Question 10

Access-link devices know what VLAN they are part of, TRUE or FALSE

Answer 10

False, they just see a single broadcast domain.

Question 11

How many VLANS can a trunk port carry?

Answer 11

4094

Question 12

List the devices that use trunk links to connect

Answer 12

1) Switch to Switch
2) Switch to Router
3) Switch to Server

Question 13

Name the two methods switches use to identify VLANS over a trunk-link?

Answer 13

Inter-switch Link and IEEE 802.1Q

Question 14

If you had multi-vendor switches interlinked by trunks, which method of VLAN identification or tagging would you employ?

Answer 14

IEEE 802.1Q

Question 15

Answer 15

12-bits

Question 16

What is the basic goal of VLAN Trunking Protocol? (VTP)

Answer 16

Manage all configured VLANS across a switched internetwork.

Question 17

For VTP servers to share/manage VLAN informantion, what 4 things are required?

Answer 17

1) VT switches configured on same domain
2) One switch has to be designated the VTP server
3) A VTP password has to be configured
4) No router required

Question 18

Updated VTP configurations are indicated by what?

Answer 18

Configuration Revision number

Question 19

Name the 3 VTP modes. Which one isn’t saved in NVRAM?

Answer 19

1) Server
2) Client - not saved in NVRAM
3) Transparent

Question 20

In VTP Client mode you can add or change VLANs, TRUE or FALSE?

Answer 20

FALSE. Only receive and forward updates to other clients.

Question 21

Why might you use VTP Transparent mode on a switch?

Answer 21

If you needed a switch that was outside of a VTP domain to forward VTP advertisements to other VTP clients or servers.

Answer 22

VLAN 1

Question 23

What is the default gateway setting on a switch used for?

Answer 23
