Nutanix Certified Professional - Database Automation (NCP-DB) v6.5 Sample Questions (Q145-Q150):

NEW QUESTION # 145
An administrator originally configured the storage for an Oracle database running on Nutanix NDB using ASMLib. The administrator would like to scale the size of the database.
What should the administrator do to most efficiently increase the size of the database?

  • A. Leverage the scaling ability built into NDB to resize existing vDisks.
  • B. Mount an iSCSI LUN and extend the database onto the new LUN.
  • C. Create a new. larger database and migrate.
  • D. Extend the size by adding new vDisks.

Answer: A

Explanation:
When an administrator needs to scale the size of an Oracle database running on Nutanix NDB and originally configured using ASMLib (Automatic Storage Management Library), the most efficient approach is to use NDB's built-in scaling ability to resize existing vDisks. NDB supports dynamic resizing of virtual disks (vDisks) associated with database VMs, allowing the administrator to increase storage capacity without disrupting the database or requiring complex migrations. This method leverages Nutanix's storage integration, resizing the underlying vDisks and updating the ASMLib configuration to reflect the new size, ensuring seamless operation.
* Option A (Leverage the scaling ability built into NDB to resize existing vDisks) is correct as it is the most efficient, native NDB feature for scaling storage.
* Option B (Extend the size by adding new vDisks) is incorrect because adding new vDisks requires additional configuration (e.g., ASM disk group adjustments), making it less efficient than resizing.
* Option C (Create a new, larger database and migrate) is incorrect because migration is time- consuming and unnecessary when resizing is supported.
* Option D (Mount an iSCSI LUN and extend the database onto the new LUN) is incorrect because iSCSI LUNs are not the preferred method in NDB, and resizing vDisks is more integrated.
This approach minimizes downtime and complexity.

NEW QUESTION # 146
A clone needs to be created on an existing database server, but there are no Authorized database servers defined to support the cloned database.
In which two ways can Database Server VMs be authorized during a Clone Create operation? (Choose two.)

  • A. During the Clone creation process, click the plus icon to authorize one or more database server VMs.
  • B. During the database server provisioning process, flag the database server to be authorized for supporting cloned databases.
  • C. Within the Database Server VM Summary window, update the database sever to be authorized for supporting cloned databases.
  • D. Within Time Machine, use the Actions menu and Authorize Database Server VMs to identify which database server VMs to authorize for clones.

Answer: A,D

Explanation:
When creating a clone on an existing database server but no Authorized database servers are defined to support the cloned database, the administrator must authorize the necessary Database Server VMs. Two valid methods exist within NDB: (1) Using the Time Machine interface, the administrator can navigate to the Actions menu and select "Authorize Database Server VMs" to designate specific VMs for clone support, providing a proactive authorization step. (2) During the Clone creation process, the wizard includes an option (e.g., a plus icon) to authorize one or more database server VMs on the fly, streamlining the process if authorization is needed mid-operation.
* Option A (Within Time Machine, use the Actions menu and Authorize Database Server VMs to identify which database server VMs to authorize for clones) is correct as it is a dedicated authorization method in Time Machine.
* Option B (Within the Database Server VM Summary window, update the database server to be authorized for supporting cloned databases) is incorrect because the Summary window is for viewing, not authorizing, clone support.
* Option C (During the Clone creation process, click the plus icon to authorize one or more database server VMs) is correct as it allows real-time authorization during cloning.
* Option D (During the database server provisioning process, flag the database server to be authorized for supporting cloned databases) is incorrect because authorization is not typically set during initial provisioning but rather during clone operations.
These methods ensure the clone can be created on authorized servers.

NEW QUESTION # 147
Era allows custom metadata to be assigned to entities (clones, time machines, databases, and database servers) by using which component?

  • A. Text
  • B. Index
  • C. Tags
  • D. Notes

Answer: C

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 platform1.


NEW QUESTION # 148
An administrator needs to add multiple databases to an existing PostgreSQL instance.
How should the administrator satisfy this requirement?

  • A. Modify parameter profile using ncli.
  • B. Modify parameter profile using the GUI.
  • C. Modify parameter profile using post script.
  • D. Modify parameter profile using NDB CLI.

Answer: B

Explanation:
To add multiple databases to an existing PostgreSQL instance managed by NDB, the administrator should use the NDB graphical user interface (GUI). The GUI provides a user-friendly way to modify the parameter profile associated with the PostgreSQL instance, allowing the addition of new databases by adjusting settings such as database names, sizes, or configurations. This process typically involves navigating to the "Databases" or "Instances" section, selecting the PostgreSQL instance, and editing the parameter profile to include additional databases.
Other options are less appropriate:
* A. Modify parameter profile using ncli: The ncli (Nutanix Command Line Interface) is used for cluster-level management in Prism, not for NDB database configuration.
* C. Modify parameter profile using post script: Post-scripts are used for custom actions post- provisioning, not for modifying parameter profiles to add databases.
* D. Modify parameter profile using NDB CLI: While NDB has a CLI, the GUI is the recommended and supported method for such configuration changes, offering a guided workflow and validation.
Thus, the verified answer is B, leveraging the NDB GUI for ease and compliance with best practices.

NEW QUESTION # 149
When provisioning an PostgreSQL HA Instance, what are the minimum and maximum number of DB server VMs that can be deployed in a cluster?

  • A. Min 2, Max 4
  • B. Min 3, Max 5
  • C. Min 1. Max 3
  • D. Min 2, Max 6

Answer: A

Explanation:
When provisioning a PostgreSQL HA Instance using NDB, the minimum and maximum number of DB server VMs that can be deployed in a cluster are 2 and 4, respectively. A PostgreSQL HA Instance is a database instance that provides high availability and fault tolerance for PostgreSQL databases using the Patroni framework. Patroni is a Python-based tool that manages PostgreSQL configuration and performs automatic failover and switchover operations. Patroni relies on a distributed consensus store, such as etcd, Consul, or ZooKeeper, to store and synchronize the cluster state and leader information. NDB supports etcd as the consensus store for PostgreSQL HA Instances. NDB allows the administrator to provision PostgreSQL HA Instances with different sizes and configurations, such as small, medium, large, or custom. The size of the PostgreSQL HA Instance determines the number of DB server VMs, the number of etcd nodes, the CPU, memory, and disk resources, and the replication factor of the database. The minimum number of DB server VMs for a PostgreSQL HA Instance is 2, which corresponds to a small size instance. This configuration provides one leader and one follower DB server VM, and one etcd node. The maximum number of DB server VMs for a PostgreSQL HA Instance is 4, which corresponds to a large size instance. This configuration provides one leader and three follower DB server VMs, and three etcd nodes. The other options are not valid for a PostgreSQL HA Instance, as they either do not provide enough redundancy or exceed the supported limit of DB server VMs. References:
