An administrator wants to ensure that enough available bandwidth exits for workloads running in an NC2 on Azure cluster environment. What is the highest number of Flew Gateway VMs that can be deployed within this environment?

Nutanix Flow Networking allows for the deployment of Flow Gateway VMs to provide centralized IP address management and policy-based routing between VLANs and the external network. To ensure high availability and scale bandwidth for workloads, the NC2 on Azure environment supports deploying a maximum of six Flow Gateway VMs. This deployment model allows for load balancing and redundancy, ensuring sufficient network throughput and resilience for the applications running on the Nutanix cluster.

A. A single Flow Gateway VM would be a single point of failure and would not provide sufficient bandwidth or high availability for a production cluster.
B. While three VMs could provide redundancy, the architecture supports scaling up to six for greater throughput and resilience.
C. Four is a possible number of deployed VMs, but it is not the maximum supported limit for scaling out.

1. Nutanix Flow Networking Guide v4.1, Chapter: "Gateway Virtual Machine for Centralized IPAM", Section: "Gateway VM Scale and High Availability". The guide specifies the deployment limits and high availability configurations, noting the maximum number of supported instances.

2. Nutanix Cloud Clusters on Azure Deployment and User Guide v6.7, Chapter: "NC2 on Azure Networking", Section: "Flow Gateway Deployment". This section details the architecture and states that up to six Flow Gateway VMs can be deployed for scale-out bandwidth and HA.
