Nutanix Certified Professional (NCP) NCP-DB Exam Questions and Answers PDF

An administrator needs to provision multiple database clones from the same source database for different purposes (e.g., QA and Test/Development) while avoiding resource starvation by differentiating VM resources for each department. The most efficient way to achieve this is by creating multiple Compute profiles in NDB. Compute profiles define CPU, memory, and other resource allocations for VMs, allowing the administrator to tailor resource limits (e.g., higher resources for QA, lower for Development) and apply them during clone provisioning. This approach is built into NDB, ensuring consistent resource management without manual adjustments.

Option A (Create multiple Compute profiles) is correct as it provides a scalable and efficient way to allocate resources per department.

Option B (Leverage NCM Self Service to deploy database clones) is incorrect because Nutanix Cluster Management (NCM) Self Service is for end-user provisioning, not resource differentiation.

Option C (Use a VM Template for each department) is incorrect because VM templates are less flexible and not natively integrated with NDB clone provisioning.

Option D (Generate a playbook to resize database VMs when released) is incorrect because playbooks are for automation, not initial resource allocation, and resizing post-provisioning is less efficient.

This method optimizes resource use across departments.

For supported Linux-based database VMs managed by NDB, keeping software profiles updated for provisioning new database VMs requires a structured process. The administrator must first apply the necessary patches (e.g., OS updates and database engine patches) to an existing database VM for each supported database engine (e.g., PostgreSQL, Oracle). Then, a new software profile version must be created using the updated VM as the source. This new version captures the patched configuration and can be used to provision new VMs, ensuring they are deployed with the latest updates.

Option A (Create a Maintenance window under the policy menu, then under Database VM, add the database VMs to that maintenance window and check both Database and Operating system updates) is incorrect because a Maintenance Window schedules updates for existing VMs, not for updating software profiles for new provisions.

Option B (Apply patches to a database VM for each supported database engine, then create a new software profile version for each supported database VM for each one using the updated database VM as the source) is correct as it follows the standard NDB process for profile updates.

Option C (Associate the newly provisioned database VMs with a maintenance window so they are kept updated) is incorrect because this applies to ongoing maintenance, not initial profile updates for provisioning.

Option D (In the Administrator menu drop down, go the Maintenance tab and choose Download Upgrade) is incorrect because downloading upgrades is part of the patch process, not the profile creation step.

This method ensures new VMs are provisioned with the latest software configurations.

When an administrator encounters an error provisioning a new Oracle database VM in NDB, the best action to provide Nutanix support with the most complete picture is to select the failed job in the Operations menu and choose Generate Bundle from the lower right. The "Generate Bundle" option creates a comprehensive diagnostic package, including logs, configuration details, and error traces specific to the failed operation. This bundle is ideal for troubleshooting and can be uploaded to Nutanix Support for analysis.

Other options are less comprehensive:

A. From the Administration section of NDB, go to the Diagnostics section and choose Generate Bundle: This generates a general diagnostic bundle, not specific to the failed job.

B. Copy the error message from the Operations menu: This provides limited context compared to a full bundle.

D. Take a screenshot of the error in the Operations menu: A screenshot lacks detailed logs and system data needed for support.

Thus, the verified answer is C, ensuring detailed support data.

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.
