Module 3-Creating Vlans

What is the primary purpose of a vlan?

• To reduce collision domains.

• To separate tagged from untagged traffic.

• To combine multiple types of network traffic into one broadcast domain.

• To break up a large network layer 2 broadcast domain into smaller broadcast domains.

When does vlan tagging occur?

• Frames are tagged when leaving the PC to the switch.

• Frames are tagged when received on a switch port that is assigned to a vlan but destined for another network.

• Frames are tagged by the router after the switch determines the destination address is on a remote network.

• Tagged traffic never occurs anymore on modern intermediary devices.

Port Fa0/11 on a switch is assigned to VLAN 30. If the command no switchport access vlan 30 is entered on the Fa0/11 interface, what will happen?

• Port Fa0/11 will be shutdown.

• An error message would be displayed.

• Port Fa0/11 will be returned to VLAN 1.

• VLAN 30 will be deleted.

Which command would you use to verify that subinterfaces or SVI interfaces created for inter-vlan routing are in the routing table?

• show interfaces [int-id] switchport

• show ip route

• show vlan

• show ip int brief

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

• 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

• show interfaces trunk

• show mac address-table interface Fa0/1

Which command sets switch ports so they require manual configuration to specify trunking or nontrunking?

• dynamic desirable

• dynamic auto

• nonegotiate

• trunk
