Which cluster expansion type should be selected when expanding the second cluster using the SDDC Manager UI?

The administrator for an existing VMware Cloud Foundation instance has one management domain (sfo-m01) and one workload domain (sfo-w01). The workload domain consists of two vSphere clusters (sfo-w01-ci01 and sfo-w01-cl02) using vSAN as principle storage.

The workload domain also includes an NSX-T Edge Cluster deployed in the default cluster(sfo-w01-c01) of the workload domain. The first cluster (sfo-w01-c01) rack1, and the second cluster (sfo-w01-c01) resides in rack 1.

A new project is underway, and the capacity of the second cluster (sfo-w0I cl02) of the workload domain that willbe consumed by vRealizeAutomation needs to be expanded Rack 1 is at capacity. Eight additional hosts have been placed in rack 2 and cabled within the new rack.The network architecture is an L3 spine leaf architecture.
