   A network admin is investigating a report of a user unable to connect to the corporate Wi-Fi. The admin opens the Mist event log and sees several events from the user's device: an 'authentication failure' event with severity 'warning', followed by a 'DHCP timeout' event with severity 'critical', and then a 'client disconnect' event with severity 'info'. The admin wants to prioritize which issue to investigate first. Based on the severity levels, which event should the admin focus on first?

   • AThe 'client disconnect' event, because it is the most recent.
   • BAll events equally, because they are all part of the same incident.
   • CThe 'DHCP timeout' event, because it has a 'critical' severity.
   • DThe 'authentication failure' event, because it is the first in the sequence.

   A network admin is investigating a pattern of intermittent disconnects in the warehouse. The admin has access to event logs and insights. The event logs show that clients are disconnecting from AP-Warehouse-1 and reconnecting to AP-Warehouse-2. The insights show a coverage insight indicating a weak signal area near the loading dock. What is the most effective way to combine this information to resolve the issue?

   • AUse the coverage insight to identify the weak signal area, then check the event logs to see if the disconnects occur when clients are in that area.
   • BOnly use the event logs to see the sequence of disconnects and reconnects.
   • CIgnore both and check the AP's configuration for errors.
   • DOnly use the coverage insight to identify the weak signal area and add an AP there.
