Chapter 11 Switching and VLANs

Question 1

Under what protocol is the disabled, blocking, and listening modes defined as discarding?

Answer 1

RSTP and it has faster convergence times.

Question 2

__ are used to break up broadcast domains in a pure switched network

Answer 2

VLANS

Question 3

Some features of VTP icnlude

Answer 3

Consistent VLAN configuration across all switches on the network

Accurate tracking and monitoring of VLANs.

Dynamic reporting of added VLANs to all switches in the VTP domain.

Adding VLANs using plug and play.

Question 4

How many VLANs can a trunk port carry traffic from at one time

Answer 4

1 to 40,94

Question 5

___ is a non operational port that is disabled administratively and does not take part in STP

Answer 5

Disabled

Question 6

A trunk link is either ___ or __ Mbps and is ___link

Answer 6

100 or 1000, PPP

Question 7

What is 802.q is used for what?

Answer 7

Frame Tagging with VLANs

Question 8

802.1d is what

Answer 8

STP

Question 9

___does not forward frames its just listens to BPDUs and will drop all other frames

Answer 9

Blocking

Question 10

___ is the time it takes for all ports to have transitioned to either forwarding or blocking modes

Answer 10

STP convergence

Question 11

ISL operates at what layer of the OSI model?

Answer 11

Layer2

Question 12

802.1W is

Answer 12

Rapid STP(RSTP)

Question 13

VTP transparent mode does

Answer 13

Gives the ability to configure switches to forward VTP info through trunk ports, but not accept info updates or to update their VTP databases.

Question 14

VLAN Trunking Protocol does?

Answer 14

Manages all configured networks across a switched internetwork and to maintain consistency throughout that network. It allows you to add, delete, or rename VLANs.

Question 15

VTP requires a ____

Answer 15

VTP server

Question 16

What does an access link do for a VLAN?

Answer 16

carries the traffic of only one VLAN.

Question 17

___the is when the switch port listens to BPDUs and learns all the paths in the switched network

Answer 17

Learning

Question 18

___listens to BPDUs to make sure no loops can occur on the network before passing the data frames

Answer 18

Listening

Question 19

Hypervisor or virtual machine monitor(VMM) is

Answer 19

Computer software, firmware, or hardware that creates and runs virtual machines.

Question 20

What ports can carry multiple VLANs at a time?

Answer 20

Trunk ports

Question 21

___ monitors the network to find all links and makes sure that no loops occur by shutting down redundant links on layer2 devices.

Answer 21

STP

Question 22

What allows for VLANs to be multiplexed over a trunk link through external encapsulation?

Answer 22

ISL

Question 23

CRC stands fo ____ and is it used for

Answer 23

Cycle redundancy check. CRC allows for the interconnecting of multiple switches while still maintaining VLAN info as traffic travels between switches and trunk links.

Question 24

Inter-Switch Link(ISL)

Answer 24

Is a way of explicitly tagging VLAN information onto an Ethernet frame.

Question 25

How does 802.q work?

Answer 25

It inserts a field into the frame to identify the VLAN.
