Your question is Troubleshoot Inter-Data Center Latency. 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).
How would you troubleshoot a high-latency connection between two geographically dispersed data centers?
Explain a structured investigation using Azure Network Watcher Connection Monitor, ping, traceroute or tracert, TCP measurements, and packet captures. Cover how you would distinguish propagation delay from congestion, packet loss, routing problems, MTU issues, DNS delay, and endpoint or application bottlenecks. Keep the answer platform-focused on Microsoft Azure, Windows Server, and Linux networking tools.
