NEW QUESTION # 16
An administrator was asked to change the snapshot schedule for a given database. The administrator discovered that the time machine is in a paused state.
How should the administrator change the schedule?
- A. Clone the Time Machine and define an appropriate schedule for the clone.
- B. Select the Time Machine; under Action select Update end define an appropriate schedule.
- C. Clone the database and define an appropriate schedule for the clone.
- D. Select Time Machine: Under actions Resume the Time Machine and then Update to define an appropriate schedule.
Answer: B
Explanation:
According to the Nutanix Database Automation (NCP-DB) learning documents, an administrator can change the snapshot schedule for a given database by selecting the Time Machine, then under Action, select Update and define an appropriate schedule1. This is because the Time Machine in Nutanix Era allows you to specify the number of backups or snapshots the time machine should take, the time of day it takes those snapshots, and the day of the week it takes weekly or monthly backups1. These options help you build a complete schedule of time machine capture operations1. Even if the Time Machine is in a paused state, the administrator can still update the schedule1. Cloning the Time Machine or the database is not necessary for changing the snapshot schedule1.
NEW QUESTION # 17
What is required to create an NDB Software Profile?
- A. Database server VM registered with NDB
- B. Patch file for the installed databases
- C. OS image registered with Prism Element
- D. Installer package for database software
Answer: D
Explanation:
An NDB Software Profile is a template of the OS and database engine that you can use to provision or clone database server VMs using NDB. To create a software profile, you need to upload an installer package for the database software that you want to use, such as SQL Server or Oracle. The installer package must be compatible with the OS image that you have registered with Prism Element. You do not need a database server VM registered with NDB, a patch file for the installed databases, or an OS image registered with Prism Element to create a software profile. Those are required for other tasks, such as creating a software profile version, registering a database server VM, or provisioning a database server VM.

NEW QUESTION # 19
An administrator is trying to register a database server VM with NDB.
Which file types will prevent the registration from being successful if located in the C:\ drive?
- A. System
- B. Backup
- C. Page
- D. Database
Answer: C
Explanation:
Page files are temporary files that Windows uses to store data that does not fit in the physical memory.
Page files can interfere with the registration of a database server VM with NDB, as they can cause errors or performance issues. Therefore, page files should be located in a separate drive or partition from the C:\ drive, where the NDB agent and other files are installed. System, database, and backup files do not prevent the registration of a database server VM with NDB, as long as they are not corrupted or incompatible with the NDB requirements.

An administrator would like to use Era for Copy Data Management operations on an Availability Group (AG) database.
The AG database is hosted on replicas with different named instances, as shown below:
* SQLAGNI\EMR
* SQLAGN2\EMR
* SQLAGN3\DW
SQLAGN3\DW is running the Analytics service that needs real-time data.
How should the administrator register the database in Era?
- A. Register the database as an Availability database.
- B. Register the SQLAGN3 from AG cluster and register the database as Availability database,
- C. Register the database as a Standalone database,
Answer: A
Explanation:
According to the Nutanix Database Automation (NCP-DB) learning documents, when dealing with an Availability Group (AG) database, the database should be registered as an Availability database1. This is because the AG database is hosted on replicas with different named instances, and registering it as an Availability database allows for Copy Data Management operations to be performed across all instances.
This is particularly important when services such as the Analytics service running on SQLAGN3\DW require real-time data1.

NEW QUESTION # 25
A development team has requested that an administrator provide them a copy of the production Finance database. The business requires that any financial data is masked before going into development.
How should the administrator create a clone with masked data for the development environment?
- A. 1. Create a masking script on the source DB VM, Dev VM or SW Profile VM.
2. Create the clone from the Time Machine and define the post-clone option with the full path\name of the masking script. - B. From the Time Machine, create a clone and paste the masking commands in the pre-clone field of the Pre-Post Commands section.
- C. 1. Create a script to mask the data.
2. Create the clone from the Time Machine and define the post-clone option with the full path\name of the masking script. - D. From the Time Machine, create a clone and paste the masking commands in the post-clone field of the Pre-Post Commands section.
Answer: A
Explanation:
According to the Nutanix Database Automation (NCP-DB) course, the Pre-Post Commands section allows the administrator to specify custom scripts that can be executed before or after the clone operation1. The masking script can be created on any of the VMs that have access to the source database, such as the source DB VM, the Dev VM, or the SW Profile VM2. The script should contain the commands to mask the sensitive data in the Finance database, such as replacing the real values with dummy values or encrypting the data2. The administrator can then create the clone from the Time Machine and define the post-clone option with the full path and name of the masking script1. This will ensure that the script is executed after the clone is created, and the data is masked before it is available for the development team1. The other options are not correct, as they either use the wrong field (pre- clone instead of post-clone), or do not specify where to create or store the masking script.

NEW QUESTION # 27
What behavior is observed when applying patch profiles as a Super Admin?
- A. Unpublished patches can be applied.
- B. Hidden patches can be applied.
- C. Deprecated patches can be applied.
- D. Published patches cannot be applied if currently deprecated.
Answer: D
Explanation:
In the context of Nutanix Database Automation (NCP-DB), a Super Admin has the authority to apply patch profiles. However, if a patch is marked as deprecated, even if it's published, it cannot be applied.
This is because deprecation is a status that indicates the patch is outdated or has been superseded by a newer version, and thus should not be used1. This behavior ensures that only the most up-to-date and secure patches are applied to the system, maintaining the integrity and security of the database environment1.
