Question 25 - NCP-CI-AWS discussion

To protect workloads on an NC2 cluster on AWS, deploying strategies that ensure high availability and disaster recovery are essential. The two valid options are:

Create a Second NC2 Cluster in a Different Availability Zone:

High Availability: Deploying a second NC2 cluster in a different availability zone ensures that workloads can be quickly recovered in case of an availability zone failure.

Disaster Recovery: This setup enables asynchronous replication between clusters, providing a robust disaster recovery solution.

Use an Existing On-Prem Nutanix Cluster as a Disaster Recovery Target:

Hybrid DR: Leveraging an existing on-premises Nutanix cluster for disaster recovery provides a cost-effective and efficient DR solution.

Replication: Set up replication policies to ensure data is consistently copied from the NC2 cluster on AWS to the on-premises cluster.

Why Not Other Options:

One-node cluster in another availability zone: Not a valid DR solution as a single-node cluster cannot provide the required resilience and high availability.

Deploy a cluster across two availability zones: While this can enhance availability, it is not a typical approach for Nutanix clusters which are designed to operate within a single availability zone for simplicity and performance reasons.
