In a Marvis query, what is the purpose of adding a time range such as 'last 24 hours'?

To compare current network performance with historical baselines

To specify the period over which Marvis should analyze data and return insights

To limit the query to only the most recent data, making results faster to retrieve

To schedule the query to run automatically at a later time

A hospital IT team wants to verify that all IoT medical devices on the 'Medical-IoT' SSID are connecting successfully. They need a query that returns only devices on that SSID. Which Marvis query is most appropriate?

show clients on ssid Medical-IoT

Which element is commonly used in a Marvis query to narrow results to a specific device or group?

A threshold value such as 'RSSI > -70 dBm'

A sort order such as 'ascending' or 'descending'

A verb such as 'show' or 'list'

A filter such as 'site:Building A' or 'device:AP-01'

A company's employees report that video conferencing calls are choppy. The administrator runs 'show network performance in last 1 hour' and sees high latency but normal packet loss. The suggested action is 'check for WAN congestion'. However, the administrator also notices that the issue occurs only during specific times of day. What should the administrator do next?

Ignore the issue because packet loss is normal.

Reboot the WAN router to clear any temporary issues.

Investigate WAN congestion during the reported times to identify the cause of high latency.

Increase the bandwidth of the WAN link immediately.

Which Marvis query would be most useful for diagnosing a sudden increase in client disconnects on a specific floor?

'List all access points in the building'

'Show network throughput for the last week'

'Display the firmware version of all switches'

'Show client disconnects on floor 2 in the last 2 hours'
