Question 120
During a planned campus-network change at a public library in Portland, operators discover that two connected devices report different advertised capabilities and the team has not checked their negotiated link settings. The design must preserve staff and visitor wireless access. What evidence should the engineer request after the repair?
Explanation
Correct Answer
This observation tests the Campus uplinks, link speed and optics validation requirement at a public library in Portland. 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 two connected devices report different advertised capabilities and the team has not checked their negotiated link settings.
Incorrect Answers
At a public library in Portland, this measures a different network requirement, PoE budgets and AP or phone edge connectivity. The case describes that two connected devices report different advertised capabilities and the team has not checked their negotiated link settings, so accepting this result would leave the primary fault without direct verification.
At a public library in Portland, the observation may be useful for a separate Aruba Central inventory and device onboarding test, but it does not establish that two connected devices report different advertised capabilities and the team has not checked their negotiated link settings has been resolved. The relevant check is the Campus uplinks, link speed and optics validation outcome.
At a public library in Portland, this measures a different network requirement, Zero-touch provisioning and initial management. The case describes that two connected devices report different advertised capabilities and the team has not checked their negotiated link settings, so accepting this result would leave the primary fault without direct verification.
