Question 350
At a design studio in Berlin, engineers report that an engineer disables the only band supported by a group of legacy barcode devices. The work affects wireless workstations and video conferences. Which post-change observation is the strongest acceptance evidence?
Explanation
Correct Answer
This observation tests the Wireless radio bands and channel availability requirement at a design studio in Berlin. The expected result is that only supported clients associate on the authorized band and the RF plan uses permitted channels with acceptable signal and coverage. The necessary correction is to select appropriate 2.4, 5 or 6 GHz radio and compatible channels based on client capability, regulatory domain and coverage requirement; a saved configuration alone would not prove it is working. In this case, the observed fault is that an engineer disables the only band supported by a group of legacy barcode devices.
Incorrect Answers
At a design studio in Berlin, the observation may be useful for a separate AP uplink and client address dependencies test, but it does not establish that an engineer disables the only band supported by a group of legacy barcode devices has been resolved. The relevant check is the Wireless radio bands and channel availability outcome.
At a design studio in Berlin, this measures a different network requirement, Client steering and roaming design. The case describes that an engineer disables the only band supported by a group of legacy barcode devices, so accepting this result would leave the primary fault without direct verification.
At a design studio in Berlin, this would verify Wireless client capacity and airtime fairness, not the failure reported in this scenario. The requested closure criterion instead concerns Wireless radio bands and channel availability: only supported clients associate on the authorized band and the RF plan uses permitted channels with acceptable signal and coverage.
