NCP-DB Exam Dumps : Nutanix Certified Professional - Database Automation (NCP-DB) v6.5

NDB sends notifications when alerts are generated via email. The email notifications can be configured to send to one or more recipients, and can be customized to include the alert severity, category, description, and resolution steps. The email notifications help to inform the database administrator and other stakeholders about the status and issues of the NDB-managed databases and operations.

NDB does not send notifications via SNMP, APIs, or Pulse. SNMP is a protocol for collecting and organizing information about managed devices on a network. APIs are interfaces for communicating and exchanging data between different applications or systems. Pulse is a feature of the Nutanix cluster that collects and sends diagnostic and usage data to Nutanix for analysis and support.

 To increase storage for a MongoDB database provisioned using NDB, the administrator needs to use the extend_storage parameter in the input file for the NDB CLI. This parameter specifies the amount of additional storage to be added to the database server VM in GB. For example, if the current storage size is 100 GB and the administrator wants to increase it to 150 GB, the input file should contain the following line:

extend_storage: 50

The other parameters are not relevant for this operation. The update parameter is used to update the database software version, the database parameter is used to specify the database name, and the data_percent parameter is used to specify the percentage of data to be copied during a clone operation. References: Nutanix Database Automation (NCP-DB) Course Details, Nutanix Database Automation (NCP-DB) Certification Details, Nutanix Database Automation (NCP-DB) YouTube Playlist, [Nutanix Database Automation User Guide].

Time Machine data access is a feature of Nutanix Database Service (NDB) that allows you to access a point-in-time snapshot of a database without restoring it. To use this feature, you need to create a Data Access Management (DAM) policy that defines the access mode, the source database, the destination cluster, and the storage container mapping. The storage container mapping is needed when the source database and the NDB Server containers are different, because NDB needs to know where to store the metadata and the clone of the source database. If the source database and the NDB Server containers are the same, then NDB will use the same container for both the metadata and the clone. References:
