   A school district's IT team is reviewing the roaming SLE for a large high school campus. The roaming SLE is 96%, but the team notices that the 'roam failures' metric shows 200 failures out of 5,000 roam attempts. The failures are concentrated on one building where a new batch of IoT devices was deployed. The IoT devices are configured to use 802.11r fast roaming. What is the most likely cause of the roam failures, and what should the team verify first?

   • AThe IoT devices are using a different PSK than the rest of the network, causing authentication failures; verify the WPA2 passphrase on the IoT SSID.
   • BThe building has a coverage gap between APs, so clients lose signal before they can complete a roam; check the coverage SLE for that building.
   • CThe APs in that building are overloaded, so roam attempts are being rejected; check the AP capacity SLE for that building.
   • DThe IoT devices may not fully support 802.11r, causing authentication failures during roaming; verify the devices' firmware and 802.11r compatibility.

   A hotel's front desk staff reports that guests in the conference center cannot reliably connect to the 'Guest' SSID, but guests in the lobby have no issues. The network administrator opens the Mist SLE dashboard and wants to quickly determine whether the problem is specific to the conference center or affects the entire property. Which dashboard view should the administrator use first?

   • AThe SLE overview page with a site filter for the conference center, compared against the property-wide view.
   • BThe radio frequency (RF) heatmap for the conference center to check for coverage gaps.
   • CThe client list filtered by the 'Guest' SSID, sorted by signal strength.
   • DThe alerts page to see if any SLE alerts have fired in the past 24 hours.

   A manufacturing plant's network administrator wants to be notified as soon as the coverage SLE for the warehouse floor drops below 95% for more than 10 minutes, but does not want alerts for brief, transient dips. Which configuration in Mist should the administrator use?

   • ACreate an SLE alert rule for the coverage SLE with a threshold of 95% and a duration of 10 minutes.
   • BSet the coverage SLE threshold to 95% in the site settings and enable email notifications for all SLEs.
   • CCreate a site-wide report for the coverage SLE and schedule it to run every 10 minutes.
   • DUse the Mist API to poll the coverage SLE every 5 minutes and write a custom script to send an email when the score is below 95%.

   What is the purpose of configuring SLE alerts in Mist AI?

   • ATo notify administrators when SLE scores drop below a threshold
   • BTo automatically fix network issues
   • CTo change the SLE calculation method
   • DTo generate reports for external stakeholders

   A hospital reports that clinicians in the radiology wing are experiencing slow image-loading times on their Wi-Fi 6 tablets. The Mist SLE dashboard shows the throughput SLE at 92% for the past 24 hours, but the coverage SLE is at 99.8%. When you drill into the throughput SLE, the top contributing factor is 'AP capacity' on two specific APs. Which action should you take first to address the reported issue?

   • AImmediately replace both APs with newer models that support more spatial streams.
   • BChange the SLE threshold for throughput from 95% to 90% so the alert no longer fires.
   • CDisable the 2.4 GHz radio on both APs to force all tablets onto the less congested 5 GHz band.
   • DReview the client count and channel utilization on the two flagged APs to determine if load balancing or additional APs are needed.
