New Release NCP-DB Nutanix Certified Professional (NCP) Questions

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Option D (Software profile is not published) is incorrect because an unpublished software profile might limit availability to users, but the Update button’s presence relies on VM connectivity, not profile publication status.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

Option A: On the Era Dashboard Database Summary Table under Source Database. The dashboard provides a summary of the databases, including their sizes1.

Option B: Under the Capacity widget on the Database Server VMS > List database summary page. While this might provide information about the capacity, it does not specifically provide the size of a Source Database.

Option C: On the Databases > Sources table. This table provides detailed information about the databases, including their sizes1.

Option D: On the Profiles > Database Parameters list for the assigned DB Parameter Profile. This list provides parameters for the database but does not provide the size of a Source Database.

To create a software profile version for a newly-released Oracle ISc patch, an administrator should follow these steps:

Download the required patch from MyOracle Support1. This is because Oracle patches are typically available from MyOracle Support, not Microsoft Support.

Apply the patch to the Oracle Home/Grid Home on a cloned VM of the gold image using OPatchAuto1. OPatchAuto is a utility provided by Oracle that automates the process of applying patches to a database.

Ensure success of patch application1. It’s important to verify that the patch has been applied successfully to avoid any issues down the line.

Create a new software profile version from the original software profile using the cloned VM where OPatchAuto was run successfully using Era GUI1. This step is necessary to ensure that the new patch is included in the software profile.

Mark the original patch profile as hidden1. This step is optional but can be useful for keeping the software profile clean and organized.

Please note that these answers are based on the information available as of my last update in 2021 and may need to be verified with the most recent Nutanix Database Automation (NCP-DB) documentation or resources.

To add Time Machine data access to a Nutanix cluster, the first step is to register the cluster in NDB. This will allow NDB to discover and manage the databases and snapshots on the cluster. You can register multiple Nutanix clusters in NDB using the Add Cluster option in the NDB settings page. You can also specify the cluster role, such as source, target, or both, depending on the data access and replication needs. Enabling or disabling multi-cluster in NDB is not the first step, as this is a global setting that affects the entire NDB instance. Deleting the TM data from the source database is not the first step, as this will remove the data protection and availability of the database. References:
