This 350-701 practice question tests your understanding of secure network access, visibility and enforcement. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
In a Cisco TrustSec deployment, you want to dynamically assign SGTs based on user authentication. Which mechanism should you use?
CTS SXP
Why wrong: SXP is used to propagate SGT mappings, not to assign them dynamically.
CTS RBACL
Why wrong: RBACLs enforce policies based on roles, not dynamically assign SGTs.
CTS device classification
Why wrong: Device classification assigns SGTs based on static criteria.
CTS identity-based networking (IBNS) with RADIUS CoA
IBNS with CoA can dynamically assign SGTs via RADIUS attributes.
Answer choices
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
Option D is correct. Identity-Based Networking Services (IBNS) with RADIUS Change of Authorization (CoA) allows dynamic assignment of SGTs during authentication. Option A (RBACL) is for role-based access control, not SGT assignment. Option B (SXP) propagates SGTs but doesn't assign dynamically. Option C (device classification) is for static assignment.
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.
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.
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 security administrator must allow nursing staff to reach a patient records server while blocking access from the guest Wi-Fi VLAN. After applying an extended ACL, traffic is still blocked from nursing workstations. The ACL was applied outbound instead of inbound on the wrong interface. Questions like this test ACL direction and placement rules.
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.
