   A VxRail cluster has four nodes, each with a single vSAN disk group. The administrator needs to remove one node to repurpose it for a lab environment. The cluster is currently healthy, but the administrator is concerned about data redundancy during the removal. What should the administrator do before starting the removal?

   • AConfirm that the node to be removed is running the oldest ESXi version in the cluster.
   • BVerify that the node to be removed is the only node hosting the vSAN witness component.
   • CEnsure the cluster has sufficient free capacity to rebuild the data from the node being removed onto the remaining nodes.
   • DDisable the vSAN health checks to avoid false alarms during the removal process.

   A VxRail cluster has four nodes, each with 10 TB of raw storage. The cluster is using a vSAN storage policy with FTT=1. The administrator needs to remove one node to repurpose it for a development environment. The cluster currently has 15% free capacity. The administrator is considering two options: (1) proceed with the removal, or (2) add a new node before removal. What is the best decision?

   • AChange the storage policy to FTT=0 before removal to reduce capacity requirements.
   • BAdd a new node before removal to ensure sufficient capacity for data rebuild.
   • CProceed with the removal because 15% free capacity is sufficient for FTT=1.
   • DRemove the node and then add a new node if the cluster becomes unhealthy.

   A VxRail cluster has eight nodes, and the administrator needs to remove two nodes to repurpose them for a different project. The cluster is healthy, and the storage policy is FTT=1. What is the most important consideration before removing both nodes?

   • AChange the storage policy to FTT=0 before removing the nodes to reduce capacity requirements.
   • BEnsure that the cluster has enough free capacity to rebuild data from both nodes while maintaining FTT=1.
   • CVerify that the two nodes are not in the same rack to avoid a rack-level failure.
   • DRemove the nodes one at a time, waiting for the cluster to fully rebalance between removals.

   After removing a node from a VxRail cluster, the administrator wants to confirm that the cluster is fully operational. Which action is the most reliable way to verify the cluster's health post-removal?

   • AVerify that the removed node is no longer visible in the vSphere client inventory.
   • BCheck the vCenter alarm list to ensure no new alarms have been generated.
   • CReview the vSAN performance metrics to ensure IOPS are within normal range.
   • DRun a cluster health check from VxRail Manager and verify that all checks pass.

   An administrator is planning to remove a node from a VxRail cluster. The cluster has been running for months, and the administrator wants to ensure no hidden issues will cause the removal to fail. Which pre-removal check is most important to perform?

   • ARun a full cluster health check and verify that all components are in a healthy state.
   • BVerify that the node to be removed has the least amount of data stored on it.
   • CConfirm that the node to be removed is not the primary node of the cluster.
   • DCheck the warranty status of the node to be removed.
