NEW QUESTION # 177
How long is the default continuous recovery for the Gold SLA in Era Time Machine?

A. 30 days
B. 90 days
C. 60 days
D. 15 days

Answer: A

Explanation:
The default continuous recovery for the Gold SLA in Era Time Machine is 30 days1. This means that the system keeps a continuous recovery point for the last 30 days, allowing you to restore your database to any point within this period1.

NEW QUESTION # 178
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. Mount an iSCSI LUN and extend the database onto the new LUN.
B. Leverage the scaling ability built into NDB to resize existing vDisks.
C. Create a new. larger database and migrate.
D. Extend the size by adding new vDisks.

Answer: B

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 # 179
What must be configured in Prism Element to allow the NDB server and CVMs to facilitate iSCSI connections?

A. Secondary DNS IP
B. Virtual IP
C. Data Services IP
D. Backplane IP

Answer: C

Explanation:
To enable iSCSI connections between the Nutanix Database Service (NDB) server, Controller VMs (CVMs), and Prism Element, a Data Services IP must be configured in Prism Element. The Data Services IP acts as a cluster-wide address that facilitates iSCSI target discovery and connectivity. It is used by Nutanix Volumes (a block storage service) to present storage to external clients or services, such as the NDB server, via the iSCSI protocol. This IP ensures that iSCSI traffic is routed correctly and remains available even if a CVM fails, as ownership of the Data Services IP can move to another CVM in the cluster.
Configuring the Data Services IP is a prerequisite for integrating NDB with a Nutanix cluster, as NDB relies on iSCSI to manage database storage operations like provisioning and cloning. Without this configuration, the NDB server cannot establish the necessary connections to the CVMs for database-related tasks. Options like Virtual IP, Secondary DNS IP, and Backplane IP are not relevant in this context:
* Virtual IP: This is typically associated with high-availability setups for applications, not iSCSI connectivity.
* Secondary DNS IP: This pertains to network resolution, not storage connectivity.
* Backplane IP: This is an internal network IP for cluster communication, not for external iSCSI access.
Thus, the correct and verified answer is the Data Services IP.

NEW QUESTION # 180
What does a Time Machine frozen status indicate?

A. The database is paused on the database VM.
B. The Time Machine is paused and all automatic snapshot and log catch-up activities are halted.
C. The NDB agent is stopped on the database VM.
D. The database was de-registered fromNDB withoutremoving the associated time machine.

Answer: D

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.

NEW QUESTION # 181
An administrator has received a request to clone a source production database to an existing development server.
Which two actions must be taken to complete this task?

A. The development server must be registered by Era in order to receive the clone.
B. The development server must be authorized for the database Time Machine.
C. The development server must be registered by Era and authorized to host clones from the Time Machine.
D. The development server must have the IP and credentials provided during cloning.

Answer: A,D

Explanation:
According to the Nutanix Database Automation (NCP-DB) Learning documents12, to clone a source production database to an existing development server, the following actions must be taken:
A: The development server must be registered by Era in order to receive the clone1. This is because Nutanix Era is a database management tool that manages the lifecycle of databases and their copies. Registering the development server with Era allows it to manage the database on that server.
D: The development server must have the IP and credentials provided during cloning2. This is necessary for Era to access the development server and perform the cloning operation. The IP address and credentials are used to establish a connection to the development server. Without these details, Era would not be able to access the server and perform the cloning operation.
