NCP-DB Premium Exam Questions

To release PostgreSQL HA instances using a dedicated subnet in Nutanix Database Service (NDB), the administrator must create a network profile that defines the subnet and its associated VLAN. Before creating this network profile, it is mandatory to add a VLAN to the NDB Networks configuration. This VLAN ensures that the dedicated subnet is recognized and manageable within NDB, allowing the HA instances to be provisioned with isolated network connectivity. The VLAN must be configured in the NDB Networks page to be available for selection during network profile creation.

Option A (The subnet in Prism Element must be IPAM configured) is incorrect because IP Address Management (IPAM) configuration in Prism Element is optional and not a mandatory prerequisite for creating a network profile in NDB.

Option B (The DB VMs must be registered first) is incorrect because VM registration is a subsequent step, not a prerequisite for network profile creation.

Option C (A VLAN must be added to NDB networks) is correct as it is a required step to define the network infrastructure before creating the profile.

Option D (Configure Network Segmentation) is incorrect because network segmentation is an advanced feature and not mandatory for basic network profile setup.

This ensures the dedicated subnet is properly integrated into NDB for HA provisioning.

Time Machine data access is a feature of Nutanix Database Service (NDB) that allows you to access a point-in-time snapshot of a database without restoring it. To use this feature, you need to create a Data Access Management (DAM) policy that defines the access mode, the source database, the destination cluster, and the storage container mapping. The storage container mapping is needed when the source database and the NDB Server containers are different, because NDB needs to know where to store the metadata and the clone of the source database. If the source database and the NDB Server containers are the same, then NDB will use the same container for both the metadata and the clone. References:

When downloading a list of alerts from NDB, the available file format is csv (Comma-Separated Values). NDB provides this format to export alert data (e.g., alert ID, timestamp, severity, description) in a structured, machine-readable way that can be easily imported into spreadsheet applications like Microsoft Excel or analyzed programmatically. This aligns with NDB’s focus on operational efficiency and data portability.

Other options are not supported:

A. xlsx: Excel’s native format is not offered by NDB for alert exports.

C. xml: Not a supported format for alert downloads in NDB.

D. pdf: Used for reports, not alert list exports.

Thus, the verified answer is B, reflecting NDB’s export capabilities.
