質問 # 283
A new administrator is tasked with changing the NDB GUI password via CLl.
Which command will accomplish this task?
正解：D
解説：
To change the NDB GUI password via the CLI, the administrator should use the command era-server > security password reset. This command interacts with the NDB server (referred to as era-server in the CLI context) to reset the password for the GUI admin user. The process typically prompts for the new password and confirmation, ensuring secure password management. This is the supported method for CLI-based password changes in NDB.
Other options are incorrect:
* A. sudo passwd era: The passwd command is for Linux user accounts, not NDB-specific GUI credentials.
* B. sudo user name admin password: This is not a valid command syntax for NDB CLI.
* C. era-server > username admin password: This lacks the correct subcommand (security password reset) and syntax.
Thus, the verified answer is D, aligning with NDB's CLI security management.

An NDB administrator is looking to free up some space consumption in the container that NDB uses to manage a database landscape.
Where are two of the best locations within NDB that the administrator could view to see where the most storage is being consumed, in order to research for reclamation? (Choose two.)
正解：B、D
解説：
To free up space in the NDB-managed container, the administrator needs to identify storage consumption sources. Two key locations in NDB provide actionable insights:
* C. Clone Database table: This displays all clone databases, including their Size (current storage usage) and Last Refresh (indicating age or staleness). Clones often consume significant space, and older or unused ones can be deleted to reclaim storage.
* D. Snapshot table in Time Machine: This shows snapshots with details like Reclaimable Space (space recoverable by deletion) and Age (how long snapshots have existed). Old or unnecessary snapshots are prime candidates for reclamation.
Why not the other options?
* A. NDB Dashboard (Clone Data Age): While it provides a high-level view, it lacks granular details (e.
g., size per clone) needed for targeted reclamation.
* B. Source Database grid: This shows registered databases' size and status but doesn't focus on derivative objects (clones/snapshots) that typically consume more space.
Thus, C and D are the best locations for detailed storage analysis and reclamation research.

質問 # 285
A new web application performs up to 200 concurrent connections to a PostgreSQL database. An administrator needs to configure the system to provision those DB servers.
Which action would easily help the administrator achieving this goal?
正解：A
解説：
A new web application with up to 200 concurrent connections to a PostgreSQL database requires a robust and scalable configuration. Provisioning a PostgreSQL HA (High Availability) instance in NDB is the most effective action to achieve this goal. An HA instance leverages replication (e.g., streaming replication) to distribute load and ensure availability, accommodating high concurrency by allowing multiple nodes to handle traffic. This approach simplifies configuration compared to manual scripting or parameter adjustments.
Option A (Use Post Create Command when provisioning the DB) is incorrect because post-create commands are for custom scripts, not optimal for handling concurrent connections.
Option B (Create a new Database Parameters profile) is incorrect because while it can tune settings, it's less efficient than HA for scaling concurrency.
Option C (Edit the API equivalent shell script) is incorrect as it's a manual and error-prone method compared to HA provisioning.
Option D is correct because a PostgreSQL HA instance natively supports high concurrency and availability.
Note: The typo "PostqreSQL" is assumed to mean "PostgreSQL."

質問 # 286
Which ports must be open between the NDB server and Controller VMs to facilitate iSCSI connections?
正解：B
解説：
According to the Nutanix Database Automation (NCP-DB) course, the ports 3205 and 3260 are required for iSCSI connections between the NDB server and the Controller VMs1. Port 3205 is used for the NDB iSCSI initiator service, which initiates the iSCSI sessions and sends SCSI commands to the Controller VMs1. Port
3260 is used for the iSCSI target service, which listens for incoming iSCSI requests and provides access to the storage devices on the Controller VMs1. The other options are not related to iSCSI connections. Port 22 is used for SSH, port 9440 is used for Prism Central, port 80 is used for HTTP, port 443 is used for HTTPS, port
5985 is used for WinRM HTTP, and port 5986 is used for WinRM HTTPS2. References:

質問 # 287
An administrator wants to migrate an existing MSSQL Server database to NDB.
How should the administrator complete this migration?
正解：B
解説：
To migrate an existing Microsoft SQL Server (MSSQL) database to NDB, the recommended approach is to:
* Provision a new database server VM and database: Use the NDB interface to provision a new VM and configure an MSSQL database instance on the Nutanix platform. This leverages NDB's automated provisioning capabilities to ensure compatibility with Nutanix infrastructure.
* Migrate the data: Transfer the data from the existing MSSQL database to the newly provisioned database. This can be achieved using native MSSQL tools (e.g., backup/restore, log shipping, or replication) or NDB's data migration features, such as cloning or restoring from a backup, depending on the source environment.
Other options are incorrect or incomplete:
* A. Use Nutanix Move to migrate the database server VM: Nutanix Move is designed for VM migration between platforms, not for database-specific migrations within NDB, which requires data migration to a new instance.
* C. Create a new database server VM and database then register it with NDB: Registering an existing VM with NDB does not handle data migration from the source MSSQL database.
* D. Backup your database VM and import it into Nutanix: Backing up the entire VM and importing it does not integrate the database with NDB's management framework, and data migration would still be required separately.
Thus, the verified answer is B, providing a structured migration process tailored to NDB's capabilities.
