A computer is connected directly to a switch port that is configured as an access port. Which description best explains how that port carries traffic?

A
It carries traffic for every VLAN on the switch.
B
It carries traffic for one VLAN and is typically used for an end device.
C
It routes traffic between VLANs.
D
It prevents all communication with other devices.

On the example switch, GigabitEthernet1/0/3-4 connect guest computers and should be access ports in VLAN 20. Which command assigns the interface range to VLAN 20?

A
switchport mode access
B
switchport access vlan 10
C
switchport access vlan 20
D
switchport mode trunk

A staff computer in VLAN 10 needs to communicate with a guest computer in VLAN 20. What network function is required for traffic to pass between them?

A
Add a router or Layer 3 switch to route traffic between the VLANs.
B
Put both devices on the same physical switch; that is sufficient.
C
Change both ports to access mode; that enables routing.
D
Use show vlan brief to enable communication between the VLANs.

You need to check whether GigabitEthernet1/0/1 is in access mode and which access VLAN it uses. Which command is the most direct check?

A
show vlan brief
B
copy running-config startup-config
C
show running-config
D
show interfaces GigabitEthernet1/0/1 switchport

Choose all

Select all commands that can help verify the example switch's VLAN membership or an interface's access-port settings.

A
Use show vlan brief to check VLANs and their listed access ports.
B
Use show interfaces GigabitEthernet1/0/1 switchport to inspect that port's mode and access VLAN.
C
Use copy running-config startup-config to display VLAN membership.
D
Use show vlan brief to determine whether inter-VLAN routing is configured.

Select all statements consistent with testing whether two endpoints in VLAN 10 can communicate.

A
The endpoints are active, in the same VLAN and IP subnet, and host firewalls and other settings allow communication.
B
The endpoints are in different VLANs, which guarantees direct Layer 2 communication.
C
The switch port is up and the endpoint is connected to the expected port.
D
The endpoints are in the same VLAN, so their IP settings do not matter.

True or false

True or false: VLAN membership by itself should be treated as a substitute for security controls.

A
True
B
False

True or false

A staff computer in VLAN 10 and a guest computer in VLAN 20 are correctly connected to their assigned access ports but cannot communicate. Explain why VLAN membership alone is not enough and what is needed for communication between them.

A computer is connected to a switch port configured as an access port. Which description best matches the role of that port?

A
It carries traffic for all VLANs on the switch.
B
It carries traffic for one VLAN and is typically used for an end device.
C
It routes traffic between VLANs.
D
It creates a separate physical network for each VLAN.

A team wants to logically separate groups of devices that are connected to the same physical switch. Which VLAN function supports this goal?

A
They ensure every device uses a separate physical switch.
B
They assign IP addresses to all connected devices.
C
They divide a switched network into separate Layer 2 broadcast domains.
D
They automatically route traffic between separate IP subnets.

A device in VLAN 10 needs to communicate with a device in VLAN 20. What network function is required for communication between the VLANs?

A
A router or Layer 3 switch must route traffic between them.
B
The devices must be connected to the same physical switch.
C
Both ports must be configured as access ports in their respective VLANs.
D
The switch must assign both devices to the same VLAN.

switchport mode access 20
B
vlan access 20
C
switchport vlan 20
D
switchport access vlan 20

From global configuration, complete the commands to create VLAN 30 and name it OPERATIONS:

Switch(config)# 
Switch(config-vlan)#

Fill in the blank

1 point

An administrator has just named VLAN 30 and wants to create VLAN 40 next. Complete the command that returns to global configuration so the following command is valid:

Switch(config)# vlan 30
Switch(config-vlan)# name OPERATIONS
Switch(config-vlan)# 
Switch(config)# vlan 40
