In addition to the comprehensive material, a few basic and important questions are highlighted and discussed in the NCP-DB Exam Material file. These questions are repeatedly seen in past Nutanix Certified Professional - Database Automation (NCP-DB) v6.5 exam papers. The Nutanix Certified Professional - Database Automation (NCP-DB) v6.5 practice questions are easy to access and can be downloaded anytime on your mobile, laptop, or MacBook.
NEW QUESTION # 108
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.)
Answer: B,C
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 v7.5.
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 # 109
An administrator needs to create and refresh clones to a point in time.
NDB allows which two methods for satisfying this requirement? (Choose two.)
Answer: C,D
Explanation:
NDB allows creating and refreshing clones to a point in time using two primary methods:
B). Snapshots: NDB uses storage snapshots (e.g., via Nutanix Volumes or AHV) to capture the database state at a specific point. These snapshots can be used to create or refresh clones, providing a consistent recovery point.
D). Transaction logs: Transaction logs (e.g., PostgreSQL WAL, SQL Server logs) enable point-in-time recovery (PITR) by applying logs to a snapshot, allowing clones to be refreshed to a precise moment.
Other options are not supported for this purpose:
A). Full backups: Full backups are used for complete restores but are not optimized for frequent clone refreshes.
C). VM snapshots: VM-level snapshots (e.g., AHV snapshots) are not managed by NDB for database cloning, as they lack database consistency.
Thus, the verified answers are B and D, reflecting NDB's clone refresh capabilities.

NEW QUESTION # 110
Where can an administrator configure a custom SSL certificate for Era?
Answer: D
Explanation:
An administrator can configure a custom SSL certificate for Era through the Era User Interface (UI)1. This can be done by logging into the Nutanix Console and selecting SSL Certificates from the drop-down list inside the gear icon23. In the SSL Certificate dialog box, the administrator can click Replace Certificate, then select the Import Key and Certificate radio button23. This process ensures secure communication within the Nutanix Era environment4.
NEW QUESTION # 111
An administrator needs to create a custom PostgreSQL HA software profile.
Which software component manages the state of the cluster and handles failover?
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 # 112
How can HA drivers for a Database VM be upgraded?
Answer: A
Explanation:
HA drivers are software components that enable high availability features for database VMs, such as failover, fencing, and heartbeat. HA drivers can be upgraded using the Life Cycle Management (LCM) feature of Nutanix Prism. LCM can detect the available updates for HA drivers and apply them to the database VMs in a non-disruptive manner. LCM can also perform health checks and pre-upgrade validations to ensure the successful completion of the upgrade process. One-click software upgrade is a feature of Nutanix Era that allows you to upgrade the Era software itself, not the HA drivers. Database VM OS patching is a feature of Nutanix Era that allows you to patch the operating system of the database VMs, not the HA drivers. Database software patching is a feature of Nutanix Era that allows you to patch the database software of the database VMs, not the HA drivers. References:
