Which routing component must be deployed to provide north-south connectivity for VMs in a multi-tier routing topology?

In a multi-tier routing topology within VMware NSX-T, the Tier-0 Gateway plays a crucial role in providing north-south connectivity. This gateway is responsible for handling the external connectivity of the virtualized environment, allowing for communication between the virtual machines (VMs) hosted in the data center and external networks, such as the internet or other data centers.

The Tier-0 Gateway serves as the primary point of egress and ingress for traffic entering or leaving the NSX-T environment. It is designed to manage high throughput and offers advanced routing features, which are essential for ensuring effective communication across various network segments.

This gateway is aligned with the concept of a multi-tier architecture, where different tiers of gateways (Tier-0 and Tier-1) serve specific purposes. The Tier-1 Gateway is used for East-West traffic within the NSX-T environment, linking different segments and providing services like load balancing and DHCP, but it does not handle the connectivity to external networks. The Edge Services Gateway is also a component used for specific edge services like NAT and firewalling but is dependent on the Tier-0 to provide external routing capabilities.

Ultimately, the Tier-0 Gateway acts as the bridge between the virtualized network and the external world, making it
