   A user in the finance department reports that their laptop consistently experiences a 5-10 second delay when moving from their office to the conference room. The network team uses client-level SLE analysis to investigate. Which client-level metric would most directly confirm a roaming problem versus a coverage problem?

   • AThe 'Coverage' SLE for that client, showing the received signal strength in the conference room.
   • BThe 'Roaming' SLE for that client, showing the number of transitions and the time spent in the 'roaming' state.
   • CThe 'Throughput' SLE for that client, showing the average data rate over the last hour.
   • DThe 'Capacity' SLE for that client, showing the number of other clients on the same AP in the conference room.

   A hospital's IT team notices that the Marvis Actions dashboard shows a new action titled 'Client Authentication Failures' affecting the radiology department. The action summary indicates that 15 unique clients failed 802.1X authentication in the last hour. What is the most appropriate first step for the network administrator to take using Marvis Actions?

   • ACheck the 'Capacity' SLE to see if the RADIUS server is being overwhelmed by too many authentication requests.
   • BImmediately reboot the access points in the radiology department to clear any cached authentication state.
   • CClick the action to view the affected clients and their failure reasons, then correlate with the RADIUS server logs.
   • DDisable 802.1X on the radiology SSID and switch to a pre-shared key to restore service quickly.

   A retail company has multiple stores, each with its own SSID. The network team wants to use Marvis Actions to proactively identify stores with a high number of client disconnects, but they want to avoid being overwhelmed by actions for minor issues. What is the most effective way to configure Marvis Actions to meet this need?

   • AReview the Marvis Actions dashboard daily and manually filter by the 'Client Disconnect' action type.
   • BUse the SLE dashboard to check the 'Roaming' SLE for each store and look for values below 90%.
   • CConfigure alert rules for 'Client Disconnect' with a threshold that triggers only when the number of disconnects exceeds a defined baseline.
   • DSet up a global alert for any client disconnect and apply it to all stores.

   A manufacturing plant has a 'Throughput' SLE at 85%, which is below the 90% target. The SLE dashboard shows that the issue is isolated to the '5 GHz' band. The administrator wants to determine if the problem is caused by a specific AP or a group of clients. What is the most efficient next step in the SLE dashboard?

   • AOpen the 'Roaming' SLE and look for excessive transitions on the 5 GHz band.
   • BCheck the 'Coverage' SLE for the 5 GHz band to see if there are coverage gaps.
   • CSwitch to the 'Capacity' SLE and check the number of clients on the 5 GHz band.
   • DDrill down into the Throughput SLE, filter by the 5 GHz band, and then sort the AP list by the 'Throughput' SLE score.
