Nutanix Certified Professional - Database Automation (NCP-DB) v6.5 Sample Questions (Q208-Q213):

NEW QUESTION # 208
A Linux OS is running a PostgreSQL instance that is managed by NDB. This instance is not working properly after a manual OS update, so an administrator has prepared a new Linux DB server VM that is ready to host the data from the broken DB.
Which action should the administrator perform to migrate data to the new DB server VM?

  • A. Provision a new PostgreSQL instance from the Databases page.
  • B. From The Machine policy, Authorize Database Sever VMs.
  • C. Register the new DB Server VM in NDB.
  • D. Follow the Provision a PostgreSQL Instance wizard.

Answer: C

Explanation:
In this scenario, a PostgreSQL instance managed by NDB on a Linux VM is malfunctioning after a manual OS update, and a new Linux DB server VM has been prepared to host the data. To migrate the data to the new VM, the administrator must integrate the new VM into NDB's management framework. The correct action is to register the new DB Server VM in NDB, which allows NDB to recognize and manage the VM as a database server. Once registered, the administrator can use NDB's features (e.g., cloning, restoring, or reprovisioning) to migrate the data from the broken instance to the new VM.
Here's why the other options are incorrect:
* A. Provision a new PostgreSQL instance from the Databases page: This creates a fresh instance without migrating existing data, losing the broken instance's data unless separately restored.
* B. From The Machine policy, Authorize Database Server VMs: Machine policies in NDB define rules for VM management, but authorizing VMs is not a direct migration action and assumes prior registration.
* C. Follow the Provision a PostgreSQL Instance wizard: Similar to A, this provisions a new instance rather than migrating data to an existing prepared VM.
Registering the new VM in NDB (via the "Database Server VMs" section) enables the administrator to associate it with the existing PostgreSQL instance's configuration and perform a data migration (e.g., using a snapshot or backup). This aligns with NDB's workflow for replacing a broken server. Thus, the verified answer is D.

NEW QUESTION # 209
An administrator is looking to provision a relational database management system (RDBMS) in an HA instance. Which two database engines are supported with NDB? (Choose two.)

  • A. MariaDB
  • B. Oracle
  • C. MongoDB
  • D. PostgreSGL

Answer: B,D

Explanation:
Nutanix Database Service (NDB) supports high availability (HA) instances for certain relational database management systems (RDBMS). Among the listed options, NDB natively supports Oracle and PostgreSQL for HA configurations, enabling features like replication and failover. These databases are well-integrated with NDB's Time Machine and HA frameworks.
* Option A (MongoDB) is incorrect because MongoDB is a NoSQL database, not an RDBMS, and is not supported for HA instances in NDB.
* Option B (MariaDB) is incorrect because, while MariaDB is an RDBMS, it is not currently supported for HA instances in NDB v6.10.
* Option C (Oracle) is correct as NDB supports Oracle in HA mode with features like Data Guard integration.
* Option D (PostgreSQL) is correct as NDB supports PostgreSQL HA with streaming replication.
Note: The typo "PostgreSGL" in the question is assumed to mean "PostgreSQL" based on context.

NEW QUESTION # 210
Which response shows two ways to upgrade an NDB Server?

  • A. One-click Upgrade and In-place Upgrade Auto
  • B. Out-of-Place Upgrade and In-place Upgrade
  • C. One-click Upgrade and Offline Upgrade
  • D. Upgrade and Manual Upgrade

Answer: C

Explanation:
There are two ways to upgrade an NDB Server: one-click upgrade and offline upgrade. One-click upgrade is the recommended method, as it automatically downloads and installs the latest NDB software version from the Nutanix portal. Offline upgrade is an alternative method, which requires you to manually download the NDB software bundle and upload it to the NDB Server VM. Both methods require you to have a valid Nutanix account and an internet connection. References:

NEW QUESTION # 211
Which ports are used by the NDB database agent for API calls?

  • A. 5985 and 9389
  • B. 443 and 8080
  • C. 3205 and 3260
  • D. 443 and 9440

Answer: D

Explanation:
The NDB database agent is a service that runs on each database server VM and communicates with the NDB instance. It uses port 443 for HTTPS API calls and port 9440 for Nutanix cluster API calls. These ports are required to be open on the database server VMs for NDB to function properly.

  • B. Time Machine Cloud Orchestration
  • C. Global Data Protection
  • D. Data Access Management

Answer: A

Explanation:
The Global Service Level Agreement (SLA) feature of Era allows an administrator to create Time Machine policies in a Multi-Cluster configuration1. This feature provides a unified way to manage and enforce backup and replication policies across multiple clusters, ensuring consistent data protection and recovery across the entire environment1.
