What do cloud egress/ingress metrics measure in SD-WAN?

• A. Cloud egress/ingress metrics refer to traffic exiting or entering the cloud service, impacting performance and egress costs.
• B. Only internal LAN throughput.
• C. DNS query latency only.
• D. Color of traffic.

Answer: (A)

In SD-WAN, cloud egress and ingress metrics are about the traffic that leaves your network to reach cloud services and the traffic that returns from them. They track how much data is exchanged with cloud resources and how that traffic performs—latency, jitter, packet loss, and throughput—for both directions. This matters because cloud apps are accessed over the Internet or direct cloud connections, and cloud providers typically charge for data that leaves their networks. By monitoring these metrics, the SD-WAN can route cloud traffic along paths that deliver better performance and manage costs by avoiding costly or inefficient routes. This concept focuses on traffic to and from cloud resources, not on internal LAN throughput or DNS latency, and not on any meaningless attribute like color of traffic.
