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.Reference:

The correct answer is D because it meets the requirements of maintaining five days of time-travel capability to any second and an additional seven days of discrete recovery at a daily interval. Continuous log retention allows the administrator to restore the database to any point in time within the specified number of days, while snapshot retention allows the administrator to restore the database to a specific point in time at a fixed interval. Therefore, by setting the daily snapshot retention to 7 days, the administrator can ensure that there is a discrete recovery point for each day of the week. By setting the continuous log retention to 5 days, the administrator can ensure that there is a time-travel capability to any second within the last five days. The other options do not meet the requirements because they either have less than five days of continuous log retention or less than seven days of snapshot retention.Reference:Nutanix Database Management & Automation (NDMA) course,Nutanix Certified Professional - Database Automation (NCP-DB) certification,Nutanix NCP-DB Certification Exam Syllabus and Study Guide,Nutanix Certified Professional - Database Automation (NCP-DB) datasheet

An NDB compute profile defines the CPU and memory resources for the database server VMs that are provisioned using NDB. It does not include any information about the network, domain, or software of the database server VMs. Those are specified in separate profiles, such as network profile, domain profile, and software profile.

NDB Multi-Cluster is a feature that allows multiple Nutanix clusters to share a common NDB service for database management and automation. NDB service consists of two components: NDB Server and NDB Agent. NDB Server is the central component that provides the web UI, REST API, and database orchestration logic. NDB Agent is the component that runs on each Nutanix cluster and communicates with the NDB Server to perform database operations.

When NDB Multi-Cluster is enabled on Cluster A, it becomes the primary cluster that hosts the NDB Server VM. Cluster B, which is registered with NDB, becomes a secondary cluster that hosts only the NDB Agent VM. Therefore, Cluster A has both NDB Server and NDB Agent, while Cluster B has only NDB Agent. This configuration allows Cluster B to leverage the NDB service running on Cluster A for database management and automation.

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

The correct answer is D because it matches the requirement of taking multiple snapshots per day and retaining them for one week. Option A is incorrect because it only takes one snapshot per day, which is not enough for the administrator's need. Option B is incorrect because it only retains the snapshots for one week, which means the older snapshots will be deleted after seven days. Option C is incorrect because it only takes two snapshots per week, which is not frequent enough for the administrator's need.

Time Machine is a feature of Nutanix Era that allows you to create and manage snapshots of your databases. You can use Time Machine to create clones from any snapshot, either manually or automatically. You can also configure Time Machine to create clones from snapshots based on a schedule, such as daily, weekly, or monthly. This way, you can ensure that your clones are always up to date with the latest data from your production databases. In this scenario, the most efficient way to meet the developer's requirement is to configure Time Machine to create a clone from a daily snapshot at 7:00am. This will save the developer's time and effort, as well as reduce the storage consumption by using the existing snapshots.Reference:

The correct answer is B because setting VM-Host affinity ensures that the DB Server VMs are not migrated to another host during the LCM upgrade process. This way, the DB Server VMs can continue to serve the database requests without interruption. Option A is incorrect because updating the Nutanix cluster does not prevent the DB Server VMs from being moved to another host. Option C is incorrect because removing the Nutanix cluster from NDB will make the DB Server VMs unmanaged by NDB and lose the benefits of NDB features. Option D is incorrect because unsetting VM-Host affinity will allow the DB Server VMs to be migrated to another host during the LCM upgrade process, which may cause downtime or performance degradation.
