Which configuration changes should be made to make sure the cluster meets the requirements?

An administrator needs to make sure an RF3 cluster can survive a failure of two complete racks without negatively affecting performance.

The current cluster configuration consists of the following:

• 30 All Flash Nodes: distributed 10 nodes per rack across three 42U racks

• Each node is configured with 20TB usable storage all flash (Cluster Total 600TB Usable)

• Current cluster utilization is 500TB storage

• Storage containers have Erasure Coding enabled

Which configuration changes should be made to make sure the cluster meets the requirements?
A . Expand the cluster to 50 nodes distributed evenly across 5 racks
B. Expand the cluster to 48 nodes distributed evenly across 6 racks
C. Expand the cluster to 60 nodes distributed evenly across 6 racks
