In the context of Mist Wired Assurance, what is the primary purpose of a port profile?

To automatically discover and onboard new switches onto the Mist network

To monitor real-time traffic statistics on a specific switch port

To assign a static IP address to a switch port for management access

To define a reusable set of port configuration parameters that can be applied to switch ports

A network administrator is troubleshooting a port that is not working as expected. The port is assigned a port profile that includes a specific VLAN, but the device connected to the port is not seeing the correct VLAN. What should the administrator check in the Mist dashboard?

The port profile assignment and the VLAN configuration in the profile.

The switch's system logs for any errors.

The device's MAC address in the Mist dashboard.

Which parameters can be configured within a port profile on a Mist-managed switch?

VLAN, speed, and duplex settings

Wireless SSID and encryption type

Routing protocol and autonomous system number

Switch hostname and management IP address

A network administrator is configuring a port profile for a device that requires a specific VLAN. The device is connected to a Mist-managed switch. What is the correct way to ensure the device is on the correct VLAN?

Configure the VLAN directly on the switch port using the CLI.

Use LLDP to automatically assign the VLAN.

Create a port profile with the VLAN and assign it to the port.

Use a switch-level template to set the VLAN for all ports.

An administrator needs to change the speed and duplex settings on a port profile that is assigned to several ports. After making the change, they notice that the ports are not coming up. What is the most likely reason?

The connected devices do not support the configured speed or duplex mode.

The ports are administratively down.

The VLAN configuration was also changed inadvertently.

The port profile was not saved after the change.
