The exhibit shows two cloud accounts, one for Azure and one for AWS, with their statuses indicated. The AWS cloud account status is marked as "U" (which likely stands for "Unavailable" or "Unreachable"). This indicates that the AWS cloud account configuration is not properly connected or accessible.

Status Check:

The AWS cloud account is marked with an "U" status, meaning it is not active or accessible.

This status prevents the creation of an NC2 cluster because the necessary cloud resources cannot be allocated or managed without a proper connection.

Action:

The best course of action is to create a new cloud account in the organization. This involves setting up the cloud account details correctly and ensuring it is properly configured to communicate with Nutanix and AWS.

Steps to Create a New Cloud Account:

Log in to the Nutanix console.

Navigate to the "Organizations" section.

Select "Add Cloud Account" and provide the required AWS credentials and permissions.

Ensure the new cloud account is active and correctly configured.

For the NC2 cluster deployed in the North Virginia region (us-east-id), consuming IPs from the 10.78.2.0/24 range, the subnets configured within the same CIDR range of 10.78.0.0/16 will be recognized.

The subnetDR01 (10.78.2.0/24)is directly within the range of the deployed cluster.

The subnetL2stretch (10.19.101.0/24)is also configured in the NC2 AWS VPC, although not in the immediate range of the cluster, it may show up due to broader network configurations for stretched L2 operations.

SubnetsVDI (10.78.130.0/22)andDR02 (10.79.120.0/24), although part of the same VPC, are not directly within the immediate CIDR range or may not be recognized in this specific configuration scenario.

References:Refer to the Nutanix documentation on NC2 AWS VPC subnet configurations and Prism Element settings for detailed guidelines on network visibility and configuration.

The Nutanix Create Cluster wizard may not support selecting subnets that have both IPv4 and IPv6 CIDR blocks due to compatibility or configuration constraints.

When a subnet with both CIDR blocks is present, it can cause issues in the selection process during cluster creation, as the system might not be able to properly handle or recognize the dual-stack configuration.

Ensuring that the management subnet has only an IPv4 CIDR block, without an IPv6 CIDR block, could resolve this issue and allow for successful selection in the cluster creation wizard.

References:Refer to the Nutanix and AWS documentation on subnet configuration and requirements for NC2 cluster deployments, specifically addressing IPv4 and IPv6 compatibility and constraints.

In Nutanix Cloud Integration with AWS, specifically version 6.7, the role that allows full access to clusters created within an organization is the Organization Administrator.

The Organization Administrator role has the highest level of privileges within an organization, enabling the user to manage all aspects of the clusters, including creation, modification, and deletion.

This role is designed to oversee and control the entire organization's resources, ensuring comprehensive management capabilities over all clusters and associated resources.

References:Refer to the Nutanix documentation on roles and permissions for NC2 on AWS for further details.

To resolve the IP conflict issue when an EC2 instance is powered on in a subnet also used by Nutanix NC2, the administrator should block or exclude the IP address used by the NC2 VM from being assigned to EC2 instances. This can be done by configuring the IP address management (IPAM) settings to ensure that the specific IP addresses allocated to the NC2 VMs are not used by EC2 instances, preventing IP conflicts and ensuring smooth operation of both environments.

Nutanix Best Practices for AOS Support

When setting up a landing zone for Nutanix clusters on AWS, having only private subnets for cluster management and user VMs is not sufficient for full cluster functionality. Nutanix clusters often need to communicate with the internet for updates, patches, and other cloud services.

VPC Configuration:

The VPC already has two private subnets (one for cluster management and one for user VMs).

Additional Requirements:

To access public services like S3 or for the cluster nodes to reach Nutanix services for updates, a public subnet is essential.

Why Public Subnet for Internet Access?:

A public subnet allows resources within it to communicate directly with the internet, which is necessary for accessing Nutanix's update servers, applying patches, and other maintenance tasks.

This subnet typically includes an internet gateway, enabling instances in the public subnet to receive and send traffic directly to the internet.

Nutanix Networking and Subnet Configuration Guidelines

Upon creation, each node within an AWS NC2 cluster has3 Amazon Elastic Block Store (EBS)volumes attached.

These volumes are used for different purposes, such as operating system storage, Nutanix services, and user data storage.

The number of EBS volumes is designed to ensure adequate storage performance and capacity for the NC2 cluster's operations and workload demands.

References:Refer to the Nutanix documentation on NC2 cluster setup and AWS EBS volume configurations to confirm the details on the number and purpose of EBS volumes attached to each node.

