A network administrator is using Mist Wired Assurance to monitor a network with multiple switches. Mist AI has detected an anomaly on one switch, but the administrator is not sure if it is a real issue or a false positive. What should the administrator do to validate the anomaly?

Contact Mist support to ask if the anomaly is real.

Ignore the anomaly because Mist AI is always accurate.

Check the switch's live telemetry data in the Mist portal to see if the anomaly correlates with any unusual behavior.

Reboot the switch to clear the anomaly.

A network engineer is troubleshooting a link between two switches that is up but experiencing intermittent packet loss. The Mist portal shows the link is up at 1Gbps, but there are CRC errors on the port. What should the engineer do to resolve the issue?

Check the switch's CPU and memory utilization to see if it is overloaded.

Disable and re-enable the port to clear the errors.

Change the speed and duplex settings on both switches to force a specific mode.

Replace the network cable connecting the two switches.

A network administrator is using Mist Wired Assurance to monitor a network. They want to be alerted when a switch's CPU utilization exceeds 80% for more than 5 minutes. What should the administrator configure?

A SNMP trap to send CPU utilization data to a network management system.

A scheduled report that shows CPU utilization trends.

A webhook to send CPU utilization data to an external monitoring system.

A custom alert rule in the Mist portal that specifies the CPU utilization threshold and duration.

A network administrator wants to track the location of wired devices in a building to assist with asset management. The Mist portal shows the switch and port to which each device is connected. What additional information does Mist provide to help with location tracking?

The distance from the device to the switch.

The physical location of the switch, such as the building and floor, if configured.

The exact room number where the device is located.

The GPS coordinates of each connected device.

What type of information can Mist provide about a wired client's location?

The client's Wi-Fi signal strength

The switch and port to which the client is connected

The precise GPS coordinates of the client

The physical address of the building where the client is located
