An NSX administrator has deployed a single NSX Manager node and will be adding two additional nodes to form a 3-node NSX Management Cluster for a production environment. The administrator will deploy these two additional nodes and Cluster VIP using the NSX UI. What two are the prerequisites for this configuration? (Choose two.)

To deploy additional NSX Manager nodes and form a high-availability cluster with a Virtual IP (VIP) using the NSX UI, two key prerequisites must be met. First, a compute manager (vCenter Server) must be registered with the initial NSX Manager. This is because the UI-driven process orchestrates the deployment of the new NSX Manager virtual appliances directly onto the vSphere infrastructure, which requires API access to vCenter. Second, all NSX Manager nodes that will participate in the cluster must reside on the same Layer 2 network segment (subnet). This is a mandatory requirement for the cluster's VIP to function correctly and fail over between the nodes.

A. The cluster configuration can be completed using either the UI or the API. The question specifically states the administrator will use the UI, which is a valid method.
C. All nodes must be in the same subnet for the VIP to work. Placing them in separate subnets would prevent the VIP from being reachable if the active node fails.
E. The NSX Manager is a pre-packaged Linux-based virtual appliance (Photon OS), not an application that is installed on a Windows Server.

1. VMware NSX-T Data Center Installation Guide: In the section "Add an NSX Manager Node

" the prerequisites state: "Add a vCenter Server as a compute manager in NSX Manager. See Add a Compute Manager." This directly supports the requirement for a configured compute manager.

2. VMware NSX-T Data Center Installation Guide: In the section "NSX Manager VM and Host Requirements

" under networking considerations

it is specified: "All NSX Manager nodes in a cluster must be in the same subnet to use a cluster VIP." This confirms the same-subnet requirement.

3. VMware NSX-T Data Center Administration Guide: The section on "NSX Manager Cluster" details the architecture and states

"To ensure manager cluster stability

the NSX Manager nodes must be deployed on hosts that are in separate vSphere clusters." While this refers to host placement for anti-affinity

it implicitly relies on the underlying networking prerequisite that the nodes can communicate on the same management subnet to form the cluster and share a VIP.
