vCenter Server is required to deploy NSX Edge virtual machines. The NSX Edge provides routing, firewall, VPN, load balancing, and other network services. The deployment and management of NSX Edge virtual machines are handled through the vSphere Web Client, which necessitates the use of vCenter Server.

The component that provides virtual switching capabilities in NSX-T Data Center is the NVDS (NSX Virtual Distributed Switch). NVDS allows for the creation and management of virtual networks within the NSX-T environment, supporting advanced network functions like distributed switching, routing, and firewalling.

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.

To access the NSX Manager, you use the NSX UI with a supported browser. The NSX Manager provides a web-based user interface for managing and configuring the NSX environment. This UI is accessible via a web browser and does not require a dedicated fat client or telnet access. The vSphere Client can also access NSX Manager, but the primary method is through the NSX UI.

The Data Plane in the NSX-T Data Center architecture performs the network traffic forwarding. The Data Plane is responsible for the actual handling of packets, including switching, routing, and firewall enforcement. It operates based on the instructions from the Control Plane.

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.

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).
