   A school district's network team sees a Marvis Action titled 'DNS Failures' affecting the staff SSID. The action reports that 30 clients are failing to resolve DNS queries. The team suspects a misconfigured DNS server on the network. What is the most efficient way to confirm this hypothesis using Wi-Fi Assurance tools?

   • AClick the Marvis Action to see the list of affected clients and the specific DNS server IP they are using, then verify that IP in the DHCP scope.
   • BCheck the 'Coverage' SLE to see if the affected clients have poor signal, which might cause DNS timeouts.
   • CReboot the access points to clear the DNS cache and see if the issue resolves.
   • DDisable the staff SSID and recreate it with a different name to reset the network settings.

   A warehouse reports that forklift-mounted scanners intermittently lose connectivity in a specific aisle. The SLE dashboard shows the 'Coverage' SLE at 95% overall, but the 'Roaming' SLE is at 70%. Marvis Actions shows a 'Sticky Client' anomaly for several scanners. What is the most likely root cause and the best next step?

   • AThe RADIUS server is rejecting the scanners' authentication; check the authentication SLE for failures.
   • BThe aisle has a coverage gap; add an additional AP to improve the signal in that specific location.
   • CThe scanners are experiencing interference from the warehouse equipment; change the channel width to 40 MHz.
   • DThe scanners are associating to a distant AP and not roaming to a closer one; adjust the RSSI threshold for the scanners' SSID.
