As you have learned, a subnet groups IP addresses so that clients on a large network can be logically organized into smaller networks. This is often accomplished with adding routers (or layer 3 switches) to the network or by using multiple ports on a single router (or layer 3 switch). By contrast, a VLAN groups ports on a layer ____ switch so that some of the local traffic on the switch is forced to go through a router. Therefore, VLANs are considered a Layer ____ solution for segmenting a network

A device uses a _______________ to determine which subnet or network it belongs to.

Subnet mask

is a smaller network within a larger network. A _______ is a logically visible subdivision of an IP network that is usually created for performance or security reasons and is usually implemented by a router (or other Layer 3 device).

Subnet/subnetwork

voice VLAN

Supports VoIP traffic, which requires high bandwidths, priority over other traffic, flexible routing, and minimized latency.

Each VLAN and subnet combination acts as a single broadcast domain. Although it is possible to do otherwise, network administrators find life much easier when they adhere to the following rule: 1 Broadcast Domain = 1 VLAN = 1 Subnet

True

In most situations, each VLAN is assigned its own subnet of IP addresses. This means that the subnet, working at Layer 3, includes the same group of hosts as the VLAN, working at Layer 2.

True

default VLAN

Typically preconfigured on a switch and initially includes all the switch's ports cannot be renamed or deleted

FC00:: /7

Unique local unicast

A __________ groups ports on a layer 2 switch so that some of the local traffic on the switch is forced to go through a router.

VLAN

________________ allows subnets to be further divided into smaller and smaller groupings until each subnet is about the same size as the necessary IP address space. This is often referred to as "Subnetting a Subnet".

VLSM

______ allows changes to a VLAN database on one switch, called the stack master, to be communicated to all other switches in the network. This provides network administrators with the ability to centrally manage all VLANs by making changes to a single switch.

VTP

Traditional subnetting reduces the waste of IP addresses, but results in multiple subnets that are ________________.

Routers ________ broadcast traffic.

A network administrator might segment a network into smaller networks for specific reasons. Select all of the following reasons a network administrator might segment a network into smaller networks.

enhance security improve performance simplify troubleshooting

Traffic between hosts on VLAN 1 and VLAN 2 must go through the router, which is called __________________ to be able to communicate. This simple VLAN configuration, where one router connects to a switch that supports multiple VLANs, is sometimes called an ROAS ("router-on-a-stick").

An _______________ switch provides plug-and-play simplicity with minimal configuration options and has no IP address assigned to it. ___________ switches are not very expensive, but their capabilities are limited and they cannot support VLANs.
