The correct answer is D. Expand the cluster with the new node. In a three-node cluster, removing a node before adding the replacement would leave only two nodes, which drops below the minimum required for Nutanix cluster quorum and redundancy (RF2 requires at least 3 nodes).

Explanation
In a three-node cluster, removing a node before adding the replacement would leave only two nodes, which drops below the minimum required for Nutanix cluster quorum and redundancy (RF2 requires at least 3 nodes). The correct approach is to first expand the cluster with the new (replacement) node-making it temporarily a four-node cluster-and then remove the old node. This maintains fault tolerance and data redundancy throughout the entire replacement process. Verifying hypervisor versions and plugging in cables are steps that happen as part of the process, but expanding first is the critical prerequisite.
