Question 5 of 60
5. Question
An administrator needs to provision multiple database clones from the same source database for different purposes, such as QA and Test/Development. To avoid resource contention, the administrator wants to differentiate VM resources for each department. What is the most efficient way to accomplish this task?
Correct
Creating multiple compute profiles is a good starting point. Compute profiles allow you to define vCPU, memory, and vNUMA settings, enabling you to customize the resources allocated to each clone. This helps ensure that resource-intensive database clones for one department don‘t starve others.

Question 17 of 60
17. Question
An administrator needs to restore databases provisioned with a shared disk configuration on Windows Storage Spaces. What happens when NDB runs the restore procedure?
Correct
The process involves replacing the source volume with the snapshot volume if the source volume only contains database files for the single database being restored. If the source volume contains other database files not included in the restore operation, the source volume is not replaced. Instead, NDB mounts the snapshot and copies only the necessary database files to the source volume, leaving other database files untouched.

Question 19 of 60
19. Question
During maintenance, a team wants to power off the repository VM. The VM is not the primary or synchronized copy node. What is the expected behavior?
Correct
Powering off a repository VM that isn‘t the primary or a synchronized copy node should not interrupt service. Other repository VMs will continue to function, ensuring continued service availability. However, powering off this VM might impact redundancy and availability if other repository VMs fail. This is because that VM is no longer available to step in if needed.

Choose a storage container, provide a name and description, and select the image type as “Disk“. After the upload completes, you can proceed with creating the NDB virtual machine.

What happens to the primary member in a MongoDB Server Cluster during the NDB update process?
Correct
Secondary Members Patched First: Any secondary members (including asynchronous and synchronous replicas) are patched before the primary. Failover for Primary Patching: To patch the original primary node, a failover is initiated. This promotes a secondary member to become the new primary. The original primary, now a secondary, is then patched.

Question 46 of 60
46. Question
Which policies govern Time Machine data availability across multiple registered clusters in NDB?
Correct
Nutanix NDB‘s multi-cluster capability uses Data Access Management (DAM) policies to manage Time Machine data availability across registered Nutanix clusters.
