Nutanix NCP-DB Exam With Confidence Using Practice Dumps

The command era-server > era server set ip=ip_address gateway=gateway_address netmask=ip_netmask nameserver=ns1 ntp_server=ntp1 is used to assign a static IP address to the NDB VM via the era-server CLI. This command requires core network parameters (ip, gateway, and netmask) to configure the VM’s network interface correctly. However, optional parameters like nameserver (DNS server) and ntp_server (Network Time Protocol server) can be omitted if the administrator relies on default or externally configured DNS and NTP settings (e.g., via DHCP or another management system). These optional parameters enhance functionality but are not mandatory for the basic static IP configuration.

Option A (ntp_server) is correct as it is optional and can be configured separately or omitted if NTP is managed externally.

Option B (netmask) is incorrect because the netmask is a required parameter to define the subnet for the IP address.

Option C (gateway) is incorrect because the gateway is a required parameter to specify the network route.

Option D (nameserver) is correct as it is optional and can be omitted if DNS is handled outside NDB.

Note: The typos in the question (gatevay_address, ip_J2etmas^c, narnesetver, ntpl) are assumed to be gateway_address, ip_netmask, nameserver, and ntp1 based on context.

In Nutanix Database Service (NDB), patching Oracle database engines requires the "Update" button to be available on the database server VM’s management interface. If this button is missing, it typically indicates a configuration issue preventing NDB from performing the patching operation. The most common and critical reason is that the operating system (OS) credentials for the database server VM have not been set or registered with NDB. These credentials are necessary for NDB to authenticate and execute patching tasks on the VM, such as accessing the Oracle software and applying updates via a software profile.

Option A is correct because missing OS credentials prevent NDB from establishing the required connection to the VM, disabling the Update button.

Option B (Database parameters are missing) is incorrect because while database parameters are important for configuration, they do not directly control the visibility of the Update button for patching.

Option C (Oracle DB engines cannot be patched) is incorrect as NDB explicitly supports patching Oracle databases when properly configured.

Option D (Software profile is not published) is incorrect because an unpublished software profile might limit availability to users, but the Update button’s presence relies on VM connectivity, not profile publication status.

To resolve this, the administrator must register valid OS credentials for the VM in NDB, enabling the patching functionality.

 Nutanix Era provides a unified database operating model that delivers simplicity, performance, availability, and security across private and public clouds1. It standardizes your Oracle database ecosystem by mass patching the databases with one-click simplicity2. This includes the following features:

Automated Patching: Era patching can be automated using REST API/CLI for scheduled patching many Oracle servers in a fleet patching scenario1. This allows for the standardization of your Oracle database ecosystem by mass patching the databases with one-click simplicity2.

Automatic Rollback: Era patching for Oracle databases has automatic rollback if any of the steps in the patching workflow fails1. This ensures that your databases remain secure and functional even if an issue arises during the patching process1.
