NCP-DB Exam Dumps - Nutanix Certified Professional - Database Automation (NCP-DB v6.10)

When an administrator cannot proceed with the first step of the wizard to provision a new Oracle single instance database in NDB, the most likely reason is that a software profile for Oracle is missing. NDB requires a software profile (which defines the database version, patches, and configuration) to provision a database instance. Without a profile created from a reference VM or uploaded manually, the wizard cannot proceed, as it relies on this profile to configure the instance correctly.

Option A (Time Machine is not configured) is incorrect because Time Machine is optional for backups and not required for initial provisioning.

Option B (Software profile is missing) is correct as it is a mandatory prerequisite for provisioning any database instance.

Option C (No remote clusters are configured) is incorrect because remote clusters are relevant for multi-cluster setups, not single instance provisioning.

Option D (A snapshot must be taken on the original DB) is incorrect because snapshots are for protection, not a prerequisite for provisioning.

The administrator must create or import a software profile to resolve this issue.

To allow a non-administrative NDB user to provision an Oracle database using a Software Profile created by an administrator, the administrator must promote the Software Profile to Published. In NDB, Software Profiles define the database software version and configuration (e.g., Oracle binaries). By default, a newly created profile is in a draft or private state. Promoting it to "Published" makes it available for use by other NDB users, including non-administrative ones, within the access control framework. This ensures the profile is validated and accessible without requiring individual user assignments.

Other options are incorrect:

A. Ensure that specified users have access to the Software Profile using Access Control: Access Control manages user permissions but does not make the profile available unless it is published.

B. Replicate the Software Profile to other Nutanix clusters: Replication is for HA or disaster recovery, not user access.

C. Ensure that the Software Profile has been properly versioned to the latest release of Oracle: Versioning ensures compatibility but does not grant user access.

Thus, the verified answer is D, aligning with NDB’s profile management workflow.

In the context of Nutanix Era, the term “Brownfield Database” is used to refer to an existing database that is registered with Era1. This process allows Era to bring Database as a Service (DBaaS) capabilities to your existing database2. It’s important to note that before you register a database with Era, certain prerequisites must be met3.

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:

Time Machine is a feature of Nutanix Era that allows you to create and manage snapshots of your databases. You can use Time Machine to create clones from any snapshot, either manually or automatically. You can also configure Time Machine to create clones from snapshots based on a schedule, such as daily, weekly, or monthly. This way, you can ensure that your clones are always up to date with the latest data from your production databases. In this scenario, the most efficient way to meet the developer’s requirement is to configure Time Machine to create a clone from a daily snapshot at 7:00am. This will save the developer’s time and effort, as well as reduce the storage consumption by using the existing snapshots. References:

Nutanix Era offers Role-Based Access Control capabilities by organically embedding them in the product. It provides the ability to add and remove users from Era, create and assign roles to users, and associate various privileges with a role1. The default roles available within Era for Role-Based Access Control are:

prism Admin

Era Super Admin

Era Database Admin

Era Infrastructure Admin1 These roles allow for the management of both physical resources like IP addresses and VLANs along with database entities like databases, time-machines, clones, and so on1.

Nutanix Database Service (NDB) uses software profiles for database patching to keep your databases secure and optimized1. When a new database is provisioned, it will be on your current environment’s database version to maintain consistency and stop version sprawl1. Therefore, after an administrator has applied an Oracle security patch to a database server VM registered in Era, the change can be made available to other existing database instances by creating a new software profile in Era from the patched VM1.

To assign the minimum permissions required for provisioning new databases in an NDB deployment, the IT manager should assign the Database Administrator role. This role provides the necessary privileges to provision, configure, and manage database instances within NDB, including creating new databases using software profiles and registering database servers. It is designed for database-specific tasks without granting broader infrastructure or administrative control, making it the least privileged role suited for this purpose.

Other options exceed the minimum requirements:

A. Infrastructure Administrator: Manages cluster infrastructure (e.g., storage, networking), which is more than needed for database provisioning.

B. Super Administrator: Grants full control over NDB, including user management and system configuration, far beyond provisioning.

C. Database Infrastructure Administrator: Includes infrastructure management in addition to database tasks, exceeding the minimum scope.

Thus, the verified answer is D, aligning with the principle of least privilege.
