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.

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.

To connect two virtual machines to an already existing segment in NSX and verify communication:

D. Use the ping command to check connectivity between VMs: This can be used to test network connectivity between the two VMs.

E. Connect the VMs to the segment from the vSphere Client: This involves editing the VM settings in the vSphere Client to attach the VMs to the desired NSX segment (Web-Segment).

The software-defined data center (SDDC) helps build the following solutions:

D. Hybrid cloud: SDDC provides the ability to integrate on-premises infrastructure with public cloud services, creating a seamless hybrid environment.

E. On-premises: SDDC principles can be applied within a private data center, allowing for automation, flexibility, and improved resource utilization.

F. Public cloud: SDDC technologies are also applicable to public cloud environments, enabling consistent infrastructure and operations across on-premises and cloud deployments.

To create a multi-tier network infrastructure in NSX-T, the customer needs to connect segments to a Tier-1 gateway and then connect the Tier-1 gateway to the Tier-0 gateway. This setup allows for the separation of internal (Tier-1) and external (Tier-0) routing.

The Management Plane in the NSX-T Data Center Architecture is responsible for create, read, update, and delete (CRUD) operations. This plane includes the NSX Manager and provides a single point for configuration and management of the NSX environment.

The firewall rule shown in the exhibit is part of a gateway firewall applied to a Tier-0 gateway (TO-GW-01). The key indicators are the "Category: LOCAL GATEWAY" and the "Applied to: TO-GW-01". The rule is set to "Drop" SSH traffic (port 22) from any source to the destinations listed (App-Servers, DB-Servers, Web-Servers).

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.

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.
