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.)
Correct Answer: C,D
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.

Question 87
An administrator is asked to refresh a database everyday at 9:30PM with data from as close to the refresh time as possible. What is the best way achieve this requirement?
Correct Answer: D
This is because it allows the database to be refreshed at the exact time specified (9:30 PM) with the most recent data. The other options either perform the snapshot before the desired time or do not specify when the snapshot would occur. Please note that the exact answer might depend on the specific database system and its capabilities. Always refer to the database's documentation for the most accurate information.
Question 88
An administrator is experiencing issues with NDB and some of its operations. A case has been logged with Nutanix Support and a request has been made to gather a diagnostics bundle. Where are two valid places to generate and download a diagnostics bundle? (Choose two.)
Correct Answer: C,D
When an administrator experiences issues with NDB and Nutanix Support requests a diagnostics bundle, it can be generated from two valid locations. The NDB GUI provides an option under the administration or support section to create and download the bundle, offering a user-friendly interface. Alternatively, the NDB CLI allows generation via specific commands (e.g., era diagnostics collect), providing a scriptable approach. Both methods are supported for troubleshooting and support purposes. * Option A (Prism Central GUI) is incorrect because diagnostics for NDB are managed within NDB interfaces, not Prism Central. * Option B (Prism Element GUI) is incorrect as Prism Element focuses on cluster management, not NDB-specific diagnostics. * Option C (NDB GUI) is correct as it supports bundle generation via the UI. * Option D (NDB CLI) is correct as it supports bundle generation via command-line tools.

Question 89
Which step 's optional when completing the NDE Wizard?
Correct Answer: A
When completing the NDB (Nutanix Database Service) Wizard for initial setup or configuration, certain steps are mandatory to ensure the environment is properly configured, while others are optional based on specific needs. Network Segmentation is an optional step that allows for advanced network isolation and configuration, but it is not required for basic NDB deployment. Mandatory steps include specifying the NDB Cluster Name, selecting a Storage Container, and configuring Services (e.g., database services), as these are essential for NDB to function and manage databases. * Option A (Network Segmentation) is correct as it is an optional feature for advanced networking, not a required step in the wizard. * Option B (NDB Cluster Name) is incorrect because assigning a cluster name is a mandatory step to identify the NDB instance. * Option C (Storage Container) is incorrect because selecting a storage container is required for data storage and protection. * Option D (Services) is incorrect because configuring services (e.g., database engines) is a core requirement for NDB operation. Note: The question mentions "NDE Wizard," which is assumed to be a typo for "NDB Wizard" based on context.

Question 90
A new administrator is tasked with changing the NDB GUI password via CLl. Which command will accomplish this task?
Correct Answer: D
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.
