Question 990
During a planned campus-network change at an engineering school in Copenhagen, operators discover that a corridor looks fully covered on a heatmap but voice calls drop whenever users cross a stairwell. The design must preserve lab networks and WLAN testing. What evidence should the engineer request after the repair?
Explanation
Correct Answer
This observation tests the Wireless coverage versus capacity and roaming tuning requirement at an engineering school in Copenhagen. The expected result is that representative walking and busy-hour tests show good SNR, timely transitions and sustainable application service. The necessary correction is to balance AP placement and RF coverage with client density, roaming transition data and realistic application testing; a saved configuration alone would not prove it is working. In this case, the observed fault is that a corridor looks fully covered on a heatmap but voice calls drop whenever users cross a stairwell.
Incorrect Answers
At an engineering school in Copenhagen, this measures a different network requirement, Queue scheduling and congested egress. The case describes that a corridor looks fully covered on a heatmap but voice calls drop whenever users cross a stairwell, so accepting this result would leave the primary fault without direct verification.
At an engineering school in Copenhagen, this would verify QoS classification and DSCP trust boundaries, not the failure reported in this scenario. The requested closure criterion instead concerns Wireless coverage versus capacity and roaming tuning: representative walking and busy-hour tests show good SNR, timely transitions and sustainable application service.
At an engineering school in Copenhagen, the observation may be useful for a separate Wi-Fi airtime efficiency and data rates test, but it does not establish that a corridor looks fully covered on a heatmap but voice calls drop whenever users cross a stairwell has been resolved. The relevant check is the Wireless coverage versus capacity and roaming tuning outcome.
