質問 # 33
Which storage type provides access using Amazon Simple Storage Service (Amazon S3) APIs?
- A. SAN
- B. object
- C. DAS
- D. NAS
正解：B
解説：
Explanation
= Object storage is a type of storage that provides access using Amazon S3 APIs. Object storage stores data as objects, which consist of data and metadata. Object storage is designed for scalability, durability, and cost-effectiveness. Object storage is suitable for storing unstructured data, such as images, videos, documents, and backups. Object storage does not use a hierarchical file system, but rather a flat namespace that allows users to access objects by unique identifiers.

質問 # 34
A customer wants to use a NetApp cloud solution for their CIFS and iSCSI data but has a very limited staff.
Which NetApp cloud solution meets these requirements?
- A. Cloud Volumes ONTAP
- B. BlueXP observability
- C. Cloud Volumes Service
- D. BlueXP classification
正解：C
解説：
Explanation
Cloud Volumes Service is a fully managed cloud storage service that provides SMB/CIFS and NFS file services for your cloud applications. It is designed for customers who want to use NetApp cloud solutions for their CIFS and iSCSI data but have a very limited staff. Cloud Volumes Service simplifies and automates the deployment, management, and scaling of your file systems, while delivering high performance, availability, security, and data protection. You can also leverage NetApp's data management capabilities, such as snapshots, clones, replication, and backup, to enhance your data lifecycle management.

質問 # 35
What owns the file system while provisioning SAN?
- A. volume
- B. LUN
- C. ONTAP software
- D. host
正解：D
解説：
Explanation
= When provisioning SAN, the host owns the file system. A LUN is a logical unit of storage that is presented to the host as a SCSI device. The host can format the LUN with any file system it supports, such as NTFS, ext4, or XFS. The ONTAP software does not manage the file system on the LUN, but only provides the block-level access to the LUN. The volume is a logical container for one or more LUNs, but it does not own the file system either. References = SAN Concepts, LUNs and Volumes
質問 # 36
Which feature does StorageGRID use to distribute copies of object data?
- A. storage lifecycle management (SLM)
- B. application lifecycle management (ALM)
- C. information lifecycle management (ILM)
- D. object lifecycle management (OLM)
正解：C
解説：
Explanation
Information lifecycle management (ILM) is a feature of StorageGRID that enables you to create and apply policies that determine how objects are stored, replicated, protected, and distributed across the grid and public clouds. ILM policies can also specify how long objects are retained, when they are deleted, and how they are encrypted. ILM policies are based on object metadata, such as bucket name, object name, size, or custom tags.
ILM policies help you optimize the performance, availability, durability, and cost of your object storage. References = Information lifecycle management overview - NetApp, StorageGRID - Object Storage

質問 # 37
A customer wants to modernize the SAN environment and transition iSCSI-based workloads to NVMe-over-TCP. Which NetApp storage systems should be used to meet these requirements?
- A. ONTAP software
- B. SANtricity OS
- C. StorageGRID
- D. Element software
正解：A
解説：
Explanation
ONTAP software is a NetApp storage system that supports NVMe-over-TCP, which is a protocol that allows remote direct memory access for data using an Ethernet TCP link. ONTAP software enables customers to upgrade their iSCSI-based workloads to NVMe-over-TCP without requiring any special hardware or network changes. ONTAP software also provides other benefits such as data protection, efficiency, and scalability for SAN environments.

質問 # 39
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 SSDs to the existing AFF cluster.
- C. Add a new FAS system to the existing AFF cluster.
- D. Expand the cluster with a new AFF system.
正解：C
解説：
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. References = Storage Efficiencies - NetApp, Data Archiving: Cost-Effective Cloud Storage - NetApp, AFF Systems and Cloud Volumes ONTAP | NetApp.
質問 # 40
Which two access policies are supported by StorageGRID? (Choose two.)
- A. group
- B. service
- C. ILM
- D. export
- E. bucket
正解：E
解説：
Explanation
StorageGRID supports two kinds of access policies: bucket policies and group policies. Bucket policies are attached to buckets and control access by users in the bucket owner account or other accounts to the bucket and the objects in it. Group policies are attached to a group in the account and allow that group to access specific resources owned by that account. Both bucket and group policies use the Amazon Web Services (AWS) policy language and are written in JSON. References = Bucket and group access policies, Use bucket and group access policies, Example group policies.

Which NetApp tool has the capability to learn, recommend, and apply Performance Service Levels on multiple clusters?
- A. BlueXP observability
- B. ONTAP System Manager
- C. BlueXP classification
- D. Active IQ Unified Manager
正解：D
