A network administrator is monitoring a switch that has been experiencing intermittent high CPU utilization. The Mist portal shows that the CPU spikes correlate with periods of high network traffic. The administrator wants to determine if the high CPU is causing packet loss. Which approach should the administrator use?

Review the switch's interface statistics for dropped packets during the same time periods as the CPU spikes.

Use the Mist AI insights to see if there are any recommendations for reducing CPU usage.

Reboot the switch to clear the CPU spikes and then monitor for packet loss.

Check the switch's temperature and fan status to see if the switch is overheating.

Which task can an administrator perform through the Mist portal for a managed EX switch?

Push configuration templates to multiple switches at once

Directly edit the switch's Junos configuration file in a raw text editor

Replace the switch's operating system with a third-party OS

Manually assign IP addresses to every connected client device

How does Mist provide visibility into wired client connectivity?

By using GPS to locate each client device

By tracking client device information and the switch port they are connected to

By capturing and analyzing all client traffic in real time

By requiring clients to install a software agent on their devices

What does PoE status monitoring in Mist allow an administrator to observe?

The network bandwidth used by PoE devices

The amount of electricity consumed by the switch itself

The temperature of the power supply unit

The power being delivered to connected devices such as IP phones and cameras
