Question 760
At a manufacturing complex in Detroit, engineers report that a VoIP phone needs a limited bootstrap path before it can obtain a supported 802.1X configuration. The work affects production and maintenance endpoints. Which test result most directly confirms the required behavior?
Explanation
Correct Answer
This observation tests the MAC authentication fallback and headless devices requirement at a manufacturing complex in Detroit. The expected result is that headless endpoints receive only their authorized resource access and 802.1X-capable users still meet the stronger identity requirement. The necessary correction is to apply approved MAC authentication for devices without 802.1X while limiting the resulting role and keeping higher-assurance access for capable clients; a saved configuration alone would not prove it is working. In this case, the observed fault is that a VoIP phone needs a limited bootstrap path before it can obtain a supported 802.1X configuration.
Incorrect Answers
At a manufacturing complex in Detroit, this measures a different network requirement, RADIUS returned roles and downloadable policy. The case describes that a VoIP phone needs a limited bootstrap path before it can obtain a supported 802.1X configuration, so accepting this result would leave the primary fault without direct verification.
At a manufacturing complex in Detroit, this would verify Multi-domain port access, CoA and failure behavior, not the failure reported in this scenario. The requested closure criterion instead concerns MAC authentication fallback and headless devices: headless endpoints receive only their authorized resource access and 802.1X-capable users still meet the stronger identity requirement. In this case, the observed fault is that a VoIP phone needs a limited bootstrap path before it can obtain a supported 802.1X configuration.
At a manufacturing complex in Detroit, the observation may be useful for a separate Wired 802.1X supplicant and RADIUS flow test, but it does not establish that a VoIP phone needs a limited bootstrap path before it can obtain a supported 802.1X configuration has been resolved. The relevant check is the MAC authentication fallback and headless devices outcome.
