An administrator needs to roll back an Oracle patch on a database server VM using NDB. What is required for this action to be successful?
Answer(s): A
To roll back an Oracle patch on a database server VM using NDB, the patch must have been applied using NDB in the first place. This is because NDB maintains a patch inventory and history for each database server VM and database that it manages. NDB uses this information to determine which patches can be rolled back and how to revert the changes made by the patch. If the patch was applied outside of NDB, NDB would not have the patch information and would not be able to roll back the patch. Therefore, the patch must have been applied using NDB for the rollback action to be successful. The other options are not required for the rollback action. The database does not need to be shut down or in read-only mode, as NDB can perform the rollback operation online. The patch does not need to be applied on Grid home only, as NDB can roll back patches applied on both Grid home and Database home.

Which ports must be open between the NDB server and Controller VMs to facilitate iSCSI connections?
Answer(s): C
According to the Nutanix Database Automation (NCP-DB) course, the ports 3205 and 3260 are required for iSCSI connections between the NDB server and the Controller VMs1. Port 3205 is used for the NDB iSCSI initiator service, which initiates the iSCSI sessions and sends SCSI commands to the Controller VMs1. Port 3260 is used for the iSCSI target service, which listens for incoming iSCSIrequests and provides access to the storage devices on the Controller VMs1. The other options are not related to iSCSI connections. Port 22 is used for SSH, port 9440 is used for Prism Central, port 80 is used for HTTP, port 443 is used for HTTPS, port 5985 is used for WinRM HTTP, and port 5986 is used for WinRM HTTPS2.

An administrator needs to distribute NDB management plane components.Which NDB HA VM needs to be deployed on the same L2 network?
Answer(s): D
NDB High Availability (HA) is a feature that ensures the availability and reliability of the NDB management plane components, such as the API Server, the Repository VMs, and the NDB Agents. To enable NDB HA, you need to deploy at least three HA Proxy VMs on the same L2 network as the NDB Server VM. The HA Proxy VMs act as load balancers and health monitors for the NDB management plane components, and they also provide a single endpoint for accessing the NDB APIs and UI.

What step should be taken to make the profile available to all users:
The correct answer is D because it allows the administrator to make the profile available to all users without requiring any additional permissions or roles. A profile is a collection of settings that define how NDB manages a database server or a database. By default, a profile is only available to the user who created it and the Database Admin role. To make a profile available to all users, the administrator can update the profile and set the available state to All. This will enable all users to view and use the profile for their database operations. The other options are not correct because they either require additional steps or do not achieve the desired outcome. Option A is not correct because creating an Access Control role with the Create Profile right and assigning it to all users will only allow them to create their own profiles, not use the existing one. Option B is not correct because creating an Access Control group with the desired users and granting it the Database Admin role will only make the profile available to those users, not all users. Option C is not correct because updating the profile and setting the status to Published will not change the availability of the profile, only the state of the profile. A published profile is a profile that has been tested and verified by the administrator and is ready for use. A draft profile is a profile that is still under development or testing and is not ready for use.
