Question 250
At Technology Center, a handheld scans an AP yet fails to join after an advertised WLAN capability change. What safety boundary prevents the same campus failure in future deployments?
Explanation
Correct Answer
For Technology Center, the decisive mechanism is 802.11 association sequence. 802.11 discovery and association occur before user traffic can be successfully forwarded. Change WLAN capability requirements in a tested pilot rather than disabling security campus-wide is an enduring limitation on the operational risk, not simply a one-time passing test.
Incorrect Answers
This is relevant to PoE power negotiation, where 802.3af at and bt power classes and the switch budget constrain device operation In the Technology Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 802.11 discovery and association occur before user traffic can be successfully forwarded
This is relevant to LLDP topology and discovery, where lLDP supplies adjacent-device identity without proving end-to-end routing or authentication In the Technology Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 802.11 discovery and association occur before user traffic can be successfully forwarded
This is relevant to Ethernet negotiation and duplex, where 802.3 physical link negotiation precedes Layer 2 and Layer 3 service validation In the Technology Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 802.11 discovery and association occur before user traffic can be successfully forwarded
