Nutanix NDB gives an administrator the ability to create highly-available database pairs with which two databases? (Choose two.)

Nutanix Database Service (NDB) provides built-in, automated high availability (HA) provisioning for specific database engines. For PostgreSQL, NDB configures a database cluster using Patroni, creating a primary server and one or more replicas for failover. For Microsoft SQL Server, NDB automates the deployment and configuration of Always On Availability Groups (AGs), which consist of a primary replica and one or more secondary replicas. While NDB supports managing MySQL and MariaDB, it does not offer a comparable integrated HA pairing feature during the initial provisioning workflow.

A. MySQL: NDB does not provide a native, automated HA pairing or clustering feature for MySQL during the provisioning process.
D. MariaDB: NDB does not provide a native, automated HA pairing or clustering feature for MariaDB during the provisioning process.
