Nutanix NCP-CI-AWS - Nutanix Certified Professional - Cloud Integration - AWS (NCP-CI-AWS6.7) Exam

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.

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.

Route tables for cloud subnets contain incorrect route entries:

If the route tables associated with the cloud subnets contain incorrect route entries, the NC2 cluster might not be able to reach the necessary AWS services or endpoints. Correct route entries are crucial for ensuring proper communication between the NC2 cluster and the underlying AWS infrastructure.

IAM roles and policies are incorrectly configured:

Incorrectly configured IAM roles and policies can prevent NC2 from making API calls to AWS services. These roles and policies must be properly set up to allow the necessary permissions for NC2 to interact with AWS resources and perform required operations.

References:Refer to the AWS documentation on route table configuration and IAM roles and policies, and Nutanix documentation on NC2 cloud connectivity and permissions.

The Cluster Protect feature, which provides data protection and disaster recovery capabilities for Nutanix clusters, requires either the AOS Ultimate or NCI Ultimate license. These licenses include the necessary features to leverage Cluster Protect for ensuring data resilience and recovery.

Before accessing the Nutanix Cloud Clusters (NC2) console, the first step is to create a My Nutanix account.

This account serves as the primary gateway for managing and accessing Nutanix services, including NC2.

Once the account is created, users can log in to the Nutanix portal, where they can manage their subscriptions, start trials, and access various Nutanix services, including the NC2 console.

References:Refer to the Nutanix documentation on getting started with NC2 and the My Nutanix account creation process.

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.

For issues related to cloud hardware support such as EC2 instances, VPC, etc., the public cloud vendor (AWS in this case) should be contacted. AWS provides support and documentation for their infrastructure and services, ensuring that users can get assistance for any hardware or cloud-specific queries.

AHV (Answer A):

AHV (Acropolis Hypervisor) can be upgraded using Lifecycle Manager (LCM). LCM simplifies the upgrade process and ensures that all components are updated in a coordinated manner.

BIOS (Answer C):

BIOS upgrades can also be performed using LCM. This helps in maintaining hardware compatibility and performance by ensuring that the latest firmware is installed.

To provide VMs with outbound internet connectivity in AWS using a private subnet, the administrator needs to create the following components in the VPC:

Private Subnet: A private subnet is required to house the VMs that need outbound internet access but do not require direct inbound access from the internet.

NAT Gateway: A NAT (Network Address Translation) Gateway is necessary to allow instances in the private subnet to connect to the internet or other AWS services while preventing the internet from initiating a connection with those instances.

Public EIP (Elastic IP Address): An EIP is associated with the NAT Gateway to provide a persistent public IP address that allows outbound internet traffic from the private subnet to be routed correctly.

Route Table: A route table is configured to route traffic from the private subnet to the NAT Gateway for outbound internet access.

For a new NC2 on AWS deployment where workload VMs have low storage and memory requirements but high CPU frequency (>3.0 GHz) requirements, and the goal is to minimize the number of CPU cores to reduce application licensing costs, thei3.metalinstance type is the most suitable.

i3.metal:

High CPU Frequency: i3.metal instances offer high-frequency Intel Xeon processors (up to 3.1 GHz) which meet the high CPU frequency requirement.

Low Storage and Memory: These instances come with a balanced amount of storage and memory, suitable for workloads with low requirements in these areas.

Minimized CPU Cores: i3.metal instances have fewer CPU cores compared to other high-frequency instances like i4i.metal, making them ideal for minimizing application licensing costs.

Other Instance Types:

z1d.metal: While also offering high CPU frequency, these instances typically come with a higher core count and more memory, which may not be optimal for minimizing licensing costs.

i4i.metal: Designed for I/O intensive applications with higher core counts.

m5d.metal: Balanced instance type but with more cores and not as high CPU frequency as required.
