Question 110
At a design studio in Berlin, engineers report that a 10-gigabit campus uplink negotiates unexpectedly at a lower rate despite policy being unchanged. The work affects wireless workstations and video conferences. Which post-change observation is the strongest acceptance evidence?
Explanation
Correct Answer
This observation tests the Campus uplinks, link speed and optics validation requirement at a design studio in Berlin. The expected result is that the intended uplink comes up at a supported speed and duplex with stable counters and correct neighbor identification. The necessary correction is to confirm supported optics, interface negotiation, cabling and peer compatibility before modifying higher-layer network services; a saved configuration alone would not prove it is working. In this case, the observed fault is that a 10-gigabit campus uplink negotiates unexpectedly at a lower rate despite policy being unchanged.
Incorrect Answers
At a design studio in Berlin, this would verify PoE budgets and AP or phone edge connectivity, not the failure reported in this scenario. The requested closure criterion instead concerns Campus uplinks, link speed and optics validation: the intended uplink comes up at a supported speed and duplex with stable counters and correct neighbor identification.
At a design studio in Berlin, the observation may be useful for a separate Zero-touch provisioning and initial management test, but it does not establish that a 10-gigabit campus uplink negotiates unexpectedly at a lower rate despite policy being unchanged has been resolved. The relevant check is the Campus uplinks, link speed and optics validation outcome.
At a design studio in Berlin, this measures a different network requirement, Aruba Central inventory and device onboarding. The case describes that a 10-gigabit campus uplink negotiates unexpectedly at a lower rate despite policy being unchanged, so accepting this result would leave the primary fault without direct verification.
