Nutanix NCP-CI-AWS Practice Exam Questions & Answers

Explanation AWS Directory Service needs to resolve the Nutanix gateway external API endpoint to authenticate and communicate with Nutanix services during cluster deployment. This falls under preparing the AWS environment and understanding the networking and DNS requirements before deployment begins. The other options would not be valid Nutanix service endpoints that Directory Service would need to reach.

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.

Explanation Once the free trial expires, continuing to use NC2 features requires switching to a paid subscription plan. The trial period is fixed and non-renewable. Without a paid plan in place after expiration, cluster functionality becomes unavailable. This is the standard path for converting from trial to production use.

Explanation

The requirement for two private subnets in the NC2 cluster configuration workflow serves the same purposes:

One subnet is designated for user VMs, ensuring user workloads are separated from management operations.

The other subnet is designated for cluster management, maintaining the integrity and security of management processes and internal communications.

Explanation

To ensure that only application servers from the source subnet 10.79.1.0/24 can access the SQL databases running on the NC2 cluster in the subnet 10.78.1.0/24, the administrator can take the following actions:

Option A: Create a custom Security Group with the following rules:

Key = tag:nutanix:clusters

Key = tag:nutanix:clusters:external

and value = the clusters' UUID

Key = tag:nutanix:clusters:external

and value = 10.78.1.0/24

Option D: Create a custom Security Group with the following:

Key = nutanix:clusters

Key = nutanix:clusters:external

and value = the clusters' UUID

Key = nutanix:clusters:external

and value = 10.79.1.0/24

These actions help create security rules that restrict access to the databases only from the specified source subnet, ensuring secure and controlled access.

Explanation

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.
