Chapter 3 test

 VLANS group hosts _____________________ logically or physically?  Logically—regardless of physical location  Devices in one VLAN do not hear the broadcasts from devices in another VLAN

 A Management VLAN is any VLAN that is configured to access management features of the switch.  After initial boot of an unconfigured switch, all ports are members of the __________________  Management VLAN

 VLAN 1 is always used as the management VLAN and you cannot change management to a different number (T or F)  False…you can change it to a different number, and in fact you should

 Why do you set up trunk lines?  The are used between two switches that utilize multiple VLANs to carry the traffic of ALL VLANs

 If you have traffic going between two computers that are both on the same VLAN and both attached to the same switch, will the switch add a VLAN tag to the frame?  No it is not needed

 You have a switch that doesn’t have VLANs set up. You enter the following command on interface fa0/18 of the switch  Switchport access vlan 20  What effect does this have on the switch in regard to VLANs?  VLAN 20 will be created automatically

 What command is used to remove a VLAN from a switch?  No vlan 20

 If a port on a switch has been assigned to the VLAN 30 and then the command is negated by entering no switchport access vlan 30, what will happen to the port?  It will return to VLAN1

 Which command is used to display the encapsulation type and the access mode of a port  Show interface fa0/1 switchport

 If a port belongs to VLAN 2 and the network administrator wants to reassign it to the new VLAN 3, what must be done?  Enter the command switchport access vlan 3  You do NOT need to remove it from the old vlan first, just reassign it

 If you need to clear all VLAN information from the swtich to incorporate a new network design, how should you accomplish this??  Delete the startup configuration file and the vlan.dat file in the flash memory of the switch and reboot the switch

 If you have a trunk port and you issue the command switchport trunk allowed vlan 30 on the trunk port interface, what traffic will go to the other switch ??  Only VLAN 30 TRAFFIC

 If you have multiple VLANs and do not specify specific vlans allowed on the trunk, which VLANs will be allowed across the trunk??  All VLANs will be allowed

 If you have a Cisco switch and a non-Cisco switch, what command should you enter to prevent the transfer of DTP frames?  S1(config-if)#switchport nonegotiate

 When should you disable DTP while managing a local area network?  When connecting a Cisco switch to a non-Cisco switch  On links that should not be trunking

 What happens to a port that is associated with VLAN 10 when the administrator delete VLAN 10 from the switch?  The port becomes inactive

 What is a good practice to help prevent VLAN hopping attacks?  Change the native VLAN number to one that is distinct from all user VLANs and is not VLAN1  Daisable DTP autonegitiation on end-user ports
