NetApp NS0-004 Online Questions & Answers

• Question 41:

  A customer has a NetApp AFF system with a large portion of space that is used by inactive data. The customer wants to free up space for more active data on the system and still be able to access inactive data.

  Which NetApp product should this customer use to free up space in a cost-effective way?

  A. BlueXP tiering
  B. Cloud Volumes ONTAP
  C. BlueXP backup and recovery
  D. BlueXP edge caching
  A. BlueXP tiering

  ---

  Explanation

  BlueXP tiering is a service that extends your data center to the cloud by automatically tiering inactive data from on-premises ONTAP clusters to object storage. This frees valuable space on the cluster for more workloads, without making

  changes to the application layer. BlueXP tiering can reduce costs in your data center and enables you to switch from a CAPEX model to an OPEX model. BlueXP tiering leverages the capabilities of FabricPool, which is a NetApp Data Fabric

  technology that enables automated tiering of data to low-cost object storage. Active (hot) data remains on the local tier (on-premises ONTAP aggregates), while inactive (cold) data is moved to the cloud tier -- all while preserving ONTAP data

  efficiencies.

  A. Flash Cache
  B. SnapVault
  C. FlexCache
  D. Flash Pool
  C. FlexCache

  ---

  Explanation

  FlexCache is a NetApp technology that will enable the company to prepopulate a subset of the data from their remote factories to their AI Center of Excellence. FlexCache is a feature of NetApp ONTAP that allows you to create a cache volume on a local or remote cluster and populate it with data from a source volume on another cluster. FlexCache enables faster access to data by reducing latency and network bandwidth consumption. FlexCache also allows you to select a subset of data from the source volume to cache, based on your business needs. FlexCache can be used for various use cases, such as AI and machine learning, where you need to access a subset of data from a large data lake for training or inference.

• Question 47:

  What are two data types? (Choose two.)

  A. file
  B. object
  C. disk
  D. LAN
  E. RAID
  A. file
  B. object

  ---

  Explanation

  A file is a data type that represents a collection of data stored on a disk or other storage device. A file can have a name, an extension, a size, and other attributes. A file can contain any kind of data, such as text, images, audio, video, etc. A

  file can be opened, read, written, closed, deleted, or moved by a program. An object is a data type that represents an instance of a class, which is a blueprint for creating objects. An object can have properties, which are variables that store

  data, and methods, which are functions that perform actions on the object. An object can interact with other objects by sending and receiving messages. An object can inherit properties and methods from its parent class, or override them with

  its own definitions.

• Question 50:

  A customer wants to use FabricPool technology with NetApp StorageGRID. All objects must be erasure coded. What is the minimum number of sites required to deploy the StorageGRID solution while providing site redundancy?

  A. 1
  B. 2
  C. 3
  D. 4
  C. 3

  ---

  Explanation

  FabricPool is an ONTAP feature that tiers inactive data to an object store such as StorageGRID. StorageGRID uses erasure coding to protect data by slicing an object into data fragments and parity fragments, and spreading them across

  Storage Nodes. To use erasure coding, the storage pool must include three or more sites, or exactly one site. Two sites are not supported. Therefore, the minimum number of sites required to deploy the StorageGRID solution with FabricPool

  and erasure coding is three.
