Nutanix Certified Professional NCP-CI-AWS Exam Questions and Answers PDF

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.

The clusters that are to be protected must be registered with the same instance of Prism Central (Answer C):

For Cluster Protect to function correctly, all clusters intended for protection must be registered under the same Prism Central instance. This ensures consistent management and coordination of protection policies and operations across clusters.

The Cluster Protect feature requires AOS version 6.7 or higher (Answer D):

Cluster Protect is a feature that is available starting from AOS version 6.7. To utilize this feature, ensure that the Nutanix clusters are running this version or a newer one.
