Nutanix NCP-CI-AWS Dumps

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.

To enable inbound internet access to Virtual Servers in an NC2 cluster on AWS for the HTTPS protocol, the administrator should use an AWS Network Load Balancer (NLB).

Configure the NLB listener to listen on TCP port 443, which is the standard port for HTTPS traffic.

Create a target group in AWS, and register the servers (Virtual Servers in the NC2 cluster) as targets within this group.

Ensure the NLB is properly configured with an Elastic IP (EIP) if required, to provide a static IP address for the load balancer.

Verify that the security groups and network ACLs associated with the load balancer and the target group allow inbound traffic on port 443.

References:Refer to AWS documentation on Network Load Balancers and Nutanix NC2 on AWS integration guides for step-by-step instructions on setting up and configuring the necessary components for enabling HTTPS access.

To ensure that only application servers from the source subnet 10.79.1.0/24 can access the SQL databases running on the NC2 cluster in the subnet 10.78.1.0/24, the administrator can take the following actions:

Option A: Create a custom Security Group with the following rules:

Key = tag:nutanix:clusters

Key = tag:nutanix:clusters:external

and value = the clusters' UUID

Key = tag:nutanix:clusters:external

and value = 10.78.1.0/24

Option D: Create a custom Security Group with the following:

Key = nutanix:clusters

Key = nutanix:clusters:external

and value = the clusters' UUID

Key = nutanix:clusters:external

and value = 10.79.1.0/24

These actions help create security rules that restrict access to the databases only from the specified source subnet, ensuring secure and controlled access.

AWS IAM Documentation

The 192.168.5.0/24 range is often reserved for internal cluster communication within Nutanix deployments.

Using this CIDR range for other purposes could lead to network conflicts and connectivity issues, as it might interfere with the internal operations and communication channels of the Nutanix cluster.

Ensuring that the CIDR range is not overlapping with any reserved ranges is crucial for maintaining proper network connectivity and cluster functionality.

References:Refer to the Nutanix documentation on network configuration and best practices for NC2 deployments to confirm reserved IP ranges and their appropriate use.

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 alert indicates a potential issue with the VPC/Subnet settings, preventing the cluster nodes from contacting Nutanix services.

To resolve this, the administrator needs to ensure that the subnet 10.0.1.0/24, which is assigned for Bare metal hosts, has an outbound Internet connection.

This connection is necessary for the cluster nodes to communicate with external Nutanix services for updates, license validation, and other essential operations.

Verify that there are appropriate route tables and security group rules allowing outbound traffic to the Internet from the 10.0.1.0/24 subnet.

Ensure that there is either an Internet Gateway (IGW) attached to the VPC or a NAT Gateway configured if using private subnets.

References:Refer to the Nutanix documentation and AWS VPC configuration guides to ensure proper Internet connectivity and routing setups.

To ensure that every NC2 on AWS cluster deployed allows full access from the on-premises CVM subnet efficiently, the administrator should create a custom AWS Network Security Group.

Use a key value oftag:nutanix:clusters:externalfor the security group, and set the inbound allow address to the on-premises subnet.

This approach leverages AWS tags to manage security group rules dynamically and ensures that the necessary access permissions are applied automatically to all clusters with the specified tag.

This method reduces the need for manual configuration of each cluster's security group, streamlining the process for a test/dev environment where clusters are frequently created and destroyed.

References:Refer to the AWS documentation on Network Security Groups and Nutanix documentation on best practices for securing NC2 clusters.

When creating a new NC2 cluster using an existing AWS VPC infrastructure, two private subnets are needed. These subnets are used as follows:

One private subnet for user VMs, which houses the virtual machines that users interact with.

Another private subnet for cluster management, which is used for internal cluster operations and management tasks, ensuring that management traffic is isolated from user traffic for security and performance reasons.