To control network traffic at the individual User VM (UVM) subnet level, creating a custom security group is the appropriate action. This approach allows for fine-grained control over inbound and outbound traffic rules that can be applied to specific subnets or individual instances within those subnets.

Custom Security Group:

Custom security groups enable administrators to define specific traffic rules tailored to the needs of individual subnets or VMs. This includes specifying allowed IP ranges, ports, and protocols.

By applying these custom security groups to the UVMs, the organization can control access and enhance security according to their policies and requirements.

Steps to Create a Custom Security Group:

Navigate to the AWS Management Console and go to the VPC service.

Select "Security Groups" under the "Security" section.

Click on "Create Security Group" and define the name, description, and VPC.

Add inbound and outbound rules according to the desired traffic control policies.

Attach the custom security group to the UVMs or subnets in question.

Nutanix Best Practices for Security Groups

To determine which subnets would be able to receive inbound traffic from AWS instances on a 10.0.0.0/22 network segment, we need to look at the configured subnets and their CIDR ranges, as well as the custom network security group's inbound rules.

Available CIDR ranges in VPC:

70.73.0.0/16

10.79.107.0/24

10.0.0.0/22

Configured Subnets in NC2 AWS VPC:

VDI: 10.78.130.0/22

SQL: 10.78.3.0/24

Server01: 10.78.2.0/24

Server02: 10.79.120.0/24

Tier01: 10.19.101.0/24

Custom Network Security Group Inbound Rule:

Allows all inbound traffic from 10.0.0.0/22.

Given that the custom network security group is allowing inbound traffic from the 10.0.0.0/22 network, we need to identify which of the configured subnets fall within this allowed range.

Analysis:

The subnets 10.78.130.0/22, 10.78.3.0/24, 10.78.2.0/24, 10.79.120.0/24, and 10.19.101.0/24 do not overlap with 10.0.0.0/22. Therefore, none of these subnets would naturally fall within the 10.0.0.0/22 range directly.

However, since the question is about receiving inbound trafficfromthe 10.0.0.0/22 network and considering security group rules, all subnets mentioned can technically receive traffic if the inbound rules are configured correctly, but since we are strictly asked about the configuration from the image and the overlap in the ranges:

Server01 (10.78.2.0/24)andTier01 (10.19.101.0/24)will receive traffic because their CIDR ranges do not conflict with the 10.0.0.0/22 range, thus allowing traffic without additional restrictions.

To deploy an NC2 cluster using an existing AWS network, the NAT Gateway should be placed in a public subnet. A public subnet is one that has a route to an Internet Gateway, allowing the NAT Gateway to provide outbound internet access for resources in private subnets. The NAT Gateway is used to enable instances in private subnets to access the internet while keeping them secure by not exposing them directly to the public internet.

Ensure the specialist is assigned the RBAC role with proper permissions (Answer A):

Role-Based Access Control (RBAC) ensures that the specialist has the necessary permissions to troubleshoot and manage the NC2 environment. This avoids unnecessary privilege escalations and maintains security.

Confirm the Support Authorization on the organization is set to Full Access (Answer C):

Setting the Support Authorization to Full Access allows the Nutanix support specialist to have the required access to investigate and resolve issues in the environment. This is essential for effective troubleshooting.

To create a CloudFormation stack, the AWSCloudFormationFullAccess role is required.

This role grants the necessary permissions to create, update, and delete CloudFormation stacks, which are essential for deploying and managing AWS infrastructure using CloudFormation templates.

CloudFormation stacks are often used to automate the deployment of complex infrastructures, including those required for NC2 on AWS.

Proper permissions ensure that the deployment process is seamless and adheres to the security and operational policies of the organization.

References:Refer to the AWS IAM documentation for details on the AWSCloudFormationFullAccess role and Nutanix documentation on prerequisites for deploying NC2 on AWS.

When creating user VM subnets for multiple NC2 clusters in AWS, the best approach is to create guest-VM subnets for each cluster. This ensures that each cluster has its own dedicated subnets, which simplifies network management and avoids potential IP conflicts.

Advantages of Dedicated Subnets:

Isolation: Each cluster operates in its own subnet, providing better isolation and security.

Management: Easier to manage and troubleshoot network issues when each cluster has its own subnets.

Scalability: More scalable as each subnet can be managed and expanded independently.

Steps to Create Guest-VM Subnets:

Identify the IP range for each subnet.

In the AWS VPC console, create a new subnet for each cluster using the identified IP ranges.

Associate the new subnets with the respective clusters during or after the cluster deployment process.

Why Not Shared Subnets:

Shared subnetscould lead to IP conflicts and make network management more complex, especially as the number of clusters grows.

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.

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.
