350-701 Practice Question: A network administrator is deploying Cisco ISE…
A network administrator is deploying Cisco ISE for network access control. The network includes printers and IP phones that do not support 802.1X. Which TWO methods can be used to authenticate these devices?
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 (MAB)
MAB allows non-supplicant devices to be authenticated based on their MAC address. Profiling can identify the device type and apply appropriate policies. 802.1X requires a supplicant, and PEAP-MSCHAPv2 is a credential-based EAP method that also requires a supplicant.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
802.1X with EAP-TLS
Why it's wrong here
EAP-TLS requires certificate-based authentication and a supplicant.
- ✗
Posture assessment
Why it's wrong here
Posture assessment checks endpoint compliance after authentication, not for initial access.
- ✓
MAC Authentication Bypass (MAB)
Why this is correct
MAB bypasses 802.1X and authenticates based on MAC address.
- ✗
PEAP-MSCHAPv2
Why it's wrong here
PEAP-MSCHAPv2 is an 802.1X EAP method that requires a supplicant.
- ✓
Profiling
Why this is correct
Profiling uses probes to identify device type and can be used for authentication decisions.
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.
