Nutanix NDB provides the ability to create highly-available (HA) database pairs, leveraging replication and failover across clusters. The two databases explicitly supported for HA pairs in NDB are PostgreSQL and SQL Server. NDB orchestrates HA for PostgreSQL using streaming replication and for SQL Server using Always On Availability Groups or Failover Cluster Instances, ensuring data redundancy and failover capabilities across Nutanix clusters.
Other options are not supported for HA pairs:
A. MySQL: MySQL is supported by NDB but lacks native HA pair configuration.
D. MariaDB: Similar to MySQL, MariaDB is managed by NDB but does not support HA pairs.
Thus, the verified answers are B and C, reflecting NDB’s HA capabilities.
