Nutanix Certified Associate Practice Exam

Which option describes a necessary step when transitioning a Nutanix cluster to support RF3?

1. Perform a complete backup of all data.

2. Adjust the storage policy to standardize deduplication.

3. Increase the memory of the cluster's CVMs to meet new requirements.

4. Consult the vendor for compatibility checks.

The correct answer is: Increase the memory of the cluster's CVMs to meet new requirements.

Increasing the memory of the cluster's Controller Virtual Machines (CVMs) to meet new requirements is an essential step when transitioning a Nutanix cluster to support Replication Factor 3 (RF3). In this configuration, data is stored in three copies across different nodes in the cluster to enhance data availability and fault tolerance. This increased replication demands more memory and resources from the CVMs because they need to manage additional data copies effectively. As RF3 increases the redundancy of data, it requires adequate computational resources, including memory, to ensure optimal performance and management of those replicas. It is crucial for the CVMs to have sufficient memory to handle the scheduling, coordination, and maintenance of the additional data copies, which helps to prevent performance bottlenecks. Having the right amount of memory in the CVMs ultimately supports robust data management and ensures that the cluster can function optimally with the increased data load associated with RF3.
