                                          An architect is helping an organization with the Logical Design of an NSX-T Data Center solution. This information was gathered during the Assessment Phase:
                                          Customer currently has a single 10 host vSphere cluster.
                                          Customer wants to improve network security and automation.
                                          Current cluster utilization and business policies prevent changing the existing vSphere deployment.
                                          High-availability is important to the customer.
                                          Which three selections should the architect include in their design? (Choose three.)

                                          • A. Apply vSphere Distributed Resource Scheduler (vSphere DRS) VM-Host anti-affinity rules to NSX Managers.
                                          • B. Remove vSphere DRS VM-Host affinity rules to the NSX-T Controller VMs.
                                          • C. Remove 2 hosts from the cluster and create a new edge cluster.
                                          • D. Deploy the NSX Controllers in the management cluster.
                                          • E. Apply vSphere DRS VM-Host anti-affinity rules to the virtual machines of the NSX-T Edge cluster.
                                          • F. Deploy at least two NSX-T Edge virtual machines in the vSphere cluster.
