A township buys a Layer-2 metro Ethernet handoff between two halls and plans to stretch VLANs across it for DCI. Which characteristic should the design assume?
Select an answer to reveal the explanation.
Short Explanation
A Layer-2 metro handoff is like wiring two rooms onto the same hallway—handy for VLAN stretch, noisy for failure domains. You gain adjacency and you inherit classic L2 blast-radius risk across both halls.
Full Explanation
A Layer-2 metro interconnect can extend VLANs or bridged segments between halls, which is attractive for adjacency-sensitive applications. The same choice extends broadcast and failure domains across sites, bringing classic Layer-2 risks such as loops and BUM amplification. Professional DCI design weighs that stretch benefit against enlarged risk domains rather than treating metro L2 as risk-free.
