An administrator would like to use Era for Copy Data Management operations on an Availability Group (AG) database. The AG database is hosted on replicas with different named instances, as shown below:
- SQLAGNIEMR
- SQLAGN2EMR
- SQLAGN3DW
SQLAGN3DW is running the Analytics service that needs real-time data. How should the administrator register the database in Era?
A. Register the database as a Standalone database,
B. Register the SQLAGN3 from AG cluster and register the database as Availability database,
C. Register the database as an Availability database.
正解：C
解説：
According to the Nutanix Database Automation (NCP-DB) learning documents, when dealing with an Availability Group (AG) database, the database should be registered as an Availability database. This is because the AG database is hosted on replicas with different named instances, and registering it as an Availability database allows for Copy Data Management operations to be performed across all instances. This is particularly important when services such as the Analytics service running on SQLAGN3DW require real-time data.
質問 # 217
An NDB administrator has asked a database administrator to provision a new MongoDB database using an existing software profile. The database administrator is unable to complete this action.
What may be the cause?
A. The software profile is undergoing a patching operation.
B. The software profile was created by another user.
C. A database clone operation is in progress.
D. The administrator lacks the proper permissions in Prism Element.
正解：D
解説：
If a database administrator is unable to provision a new MongoDB database using an existing software profile, the most likely cause is that the administrator lacks the proper permissions in Prism Element. NDB relies on Prism Element for cluster-level operations (e.g., storage and compute resource allocation). The database administrator needs appropriate Prism Element roles (e.g., Cluster Admin) to interact with the underlying infrastructure, even if the software profile is available in NDB. Without these permissions, the provisioning action will fail.

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 starving, the administrator wants to differentiate VM resources for each department. What is the most efficient way to accomplish this task?
A. Use a VM Template for each department.
B. Create multiple Compute profiles.
C. Leverage NCM Self Service to deploy database clones.
D. Generate a playbook to resize database VMs when released.
正解：B
解説：
An administrator needs to provision multiple database clones from the same source database for different purposes (e.g., QA and Test/Development) while avoiding resource starvation by differentiating VM resources for each department. The most efficient way to achieve this is by creating multiple Compute profiles in NDB. Compute profiles define CPU, memory, and other resource allocations for VMs, allowing the administrator to tailor resource limits (e.g., higher resources for QA, lower for Development) and apply them during clone provisioning. This approach is built into NDB, ensuring consistent resource management without manual adjustments.

An administrator needs to create a custom PostgreSQL HA software profile. Which software component manages the state of the cluster and handles failover?
A. etcd
B. HAProxy
C. Patroni
D. keepa lived
正解：C
解説：
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.
質問 # 220
An administrator needs to work with databases and time machines, but not database parameter profiles. Which role satisfies this requirement?
A. Database Administrator (DBA)
B. Database Infrastructure Administrator
C. super Administrator
D. Infrastructure Administrator
正解：A
解説：
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). 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 roles.
