When synchronous replication has been configured and a planned failover is required for datacenter maintenance, Nutanix recommends performing aplanned failoverto ensure data consistency and a clean transition of services.

From theNutanix Enterprise Cloud Administration (ECA)course materials:

“A planned failover ensures that data replication is complete and consistent between the primary and standby sites before the workload is migrated. This prevents data loss and ensures seamless recovery.”

Additionally:

“A planned failover can be initiated either from the primary site or from the standby site. This provides flexibility depending on operational preferences and site availability during maintenance windows.”

“Unplanned failovers should only be used in the event of unexpected site outages or catastrophic failures, as they may involve data loss or incomplete synchronization.”

Therefore, the correct approaches are to conduct a planned failover either from the standby site (B) or from the primary site (D). This ensures seamless workload transition during the datacenter maintenance event.
