Which of the following is MOST likely to generate significant East-West traffic in a datacenter?
Click on the arrows to vote for the correct answer
A. B. C. D.B.
East-West traffic refers to network traffic that flows between servers or devices within a data center or local area network (LAN). This type of traffic is different from North-South traffic, which refers to traffic that flows between clients and servers located outside of the data center or LAN.
Out of the options given, the most likely scenario to generate significant East-West traffic in a datacenter is B. A duplication of a hosted virtual server to another physical server for redundancy.
When a hosted virtual server is duplicated to another physical server for redundancy, the two servers need to synchronize their data and configurations. This synchronization process involves a lot of data transfer between the two servers, which generates significant East-West traffic. Additionally, the duplicated server will likely be used for load balancing, which also generates East-West traffic.
Option A, a backup of a large video presentation to cloud storage for archival purposes, would generate North-South traffic because the backup is going from a server within the data center to a cloud storage service outside of the data center.
Option C, a download of navigation data to a portable device for offline access, would generate North-South traffic because the download is going from a server within the data center to a device outside of the data center.
Option D, a query from an IoT device to a cloud-hosted server for a firmware update, would also generate North-South traffic because the query is going from a device outside of the data center to a cloud-hosted server outside of the data center.
