standard method; SGTs are assigned per host, not per VLAN.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
IP-to-SGT mapping via RADIUS
Why this is correct
RADIUS can send SGT attributes during authentication.
- ✓
CTS manual configuration
Why this is correct
Administrators can statically assign SGTs on the switch.
- ✗
Cisco ISE pxGrid subscription
Why it's wrong here
pxGrid is used for contextual data sharing, not for obtaining SGTs on the switch.
- ✗
VLAN-to-SGT mapping
Why it's wrong here
VLAN is not directly mapped to SGT; SGT is assigned per endpoint.
- ✓
SXP
Why this is correct
SXP propagates SGT mappings between devices.

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.
