SISE Network Access Device Administration Practice Question
You need to ensure that TACACS+ authentication requests for network devices are only accepted if the device IP matches a specific Network Device Group. Where do you configure the Device Type condition?
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
✓
In the Policy Set condition using 'Device Type'
Policy sets allow for conditions based on Network Device Groups (NDG), which are mapped to devices.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
In the Command Set definition
Why it's wrong here
Command sets define command permissions, not device scoping.
- ✗
In the TACACS+ Profile settings
Why it's wrong here
Profiles define authorization attributes, not device matching.
- ✓
In the Policy Set condition using 'Device Type'
Why this is correct
Conditions based on NDG (Device Type) are evaluated at the policy set or policy rule level.
- ✗
In the Global System Settings
Why it's wrong here
Global settings do not support granular policy-based device matching.
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.
