Quick Answer
The answer is SXP, CTS manual configuration, and IP-to-SGT mapping via RADIUS. These three methods are valid because SXP (SGT Exchange Protocol) propagates SGTs between network devices, CTS manual configuration allows an administrator to statically assign an SGT to a port or host, and RADIUS-based authentication dynamically maps an IP address to an SGT during the authentication process. On the Cisco SCOR 350-701 exam, this question tests your understanding of how a switch actually obtains an SGT, distinguishing between direct assignment methods and broader data-sharing protocols. A common trap is confusing pxGrid—which ISE uses to share context, not for a switch to retrieve SGTs—with a valid method, or assuming VLAN-to-SGT mapping exists when SGTs are assigned per host, not per VLAN. Remember the mnemonic “SCR” for SXP, CTS manual, and RADIUS to recall the three valid methods.
This 350-701 practice question tests your understanding of secure network access, visibility and enforcement. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which THREE are valid methods to obtain security group tags (SGTs) on a Cisco switch? (Choose three.)
IP-to-SGT mapping via RADIUS
RADIUS can send SGT attributes during authentication.
CTS manual configuration
Administrators can statically assign SGTs on the switch.
Cisco ISE pxGrid subscription
Why wrong: pxGrid is used for contextual data sharing, not for obtaining SGTs on the switch.
VLAN-to-SGT mapping
Why wrong: VLAN is not directly mapped to SGT; SGT is assigned per endpoint.
SXP
SXP propagates SGT mappings between devices.
Answer choices
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, C, and D are correct. SXP (SGT Exchange Protocol) propagates SGTs, CTS manual configuration statically assigns SGTs, and IP-to-SGT mapping via RADIUS allows dynamic assignment. Option B is not a standard method (VLAN-to-SGT mapping is not directly supported; SGTs are per host). Option E (pxGrid subscription) is used by ISE to share data, not for the switch to obtain SGTs.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
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.
Related concept
Authentication checks who the user is.
CTS manual configuration
Why this is correct
Administrators can statically assign SGTs on the switch.

Authentication checks who the user is.
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.
Related concept
Authentication checks who the user is.
Common exam traps
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
A help-desk technician troubleshoots why a newly connected PC cannot reach shared printers on the same floor. The cable is good, the switch port is active, but the PC is in VLAN 20 and the printers are in VLAN 10. The uplink trunk only allows VLAN 10. A trunk being up does not mean every VLAN crosses it.
What to study next
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related 350-701 questions on access control and AAA configuration.
