Which technique does NSX-T utilize to allow communication between different security segments?

NSX-T utilizes East-West traffic routing to facilitate communication between different security segments. This technique is crucial for managing traffic within the data center or cloud environment, as it enables seamless communication between virtual machines (VMs) and applications that may reside in different parts of the network without needing to traverse the traditional North-South routing pathways.

East-West routing emphasizes intra-data center traffic, allowing for the efficient flow of data between segments that may have varied security policies. By leveraging this approach, NSX-T is able to maintain consistent security postures across segments, enabling micro-segmentation and granular control over workloads. This capability is a key aspect of NSX-T's design, empowering organizations to enhance security while supporting high-performance applications and services.

In contrast, other options like static routing or dynamic routing primarily focus on managing traffic paths based on predefined or adaptive criteria, which are not specifically aimed at intra-segment communication like East-West routing is. VPN tunneling is also more relevant for secure communication over external networks rather than managing traffic within a data center's security segments. Thus, East-West traffic routing stands out as the most effective mechanism within the unique architecture of NSX-T.
