What is the primary architectural benefit of using technologies like RDMA (Remote Direct Memory Access) and GPUDirect Storage in a high-performance AI training cluster?

• A.They reduce the power consumption of the storage array by offloading checksum calculations.
• B.They allow GPUs to communicate directly with each other and with NVMe storage, bypassing the host CPU and system memory, which significantly reduces I/O latency and CPU overhead.
• C.They enable the use of lower-cost Ethernet switches in place of InfiniBand fabrics without any performance degradation.
• D.They automatically encrypt data in-flight between the GPU servers and the storage system.

An architect is designing a comprehensive AI platform for a large enterprise. The platform must support the entire data lifecycle, from ingest at the edge to a central data lake, and finally to a high- performance training cluster.
The requirements are:
- Edge Ingest: Data must be collected at remote sites and efficiently replicated to the core.
- Data Lake: A central, petabyte-scale repository for unstructured data, accessible via the S3 protocol.
- Training Cluster: A high-performance compute cluster that requires low-latency, parallel file access to training datasets.
- Data Traceability: All datasets used for training must be immutably versioned.
Which combination of NetApp technologies and protocols should the architect choose to build this solution? (Select all that apply.)

• A.Use NetApp FlexCache to tier cold data from the data lake to the public cloud.
• B.Use NetApp Snapshots on the training dataset volumes to create immutable, point-in-time versions for traceability.
• C.Use NetApp ONTAP systems at the edge and NetApp SnapMirror to replicate data to the core data center.
• D.Use iSCSI as the primary protocol for the data lake to ensure maximum compatibility.
• E.Use NetApp StorageGRID to create the petabyte-scale, S3-accessible data lake at the core.
• F.Use a NetApp E-Series system with a parallel file system (like BeeGFS) to provide high- performance, parallel file access for the training cluster.

An AI architect is reviewing the design for a new data lake. The primary requirement is to store petabytes of unstructured data (images, video, sensor logs) in a highly durable, scalable, and cost- effective manner. The data will be accessed via S3 API by various data processing and analytics applications.
The initial design proposes using a traditional Network Attached Storage (NAS) filer with a large number of disks. The architect reviews the proposal:
Proposed_System: Traditional NAS Filer
Protocol: NFSv4
Scalability_Model: Scale-up
Metadata_Handling: Centralized in filer head
Cost_per_GB: Moderate
Why is this proposed system a poor choice for a petabyte-scale data lake?

• A.A traditional scale-up NAS system will face scalability and cost-effectiveness challenges at the petabyte scale compared to an object storage system.
• B.The S3 API cannot be used to access data stored on an NFS file system.
• C.A NAS filer cannot be deployed on-premises.
• D.NFS is incapable of storing image or video files.
