Which VLAN doesn't get tagged when going across a trunk link?
Voice VLAN
Default VLAN
Native VLAN
Extended VLAN
Everyone on the same VLAN belongs to the same _____ (choose two)
broadcast domain
ip network
layer 2 segment
collision domain
Even though it's against best practices, the network admin decided to use VLAN1 as management VLAN in the network. To identify it, the admin renames the VLAN to "Management" but gets an error.....Why?
Cisco doesn't allow VLAN1 to be used for management
There aren't any access ports configured in VLAN1
The VLAN must be deleted and recreated with the new name
VLAN1 is immutable and can't be deleted or changed in any way
Which of the following is not a benefit of VLANs?
improved security
lower costs
smaller broadcast domains
ability to route traffic between subnets
reduced cost
True or False: Because an access port can only be assigned to one VLAN, an end user with a PC workstation and an IP phone requires two switch ports.
True
False
Which of the following are legit types of VLANs? (choose all that apply)
Data VLAN
Default VLAN
Dedicated VLAN
Voice VLAN
Native VLAN
True or False: Native VLAN does not get tagged when forwarded over a trunk link.
True
False
What is required to allow Host A and Host B to communicate?
802.1Q trunk
layer 3 device
ARP reply
nothing, the hosts are connected to the same switch
True or False: If the native VLAN is not the same on every trunk in the switched network, then communication will fail.
True
False
What two commands could you use to verify an interface is configured as a trunk?
show interfaces trunk
show trunks

What command do you use to configure a switchport on a Catalyst 2960 for voice on VLAN 20?
#switchport access voice 20
#switchport mode voice 20
#switchport access vlan 20
#switchport voice vlan 20
True or False: Because an access port can be assigned to one VLAN, an end user with a PC and an IP phone needs two switch ports.
True
False
The links on one switch are configured as passive. What protocol and mode must be configured on the other side to form an etherchannel?

Auto
Passive
Desirable
Active
You have configured an etherchannel consisting of 3 fastethernet links between two switches. What would happen if one of the fastethernet links fails?
the etherchannel will fail

When an etherchannel is configured, what mode will force an interface into a port-channel without negotiating with the other end?
LACP
PAgP
No-negotiate
ON
You have an etherchannel with two links built between two switches. Which link will spanning tree block?
