   • ACreate a single alert rule for all alerts and use Slack's internal routing rules to filter messages.
   • BCreate a single webhook notification channel that posts to both Slack channels.

   An admin notices a threshold alert for 'High Retransmission Rate' on a specific access point. The alert has been firing for 30 minutes. The admin also sees an anomaly alert for 'Increased Roaming Failures' on the same AP. Which of the following is the MOST likely root cause, and which Mist feature should be used to confirm it?

   • AA misconfigured neighbor AP; confirm by checking the neighbor list and channel utilization in the Mist topology view.
   • BA client driver issue; confirm by checking the client's connection history and driver version in Client Insights.
   • CAn authentication server problem; confirm by checking the RADIUS server's response time in the Mist WAN insights.
   • DA faulty AP radio; confirm by checking the AP's RF health and signal-to-noise ratio (SNR) in the Mist radio insights.

   A company's branch office reports intermittent connectivity. The Mist dashboard shows a threshold alert for 'High Retransmission Rate' on the WAN interface of the branch's SRX series device. The alert has been firing for the past hour. The admin also sees a separate anomaly alert for 'Increased DNS Query Failures' on the same device. Which troubleshooting step is MOST likely to identify the root cause?

   • AAcknowledge the threshold alert and clear it, as the anomaly alert is the more critical one to investigate.
   • BCheck the Mist alarm log for the specific client MAC addresses involved in the retransmissions.
   • CCorrelate the timestamps of both alerts and check the Mist WAN Edge insights for packet loss and latency graphs during that period.
   • DImmediately reboot the SRX device to clear the alerts and restore connectivity.
