8. Which one of the following event is not possible in wireless LAN.
Correct Answer is : collision detection
9. What is Wired Equivalent Privacy (WEP) ?
Correct Answer is : security algorithm for wireless networks
10. What is WPA?
Correct Answer is : wi-fi protected access
11. Which statement is true when VTP is configured on a switched network that incorporates VLANs?
Correct Answer is : VTP dynamically communicates VLAN changes to all switches in the same VTP domain.
12. Refer to the exhibit CH4-1 (on flash drive). What information can be learned from the output provided?
Correct Answer is : It verifies VTP advertisements are being exchanged.
13. Refer to the exhibit CH4-2. Which two facts can be confirmed by this output? (Choose two.)
Correct Answer is : If this switch is added to an established network, the other VTP-enabled switches in the same VTP domain will consider their own VLAN information to be more recent than the VLAN information advertised by this switch.
14. A network administrator is replacing a failed switch with a switch that was previously on the network. What precautionary step should the administrator take on the replacement switch to avoid incorrect VLAN information from propagating through the network?
Correct Answer is : Change the VTP domain name.
15. Which two statements are true about VTP pruning? (Choose two.)
Correct Answer is : Pruning can only be configured on VTP servers.
16. What are two features of VTP client mode operation? (Choose two.)
Correct Answer is : Unable to add VLANs
17. What does a client mode switch in a VTP management domain do when it receives a summary advertisement with a revision number higher than its current revision number?
Correct Answer is : It issues an advertisement request for new VLAN information.
18. Refer to the exhibit CH4-3 (on flash drive). Switch1 is not participating in the VTP management process with the other switches that are shown in the exhibit. What are two possible explanations for this? (Choose two.)
Correct Answer is : Switch1 is in a different management domain.
19. Refer to the exhibit CH4-4 (on flash drive). All switches in the network participate in the same VTP domain. What happens when the new switch SW2 with a default configuration and revision number of 0 is inserted in the existing VTP domain Lab_Network?
Correct Answer is : The switch operates as a VTP server, but does not impact the existing VLAN configuration in the domain.
20. Refer to the exhibit CH4-5 (on flash drive). Switches SW1 and SW2 are interconnected via a trunk link but failed to exchange VLAN information. The network administrator issued the show vtp status command to troubleshoot the problem. On the basis of the provided command output, what could be done to correct the problem?
Correct Answer is : The switches must be configured with the same VTP domain name.
