_____ is a method to support multiple VLAMs allowing traffic from those VLAMs to cross a single link, either using the Cisco ISL protocol with IEEE 802.1 Q protocol

Trunking

1

From one perspective a ____ includes all the user devices servers switches routers cables and wireless access points in one location

LAN

2

A _____ includes all devices in the same broadcast domain

LAN

3

A _____ _____ includes a set of all LAN connected devices so that when any of the devices send a broadcast frame, all the other devices get a copy of the frame

Broadcast domain

4

Without _____ a switch considers all it's interfaces to be in the same broadcast them

VLAN

5

With _____ a switch can configure some interfaces into one broadcast a main summits another creating multiple broadcast domains

VLANs

6

Creating smaller ____ has a number benefits including reduce CPU overhead reduced security risks improve security for hosts more flexible design quicker problem-solving and reducing the workload for spamming tree protocol

VLANs

7

When using VLANs in networks that have multiple interconnected switches, the switches need to use VLAN _______ on the links between the switches

Trunking

8

VLAN trunking causes the switches to use a process called VLAN ______ by which the sending switch adds another Header to the frame before sending it over the trunk

Tagging

9

VLAN ID

VLAN identifier

10

The use of _____ allows switches to pass frames from multiple VLANs over a single physical connection by adding a small header to the ethernet frame

Trunking

11

Cisco supported two different trunking protocols over the years ______ and ______

ISL (inter-switch link) and 802.1Q

12

ISL

Inter-switch link

13

Today the more popular trucking protocol is _____

802.1Q

14

VTP

VLAN trunking protocol

15

The rules for which switches can use extended range VLANs depends on the configuration of the ______

VTP (VLAN trunking protocol

16

802.1Q defines one special VLAN ID on each trunk as the _______ which is defaulted When A side sees a frame with no header

Native

17

The 802.1Q native VLAN provide some interesting functions, mainly to support connections to devices that do not understand

Trunking

18

Some LAN switches forward data based on layer two logic, which go by the name _____ __ _____

Layer 2 switch

19

Some switches can do functions like a router using additional logic defined by layer 3 protocols, these switches go by the name _____ _____ or layer 3 switch

Multilayer switch

20

When including VLANs and I campus LAN design, the devices in a VLAN need to be in the same _____

Subnet

21

layer 2 switches will not forward data between two

VLANs

22

The job forwarding data into and out of a VLAN fall to a ______

Router

23

Instead of switching layer 2 ethernet frames between two VLANs, the network must route layer ____ packets between two subnetwork

3

24

PPS

Packets per second

25

When the router has a single physical link connected to the LAN switch, this design is sometimes called ____-___-___-____

Router on a stick

26

VTP

VLAN Trunking Protocol

27

Each switch can use one of three ____ modes: server client or Transparent

VTP

28

DTP

Dynamic trunking protocol

29

Trunking administrative mode options _____ always act as an access (non-trunk) port

Access
