Nutanix Certified Professional - Database Automation (NCP-DB) v6.5 Sample Questions (Q194-Q199):

NEW QUESTION # 194
An administrator needs to work with databases and time machines, but not database parameter profiles. Which role satisfies this requirement?

A. Infrastructure Administrator
B. Database Infrastructure Administrator
C. super Administrator
D. Database Administrator (DBA)

Answer: D

Explanation:
In the Nutanix Database Automation (NCP-DB) framework, the role that allows an administrator to work with databases and time machines, but not database parameter profiles, is the Database Administrator (DBA)123.
This role provides the necessary permissions to manage databases and time machines, which are essential components of the Nutanix Era solution. However, it does not grant access to database parameter profiles, which are typically managed by other roles45.

NEW QUESTION # 195
An NDB administrator is looking to free up some space consumption in the container that NDB uses to manage a database landscape.
Where are two of the best locations within NDB that the administrator could view to see where the most storage is being consumed, in order to research for reclamation? (Choose two.)

A. View the Snapshot table in Time Machine to determine Reclaimable Space and Age of snapshots that have been taken.
B. View the Clone Database table to determine the Size and Last Refresh of clone databases.
C. View the Source Database grid to determine the size and status of registered databases.
D. NDB Dashboard and view the Clone Data Age in days.

Answer: A,B

Explanation:
To free up space in the NDB-managed container, the administrator needs to identify storage consumption sources. Two key locations in NDB provide actionable insights:
* C. Clone Database table: This displays all clone databases, including their Size (current storage usage) and Last Refresh (indicating age or staleness). Clones often consume significant space, and older or unused ones can be deleted to reclaim storage.
* D. Snapshot table in Time Machine: This shows snapshots with details like Reclaimable Space (space recoverable by deletion) and Age (how long snapshots have existed). Old or unnecessary snapshots are prime candidates for reclamation.
Why not the other options?
* A. NDB Dashboard (Clone Data Age): While it provides a high-level view, it lacks granular details (e.
g., size per clone) needed for targeted reclamation.
* B. Source Database grid: This shows registered databases' size and status but doesn't focus on derivative objects (clones/snapshots) that typically consume more space.
Thus, C and D are the best locations for detailed storage analysis and reclamation research.

NEW QUESTION # 196
A database administrator is working with a cloned database and creates a clone removal schedule.
Which two default actions are taken on the cloned database? (Choose two.]

A. NDB marks the cloned database as offline.
B. NDB deletes the cloned database.
C. NDB deletes the cloned database VM.
D. NDB de-registers the cloned database.

Answer: B,D

Explanation:
When a database administrator creates a clone removal schedule in NDB, the system automates the cleanup of cloned databases based on the defined schedule (e.g., after a set retention period). The two default actions taken on the cloned database are:
* A. NDB deletes the cloned database: The clone's data is removed from storage to free up space.
* B. NDB de-registers the cloned database: The clone is removed from NDB's management inventory, ensuring it no longer appears in the GUI or is tracked.
Other options are not default actions:
* C. NDB marks the cloned database as offline: This is a temporary state, not a removal action.
* D. NDB deletes the cloned database VM: Deleting the VM is not automatic; it depends on the clone type (e.g., linked clones retain the VM).
Thus, the verified answers are A and B, aligning with NDB's clone management.

NEW QUESTION # 197
A new web application performs up to 200 concurrent connections to a PostgreSQL database. An administrator needs to configure the system to provision those DB servers.
Which action would easily help the administrator achieving this goal?

A. Provision a PostqreSQL HA Instance.
B. Create a new Database Parameters profile.
C. Use Post Create Command when provisioning the DB.
D. Edit the API equivalent shell script to apply the setting.

Answer: A

Explanation:
A new web application with up to 200 concurrent connections to a PostgreSQL database requires a robust and scalable configuration. Provisioning a PostgreSQL HA (High Availability) instance in NDB is the most effective action to achieve this goal. An HA instance leverages replication (e.g., streaming replication) to distribute load and ensure availability, accommodating high concurrency by allowing multiple nodes to handle traffic. This approach simplifies configuration compared to manual scripting or parameter adjustments.
* Option A (Use Post Create Command when provisioning the DB) is incorrect because post-create commands are for custom scripts, not optimal for handling concurrent connections.
* Option B (Create a new Database Parameters profile) is incorrect because while it can tune settings, it's less efficient than HA for scaling concurrency.
* Option C (Edit the API equivalent shell script) is incorrect as it's a manual and error-prone method compared to HA provisioning.
* Option D is correct because a PostgreSQL HA instance natively supports high concurrency and availability.
Note: The typo "PostqreSQL" is assumed to mean "PostgreSQL."

NEW QUESTION # 198
An administrator needs to restore a database provisioned on Storage Spaces. The virtual disks are shared with multiple databases.
Which restore method is supported?

A. Copy-based restore via NDB GUI
B. Disk-based restore via NDB CLI
C. Disk-based restore via NDB GUI
D. Copy-based restore via NDB CLI

Answer: A

Explanation:
For restoring a database provisioned on Storage Spaces, especially when virtual disks are shared among multiple databases, the supported method is a copy-based restore via the NDB GUI. This method allows for a precise and controlled restoration process suitable for shared storage environments.References:Nutanix Database Automation documentation, specifically in the section on database restoration methods and storage spaces.
