A manufacturer suspects the wireless hop on the client, because plant laptops fail the maintenance app on Wi-Fi and succeed on a docked cable. Which test should be added?
Select an answer to reveal the explanation.
Short Explanation
If a radio fails only when you unplug it and walk around, you test that radio, not the station across town. Put an Endpoint Agent test on the plant laptop so the client wireless hop is inside the measurement, matching failures that vanish on a docked cable. A data-center Enterprise Agent, a cloud DNS test, or a page load that never uses that wireless hop stays off the hop you suspect.
Full Explanation
Plant laptops fail the maintenance application on Wi-Fi and succeed on a docked cable, so the suspected hop is wireless on the client rather than a path that is common to both attachments. An Endpoint Agent test on the plant laptop includes that client wireless hop in the measurement and can be compared with the same laptop on the cable. An Enterprise Agent test that stays in the data center and never joins that Wi-Fi samples a healthy central vantage point and never rides the hop under suspicion. A DNS test from a cloud probe that does not attach to the plant wireless LAN measures name lookup from the cloud and cannot see the plant laptop's wireless hop. A page-load test that runs off the laptop and never uses the client wireless hop loads the maintenance app from somewhere else and skips the attachment method that separates failure from success. Exam caveat: when the same laptop works on a cable and fails on Wi-Fi, keep the test on that client and vary only the hop already isolated. Operational check: run the Endpoint Agent test on one plant laptop twice, once on the docked cable and once on Wi-Fi, and confirm the failure follows Wi-Fi while the data-center and cloud tests stay off that hop.
