Question 380
During a planned campus-network change at a public library in Portland, operators discover that two neighboring APs at maximum power create the same-channel contention that wide channels cannot resolve. The design must preserve staff and visitor wireless access. Which post-change observation is the strongest acceptance evidence?
Explanation
Correct Answer
This observation tests the Channel width, DFS and co-channel interference requirement at a public library in Portland. The expected result is that the WLAN has fewer overlapping competing cells, DFS events are accounted for, and representative traffic meets channel-use targets. The necessary correction is to tune channel width and eligible channels using measured channel utilization, DFS requirements and neighboring AP overlap; a saved configuration alone would not prove it is working. In this case, the observed fault is that two neighboring APs at maximum power create the same-channel contention that wide channels cannot resolve.
Incorrect Answers
At a public library in Portland, the observation may be useful for a separate AirMatch RF power and channel optimization test, but it does not establish that two neighboring APs at maximum power create the same-channel contention that wide channels cannot resolve has been resolved. The relevant check is the Channel width, DFS and co-channel interference outcome.
At a public library in Portland, this would verify AP uplink and client address dependencies, not the failure reported in this scenario. The requested closure criterion instead concerns Channel width, DFS and co-channel interference: the WLAN has fewer overlapping competing cells, DFS events are accounted for, and representative traffic meets channel-use targets.
At a public library in Portland, the observation may be useful for a separate Wireless guest policy and isolation test, but it does not establish that two neighboring APs at maximum power create the same-channel contention that wide channels cannot resolve has been resolved. The relevant check is the Channel width, DFS and co-channel interference outcome.
