What does the "Tier-1" router in NSX-T provide?

The "Tier-1" router in NSX-T primarily provides East-West traffic routing for workloads. This means that it is designed to manage the routing of traffic between virtual machines (VMs) within the same data center or over different segments of the same virtual network. The Tier-1 router supports communication between different tenant networks and workloads, facilitating a flexible and efficient zoning of network resources.

This routing architecture is crucial for micro-segmentation and enables services such as load balancing, NAT (Network Address Translation), and providing gateway services. By managing East-West traffic, the Tier-1 router plays a vital role in the overlay networking model of NSX-T, allowing for isolated and secure communication between VMs without the need for physical switches.

In contrast, options that suggest functionalities like North-South traffic management, high availability, or data encryption are not correct in this context. North-South traffic typically refers to data entering or exiting the data center, which is handled by the Tier-0 router in conjunction with the Tier-1 router for the necessary path to external networks. High availability and data encryption are important features in networking but are not specific roles of the Tier-1 router itself. Overall, understanding the specific purpose of the Tier-1 router
