Answer : A

S3 Object Lock is a StorageGRID feature that enables a compliant information lifecycle management (ILM) policy to prevent object deletion. S3 Object Lock allows you to apply a retention period and a legal hold to individual objects or object versions in buckets with S3 Object Lock enabled. During the retention period, objects cannot be overwritten or deleted unless the legal hold is in effect. If an object is under a legal hold, it cannot be deleted even after the retention period expires. S3 Object Lock helps you to meet regulatory compliance, privacy, and data protection requirements for your object data.Reference=Manage objects with S3 Object Lock,Example 7: Compliant ILM policy for S3 Object Lock,NetApp StorageGRID ILM on tape

Answer : D

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.Reference=What is Cloud Volumes Service for AWS?,Cloud Volumes Service for AWS Documentation,Cloud Volumes Service for Google Cloud Documentation,Cloud Volumes Service for Azure Documentation

Answer : A

= 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.Reference=SANtricity OS Dynamic Disk Pools | TR-4652 - NetApp,How to increase priority for disk reconstruction - NetApp Knowledge Base.

Answer : B

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.Reference=Bucket and group access policies,Use bucket and group access policies,Example group policies.

Answer : B, C

Advanced Disk Partitioning (ADP) is a feature that enables ONTAP to partition a disk into multiple logical units and use them for different purposes. ADP has two main benefits for AFF or FAS systems:

It optimizes storage capacity by reducing the number of disks required for the root aggregates, which store the system and configuration data. By using ADP, the root aggregate can share the same disk with a data aggregate, which stores the user data. This frees up more disks for data aggregates and increases the usable space for data.

It reduces RAID parity overhead by creating smaller RAID groups with partitions instead of whole disks. This reduces the amount of parity data that needs to be written and read, which improves the performance and efficiency of the system.Reference=What are the rules for Advanced Disk Partitioning?,Considerations for automatic drive assignment and ADP systems in ONTAP 9.4 and later,NetApp AFF and Advanced Drive Partition v2, part 1

Answer : D

= Cisco UCS Director is a heterogeneous platform for private cloud Infrastructure as a Service (IaaS) that supports a variety of hypervisors and Cisco and third-party servers, network, storage, and converged infrastructure. It simplifies IaaS, automates IT workflows, and enables hybrid IT with Cisco CloudCenter and other Cisco ONE Enterprise Cloud Suite offers. It also provides a single point of control for managing FlexPod and other converged infrastructure solutions across data center, remote, and edge environments.Reference=Cisco UCS Director - Cisco,Cisco UCS Director Data Sheet - Cisco,FlexPod overview and architecture - NetApp

Answer : C

n= 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.Reference=WORM storage | NetApp Documentation,WORM storage - NetApp
