Latency and bandwidth limits on a county's DCI interconnect are forcing a redesign of stretch options. Which design principle applies?
Select an answer to reveal the explanation.
Short Explanation
The interconnect's speed, delay, and loss are the weather forecast for stretch choices. Bad SLA often pushes you toward L3 DCI; silky dark fiber can make careful L2 stretch more realistic.
Full Explanation
Interconnect characteristics—available bandwidth, latency, and loss—constrain whether Layer-2 stretch is operationally safe and whether applications will tolerate stretched adjacency. Poor SLAs often push designs toward Layer-3 DCI or selective stretch, while high-quality optical paths may allow carefully controlled L2 extension. Model selection follows interconnect reality, not overlay feature checkboxes alone.
