350-701 Deploys Cisco ISE for network access control Practice Question
An organization deploys Cisco ISE for network access control. After successful 802.1X authentication, a user's device is found to be missing critical patches via posture assessment. The administrator wants to dynamically move the user to a remediation VLAN without requiring the user to reconnect. Which ISE capability enables this?
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)

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Change of Authorization (CoA)
Why this is correct
CoA enables ISE to update session authorization in real time, such as moving to a remediation VLAN.
- ✗
RADIUS Accounting
Why it's wrong here
RADIUS Accounting tracks session statistics but does not change authorization.
- ✗
MAB reauthentication
Why it's wrong here
MAB reauthentication would reauthenticate the device but does not dynamically change attributes without reconnection.
- ✗
Device Sensor profiling
Why it's wrong here
Device Sensor profiling collects device attributes but does not modify authorization.

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.
