Question 120
At Dunhaven University, the campus systems team is preparing a multi-building classroom network upgrade. The operational constraint is classroom Wi-Fi and VoIP availability. The owner reports that the correction is complete for this issue: A zero-touch switch cannot contact cloud onboarding services at first boot. Which result BEST demonstrates that this specific issue was resolved?
Explanation
Correct Answer
A factory-default test device reaches onboarding services and completes authorized provisioning. This is the relevant acceptance observation for the reported issue: A zero-touch switch cannot contact cloud onboarding services at first boot. The intended corrective choice is: Verify management addressing, DNS, outbound reachability and any required onboarding service access. At Dunhaven University, this outcome verifies actual operation under classroom Wi-Fi and VoIP availability, rather than only a ticket marked complete.
Incorrect Answers
Central reports the intended group assignment and the switch reflects the approved site configuration. Such an observation would verify a separate issue: A switch is online in Central but inherits a generic configuration rather than the planned site configuration. It would follow the distinct action: Place it in the correct group and site and verify the relevant template or group settings. Here the reported failure is A zero-touch switch cannot contact cloud onboarding services at first boot. The decisive result for Dunhaven University must instead be: A factory-default test device reaches onboarding services and completes authorized provisioning.
The switch's running configuration and Central state agree on all governed settings after reconciliation. Such an observation would verify a separate issue: A switch appears online in Central but configuration status reports out of sync after a manual change. It would follow the distinct action: Inspect intended configuration ownership and reconcile drift without silently overwriting a valid device exception. Here the reported failure is A zero-touch switch cannot contact cloud onboarding services at first boot. The decisive result for Dunhaven University must instead be: A factory-default test device reaches onboarding services and completes authorized provisioning.
A rendered configuration preview and post-push comparison match the correct switch and ports. Such an observation would verify a separate issue: A template change produces unexpected interface commands on one stack because its variables reference the wrong device. It would follow the distinct action: Validate Central template variables against switch serial numbers, stack identity and interface inventory before push. Here the reported failure is A zero-touch switch cannot contact cloud onboarding services at first boot. The decisive result for Dunhaven University must instead be: A factory-default test device reaches onboarding services and completes authorized provisioning.
