What is a logical network segment created by assigning VLAN IDs to ports on a managed switch?

• A. IP
• B. security zones
• C. VLAN
• D. on-premises network

Answer: (C)

A VLAN is a logical network segment created by assigning VLAN IDs to ports on a managed switch. By placing ports into the same VLAN, you create a distinct broadcast domain at Layer 2, so devices on that VLAN can communicate directly with each other while broadcasts are contained within that segment. If devices on different VLANs need to talk, inter-VLAN routing is required via a router or L3 switch. VLAN tagging (802.1Q) lets traffic from multiple VLANs traverse trunk links between switches while preserving each VLAN’s identity. This concept focuses on isolating and organizing network traffic within the same physical infrastructure, which is not about IP addressing, security zones, or a generic on-premises network.
