NEW QUESTION # 94
An administrator needs to make new VLANs available when provisioning a Oracle cluster database, which have been added to NDB via the Administration menu. What needs to be done to expose the new VLANs for provisioning?
- A. Create a new Network Profile with the new VLANs.
- B. Update the Network Profile to include the new VLANs.
- C. Create a new VLAN in Prism Element and discover it in NDB.
- D. Update Prism Element with the new VLAN and discover it in NDB.
Answer: B
Explanation:
A Network Profile is a collection of network settings that are used to provision database server VMs in NDB. A Network Profile can include one or more VLANs, IP ranges, and DNS servers. To make new VLANs available when provisioning an Oracle cluster database, you need to update the Network Profile to include the new VLANs. You can do this by editing the existing Network Profile or creating a new one with the new VLANs. You do not need to create or update the VLANs in Prism Element, as NDB can discover the VLANs configured in AHV.

The insights.nutanix.com site is the designated endpoint for telemetry data, which includes usage statistics, health metrics, and other operational data sent to Nutanix for support and analytics purposes. This connectivity is a standard requirement for NDB to comply with Nutanix's telemetry and support framework, and port 443 is used for secure transmission.
NEW QUESTION # 101
Which policies define Time Machine data availability across multiple registered clusters in NDB?
- A. Data Protection
- B. Service Level Agreements
- C. Data Access Management
- D. Recovery Plans
Answer: D
Explanation:
The recovery plans policy defines the Time Machine data availability across multiple registered clusters in NDB. The recovery plans policy allows the database administrator to specify the source and target clusters, the frequency and retention of the cross-cluster snapshots, and the network and compute profiles for the recovery operations. The recovery plans policy helps to ensure the disaster recovery and business continuity of the NDB-managed databases in case of a cluster failure or outage.
The data access management policy defines the access permissions and roles for the NDB users and groups. The data access management policy allows the database administrator to grant or revoke access to the NDB instance, the database server VMs, the databases, and the database operations. The data access management policy helps to ensure the security and compliance of the NDB- managed databases and users.
The data protection policy defines the backup and restore settings for the NDB-managed databases. The data protection policy allows the database administrator to specify the frequency, retention, and compression of the database snapshots, and the backup location and encryption for the database backups. The data protection policy helps to ensure the backup and recovery of the NDB-managed databases within the same cluster.
The service level agreements policy defines the performance and availability metrics for the NDB- managed databases. The service level agreements policy allows the database administrator to monitor and enforce the database uptime, latency, throughput, and IOPS. The service level agreements policy helps to ensure the quality of service and performance of the NDB-managed databases.
NEW QUESTION # 102
An administrator begins an SQL database clone deletion, but notices it fails almost immediately.
What could be the cause of this failure?
- A. The database data drives are shared with other applications.
- B. A refresh operation is in progress.
- C. The database was not marked as Offline before the operation.
- D. The clone has been marked as Immutable.
Answer: D
Explanation:
If an SQL database clone deletion fails immediately in NDB, the most likely cause is that the clone has been marked as Immutable. An immutable clone is protected from deletion to prevent accidental data loss, often set for critical development or testing environments. This protection must be explicitly removed by the administrator (e.g., via the NDB GUI or CLI) before the deletion can proceed.

- A. path=path_to_upgrade_bundle upgrade bundle
- B. path=path_to_upgrade_bundle
- C. upgrade upload_bundle path=path_to_upgrade_bundle upload bundle
- D. upload upgrade_bundle path=path_to_upgrade_bundle
Answer: D
Explanation:
For an NDB offline upgrade, you need to download the upgrade bundle from the Nutanix Support Portal and copy it to the NDB server. Then, you need to use the NDB CLI command upload upgrade_bundle with the path parameter to specify the location of the upgrade bundle file. This command will upload the upgrade bundle to the NDB server and verify its integrity. After uploading the upgrade bundle, you can use the upgrade command to perform the upgrade.
NEW QUESTION # 105
A DBA team needs to release PostgreSQL HA instances using a dedicated subnet. Which action is mandatory before creating the network profile?
- A. A VLAN must be added to NDB networks.
- B. The subnet in Prism Element must be iPAM configured.
- C. The DB VMs must be registered first.
- D. Configure Network Segmentation.
