Which statement accurately describes the relationship between VLANs and broadcast domains?

• A. Each VLAN forms its own broadcast domain
• B. One VLAN can share a broadcast domain with others
• C. VLANs have no effect on broadcast domains
• D. VLANs convert broadcast domains into unicast streams

Answer: (A)

VLANs segment broadcast domains. A VLAN creates a logical grouping where broadcast frames are confined to devices in that same VLAN, even if those devices share the same physical switch with devices in other VLANs. Devices in different VLANs don’t see each other’s broadcasts unless inter-VLAN routing is provided by a router or Layer 3 switch. So, each VLAN has its own separate broadcast domain, which is why the statement about every VLAN forming its own broadcast domain is correct. The other ideas don’t fit: sharing a broadcast domain across multiple VLANs would defeat the purpose of VLANs, and VLANs don’t turn broadcasts into unicast streams within the VLAN.
