Nutanix Certified Master – Multicloud Infrastructure (NCM-MCI) — Question 14
An administrator needs to make sure an RF2 cluster can survive a complete rack failure without negatively effecting workload performance. The current cluster configuration consists of the following:
✑ 30 nodes: distributed 10 nodes per rack across three 42U rack
✑ Each nodes is configured with 40TB usable storage all flash (Cluster Total 1.2 PB Usable)
✑ Current cluster utilization is 900TB storage
Which configuration changes should be made to make sure that the cluster meets the requirements?
Answer options
- A. Expanse the cluster by adding 3 additional nodes per rack, 9 nodes total.
- B. Expanse the cluster by adding 2 additional nodes per rack, 6 nodes total.
- C. Expanse the cluster by adding 9 nodes to a new 42U rack
- D. Expanse the cluster by adding 8 nodes to a new 42U rack
Correct answer: A
Explanation
Adding 3 additional nodes per rack, for a total of 9 nodes, ensures that the cluster can handle the loss of an entire rack while maintaining performance and redundancy. The other options either do not provide enough nodes to meet the RF2 requirements or do not add nodes to existing racks, which is essential for redundancy in case of a rack failure.
