The provided exhibit shows the "Enable Multi-Cluster" configuration wizard in NDB, where the VLAN dropdown is empty with a "Nothing found" message, indicating that no VLANs are available for selection. This issue arises because NDB requires a network profile to be created before provisioning the NDB Agent VM and enabling multi-cluster support. A network profile defines the static VLANs managed by NDB, which are essential for network configuration during multi-cluster setup. The warning in the exhibit ("An NDB managed static vLAN is required to provision the NDB Agent VM. Add an NDB managed static vLAN using the Networks page to continue.") reinforces that the administrator must create a network profile via the Networks page to populate the VLAN dropdown.

Option A (A network profile must be created first) is correct as it addresses the root cause by ensuring VLANs are defined in a network profile.

Option B (Verify if subnet leverages advanced network control) is incorrect because advanced network control is not a prerequisite for VLAN selection in this context.

Option C (IP address pool must be managed in NDB) is incorrect because IP address pools are managed separately and not required for VLAN selection at this stage.

Option D (VLAN subnet must use IP address management) is incorrect because IP address management is not a direct requirement for enabling VLAN selection in the wizard.

After creating the network profile, the administrator can proceed with the multi-cluster enablement.

When consolidating Microsoft SQL Server instances on database server VMs managed by NDB using a medium compute profile, concerns about DB storage capacity can arise due to increased demand. In NDB, the appropriate task to address this is to "Update the Database Server VMs," which allows the administrator to adjust resource allocations, including storage capacity, for the VMs hosting the databases. This task can be performed within the NDB interface to expand disk space or reconfigure storage settings without altering the compute profile or requiring external tools.

Option A (Update the Database server VMs) is correct as it provides a direct method in NDB to modify VM resources, including storage.

Option B (Expand vDisk in Prism Element) is incorrect because NDB manages database VMs holistically, and storage expansion should be handled through NDB’s Update task rather than Prism Element directly.

Option C (Update the compute profile) is incorrect because compute profiles define CPU and memory, not storage capacity.

Option D (Scale the source database) is incorrect as scaling typically refers to database-level adjustments (e.g., adding nodes), not VM storage expansion.

This approach ensures seamless integration with NDB’s management framework.

 Nutanix Database Automation (NCP-DB) introduces the concept of MS SQL Server database groups, which allows multiple databases running in the same database instance to be grouped as one Time Machine entity1. This applies to both single DB Server VM setups, standalone databases, as well as to Availability Group databases1. However, it does not support Point In Time Recovery (PITR)-based Service Level Agreements (SLAs) for database groups containing mixed Recovery Models. This means that if the databases within the group have different recovery models, PITR-based SLAs cannot be applied to the group as a whole.

 In the context of Nutanix Database Automation (NCP-DB), a Super Admin has the authority to apply patch profiles. However, if a patch is marked as deprecated, even if it’s published, it cannot be applied. This is because deprecation is a status that indicates the patch is outdated or has been superseded by a newer version, and thus should not be used1. This behavior ensures that only the most up-to-date and secure patches are applied to the system, maintaining the integrity and security of the database environment1.

In the context of Nutanix Database Automation (NCP-DB), when there are insufficient resources on a development cluster, the administrator can adjust the Compute and Database Parameters profiles to make the copy fit within the available resources1. The Compute profile includes settings related to CPU and memory resources, which can be adjusted to fit within the available resources. The Database Parameters profile includes settings that control the behavior and resource usage of the database, which can also be adjusted to optimize resource usage1.

To migrate an existing Microsoft SQL Server (MSSQL) database to NDB, the recommended approach is to:

Provision a new database server VM and database: Use the NDB interface to provision a new VM and configure an MSSQL database instance on the Nutanix platform. This leverages NDB’s automated provisioning capabilities to ensure compatibility with Nutanix infrastructure.

Migrate the data: Transfer the data from the existing MSSQL database to the newly provisioned database. This can be achieved using native MSSQL tools (e.g., backup/restore, log shipping, or replication) or NDB’s data migration features, such as cloning or restoring from a backup, depending on the source environment.

Other options are incorrect or incomplete:

A. Use Nutanix Move to migrate the database server VM: Nutanix Move is designed for VM migration between platforms, not for database-specific migrations within NDB, which requires data migration to a new instance.

C. Create a new database server VM and database then register it with NDB: Registering an existing VM with NDB does not handle data migration from the source MSSQL database.

D. Backup your database VM and import it into Nutanix: Backing up the entire VM and importing it does not integrate the database with NDB’s management framework, and data migration would still be required separately.

Thus, the verified answer is B, providing a structured migration process tailored to NDB’s capabilities.

According to the Nutanix Database Automation (NCP-DB) learning documents, to configure Era to send alert notifications to email recipients, you need to go to the Administration section, select Era Service, then go to the configure notification widget. From there, you can update the SMTP server configuration1. This allows Era to use the SMTP server to send alert notifications to the specified email recipients1.
