To avoid IP address conflicts and ensure there are no configuration issues when reusing an existing AWS subnet, the administrator should take the following actions:

aCLI > net.add_to_ip_blacklist 10.79.4.200 aCLI > net.add_to_ip_blacklist 10.79.4.201 (Answer A):

This command adds the specified IP addresses to the blacklist, preventing AHV IPAM from assigning these addresses to any VMs. This ensures that the existing EC2 instances with IPs 10.79.4.200 and 10.79.4.201 are not allocated to other VMs in the NC2 cluster.

Configure the AHV IPAM to use DHCP range 10.79.4.2 -10.79.4.253 (Answer D):

By configuring the AHV IPAM to use a specific DHCP range, you ensure that the IP addresses assigned to the EC2 instances (10.79.4.200 and 10.79.4.201) are not included in the DHCP pool. This prevents IP address conflicts within the subnet.

When planning to leverage NC2 on AWS for an elastic DR scenario where the initial cluster is using 13en.metal, the following additional node types are supported for cluster expansion:

I3.metal: These instances provide high IOPS and low latency with NVMe SSDs, making them suitable for storage-intensive applications.

i4i.metal: These instances offer higher performance with AWS Nitro SSDs, improved network bandwidth, and better compute performance compared to the I3.metal instances.

To manually hibernate an NC2 on AWS cluster, the administrator can use the following methods:

Select the cluster under NC2 console and Select Hibernate/Resume on the cluster sur page: Navigate to the specific cluster in the NC2 console and use the provided Hibernate/Resume option.

Log into NC2 console, find the cluster name and select Hibernate/Resume from the ellipses: Access the NC2 console, locate the cluster name, and select the Hibernate/Resume option from the ellipses (three dots) menu.

These options allow for the manual control of the cluster's hibernation state directly within the NC2 console interface.

AWS Direct Connect allows companies to create private, dedicated connections between their data centers and AWS. This bypasses the internet and provides a more reliable and faster network connection directly to AWS services, including S3.

The requirement for two private subnets in the NC2 cluster configuration workflow serves the same purposes:

One subnet is designated for user VMs, ensuring user workloads are separated from management operations.

The other subnet is designated for cluster management, maintaining the integrity and security of management processes and internal communications.

Given the company's large spend commitments as part of an AWS Enterprise Discount Program (EDP) totaling $15 million, purchasing Nutanix licenses through the AWS Marketplace ensures that the costs contribute to the EDP commitment.

This approach integrates the Nutanix license costs into the overall AWS spend, thereby maximizing the benefits of the EDP.

Purchasing directly from Nutanix or leveraging existing licenses might not count towards the AWS EDP commitment, and trial licenses are typically for evaluation purposes and do not contribute to the committed spend.

References:Refer to the Nutanix and AWS documentation on licensing and marketplace purchases, and EDP program details.

The maximum number of nodes supported in an NC2 cluster on AWS is 24 nodes. This limit ensures optimal performance and manageability within the AWS infrastructure while leveraging the benefits of the Nutanix architecture.

A valid CIDR range: A CIDR (Classless Inter-Domain Routing) range is necessary for creating the subnets within the VPC. This range defines the IP address space for the cluster and its components.

A my.nutanix.com account: This account is required to access Nutanix services, including the NC2 console, manage licenses, and perform other administrative tasks.

AWS Direct Connect and an on-premises Prism Central environment are not prerequisites for deploying an NC2 on AWS cluster. While Direct Connect can be used for enhanced network performance and connectivity, it is not a requirement for deployment. Similarly, having an on-premises Prism Central environment is not mandatory for NC2 deployment on AWS.

References:Refer to the Nutanix documentation on NC2 prerequisites and setup guides, and AWS documentation on VPC and subnet creation.
