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.

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 a software-defined data center (SDDC) solution, the following three components are virtualized:

A. Compute: Virtualizing compute resources allows for the creation and management of virtual machines, providing flexibility and efficiency in resource allocation.

C. Storage: Virtualizing storage resources involves abstracting physical storage devices into a single logical storage pool that can be managed and provisioned as needed.

F. Network: Virtualizing network resources with solutions like NSX-T allows for the creation of virtual networks that are decoupled from physical network hardware, enabling greater flexibility and scalability.

VMware NSX provides network virtualization capabilities within the virtual infrastructure layer of the Software-Defined Data Center (SDDC). NSX abstracts the network infrastructure away from the underlying hardware and provides a software-defined networking layer that allows for the creation, management, and automation of virtual networks.

To configure new L2 Broadcast Domains in NSX-T, an administrator should use Segments. Segments in NSX-T are equivalent to VLANs in traditional networking and are used to create logical L2 domains. They provide the necessary isolation and connectivity for virtual machines within the NSX-T environment.

NSX Intelligence is the solution designed to help detect lateral threat movement on east-west network traffic across multi-cloud environments. It provides real-time visibility, analytics, and security posture monitoring, making it easier to identify and mitigate threats within the network.

To provide Layer 2 connectivity between vSphere and KVM hypervisors, the customer should use NSX-T Data Center. NSX-T supports heterogeneous environments and provides networking and security services across multiple hypervisors, including vSphere and KVM.

To create GENEVE backed segments using NSX-T Data Center, a customer needs to configure an Overlay Transport Zone. GENEVE is used as the encapsulation protocol for overlay networking in NSX-T, allowing the creation of logical network segments overlaid on top of the physical network.
