In NDB, database groups are used to manage multiple Microsoft SQL Server databases collectively, enabling centralized administration and protection policies. The statement 'Databases within a database group can share multiple Time Machine configurations' is true. A Time Machine in NDB manages snapshots and log backups for recovery, and a database group can be associated with multiple Time Machine configurations to support different retention policies or recovery point objectives (RPOs) for the databases within the group. This flexibility allows tailored data protection strategies.

Other options are incorrect:

A . Microsoft recommends 35 databases within a single database group: There is no specific Microsoft recommendation for this limit; NDB imposes its own constraints based on performance and resource usage.

C . NDB supports one database group per database server VM or database server cluster: NDB allows multiple database groups per server or cluster, depending on configuration.

D . Databases within a database group must be all of the same size: NDB does not enforce uniform database sizes within a group.

Thus, the verified answer is B, reflecting NDB's Time Machine flexibility.

An NDB Software Profile is a template of the OS and database engine that you can use to provision or clone database server VMs using NDB. To create a software profile, you need to upload an installer package for the database software that you want to use, such as SQL Server or Oracle. The installer package must be compatible with the OS image that you have registered with Prism Element. You do not need a database server VM registered with NDB, a patch file for the installed databases, or an OS image registered with Prism Element to create a software profile. Those are required for other tasks, such as creating a software profile version, registering a database server VM, or provisioning a database server VM.

NDB SLAs are service level agreements that define the data protection and recovery objectives for NDB-managed databases. NDB SLAs consist of data retention policies that specify how long the snapshots and log backups of a database are kept in the Time Machine. Data retention policies can be customized to meet different business and compliance requirements, such as daily, weekly, monthly, or yearly retention periods. NDB SLAs also determine the frequency and schedule of the snapshots and log backups, as well as the storage location and replication options. An administrator who is tasked with auditing NDB SLAs will be reviewing the data retention policies of each database and Time Machine, as well as the snapshot and log backup history and status. The administrator will also be able to monitor the storage usage and performance of the NDB SLAs, and modify or delete the SLAs as needed. The other options are not part of the NDB SLAs, but rather separate features or concepts of NDB. Snapshot schedules are the intervals at which NDB takes snapshots of the databases, which are determined by the SLAs. Clone management is the process of creating, refreshing, or deleting database clones from the Time Machine. Recovery time objective (RTO) is the maximum acceptable time for restoring a database after a failure, which is influenced by the SLAs, but not defined by them.Reference::

The Era One-Click Provisioning service in Nutanix Database Automation (NCP-DB) simplifies and automates database administration. It brings one-click simplicity to database provisioning and life-cycle management. This service enables database administrators to provision, clone, and refresh the database clones to any point in time1. Specifically, it enables the creation of space-efficient clones and zero-byte database clones1. This is part of Era's copy data management service, which includes components like Time Machine, one-click cloning and refresh, and one-click backup21.

To install NDB on a Nutanix AHV cluster, you need to download the QCOW2 image file of NDB from the Nutanix Support Portal and upload it to Prism Element. This image file contains the NDB software and the CentOS operating system. After uploading the image, you need to create a VM from the image and configure the network settings. Then, you need to register the NDB VM with Prism Central and enable the NDB service in the settings menu.Reference::Nutanix Support & Insights,Professional Services: NDB Database Cloning
