NSX Cloud is the VMware product designed to manage and extend data center networks into VMware Cloud on AWS and Microsoft Azure Cloud. NSX Cloud provides consistent networking and security for applications running in both private data centers and public clouds, ensuring seamless connectivity and uniform policy enforcement across hybrid environments.

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.

vSphere High Availability (HA) brings a virtual machine back online on another ESXi host when a virtual machine fails on an ESXi host. HA monitors ESXi hosts and virtual machines to detect hardware and guest operating system failures and restarts VMs on other available hosts in the cluster.

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 create NSX-T objects from code, an administrator should use the REST API. The NSX-T REST API allows administrators to automate and manage NSX-T resources programmatically. It provides comprehensive capabilities for creating, configuring, and managing network objects, such as segments, gateways, and firewall rules, directly from code.

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 ensure that the servers of a 3-tier application can communicate with each other and users can access the application from the external network using a multi-tier deployment, the administrator needs to:

C. Connect the three segments to a Tier-1 Gateway from the NSX UI: This ensures internal routing between the segments.

D. Connect the Tier-1 Gateway to the Tier-0 Gateway from the NSX UI: This enables routing from the internal network to the external network.

To encrypt file transfers between two sites that do not have the same subnet, the IPSEC VPN feature in NSX-T can be used. IPSEC VPNs provide secure communication over IP networks by encrypting the data transferred between the two sites, ensuring data confidentiality and integrity.

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.

To secure two virtual machines attached to the same segment, the customer can configure a distributed firewall rule using NSX Data Center. The NSX Distributed Firewall (DFW) allows for micro-segmentation, providing granular security controls and policies that can be applied to individual virtual machines, even if they are on the same network segment.

The three types of transport nodes in NSX-T are:

A. NSX Edges: These are nodes that provide edge services and north-south routing.

D. Bare-metal servers: These servers can be configured as transport nodes to extend NSX-T networking and security to physical workloads.

F. Hypervisors: These nodes run virtualized workloads and host NSX-T virtual switches, enabling NSX-T to manage network traffic within the virtual 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).
