Which of the following is a potential risk of a misconfigured guest VLAN?

Authenticated devices being placed in the guest VLAN

Unauthenticated devices gaining access to the corporate network

The switch losing all VLAN configurations

Voice traffic being sent to the guest VLAN

A switch is configured with 802.1X and a guest VLAN. A device that does not support 802.1X is connected and is placed in the guest VLAN. The device can access the internet but cannot reach a printer that is also in the guest VLAN. What is the most likely cause?

The guest VLAN is not allowed on the uplink

The device is not receiving an IP address from DHCP

The switch port is in trunk mode

The printer is not in the same subnet as the guest VLAN

A device is failing 802.1X authentication and is not being placed in the guest VLAN. What is a common cause?

The switch is not running 802.1X

The guest VLAN is not configured on the interface

The device is not sending any traffic

The device is using a static IP address

A company is deploying a guest VLAN for visitors. The security team is concerned about visitors accessing sensitive data. Which of the following is a recommended security practice?

Apply an ACL to the guest VLAN to block access to internal subnets

Use the same VLAN as the corporate network

Allow guest VLAN traffic to reach all internal subnets

Disable the guest VLAN after business hours

What is the primary purpose of a guest VLAN in a Juniper switch configuration?

To offer limited network access to devices that fail authentication or do not attempt it

To segregate voice traffic from data traffic on the same interface

To provide full network access to all devices that successfully authenticate via 802.1X

To automatically assign a VLAN based on the device's MAC address
