In a Nutanix multisite DR configuration, a Protection Policy defines what VMs are protected and where their snapshots are replicated (e.g., to AZ1 and AZ2). However, a Recovery Plan defines the orchestration, boot order, and network mappings for failing over a specific set of VMs to a single, specific recovery AZ. To be able to fail over to the second recovery AZ, a separate and distinct Recovery Plan targeting that second AZ must be created. The inability to select the second AZ as a target indicates that no Recovery Plan has been configured for it.

A. Missing IP mapping would cause networking issues after failover is initiated but would not prevent the selection of a correctly configured Recovery Plan.

C. The snapshot retention count determines how many recovery points are available, not whether a site can be selected as a failover target.

D. The replication type (synchronous, asynchronous, etc.) does not restrict the creation of a Recovery Plan for a valid replication target.

1. Nutanix Prism Central Disaster Recovery Guide (pc.2023.4), "Recovery Plan Management". The documentation states: "A recovery plan orchestrates the recovery of protected VMs at a recovery AZ... A recovery plan specifies the recovery AZ." This implies a one-to-one mapping between a recovery plan and a target AZ. To target a second AZ, a second plan is needed.
