Nutanix NCP-DB Practice Questions

D.   Administration > Maintenance

Explanation:
In the Nutanix Era management interface, an administrator should perform an upgrade under the Administration > Maintenance section1. As part of the upgrade process, the Era server is upgraded first, followed by all the Era cluster agents and database server agents in parallel1. The Dashboard displays the current version and an option to upgrade the Era server to a latest version when a new version is available for upgrade1. This ensures that the Nutanix Era environment is always up-to-date with the latest features and security updates1.

C.   Restore using point in time till 10:42pm.

Explanation:
The optimal path to restore the table back with minimum data loss is to use the point in time restore feature of NDB, which allows the administrator to restore the database to a specific point in time based on the available snapshots and logs1. By restoring using point in time till 10:42pm, the administrator can recover the table just before it was dropped by the user, and minimize the data loss to the least possible amount1. The other options are not optimal, as they either involve restoring an older snapshot, which may result in more data loss, or restoring a non-existent snapshot, which is not possible.

B.   Compute

D.   Storage

Explanation:
In the Nutanix Database Automation (NCP-DB) framework, provisioning a new Oracle database through Era requires the configuration of both a Compute and a Storage profile1. The Compute profile is used to define the resources allocated to the database, such as CPU and memory, while the Storage profile is used to specify the storage configuration for the database. These profiles are essential in ensuring that the database is provisioned with the necessary resources and storage configurations for optimal performance23.

B.   Era patching can be automated using REST API/CLI for scheduled patching many Oracle servers in a fleet patching scenario,

C.   Era patching for Oracle databases has automatic rollback if any of the steps in the patching workflow fails.

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.

A.   NDB supports alert retention globally.

Explanation:
The NDB alert retention feature allows the database administrator to configure the duration for which the NDB alerts are stored and displayed in the NDB instance. The NDB alert retention feature supports alert retention globally, meaning that the same retention period applies to all the alerts generated by the NDB instance, regardless of the source cluster, policy, or operation. The database administrator can set the alert retention period from 1 day to 365 days, or choose to retain the alerts indefinitely. The NDB alert retention feature helps to manage the storage space and the visibility of the NDB alerts.
The NDB alert retention feature does not support retention at the individual policy, grouped policy, or registered cluster level. The NDB alert retention feature applies to all the alerts uniformly, and does not allow the database administrator to specify different retention periods for different policies or clusters.

C.   Infrastructure administrator

Explanation:
In Nutanix Era, the ability to add a new VLAN or IP Pool is typically associated with the role of an Infrastructure Administrator12. This role has the necessary permissions to manage network configurations, including the creation of VLANs and IP Pools12. It’s important to note that the exact permissions may vary depending on the specific configuration and policies of your organization12.
