The port becomes inactive

2. In which memory location are the VLAN configurations of normal range VLANs stored on a Catalyst switch?

flash

3. An administrator is investigating a failure on a trunk link between a Cisco switch and a switch from another vendor. After a few show commands, the administrator notices that the switches are not negotiating a trunk. What is a probable cause for this issue?

Switches from other vendors do not support DTP.

4. What is the purpose of the vlan.dat file on a switch?

It holds the VLAN database.

5. What is the purpose of setting the native VLAN separate from data VLANs?

A separate VLAN should be used to carry uncommon untagged frames to avoid bandwidth contention on data VLANS.

6. When a Cisco switch receives untagged frames on a 802.1Q trunk port, which VLAN ID is the traffic switched to by default

native VLAN ID

7. A network administrator is determining the best placement of VLAN trunk links. Which two types of point-to-point connections utilize VLAN trunking? (Choose two.)

between two switches that utilize multiple VLANs

7. A network administrator is determining the best placement of VLAN trunk links. Which two types of point-to-point connections utilize VLAN trunking?

between a switch and a server that has an 802.1Q NIC

What are three primary benefits of using VLANs?

security .cost reduction .improved IT staff efficiency

9. On a Cisco switch, where is extended range VLAN information stored?

running configuration file

10. In which location are the normal range VLANs stored on a Cisco switch by default?

flash memory

11. Which distinct type of VLAN is used by an administrator to access and configure a switch?

management VLANmanagement VLAN

12. For what reason would a network administrator use the show interfaces trunk command on a switch?

to view the native VLAN

13. Where is the vlan.dat file stored on a switch?

in flash memory

14. If an organization is changing to include Cisco IP phones in its network, what design feature must be considered to ensure voice quality?

A separate VLAN is needed for voice traffic.

15. A Cisco switch currently allows traffic tagged with VLANs 10 and 20 across trunk port Fa0/5. What is the effect of issuing a switchport trunk allowed vlan 30 command on Fa0/5?

It allows only VLAN 30 on Fa0/5.

16. Which three statements accurately describe VLAN types? (Choose three).

A management VLAN is any VLAN that is configured to access management features of the switch, After the initial boot of an unconfigured switch, all ports are members of the default VLAN., An 802.1Q trunk port, with a native VLAN assigned, supports both tagged and untagged traffic

17. Which type of VLAN is used to designate which traffic is untagged when crossing a trunk port?

Native

18. What are two primary benefits of using VLANs? (Choose two.)

Cost reduction, Improved IT staff efficienc

19. Which command displays the encapsulation type, the voice VLAN ID, and the access mode VLAN for the Fa0/1 interface?

show interfaces Fa0/1 switchport

20. What must the network administrator do to remove FastEthernet 0/1 from VLAN 2 and assign it to VLAN 3?

Enter the switchport access vlan 3 interface config command on Fa0/1.

21. A Cisco Catalyst switch has been added to support the use of multiple VLANs as part of an enterprise network. The network technician finds it necessary to clear all VLAN information from the switch in order to incorporate a new network design. What should the technician do to accomplish this task?

Delete the startup configuration and the vlan.dat file in the flash memory of the switch and reboot the switch

22. Which two characteristics match extended range VLANs? (Choose two

They are saved in the running-config file by default, VLAN IDs exist between 1006 to 4094.

23. What happens to switch ports after the VLAN to which they are assigned is deleted?

The ports stop communicating with the attached devices.

24. You must configure a trunk link between a Cisco Catalyst 2960 switch to another vendor Layer 2 switch. Which two commands should be configured to enable the trunk link? (Choose two.)

switchport mode trunk, switchport nonegotiate
