To achieve routing between all segments in a network that consists of three tiers using NSX-T, the administrator can use gateways. Specifically, the use of Tier-0 and Tier-1 Gateways enables routing between different segments. The segments can be connected to a Tier-1 Gateway, which in turn can be connected to a Tier-0 Gateway to provide routing to external networks.

The Management Plane in the NSX-T Data Center Architecture is responsible for creating and deleting network objects. This plane provides an interface for administrators to manage the network, including configuration and orchestration of network services.

vSphere vMotion allows an administrator to upgrade hardware while keeping virtual machines online. vMotion enables the live migration of running VMs from one physical server to another with zero downtime, continuous service availability, and complete transaction integrity.

Two benefits of virtual networking are:

Reduced provisioning time: Virtual networking allows for faster deployment and configuration of network services, as it abstracts the physical hardware and automates many of the processes involved in network setup.

Increased network visibility: Virtual networking solutions, such as those provided by VMware NSX, offer enhanced visibility into network traffic, making it easier to monitor, analyze, and manage network performance and security.

NSX managed compute endpoints are called Transport Nodes. A transport node is a host or a NSX Edge that has NSX modules installed and is registered with the NSX Manager.

The key value for the VMware approach to a software-defined data center (SDDC) is a vendor-agnostic platform. VMware's SDDC architecture supports a wide range of hardware, software, and cloud environments, providing flexibility and interoperability regardless of the underlying vendor.

To enable vSphere High Availability (HA), ESXi hosts need access to shared data storage. Shared storage is critical for HA as it allows virtual machines to be restarted on other hosts within the cluster in the event of a host failure. The shared storage ensures that the virtual machine files are accessible to any host in the HA cluster, facilitating seamless failover.

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.
