Try and practice the latest Network Appliance : NS0-901 real questions & answers

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

An AI infrastructure architect is tasked with designing a solution to address two critical challenges in a large, multi-petabyte AI environment:
1. Cost: A significant portion of the data on the high-performance all-flash storage is inactive but must remain online. The cost of storing this cold data on the performance tier is prohibitive.
2. Traceability: Data scientists need a simple, space-efficient way to version their datasets at key points in their workflow to ensure reproducibility.
The environment consists of NetApp AFF A-Series and NetApp StorageGRID systems.
Which combination of NetApp technologies should the architect implement to solve both challenges simultaneously? (Select all that apply.)

• A. Use NetApp SnapMirror to replicate volumes from the AFF systems to StorageGRID for archival.
• B. Use NetApp XCP to periodically move cold data from the AFF systems to StorageGRID.
• C. Implement NetApp FlexClone to create full, writable copies of datasets for each experiment.
• D. Train data scientists to use NetApp Snapshots to create point-in-time, read-only versions of their data volumes.
• E. Use BlueXP backup and recovery to create backups on StorageGRID, then delete the original volumes from the AFF systems.
• F. Implement NetApp FabricPool to automatically tier cold data blocks from the AFF systems to StorageGRID.

The data pipeline that updates the vector database from the StorageGRID data lake fails. An MLOps engineer uses the BlueXP API to check the status of the copy and sync job responsible for moving new documents to a staging area for processing.
The API returns the following JSON response:
{
"id": "rel_5f8g7h2k",
"volumeName": "product_docs_source",
"svmName": "svm_datalake",
"relationshipStatus": "FAILED",
"s3Location": "s3://vector-staging-bucket/latest/",
"progress": 87,
"failureMessage": "Sync failed.
Target credentials invalid. Check permissions for data broker 'db-gcp-1' on target bucket 'vector- staging-bucket'."
}
Based on this output, what is the most direct cause of the pipeline failure?

• A. The source StorageGRID system is offline.
• B. The vector database embedding process has crashed.
• C. The network connection between the data broker and the StorageGRID system is blocked by a firewall.
• D. The BlueXP data broker service account or role lacks the necessary IAM permissions to write to the target S3 bucket.

The firm wants to extend the "Advisor Assistant" to include a new batch processing feature. Every night, the system must analyze every client portfolio against a set of 50 different risk models and generate a compliance report. This is a highly parallel, read-intensive workload. The architect must design a data workflow that is efficient and does not impact the production chatbot environment. Which sequence of actions and technologies provides the most effective solution?

• A. Create a NetApp Snapshot of the portfolio database volume, create a FlexClone from that snapshot, mount the FlexClone to the analysis pods, and run the batch job.
• B. Create a full physical copy of the client portfolio database to a separate volume, mount it to the compute nodes, and run the analysis.
• C. Run the analysis job directly against the production portfolio database during off-peak hours.
• D. Use NetApp SnapMirror to replicate the portfolio database volume to the DR site, and run the analysis jobs there.

To comply with the security mandate, the architect must design a process to prevent client PII from the portfolio database from ever being included in the context sent to the LLM. Which two actions are required to build a robust and automated solution for this? (Choose 2.)

• A. Implement a data preparation step in the RAG pipeline that programmatically masks or excludes any data fields tagged as PII before the context is constructed.
• B. Use BlueXP classification to perform an initial scan of the portfolio database to identify and tag all columns containing PII.
• C. Fine-tune the LLM on a sanitized dataset to teach it to ignore PII.
• D. Rely on a disclaimer in the chatbot UI telling advisors not to enter queries related to specific clients.
• E. Move the entire client portfolio database to an encrypted, air-gapped system.
