A network admin is troubleshooting a switch that is intermittently losing connectivity. The admin has checked the interface statistics and sees no errors. The switch is part of a stack. The admin suspects a stack member is failing. What should the admin do?

Review the switch's firmware version for stack bugs.

Check the stack status and member health in Mist.

Reboot the entire stack to reset all members.

Check the switch's configuration for stack-related settings.

What is the role of a port profile in Mist switch configuration?

To assign an IP address to a switch port

To manage the firmware version of a switch

To monitor the traffic on a specific port

To define the settings for a switch port based on the type of device connected

How does Mist help ensure switches are running a compliant firmware version?

By blocking switches that are not compliant

By automatically upgrading switches without administrator intervention

By requiring all switches to use the same firmware version

By providing firmware upgrade recommendations and compliance reports

A user reports that they cannot access the network on a specific port. The admin checks Mist and sees that the port is up but the user's device is not getting an IP address. The admin suspects a VLAN mismatch. The switch is configured with a port profile that assigns VLAN 10, but the DHCP server is on VLAN 20. What is the most likely cause and solution?

The user's device is faulty; try a different device.

The port profile is incorrect; change the port profile to assign VLAN 20.

The switch's uplink is down; check the uplink status.

The DHCP server is down; check the DHCP server status.

What is the typical process for upgrading switch firmware in Mist?

Use the CLI to copy the firmware from a TFTP server

Download the firmware to a USB drive and manually install it on each switch

Wait for the switch to automatically upgrade itself

Select the switch, choose the target firmware version, and schedule the upgrade
