What is the primary function of a VLAN in network segmentation?

To create separate broadcast domains within a single physical switch

To replace the need for IP addressing in a network

To connect multiple physical sites over the internet securely

To provide encryption for data transmitted between switches

A network team is implementing VLAN segmentation for a multi-tenant office building. Each tenant should not be able to see other tenants' broadcast traffic. What is the most important configuration step to ensure this isolation?

Assign each tenant to a unique VLAN and do not route between the VLANs unless explicitly required.

Use the same VLAN for all tenants but apply different subnets to each tenant.

Place all tenants on the same subnet but use ACLs to block broadcast traffic.

Configure all switches to use the same VLAN trunking protocol to ensure consistency.

What is the role of a firewall in network segmentation?

To assign IP addresses to devices in different segments

To provide wireless connectivity to segmented networks

To control and filter traffic between network segments based on security policies

To replace the need for VLANs and subnets

How do VLANs improve network security?

By assigning a unique IP address to every device on the network

By automatically blocking all inbound traffic from the internet

By encrypting all traffic between hosts in the same VLAN

By preventing any communication between different VLANs without a router or firewall
