B. It is a module deployed in all transport nodes that provides L2 functionality. D. ESXi hosts support both N-VDS and VDS.

N-VDS (NSX Virtual Distributed Switch) and VDS (vSphere Distributed Switch) are both network switch constructs used in NSX-T Data Center. The N-VDS provides Layer 2 (L2) functionality and is deployed on all transport nodes to handle network traffic. ESXi hosts support both N-VDS and VDS, allowing for flexible network configurations.

In the NSX-T Data Center Architecture, the three different types of planes available are:

Control Plane: This plane is responsible for managing the communication between the management plane and the data plane. It handles the configuration and propagation of network state.

Management Plane: This plane provides the interface for the user to manage the network. It includes the NSX Manager and other management tools.

Data Plane: This plane is responsible for handling the actual data packet processing and forwarding.

The Network Plane, Routing Plane, and Security Plane are not part of the defined planes in NSX-T architecture terminology.

In the NSX-T Data Center Architecture, the Data Plane components include:

B. Edge Node: These nodes are responsible for providing services such as routing, NAT, and load balancing. Edge nodes are critical for north-south traffic and can also handle east-west traffic.

D. Hypervisor: The hypervisor is part of the data plane as it hosts the NSX-T virtual switches (N-VDS or VDS) that handle network traffic for VMs.

To optimize East/West traffic while maintaining an overlay-based Layer 3 communication, the customer can use Tier-1 Gateways in NSX-T Data Center. Tier-1 Gateways facilitate efficient internal routing and traffic management within the data center, optimizing East/West traffic.
