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
✓
Check the TACACS Livelogs
Monitoring the TACACS Livelogs will show the live requests as they arrive at the ISE nodes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
View the Network Device list
Why it's wrong here
This only shows configured devices.
- ✓
Check the TACACS Livelogs
Why this is correct
Livelogs provide real-time visibility.
- ✗
Run a packet capture on the switch
Why it's wrong here
This is a troubleshooting step, but not the primary way to verify within ISE.
- ✗
Check the System Summary
Why it's wrong here
This shows overall health, not per-device traffic.
Quick reference
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.
