Nutanix Certified Professional - Database Automation v6.10 NCP-DB Exam Practice Test

Answer : C

In an NDB high availability (HA) environment spanning multiple Nutanix clusters, with two clusters running VMware ESXi and one running Nutanix AHV, cross-hypervisor compatibility becomes essential to manage the heterogeneous environment effectively. Nutanix Prism Central is the centralized management platform that provides a unified interface and orchestration capabilities across multiple clusters, regardless of the underlying hypervisor (ESXi or AHV). For NDB HA to function seamlessly across these clusters, Prism Central is required to coordinate cluster operations, manage resources, and ensure consistent policy enforcement, including VM placement, failover, and database management tasks. It abstracts the differences between hypervisors, enabling NDB to operate in a mixed environment.

Option A (Stretched VLANs for all nodes) is incorrect because stretched VLANs address network connectivity, not hypervisor compatibility or NDB HA management.

Option B (NGT - Nutanix Guest Tools) is incorrect as NGT enhances guest VM functionality (e.g., drivers, backups) but does not facilitate cross-hypervisor orchestration for NDB HA.

Option C (Nutanix Prism Central) is correct because it provides the necessary multi-cluster management and compatibility layer for NDB HA across ESXi and AHV.

Option D (VirtlO) is incorrect as VirtIO refers to paravirtualized drivers for VMs, not a component for NDB HA or cross-hypervisor support.

Prism Central's role ensures that NDB can manage database workloads across diverse hypervisor platforms efficiently.

Answer : B

In Nutanix Database Automation (NCP-DB), the Database Parameters profile is used to manage database-specific settings, including the maximum number of database connections.This profile would be the appropriate choice when an administrator needs to change these settings during the cloning workflow1.

Answer : A

When an administrator changes the NDB language settings from English to Spanish, but the language reverts to English when accessing NDB from a different workstation, it indicates that the language settings are tied to the web browser on the original workstation rather than being globally applied. NDB's language settings are typically stored locally in the browser's cache or pReference:s (e.g., via cookies or browser locale settings), meaning they do not persist across different devices or browsers unless explicitly synchronized (e.g., via user profile settings, which NDB does not universally enforce).

Other options are incorrect:

B . The language settings match workstation regional settings: This would depend on the OS locale, not the observed behavior of reverting to English.

C . The language settings revert to English after logoff: NDB does not reset language settings upon logoff; the issue is device-specific.

D . The language settings are bound to NDB users: If this were true, the language would persist across workstations for the same user, which is not the case here.

Thus, the verified answer is A, reflecting browser-local language management.

Answer : A

A 'dark site' refers to an environment with no internet connectivity, requiring manual processes for software updates. For Nutanix Database Service (NDB) in such a setup, updates cannot be downloaded automatically from the internet. The correct procedure is to:

Download the upgrade bundle: Access the Nutanix Support Portal from a system with internet access and download the NDB upgrade bundle specific to the version (e.g., v6.10 or later).

Manually upload it to the NDB server: Transfer the bundle to the NDB server (e.g., via SCP or USB) and upload it through the NDB interface under the 'Software Updates' or 'Maintenance' section.

Other options are incorrect in a dark site context:

B: The 'Administrator > Maintenance' section allows initiating updates, but it cannot download files without internet access.

C: Changing the network to access https://download.nutanix.com defeats the dark site's isolation and is impractical.

D: Uploading to Prism Element > Images is for VM images or other Prism-specific content, not NDB software updates.

Thus, the verified answer is A, aligning with Nutanix's documented process for dark site updates.

Answer : B

To apply the latest OS security patches on a Windows server managed by NDB, the user should create and apply a Maintenance Plan within the NDB interface. NDB provides a Maintenance Plan feature that allows administrators to schedule and automate OS patching for database server VMs, ensuring patches are applied in a controlled manner without disrupting database operations. This includes validating the patch process, rolling back if needed, and maintaining compliance with security standards. The plan can be configured to target the specific Windows server and include the latest security updates from Microsoft.

Other options are incorrect or insufficient:

A . Reboot the system: A reboot alone does not apply patches; it may only activate previously installed updates.

C . Update the database: This focuses on database software, not OS security patches.

D . Use update functionality directly on the VM: Manual updates bypass NDB's control, risking inconsistency and potential downtime without proper validation.

Thus, the verified answer is B, leveraging NDB's centralized maintenance capabilities.

Answer : B

When a database is de-registered from NDB without removing the associated Time Machine, the Time Machine enters a 'Frozen' state. In this state, the Time Machine retains all existing snapshots and protection data but ceases to perform new snapshot captures or log catch-up operations. This allows the administrator to preserve the historical data for potential future use (e.g., auditing or recovery) while halting active management. The Frozen state prevents further modifications until the database is re-registered or the Time Machine is explicitly deleted.

Option A (Ready) is incorrect because 'Ready' implies the Time Machine is active and prepared for new operations, which is not the case post-de-registration.

Option B (Frozen) is correct as it reflects the paused protection state after de-registration without removal.

Option C (Paused) is incorrect because 'Paused' is not a formal Time Machine state in NDB; 'Frozen' is the specific term.

Option D (Active) is incorrect because the Time Machine cannot remain active without an associated registered database.

This state provides flexibility for data retention without ongoing resource use.

Answer : B

In Nutanix Database Service (NDB), a Network Profile is used to define networking configurations for database VMs, including VLAN assignments and IP address ranges. The correct procedure to create a Network Profile that assigns a VLAN and provides IP addresses to a database VM is as follows:

Create Network Profile: Start by initiating the creation of a new Network Profile within NDB. This is done from the NDB interface under the 'Network' or 'Profiles' section.

Select the VLAN: During the Network Profile creation process, you specify the VLAN that the database VM will use. This involves selecting an existing VLAN configured in the Nutanix cluster (e.g., via Prism Element) or defining a new VLAN ID if applicable.

Define IP Range: Finally, you define the IP address range (e.g., a subnet or specific IPs) that will be assigned to the database VM(s) within the selected VLAN. This ensures the VM receives a valid IP address for communication.

The sequence in option B aligns with the NDB workflow, where the Network Profile is created first, followed by associating it with a VLAN and then defining the IP allocation. Other options are incorrect:

A: 'Add the VLAN' is vague and does not specify where the VLAN is added, disrupting the logical flow.

C: Adding a VLAN before creating the profile is not the standard NDB process, as VLANs are associated during profile creation.

D: Defining an IP range before creating the profile is out of sequence, as the profile must exist to hold the configuration.

Thus, the verified answer is B. Create Network Profile, Select the VLAN, Define IP Range.
