Nutanix Certified Professional - Database Automation (NCP-DB) v6.5 Sample Questions (Q75-Q80):

NEW QUESTION # 75
An administrator needs to create a custom PostgreSQL HA software profile.
Which software component manages the state of the cluster and handles failover?

  • A. HAProxy
  • B. keepa lived
  • C. etcd
  • D. Patroni

Answer: D

Explanation:
NDB supports PostgreSQL HA software profiles for provisioning PostgreSQL databases with high availability. PostgreSQL HA software profiles consist of three components: etcd, HAProxy, and Patroni.
etcd is a distributed key-value store that provides a reliable way to store configuration data across a cluster of machines. etcd is used by Patroni to store and synchronize the cluster state and configuration.
HAProxy is a load balancer that distributes incoming requests to the PostgreSQL nodes. HAProxy is used to expose a single endpoint for database connections even as the roles of the individual nodes change.
Patroni is a template for PostgreSQL high availability. Patroni is responsible for managing the state of the cluster and handling failover. Patroni uses etcd as the distributed configuration store and relies on HAProxy for load balancing.
Therefore, the software component that manages the state of the cluster and handles failover is Patroni.

NEW QUESTION # 76
An administrator needs to patch a PostgreSQL database server VM from version 13.4 to 13.8.
What is the first step within the NDB patching workflow to accomplish this task?

  • A. Create a Software Profile Version with PostgreSQL 13.8.
  • B. Create a new Database Parameters profile for PostgreSQL server 13.8.
  • C. Create a new Software Profile with PostgreSQL 13.8.
  • D. Create a maintenance window and add this PostgreSQL server 13.8 to the queue.

Answer: A

Explanation:
NDB supports patching for PostgreSQL database instances. Patching for PostgreSQL is validated on VMs provisioned by NDB (greenfield deployments). To patch PostgreSQL database server VMs, you must create a software profile version by uploading the PostgreSQL update file in NDB. You can then use the PostgreSQL update to patch other database server VMs or provision a new database server VM with the updated software profile. The first step in the NDB patching workflow is to create a software profile version with the desired PostgreSQL version.

NEW QUESTION # 77
An administrator enables NDB Multi-Cluster on Cluster A. Cluster B is then registered with NDB.
What are the different NDB Service VMs present in each Nutanix cluster?

  • A. Cluster A: 1 NDB Server, 1 NDB Agent
    Cluster B: 1 NDB Agent
  • B. Cluster A: 1 NDB Server
    Cluster B: 1 NDB Agent
  • C. Cluster A: 1 NDB Agent
    Cluster B: 1 NDB Server, 1 NDB Agent
  • D. Cluster A: 1 NDB Agent
    Cluster B: 1 NDB Server

Answer: A

Explanation:
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.

NEW QUESTION # 78
What are the three severity levels displayed under the Alert dashboard?

  • A. Failed, Warning, Error
  • B. Critical. Waiting, Failed
  • C. Critical, Warning Info
  • D. Failed, Warning, Stopped

Answer: C

Explanation:
The Alerts dashboard in Nutanix displays alert messages with three severity levels: Critical, Warning, and Info1. These severity levels help users understand the importance and urgency of each alert, allowing them to prioritize their responses accordingly1.


NEW QUESTION # 79
An administrator was asked to change the snapshot schedule for a given database. The administrator discovered that the time machine is in a paused state.
How should the administrator change the schedule?

  • A. Clone the Time Machine and define an appropriate schedule for the clone.
  • B. Clone the database and define an appropriate schedule for the clone.
  • C. Select the Time Machine; under Action select Update end define an appropriate schedule.
  • D. Select Time Machine: Under actions Resume the Time Machine and then Update to define an appropriate schedule.

Answer: C

Explanation:
According to the Nutanix Database Automation (NCP-DB) learning documents, an administrator can change the snapshot schedule for a given database by selecting the Time Machine, then under Action, select Update and define an appropriate schedule1. This is because the Time Machine in Nutanix Era allows you to specify the number of backups or snapshots the time machine should take, the time of day it takes those snapshots, and the day of the week it takes weekly or monthly backups1. These options help you build a complete schedule of time machine capture operations1. Even if the Time Machine is in a paused state, the administrator can still update the schedule1. Cloning the Time Machine or the database is not necessary for changing the snapshot schedule1.
