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.
