An administrator has an existing Nutanix seven-node cluster running at RF2 that must be changed to have the following capabilities:
✑ RF3 set for the cluster
✑ Performance tier deduplication
What is the minimum memory needed on the CVMs to allow for these capabilities?
To enable RF3 and performance tier deduplication on a Nutanix cluster, the Controller VMs (CVMs) must be configured with a minimum of 28 GB of memory. This includes the default 20 GB of memory for the CVM plus an additional 8 GB required to support these features.
Redundancy factor 3 has the following requirements: - Redundancy factor 3 can be enabled at the time of cluster creation or after creation too. - A cluster must have at least five nodes for redundancy factor 3 to be enabled. - For guest VMs to tolerate the simultaneous failure of two nodes or drives in different blocks, the data must be stored on containers with replication factor 3. -Controller VMs must be configured with a minimum of 28 GB(20 GB default+8 GB for the feature) of memory.

Agreed with Akane_ and anistuta, the answer is B.
