After a new NDB deployment, the administrator can test the provisioning capabilities using a database instance that is fully supported and readily configurable out of the box. PostgreSQL is the most suitable option because it is one of the core database engines supported by NDB from the initial deployment, with built-in provisioning templates and HA capabilities. NDB provides a streamlined process to provision PostgreSQL instances, making it an ideal choice for testing provisioning workflows, including VM creation, storage allocation, and network configuration.
Other options may require additional setup or licensing:
B. Oracle DB: Requires specific licensing and additional configuration, not typically available for initial testing.
C. MSSQL Server: Supported but may need Microsoft licensing and setup, less immediate than PostgreSQL.
D. MongoDB: Supported but less commonly used for initial testing due to its NoSQL nature and additional configuration needs.
Thus, the verified answer is A, reflecting PostgreSQL’s accessibility for testing.
