A switch port is flapping between up and down states. The administrator wants to determine if the issue is caused by the connected device or the switch port. What is the most effective way to troubleshoot this using Mist?

Disable the port to stop the flapping.

Initiate a packet capture on the port to see if the device is sending traffic.

Check the port's event logs for link up/down events and correlate with the device's activity.

Which action is required to make a new Juniper EX switch manageable through the Mist cloud before it can be adopted into a site?

Configure a static IP address on the switch's management interface

Upload a configuration file to the switch using the CLI

Enable LLDP on all switch ports

Claim the device using its serial number in the Mist portal

A network administrator is troubleshooting an issue where a user's device is not getting an IP address from a DHCP server connected to a Mist-managed switch. The administrator wants to use Mist AI features to help identify the cause. What is the most effective way to leverage Mist AI?

Review the switch's event logs for DHCP-related messages.

Check the switch's configuration to ensure DHCP snooping is enabled.

Initiate a packet capture on the port to see DHCP packets.

Use Marvis to ask a natural language question about the DHCP issue.

An administrator needs to upgrade the firmware on all EX2300 switches in a site to a new version that addresses a known bug. The upgrade must be performed during a maintenance window and should minimize disruption. What is the best approach in Mist?

Upgrade each switch individually via SSH during the maintenance window.

Wait for the next automatic firmware upgrade cycle from Mist.

Schedule the firmware upgrade for all switches in the site at the maintenance window using Mist's firmware management.

Use the Mist API to download the firmware and manually install it on each switch.

What is the purpose of the rollback feature in Mist for firmware upgrades?

To undo configuration changes made after the upgrade

To cancel a scheduled upgrade before it starts

To revert a switch to its previous firmware version if the upgrade causes issues

To restore the switch to factory default settings