Answer: A
Explanation:
To release PostgreSQL HA instances using a dedicated subnet in Nutanix Database Service (NDB), the administrator must create a network profile that defines the subnet and its associated VLAN. Before creating this network profile, it is mandatory to add a VLAN to the NDB Networks configuration. This VLAN ensures that the dedicated subnet is recognized and manageable within NDB, allowing the HA instances to be provisioned with isolated network connectivity. The VLAN must be configured in the NDB Networks page to be available for selection during network profile creation.
NEW QUESTION # 106
How would an administrator enter the NDB command line to change the static IP address on the NDB VM?
- A. era
- B. era-server
- C. cerebro_cli
- D. arithmos cli
Answer: C
Explanation:
To change the static IP address on the NDB VM, an administrator would need to enter the NDB command line using the cerebro_cli command. The cerebro_cli command is used to access the Cerebro service, which is responsible for managing the NDB instance and its components. The cerebro_cli command can be run from the NDB VM or from any other VM that has network connectivity to the NDB VM. The cerebro_cli command has various subcommands and options to perform different tasks, such as changing the IP address, hostname, password, or certificate of the NDB VM. To change the static IP address, the administrator would need to use the cerebro_cli network update subcommand with the appropriate parameters, such as the new IP address, netmask, gateway, and DNS servers. The cerebro_cli network update subcommand also requires the administrator to provide the current password of the NDB VM for authentication.
After changing the IP address, the administrator would need to restart the NDB VM for the changes to take effect.
NEW QUESTION # 107
When trying to restore a database via Time Machine (TM), the option to restore data to a Point in Time is not available.
What should the administrator do to enable Point in Time Recovery?
- A. Use Brass SLA & update the Log catch up frequency.
- B. Take a Manual snapshot and use it for DB recovery.
- C. Use an SLA that supports Continuous Log retention.
- D. Update the TM schedule to perform DB Log catch up.
Answer: C
Explanation:
Point in Time Recovery (PITR) is a feature of NDB that allows restoring a database to any point in time within the retention period of the SLA. To enable PITR, the SLA must support Continuous Log retention, which means that NDB captures and stores the database logs continuously. This allows NDB to replay the logs from the last snapshot to the desired point in time during the restore process. The other options do not enable PITR, but rather affect the frequency and timing of the snapshots and log catch up operations.
NEW QUESTION # 108
A developer requests a new development database environment. The Era administrator identifies that there are insufficient resources on the development cluster.
Which two profiles should the administrator adjust to get the copy to fit within the resources available? (Choose two.)
- A. Compute
- B. Network
- C. Database Parameters
- D. Sofware
Answer: A,C
Explanation:
In the context of Nutanix Database Automation (NCP-DB), when there are insufficient resources on a development cluster, the administrator can adjust the Compute and Database Parameters profiles to make the copy fit within the available resources. The Compute profile includes settings related to CPU and memory resources, which can be adjusted to fit within the available resources. The Database Parameters profile includes settings that control the behavior and resource usage of the database, which can also be adjusted to optimize resource usage.
NEW QUESTION # 109
An administrator changed NDB language settings from English to Spanish, but when accessing NDB from a different workstation the language reverts to English.
Which statement describe the matter?
- A. The language settings are bound to NDB users.
- B. The language settings are local to the web browser.
- C. The language settings match workstation regional settings.
- D. The language settings revert to English after logoff.
Answer: B
Explanation:
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).
NEW QUESTION # 110
An administrator needs the ability to clone a source database to a point in time. What is the lowest log frequency in minutes that can be configured in the Era IJI for log catchup operation?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: B
Explanation:
The log frequency in the Era IJI for log catchup operation can be configured to as low as 5 minutes. This allows the system to capture changes to the database at a high frequency, enabling more precise point-in-time recovery options. However, it's important to note that a higher frequency of log catchup operations can lead to increased system load. Therefore, the optimal frequency may vary depending on the specific requirements and capabilities of your system.
Please refer to the Nutanix Database Automation (NCP-DB) Learning documents for more detailed information.

- A. Notes
- B. Tags
- C. Index
- D. Text
Answer: B
Explanation:
Nutanix Era allows custom metadata to be assigned to entities (clones, time machines, databases, and database servers) by using Tags. Tags are a component of Nutanix Era that allows users to assign custom metadata to various entities, enhancing the ability to organize, search, and manage these entities within the Era platform.
