An administrator connects VoIP phones to the same switch as the network PCs and printers. Which of the
following would provide the BEST logical separation of these three device types while still allowing traffic
between them via ACL?
Create three VLANs on the switch connected to a router
Define three subnets, configure each device to use their own dedicated IP address range, and then connect
the network to a router
Install a firewall and connect it to the switch
Install a firewall and connect it to a dedicated switch for each device type
A virtual local area network (VLAN) is a hardware-imposed network segmentation created by switches. VLANs
are used for traffic management. Communications between ports within the same VLAN occur withouthindrance, but communications between VLANs require a routing function.
