Authentic Nutanix Certification Exam NCP-DB Questions Answers

When an administrator is creating a Windows Domain profile in Era, the SQL Service Startup Account is an optional field that can be skipped and provided during the provisioning process. This account is used to start the SQL Server service when the server starts up. If this field is not provided during the creation of the Windows Domain profile, it can be provided later during the provisioning process1.

To ensure the NDB server, NDB agent, and NDB database agent can communicate with the registered cluster via REST API calls, port 2009 must be opened. This port is used by NDB components to facilitate RESTful communication with the Nutanix cluster (e.g., Prism Element or Prism Central) for operations such as provisioning, monitoring, and management. Proper firewall configuration to allow traffic on this port is a prerequisite for NDB’s integration with the cluster.

Other options are incorrect:

B. 3205: Not a standard NDB port; used for other Nutanix services.

C. 3260: Associated with iSCSI, not REST API communication.

D. 9440: Used for Prism Element’s HTTPS management interface, not NDB-specific REST calls.

Thus, the verified answer is A, reflecting NDB’s REST API requirements.

For an existing PostgreSQL database server managed by NDB, additional databases are added by updating the applicable database server parameters through the NDB graphical interface. The Database Parameters Profile represents PostgreSQL instance-level configuration and allows NDB to apply the supported database definition and configuration consistently. Creating additional Time Machines would protect separate database entities but would not create the databases themselves. A Software Profile contains the operating-system and PostgreSQL binaries used for provisioning database server VMs; replacing it is unnecessary for adding databases to an existing instance. A post-provisioning script is also not the standard managed workflow because it would bypass the profile-based configuration maintained by NDB. Therefore, option B is correct: the administrator should modify the Database Parameters Profile for the existing PostgreSQL server. Nutanix PostgreSQL Database Parameters Profile documentation
