Nutanix NCP-CI-AWS Dumps

When deploying a new NC2 cluster, the AWS Directory Service must be able to resolve the addressgateway-external-api.cloud.nutanix.com.

This external API gateway is critical for the NC2 cluster to communicate with Nutanix services for operations such as management, updates, and licensing.

Ensuring that this address can be resolved allows the cluster to interact properly with the Nutanix cloud infrastructure and services.

References:Refer to the Nutanix documentation on network and DNS requirements for NC2 deployments, specifically the addresses that need to be resolvable for proper functionality.

To ensure that NC2 VMs can access AWS resources without traversing the internet, the administrator can use AWS VPC Peering and Interface Endpoints. Both methods ensure that traffic stays within the AWS network, maintaining security and efficiency.

Interface Endpoint:

Interface Endpoints allow you to privately connect your VPC to supported AWS services. They use AWS PrivateLink to route traffic directly to services within the AWS network, bypassing the public internet.

Steps:

Create an interface endpoint for the required service in the AWS VPC console.

Ensure the security groups and route tables are configured to allow traffic to the interface endpoint.

VPC Peering:

VPC Peering allows the routing of traffic between VPCs using private IP addresses, without the need for internet gateways, NAT devices, or VPN connections.

Steps:

Create a VPC peering connection between the VPCs.

Update the route tables to direct traffic between the peered VPCs.

Ensure security group rules allow the necessary traffic between VPCs.

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.

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.

When selecting the NC2 subscription plan from the Nutanix Billing portal, the available options include:

Pay-as-you-Go (PayG): A flexible payment option where users are billed based on their actual usage, providing cost efficiency for variable workloads.

Bring your own License (BYOL): Allows users to utilize existing Nutanix licenses they have purchased, offering a cost-effective way to leverage existing investments in Nutanix software.

References:Refer to the Nutanix billing and subscription documentation for detailed descriptions of subscription plans and their benefits.

When a node is marked as "Condemned," it indicates that the system has determined that the node is no longer reliable for operations. As part of the automated recovery and protection process, the following action is typically taken:

The node has a power reset sent to it (Answer A):

In most cases, a condemned node undergoes a power reset as an initial recovery attempt. This action attempts to reboot the node to bring it back to a healthy state. If the reset fails,further manual or automated steps may be required to address the hardware or software issue.

To ensure that alert emails are sent properly from Prism Central within an NC2 environment, configuring an SMTP server in the Prism Central settings is required. The SMTP server facilitates the sending of email notifications for alerts and other communications.

SMTP Configuration:

Prism Central requires an SMTP server to send email alerts. This involves specifying the SMTP server address, port, and authentication details if needed.

The configuration must include the email address from which the alerts will be sent and the recipient addresses.

Steps to Configure SMTP Server in Prism Central:

Log in to Prism Central.

Navigate to the "Settings" menu.

Select "Email Server" under the "Alerts" section.

Enter the SMTP server details, including the server address, port, and authentication credentials.

Test the configuration to ensure emails are sent correctly.

AWS Monitoring Best Practices

To protect workloads on an NC2 cluster on AWS, deploying strategies that ensure high availability and disaster recovery are essential. The two valid options are:

Create a Second NC2 Cluster in a Different Availability Zone:

High Availability: Deploying a second NC2 cluster in a different availability zone ensures that workloads can be quickly recovered in case of an availability zone failure.

Disaster Recovery: This setup enables asynchronous replication between clusters, providing a robust disaster recovery solution.

Use an Existing On-Prem Nutanix Cluster as a Disaster Recovery Target:

Hybrid DR: Leveraging an existing on-premises Nutanix cluster for disaster recovery provides a cost-effective and efficient DR solution.

Replication: Set up replication policies to ensure data is consistently copied from the NC2 cluster on AWS to the on-premises cluster.

Why Not Other Options:

One-node cluster in another availability zone: Not a valid DR solution as a single-node cluster cannot provide the required resilience and high availability.

Deploy a cluster across two availability zones: While this can enhance availability, it is not a typical approach for Nutanix clusters which are designed to operate within a single availability zone for simplicity and performance reasons.

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.

Gateway Endpoint:

A Gateway Endpoint in AWS allows you to connect to supported AWS services privately without going through the public internet. This setup provides secure and efficient connectivity directly from the corporate VPC to the required AWS services.

Gateway Endpoints support services such as Amazon S3 and DynamoDB and are ideal for scenarios where private connectivity to these services is needed.

References:Refer to the AWS documentation on VPC endpoints, specifically Gateway Endpoints, and the Nutanix documentation on configuring private connectivity for NC2 deployments.

To support Nutanix's native Local Key Manager (LKM) for data encryption in a cost-effective manner, a minimum of three nodes is required. This ensures that there is enough redundancy and reliability for the encryption services to function properly, complying with best practices for distributed key management.

Nutanix Cloud Clusters on AWS Administration

To add an AWS account to the NC2 console, an AWS IAM user needs to be configured with the appropriate permissions to manage the EC2 resources. The required permission for the IAM user includes full access to manage EC2 instances, volumes, and related resources.

AmazonEC2FullAccess:

This permission grants full access to all EC2 resources, including the ability to create, modify, and delete instances, volumes, security groups, and more.

Essential for NC2 operations to manage the lifecycle of EC2 instances and associated components within the AWS environment.

Why Not Other Permissions:

IAMFullAccess: Grants full access to IAM resources but not specifically needed for EC2 operations.

IAMReadOnlyAccess: Only provides read access to IAM resources, insufficient for managing EC2 instances.

AmazonEC2ReadOnlyAccess: Provides read-only access to EC2 resources, insufficient for creating or modifying instances and other resources.

When configuring a syslog server in the Prism Central Admin Center for Nutanix, one of the available log modules is Acropolis.

The Acropolis module logs system events related to the Nutanix Acropolis operating system, which is critical for monitoring and auditing system activities and performance.

Configuring syslog with the Acropolis module ensures that important events and issues related to the Acropolis environment are captured and can be forwarded to an external syslog server for centralized logging and analysis.

References:Refer to the Nutanix documentation on Prism Central and syslog configuration for the full list of available log modules and detailed steps for configuration.

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.
