CCNP Security Practice Question
Which TWO features are part of Cisco TrustSec for providing role-based access control?
⚠ Common exam trap
Cisco often tests the distinction between the authentication mechanism (802.1X) and the authorization/enforcement components (SGTs and SGACLs), leading candidates to mistakenly select 802.1X as a TrustSec RBAC feature.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Security Group Access Control Lists (SGACLs)
Security Group Access Control Lists (SGACLs) are a core component of Cisco TrustSec, enforcing role-based access control by applying policies based on Security Group Tags (SGTs). SGACLs replace traditional IP-based ACLs, allowing dynamic, identity-aware traffic filtering that scales across the network.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Security Group Access Control Lists (SGACLs)
Why this is correct
SGACLs enforce policies based on SGTs.
- ✗
Change of Authorization (CoA)
Why it's wrong here
CoA is used for mid-session policy changes, not a core TrustSec feature.
- ✗
802.1X authentication
Why it's wrong here
802.1X is an authentication protocol, not a TrustSec feature.
- ✓
Security Group Tags (SGTs)
Why this is correct
SGTs are used to classify traffic based on user/device identity.
- ✗
MACsec encryption
Why it's wrong here
MACsec provides encryption, not access control.
