Nutanix NCP-DB Dumps Questions Answers

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.

 According to the Nutanix Database Automation (NCP-DB) learning documents, to refresh an existing DB Clone, a developer with RBAC privileges in Era needs to navigate to Databases > Clones. From there, they select the appropriate clone from the table, click Refresh, select the desired Point In Time or Snapshot, and then click Refresh12. This process allows the developer to update the cloned database3.

 An Infrastructure Administrator is a role in NDB that has the permission to manage network and storage resources, such as VLANs, IP Pools, and Storage Containers. This role is suitable for the engineer who needs to add new VLANs or IP Pools in NDB. The other roles have either more or less privileges than required for this task. A Database Administrator can manage databases and database server VMs, but not network and storage resources. A Super Administrator can manage all aspects of NDB, but this is more than the least-privilege access needed. A Database Infrastructure Administrator can manage both databases and network and storage resources, but this is also more than the least-privilege access needed.
