Question 1
An administrator has been tasked with ensuring NC2 VMs are able to access AWS resources. The NC2
VM traffic must not traverse the internet.
in which two ways would the administrator achieve this? (Choose two.)
- A. By using a Gateway Endpoint
- B. By using a NAT Gateway.
- C. By using an Interface Endpoint
- D. By using a VPC Peer.
Answer:
CD
Explanation:
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.

Question 2
During the recovery of entities protected by Cluster Project, an administrator discovers that the
recovery plan is not executing correctly because it exceeds the number of supported entities.
How many entities can be recovered using a Single recovery plan?
- A. 100
- B. 200
- C. 300
- D. 400
Answer:
C
Explanation:
The Nutanix disaster recovery capabilities include recovery plans that define how entities are
recovered in the event of a failure. There is a limit to the number of entities that can be managed
within a single recovery plan.
Entity Limit:
According to Nutanix documentation, the maximum number of entities that can be recovered using a
single recovery plan is 300. Exceeding this limit will cause issues during the execution of the recovery
plan.
Impact of Exceeding the Limit:
If the number of entities in a recovery plan exceeds the supported limit, the recovery process may
fail or not execute correctly, as observed in the scenario.

Question 7
An administrator is planning a new NC2 on AWS deployment. The workload VMs to be deployed on
the new cluster have low storage and memory, but high CPU frequency (>3.0 GHz) requirements.
The administrate! has also been tasked with ensuring that the cluster nodes have the lowest number
of CPU cores to reduce application licensing requirements.
Which node type will satisfy this new deployment?
- A. i3.metal
- B. zld.metal
- C. i4i.metal
- D. m5d.metal
Answer:
A
Explanation:
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, the i3.metal instance 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.

Question 9
An administrator is tasked with adding an AWS account to the NC2 console. A requirement is to
configure an AWS IAM user with the appropriate permissions.
Which permission must be assigned to the user?
- A. lAMFullAccess
- B. lAMReadOnlyAccess
- C. AmazonEC2ReadOnlyAccess
- D. AmazonEC2FullAccess
Answer:
D
Explanation:
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.

Question 10
An administrator has created an NC2 cluster on AWS, but the NC2 console has issued this alert:
Which two scenarios could have resulted in the cluster creation failure? (Choose two.)
- A. Bad Terraform (TF) state in provisioning
- B. Insufficient permissions
- C. No available AWS credits
- D. AWS Quota exceeded/instance limit exceeded
Answer:
BD
Explanation:
The error message in the image indicates that the cluster creation failed due to reaching the
maximum retries for provisioning cluster nodes. Here are two possible scenarios that could lead to
this issue:
Insufficient Permissions (Answer B):
If the AWS user or role used to create the cluster does not have sufficient permissions, it can result in
failures during the provisioning process. Proper IAM policies must be attached to ensure that the
necessary actions can be performed, such as launching instances, creating VPCs, or managing
networking components.
AWS Quota Exceeded/Instance Limit Exceeded (Answer D):
AWS imposes quotas and limits on the number of instances and other resources that can be created
within an account. If these quotas are exceeded, new instances cannot be provisioned, causing the
cluster creation to fail. This can be resolved by requesting a quota increase from AWS.
