350-701 Practice Question: Wants to deploy Cisco ISE to authenticate devices…
An organization wants to deploy Cisco ISE to authenticate devices that do not support 802.1X supplicant software, such as printers and IoT sensors. Which authentication method should be configured on the switch port to allow these devices network access?
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
✓
MAB
MAC Authentication Bypass (MAB) allows devices that cannot run 802.1X supplicants to authenticate based on their MAC address. The switch sends the MAC address as the username and password to ISE.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
EAP-TLS
Why it's wrong here
EAP-TLS requires a client certificate, which non-supplicant devices typically do not have.
- ✓
MAB
Why this is correct
MAB uses the MAC address for authentication, ideal for devices without 802.1X support.
- ✗
EAP-FAST
Why it's wrong here
EAP-FAST requires supplicant support and is not typically used for non-supplicant devices.
- ✗
PEAP-MSCHAPv2
Why it's wrong here
PEAP-MSCHAPv2 requires credentials and supplicant interaction, not suitable for devices like printers.
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.
