NCP-DB Reviews Questions

• Option A: Nutanix Era requires network prerequisites like NTP, DNS servers, gateway, and subnet mask to be available and visible. These are essential for the proper functioning of the Era instance1.
• Option B: One static IP address must be available and can be changed using CLI after VM deployment. This is necessary for the Era VM to communicate with other components in the network1.
• Option C: While a storage container is necessary for Nutanix infrastructure, it is not a network prerequisite specifically for deploying an Era instance.
• Option D: An SMTP server and details are typically used for sending notifications, but they are not a network prerequisite for deploying an Era instance. They are more related to the operational aspect post-deployment.

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.

Before updating Oracle Database software, you need to download the Patch Set Update (PSU) from Oracle support. A PSU is a collection of critical and security patches for Oracle products. You need to have a valid Oracle account and access to the My Oracle Support portal to download the PSU. You also need to check the compatibility and prerequisites of the PSU before applying it to your Oracle Database software. NDB uses out-of-place patching for Oracle, which means you need to create a new software profile version with the patched Oracle software and use it to update your existing databases. References:

According to the Nutanix Database Automation (NCP-DB) course, a Software Profile is a template that defines the configuration of the database engine, such as the version, edition, features, and parameters1. It also specifies the disk layout for the database installation, such as the size, type, and mount point of each disk1. However, the System Page File disk is omitted from the Software Profile, as it is automatically created by the NDB service based on the memory size of the database server VM1. The other options are included in the Software Profile, as they are essential for the database operation and performance1. References:
