350-701 Uses Cisco ISE for network access control Practice Question
An organization uses Cisco ISE for network access control. After a user authenticates via 802.1X, a posture assessment determines that the user's antivirus definitions are outdated. What ISE feature can be used to dynamically restrict the user's network access until the issue is resolved?
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
✓
Change of Authorization (CoA)
Change of Authorization (CoA) allows ISE to dynamically change the user's authorization state, such as moving them to a restricted VLAN or applying a more restrictive ACL, after posture assessment.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Profiling
Why it's wrong here
Profiling identifies device type, not for changing access post-authentication.
- ✓
Change of Authorization (CoA)
Why this is correct
CoA enables dynamic changes to VLAN or ACL after a session is established, based on posture or other conditions.
- ✗
TrustSec SGT assignment
Why it's wrong here
SGT assignment is part of TrustSec for security group tagging but does not dynamically change access based on posture.
- ✗
Guest portal
Why it's wrong here
Guest portal is for guest access, not for post-authentication policy changes.

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.
