• Question 3:

  Which protocol is supported in StorageGRID?

  A. HTTPS
  B. CIFS
  C. FTP
  D. NFS
  A. HTTPS

  ---

  Explanation

  HTTPS and NFS are two protocols that are supported in StorageGRID. HTTPS is the protocol used for secure communication between clients and StorageGRID nodes. NFS is the protocol supported by the StorageGRID NAS protocol bridge, which enables object access to files stored on NAS devices using the Amazon S3 API.

• Question 4:

  Which NetApp feature provides WORM functionality at the volume level?

  A. SnapVault
  B. FlexGroup
  C. SnapLock
  D. SyncMirror
  C. SnapLock

  ---

  Explanation

  SnapLock is a NetApp feature that provides WORM (write once, read many) functionality at the volume level. WORM storage enables you to retain files in unmodified form for a specified retention period. SnapLock protects WORM files at the

  file level and prevents them from being modified, even after the retention period has expired. SnapLock is powered by a tamper-proof clock that determines when the retention period for a WORM file has elapsed. SnapLock is available for

  Cloud Volumes ONTAP systems and supports both NFS and CIFS protocols.

• Question 5:

  A storage administrator wants to expand an existing NetApp ONTAP AFF cluster with cost- effective nearline storage for archiving purposes.

  What should the administrator do to accomplish this task?

  A. Upgrade the AFF controllers to a higher system.
  B. Add a new FAS system to the existing AFF cluster.
  C. Expand the cluster with a new AFF system.
  D. Add SSDs to the existing AFF cluster.
  B. Add a new FAS system to the existing AFF cluster.

  ---

  Explanation

  Adding a new FAS system to the existing AFF cluster is a way to expand the storage capacity with cost- effective nearline storage for archiving purposes. A FAS system can use HDDs as the performance tier and tier cold data to cloud object

  storage using FabricPool, which is a NetApp data tiering technology that reduces the amount of physical capacity taken up by data. This way, the administrator can leverage the storage efficiencies of ONTAP and the low-cost storage of the

  cloud to archive data that is not frequently accessed. The AFF and FAS systems can be managed by the same ONTAP cluster and provide seamless data access and protection.

• Question 6:

  Which technology uses on-premises bare-metal hardware to abstract the operating system from the underlying hardware?

  A. hyperscaler
  B. hypervisor
  C. container
  D. supervisor
  B. hypervisor

  ---

  Explanation

  A hypervisor is a software layer that enables multiple operating systems to run on the same physical hardware by creating virtual machines (VMs) that are isolated from each other. A hypervisor abstracts the operating system from the

  underlying hardware, allowing for greater flexibility, efficiency, and scalability of the virtualized environment. NetApp supports several hypervisor platforms, such as VMware ESXi, KVM, and Hyper-V, and provides storage solutions that

  integrate with them.

• Question 7:

  A data administrator needs to store customer financial records that are subject to SEC regulations. All files must be retained in an unalterable state for 6 years and must stay easily accessible.

  Which feature should the administrator configure?

  A. SnapLock Compliance
  B. SnapLock Enterprise
  C. NetApp Volume Encryption (NVE)
  D. NetApp Storage Encryption (NSE)
  A. SnapLock Compliance

  ---

  Explanation

  SnapLock Compliance is a NetApp feature that enables you to store customer financial records that are subject to SEC regulations. SnapLock Compliance provides WORM (write once, read many) functionality at the volume level, which

  means that files cannot be modified, deleted, or overwritten for a specified retention period. SnapLock Compliance also ensures that files are easily accessible and searchable, and that they comply with the SEC Rule 17a-4, which requires

  financial firms to preserve certain records in a non-rewriteable and non-erasable format.

  storage requirements..

• Question 8:

  What are two NetApp on-premises data storage systems that can be discovered and managed in NetApp BlueXP? (Choose two.)

  A. E-Series
  B. Element clusters
  C. Astra Data Store
  D. StorageGRID
  A. E-Series

  ---

  Explanation

  NetApp BlueXP is a unified control plane that provides a hybrid multicloud experience for storage and data services across on-premises and cloud environments. It delivers operational simplicity combined with powerful and intelligent data

  management, protection, mobility, and governance services. NetApp BlueXP can discover and manage NetApp on-premises data storage systems that support the Amazon S3 API, such as E- Series and StorageGRID. E-Series is a hybrid-

  flash array that offers simple, fast, and reliable SAN storage for dedicated, high-bandwidth applications like data analytics, video surveillance, and HPC. StorageGRID is a software-defined object storage suite that supports a wide range of

  use cases across public, private, and hybrid multicloud environments. StorageGRID offers native support for the Amazon S3 API and delivers industry-leading innovations such as automated lifecycle management to store, secure, protect,

  and preserve unstructured data cost effectively over long periods.

• Question 9:

  A storage administrator is asked to provision storage on an E-Series system. Which disk layout type provides the fastest rebuild time after disk failure?

  A. Dynamic Disk Pools (DDP)
  B. volume group
  C. RAID 5
  D. Advanced Disk Partitioning (ADP)
  A. Dynamic Disk Pools (DDP)

  ---

  Explanation

  Dynamic Disk Pools (DDP) is a disk layout type that provides the fastest rebuild time after disk failure on an E-Series system. DDP distributes data, parity, and spare capacity across a pool of disks, instead of using dedicated parity and spare

  disks. This enables faster and more efficient reconstruction of data in the event of a disk failure, as well as better performance and load balancing. DDP also reduces the risk of data loss due to multiple disk failures, as it can tolerate any

  number of disk failures up to the pool's protection level.

  An administrator needs to upgrade the system hardware of a StorageGRID system to the latest version of firmware. Which software is used for this upgrade?

  A. NetApp Element
  B. NetApp SANtricity
  C. NetApp ONTAP
  D. Microsoft Windows
  B. NetApp SANtricity

  ---

  Explanation

  NetApp SANtricity is the software that is used to upgrade the system hardware of a StorageGRID system to the latest version of firmware. NetApp SANtricity is a web-based data management tool that enables customers to provision storage

  systems and perform common management tasks. NetApp SANtricity provides a simple, intuitive, and centralized interface for managing E-Series storage systems, which are used in StorageGRID appliances. NetApp SANtricity allows