NEW QUESTION # 112
What is required to cre110ate a network profile in Era?
- A. The network must be managed by Era.
- B. The network must contain static IP addresses.
- C. The network must be added to Era.
- D. The network must provide IP address management.
Answer: C
Explanation:
According to the Nutanix Database Automation (NCP-DB) learning documents, to create a network profile in Era, the network must be added to Era. This is because Era needs to have control over the network in order to manage the databases effectively. Once the network is added to Era, it can be used for various operations such as provisioning new databases, managing existing databases, and more.
NEW QUESTION # 113
Which port should be opened to ensure the NDB server, NDB agent, and NDB database agent can communicate with the registered cluster via REST API calls?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
To ensure the NDB server, NDB agent, and NDB database agent can communicate with the registered cluster via REST API calls, port 2009 must be opened. This port is used by NDB components to facilitate RESTful communication with the Nutanix cluster (e.g., Prism Element or Prism Central) for operations such as provisioning, monitoring, and management. Proper firewall configuration to allow traffic on this port is a prerequisite for NDB's integration with the cluster.
NEW QUESTION # 114
How should a patch be downloaded to perform a One-Click Upgrade of an NDB Environment with access to the Internet?
- A. Open Prism Central and deploy the current version of NDB from the Apps and Marketplace section.
- B. Open Prism Element and use LCM to update the software.
- C. Download the patch from the Nutanix Support Portal and upload via the NDB CLI.
- D. Download the patch in the Administrator > Maintenance section of NDB.
Answer: D
Explanation:
For a One-Click Upgrade of an NDB environment with internet access, the patch should be downloaded directly within the NDB interface. The "Administrator > Maintenance" section of NDB provides an option to connect to the Nutanix download repository (e.g.,
https://download.nutanix.com) and download the latest patch or upgrade bundle automatically.
This streamlined process ensures compatibility and simplifies the upgrade workflow. The One- Click Upgrade feature then applies the downloaded patch to update NDB components efficiently.
NEW QUESTION # 115
When an Oracle database is upgraded using Era, what is the type of upgrade category?
- A. In-place upgrade
- B. Non-disruptive upgrade
- C. Disruptive upg raze
- D. Out-of-place upgrade
Answer: A
Explanation:
When an Oracle database is upgraded using Era, the type of upgrade category is an "In-place upgrade". This method involves upgrading the database software within the same Oracle home as the existing database. The AutoUpgrade utility is used to automate the upgrade process, both before starting upgrades, during upgrade deployments, and during post-upgrade checks and configuration migration. This method is preferred due to its simplicity and efficiency.
NEW QUESTION # 116
Which response shows two ways to upgrade an NDB Server?
- A. One-click Upgrade and In-place Upgrade Auto
- B. Upgrade and Manual Upgrade
- C. One-click Upgrade and Offline Upgrade
- D. Out-of-Place Upgrade and In-place Upgrade
Answer: C
Explanation:
There are two ways to upgrade an NDB Server: one-click upgrade and offline upgrade. One-click upgrade is the recommended method, as it automatically downloads and installs the latest NDB software version from the Nutanix portal. Offline upgrade is an alternative method, which requires you to manually download the NDB software bundle and upload it to the NDB Server VM. Both methods require you to have a valid Nutanix account and an internet connection.
NEW QUESTION # 117
While adding Time Machine data access to a Nutanix cluster, when is a storage container mapping needed?
- A. When the source database and NDB VM are on the same container.
- B. When the source database and NDB Server containers are different.
- C. When the source and destination database containers are different.
- D. When the source database and NDB provisioning container are the same.
Answer: B
Explanation:
Time Machine data access is a feature of Nutanix Database Service (NDB) that allows you to access a point-in-time snapshot of a database without restoring it. To use this feature, you need to create a Data Access Management (DAM) policy that defines the access mode, the source database, the destination cluster, and the storage container mapping. The storage container mapping is needed when the source database and the NDB Server containers are different, because NDB needs to know where to store the metadata and the clone of the source database.
If the source database and the NDB Server containers are the same, then NDB will use the same container for both the metadata and the clone.
