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. Page
B. System
C. Database
D. Backup
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.
What is the terminology used for registering an existing database with Era?
A. Greenfield Database
B. Brownfield Database
C. Cloned Database
D. Source Database
Explanation:
In the context of Nutanix Era, the term “Brownfield Database” is used to refer to an existing database that is
registered with Era1. This process allows Era to bring Database as a Service (DBaaS) capabilities to your
existing database2. It’s important to note that before you register a database with Era, certain prerequisites
must be met3.
An administrator needs to register a SQL Server Single Node Database Server VM with NDB. Which condition must exist prior to the administrator completing this task?
A. Database files must exist in the Windows OS boot drive.
B. The login account provided must be a member of the sysadmin role.
C. The SQL service account should not have read privileges on the mount points.
D. SQL Server instance must be in single-user mode.
Explanation:
Before registering a SQL Server Single Node Database Server VM with NDB, it is necessary that the login
account provided for this task must be a member of the sysadmin role. This ensures the necessary permissions
are in place for managing and administering the SQL Server instance.

An administrator has been tasked with restoring an Oracle database that has recently failed. The administrator must restore the database to the prior day's state. Which two restore options could be used? (Choose two.)
A. Most Recent Time Available
B. Snapshot
C. Tail Logs Backup
D. Point in Time
Explanation:
The correct answer is B and D because they are the two restore options that can be used to restore an Oracle
database to the prior day’s state using Nutanix Era. A snapshot is a point-in-time copy of a database that is
stored in the Era Time Machine, which is a distributed file system that collects logs and snapshots from
databases. A point in time is a specific moment in time within the retention period of the SLA policy that is
applied to the database. By using either of these options, the administrator can select the snapshot or the point
in time that corresponds to the prior day’s state and restore the database from it. The other options are not
correct because they are not restore options that are available in Nutanix Era. Option A is not correct because Most Recent Time Available is not a restore option, but a clone option that creates a clone of the database
from the most recent snapshot or log backup. Option C is not correct because Tail Logs Backup is not a
restore option, but a backup option that captures the transaction logs of the database that have not been backed
up by the SLA policy.
An administrator needs to migrate a large 1/0-intensive database that doesn't support multi-disk layout. How should the storage be provisioned with Era to support the database while optimizing performance?
A. Volume Group
B. Volume Group with Load Balancing
C. Storage Spaces
D. vDisk based provisioning
Explanation:
In Nutanix Era, a Volume Group is the recommended storage provisioning method for a large I/O-intensive
database that doesn’t support a multi-disk layout1. A Volume Group in Nutanix Era is a collection of disks
that can be managed as a single entity, providing a way to aggregate the storage capacity of multiple disks
into a larger storage unit1. This allows for better performance optimization as it enables the database to
leverage the combined I/O capabilities of all the disks in the group1. It’s important to note that while other
options like Load Balancing, Storage Spaces, and vDisk based provisioning can also be used in certain
scenarios, a Volume Group is specifically designed for situations where a single, high-performance storage
unit is required1.
What does a Time Machine frozen status indicate?
A. The database is paused on the database VM.
B. The database was de-registered from NDB without removing the associated time machine.
C. The NDB agent is stopped on the database VM.
D. The Time Machine is paused and all automatic snapshot and log catch-up activities are halted.
Explanation:
A Time Machine frozen status indicates that the database that was associated with the Time Machine has been
de-registered from NDB, but the Time Machine itself has not been deleted. This means that the Time Machine
still contains the snapshots and logs of the de-registered database, but it cannot perform any further operations
on it. To resume the normal functioning of the Time Machine, the administrator can either re-register the
database with NDB, or delete the Time Machine and free up the storage space.
