A network administrator is configuring a new VLAN for the guest wireless network. The guest network should have internet access but should not be able to access internal corporate resources. The administrator has created a VLAN with ID 20 and assigned an IP subnet. Which additional configuration is required to enforce the isolation?

Connect the guest VLAN to a separate physical switch.

Configure an access control list (ACL) on the router or layer-3 switch to block traffic from VLAN 20 to internal VLANs.

Assign the guest VLAN to the same subnet as the internal network.

Disable the DHCP server for the guest VLAN.
