350-701 Practice Question: A network administrator needs to provide network…
A network administrator needs to provide network access to a legacy printer that does not support 802.1X. Which Cisco ISE feature should be used to authenticate this device?
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
✓
MAC Authentication Bypass
MAC Authentication Bypass (MAB) allows devices that cannot run 802.1X supplicant software to authenticate based on their MAC address. ISE can be configured to accept the MAC address as the credential.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Posture assessment
Why it's wrong here
Posture assessment checks security compliance but requires an 802.1X session first.
- ✗
Guest access with self-registration
Why it's wrong here
Guest access is for temporary users, not for non-supplicant devices like printers.
- ✗
Profiling using DHCP probe
Why it's wrong here
Profiling identifies device type but does not provide authentication; it complements MAB or 802.1X.
- ✓
MAC Authentication Bypass
Why this is correct
MAB uses the device's MAC address for authentication, suitable for non-802.1X devices.
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.
