1. What happens to a port that is associated with VLAN 10 when the administrator deletes VLAN 10 from the switch?
- The port creates the VLAN again.
- The port goes back to the default VLAN.
- The port automatically associates itself with the native VLAN.
- The port becomes inactive.
2. In which memory location are the VLAN configurations of normal range VLANs stored on a Catalyst switch?
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?
- Both switches are in nonegotiate mode.
- Switches from other vendors do not support DTP.
- Both switches are in trunk mode.
- DTP frames are flooding the entire network.
4. What is the purpose of the vlan.dat file on a switch?
- It holds the VLAN database.
- It holds the running configuration.
- It holds the operating system.
- It holds the saved configuration.
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.
- The security of management frames that are carried in the native VLAN can be enhanced.
- The native VLAN is for carrying VLAN mnanagement traffic only.
- The native VLAN is for routers and switches to exchange their management information, so it should be different from 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?
- management VLAN ID
- data VLAN ID
- native VLAN ID
- unused 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
- between a switch and a server that has an 802.1Q NIC
- between a switch and a network printer
- between two switches that share a common VLAN
- between a switch and a client PC
8. What are three primary benefits of using VLANs? (Choose three.)
- end user satisfaction
- cost reduction
- a reduction in the number of trunk links
9. On a Cisco switch, where is extended range VLAN information stored?
- running configuration file
- startup 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?
- data VLAN
- default VLAN
- native VLAN
- management VLAN
12. For what reason would a network administrator use the show interfaces trunk command on a switch?
- to view the native VLAN
- to examine DTP negotiation as it occurs
- to display an IP address for any existing VLAN
- to verify port association with a particular VLAN
13. Where is the vlan.dat file stored on a switch?
- in NVRAM
- in flash memory
- in RAM
- on the externally attached storage media or internal hard drive
14. If an organization is changing to include Cisco IP phones in its network, what design feature must be considered to ensure voice quality?
- Voice traffic needs to be tagged with the native VLAN.
- A separate VLAN is needed for voice traffic.
- Voice traffic and data traffic require separate trunk links between switches.
- Additional switch ports that are dedicated to Cisco IP phones are required.
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 a native VLAN of 30 to be implemented on Fa0/5.
- It allows VLANs 10, 20, and 30 on Fa0/5.
- It allows only VLAN 30 on Fa0/5.
- It allows VLANs 1 to 30 on Fa0/5.
