A network engineer is deploying a new EX switch in a remote office. The switch is not yet claimed in Mist. The engineer wants to configure the switch with the correct VLANs and port settings before it is shipped to the remote office. How can the engineer accomplish this?

Use the Mist mobile app to configure the switch before it is powered on.

Ship the switch to the remote office and configure it locally using the CLI.

Wait until the switch is on-site and then use the Mist portal to configure it.

Use the Mist portal to pre-provision the switch by entering its serial number and applying configuration templates.

A network administrator is monitoring a switch that is running at high temperature. The Mist portal shows the temperature is above the recommended threshold. What should the administrator do first?

Reboot the switch to reset the temperature sensors.

Increase the switch's power supply to improve cooling.

Disable PoE on all ports to reduce heat generation.

Check the switch's fan status and the ambient temperature in the wiring closet.
