Your question is Role of VLANs for Security and Performance. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Explain the role of VLANs and how they enhance network security and performance.
Cover how VLANs divide a Layer 2 network into separate broadcast domains, the difference between access ports and 802.1Q trunk ports, and how inter-VLAN communication is implemented. Include one practical example showing how segmentation, broadcast containment, and ACLs affect security and performance.
