Question
An administrator is upgrading a current three-node Nutanix cluster with new HCI nodes. Currently, the environment is based on a Single two-unit chassis hosted in one cabinet. By simply changing the system form factor, what new level of resiliency may this customer achieve?
Options
- ARack awareness
- BBlock awareness
- CMetro Availability
- DBetter replication factor

Explanation
Nutanix Block Awareness is a data placement policy that distributes data replicas across separate physical blocks (chassis enclosures) so that if an entire block loses power or fails, no data is lost. The customer's current environment uses a single two-unit chassis, meaning all nodes share the same chassis - a block failure would bring down the whole cluster. By moving to separate HCI nodes housed in distinct chassis (blocks), Nutanix can enforce block-aware data placement, ensuring replicas never share the same block. Rack Awareness (A) is a higher-level concept requiring nodes spread across multiple racks, not just separate chassis. Metro Availability (C) is a stretched-cluster DR feature requiring two geographically separated sites. A better Replication Factor (D) is a separate setting (RF2 vs RF3) unrelated to chassis form factor.
