What is the primary effect of dividing a network into multiple VLANs?

It creates separate collision domains for each device

It increases the speed of the switch's backplane

It allows devices in different VLANs to communicate without a router

It creates separate broadcast domains at Layer 2

A switch has just been configured with a new VLAN. The administrator wants to verify that the switch is learning MAC addresses correctly. Which action should be taken?

Reboot the switch to clear the table

Generate traffic between devices in the VLAN and check the MAC address table

Check the switch's routing table

Disable the VLAN to see if the table changes

A company has two departments that should not be able to communicate directly at Layer 2, but both need to reach the same internet router. The switch supports VLANs. What should you do?

Create one VLAN and use MAC address filtering to block inter-department traffic.

Connect both departments to the same VLAN and rely on the router to filter.

Use port security to limit each port to one MAC address.

Create two VLANs and connect each department to its own VLAN; connect the router to both VLANs.

A switch receives a frame with a destination MAC address that is not in its MAC address table. How does the switch handle the frame?

It floods the frame out of all ports except the port on which it was received.

It sends the frame to the default gateway.

It drops the frame because the destination is unknown.

It sends the frame back out the port it arrived on.

A network has two departments on the same switch. The administrator wants to reduce broadcast traffic and improve security by separating the departments. Which approach is most effective?

Use a single VLAN with different IP subnets

Replace the switch with a router

Configure two VLANs and assign each department to a different VLAN

Enable MAC address filtering on the switch
