Nutanix Certified Professional - Cloud Integration - AWS v6.7 NCP-CI-AWS Exam Practice Test

Answer : A

Amazon CloudWatch is the service that enables the monitoring of key metrics on various AWS services, including EC2, EBS, and VPC, for NC2 cluster deployments.

Amazon CloudWatch:

Amazon CloudWatch provides monitoring for AWS cloud resources and applications. It collects and tracks metrics, collects and monitors log files, and sets alarms.

Specifically, for NC2 deployments, CloudWatch can be used to monitor key metrics such as CPU utilization, disk I/O, network I/O for EC2 instances, EBS volume performance, and VPC network traffic.

Features:

Metrics Monitoring: Collects and visualizes operational data in the form of metrics, including utilization, performance, and health.

Logs Monitoring: Collects log data, monitors it in real-time, and triggers alarms based on predefined thresholds.

Alarms: Notifies when operational performance thresholds are breached.

Integration with NC2:

By setting up CloudWatch, administrators can ensure they have visibility into the performance and health of their Nutanix clusters on AWS, aiding in proactive management and troubleshooting.

AWS Monitoring Best Practices

Answer : C, D

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.

For AOS software support related to NC2, the appropriate entity to contact is Nutanix. Nutanix provides comprehensive support for their software, including the Acropolis Operating System (AOS) used in NC2 deployments.

Support Scope:

Nutanix offers support for the deployment, configuration, and management of NC2 clusters, including any issues related to AOS software.

This includes troubleshooting, updates, and technical assistance.

Why Not Other Options:

Internal IT Operations team: Typically handles internal issues but does not have the specialized knowledge or resources for AOS software support.

Partner: May provide support but would ultimately escalate issues to Nutanix for software-specific concerns.

Public Cloud Vendor: Manages infrastructure-related issues but does not provide support for Nutanix AOS software.

Answer : C

To create a cluster in Nutanix Cloud Integration with AWS, the role needed is Cluster Super Admin.

The Cluster Super Admin role provides the highest level of privileges required to perform critical operations such as creating, managing, and deleting clusters.

This role is essential for overseeing the cluster setup and configuration processes, ensuring the user has full control over the cluster lifecycle.

Reference: Refer to the Nutanix documentation on roles and permissions for NC2 on AWS for further details on the capabilities and required permissions for cluster creation.

Answer : B

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.

AWS Networking Best Practices

Nutanix Networking and Subnet Configuration Guidelines

Answer : A

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.
