Question 1050
At Research Hub, a wired label printer has no 802.1X supplicant and remains blocked on an authenticated access port. Which check provides the most useful information for fixing this deployment?
Explanation
Correct Answer
For Research Hub, the decisive mechanism is MAB for headless IoT. MAB is a weaker fallback identity mechanism than certificate-based 802.1X. Inspect MAB attempt matched endpoint identity and ClearPass policy is the most direct way to isolate this particular failure before making a change.
Incorrect Answers
This is relevant to Supplicant reauthentication intervals, where wired reauthentication intervals can affect session continuity if handshake timing is inadequate In the Research Hub case, Those observations could be normal while the stated fault persists. The specific mechanism is mAB is a weaker fallback identity mechanism than certificate-based 802.1X
This is relevant to Dynamic VLAN on wired port, where dynamic VLAN assignment requires compatible RADIUS results and local switch VLAN support In the Research Hub case, Those observations could be normal while the stated fault persists. The specific mechanism is mAB is a weaker fallback identity mechanism than certificate-based 802.1X
This is relevant to TACACS+ admin AAA distinction, where administrative command authorization and client-port 802.1X solve different AAA problems In the Research Hub case, Those observations could be normal while the stated fault persists. The specific mechanism is mAB is a weaker fallback identity mechanism than certificate-based 802.1X
